[0011] Another object of the present invention is to provide a processing device.

[0012] The present invention provides the following technical solutions: A processing device comprises a support, a clamping and fixing mechanism and the above-mentioned climbing mechanism, wherein the clamping and fixing mechanism and the climbing mechanism are both arranged on the support, and the clamping and fixing mechanism is located on the side of the first climbing member facing away from the second climbing member.

[0016] The embodiments of the present invention have the following beneficial effects: In the above climbing mechanism, the first climbing member is relatively fixed to the support member when the first clamping member is engaged with the tooth groove, and the second climbing member is relatively fixed to the support member when the second clamping member is engaged with the tooth groove. When in use, the first clamping driver drives the first clamping member to separate from the corresponding tooth groove, and releases the connection between the first climbing member and the support member. At this time, the climbing driver drives the first climbing member away from the second climbing member. With the second climbing member as the force support, the first climbing member climbs along the support member and lifts the raw material upward. Subsequently, the first clamping driver drives the first clamping member to clamp into another tooth groove, so that the first climbing member remains connected to the support member. The second clamping driver drives the second clamping member to separate from the corresponding tooth groove, and releases the connection between the second climbing member and the support member.

[0027] Example 1 Please also read Figure 1 and Figure 2 This embodiment provides a climbing mechanism 100, which is applied to a small metal part 20 (see Figure 7 ). The small metal piece 20 is processed section by section from a rod-shaped raw material 10. During processing, the top of the raw material 10 is higher than the surface of the processing device by a certain distance. After the exposed part of the raw material 10 is processed by CNC to form the small metal piece 20, the small metal piece 20 is removed, and then the climbing mechanism 100 lifts the raw material 10 upward to a fixed height, so that the top of the raw material 10 is higher than the surface of the processing device by a certain distance again, so as to process the next small metal piece 20.

[0028] In addition to being used for lifting materials, in other embodiments of the present application, the climbing mechanism 100 can also be used as a load end, which can drive the moving parts to move fixed distances one by one.

[0029] Please also read Figure 2 and Figure 3 Specifically, the climbing mechanism 100 includes a supporting assembly 110 , a first climbing assembly 120 , a second climbing assembly 130 and a climbing driving assembly 140 .

[0030] The first climbing assembly 120 and the second climbing assembly 130 climb along the support assembly 110. Both the first climbing assembly 120 and the second climbing assembly 130 can be connected to or separated from the support assembly 110, and the first climbing assembly 120 is located above the second climbing assembly 130. The climbing drive assembly 140 is connected to the first climbing assembly 120 and the second climbing assembly 130, respectively, and can drive the first climbing assembly 120 and the second climbing assembly 130 to move closer to or away from each other.

[0031] When in use, the second climbing assembly 130 is connected to the support assembly 110, and the first climbing assembly 120 is separated from the support assembly 110. With the second climbing assembly 130 as the support, the climbing drive assembly 140 drives the first climbing assembly 120 away from the second climbing assembly 130, so that the first climbing assembly 120 rises. On this basis, the first climbing assembly 120 lifts the raw material 10 upward.

[0032] After that, the first climbing assembly 120 is connected to the support assembly 110, and the second climbing assembly 130 is separated from the support assembly 110. With the first climbing assembly 120 as the force support, the climbing drive assembly 140 drives the second climbing assembly 130 to approach the first climbing assembly 120, so that the second climbing assembly 130 rises.

[0033] The first climbing assembly 120 and the second climbing assembly 130 are located at an equal distance from each other and a distance from each other, and are equal to the height at which the raw material 10 is lifted upward.

[0034] Please combine Figure 4 Specifically, the support assembly 110 includes a vertically arranged support member 111, and a plurality of tooth grooves 111a are arranged on the side of the support member 111. The first climbing assembly 120 and the second climbing assembly 130 are connected to the support member 111 by being inserted into the tooth grooves 111a, and are separated from the support member 111 by being disengaged from the tooth grooves 111a.

[0035] In some specific embodiments, the support member 111 is a rack, and a plurality of tooth grooves 111a are provided on both sides of the support member 111. The tooth grooves 111a on one side are for the first climbing assembly 120 to be inserted into, and the tooth grooves 111a on the other side are for the second climbing assembly 130 to be inserted into. In addition, the height of the log 10 being lifted upward is equal to an integral multiple of the spacing between two adjacent tooth grooves 111a.

[0036] Furthermore, the support member 111 is provided with an indicator scale 111b, and the tooth grooves 111a on the two sides of the support member 111 are numbered from bottom to top. Among them, the N-numbered tooth groove 111a for the first climbing component 120 to be inserted into is higher than the N-numbered tooth groove 111a for the second climbing component 130 to be inserted into, and the height difference remains unchanged.

[0037] In some other specific implementations, the tooth groove 111 a may be provided on only one side of the support member 111 , so that both the first climbing assembly 120 and the second climbing assembly 130 can be inserted therein.

[0038] Please refer again Figure 2 and Figure 3 In this embodiment, the support assembly 110 further includes a vertically arranged guide column 112 and a first linear bearing 113 and a second linear bearing 114 slidably sleeved on the guide column 112. The first linear bearing 113 is fixedly connected to the first climbing assembly 120, and the second linear bearing 114 is fixedly connected to the second climbing assembly 130.

[0039] In the vertical direction, the guide column 112 guides the first climbing assembly 120 and the second climbing assembly 130, so that the first climbing assembly 120 and the second climbing assembly 130 can be raised and lowered smoothly. In the horizontal direction, the guide column 112 limits the first climbing assembly 120 and the second climbing assembly 130, so that the first climbing assembly 120 and the second climbing assembly 130 can be stably matched with the support member 111.

[0040] In other embodiments of the present application, the guide column 112 may not be provided, but the tooth grooves 111a for the first climbing assembly 120 to be inserted into are provided on the opposite side surfaces of the support member 111. Accordingly, the first climbing assembly 120 is inserted into the tooth grooves 111a on both sides of the support member 111 at the same time to stably cooperate with the support member 111. The second climbing assembly 130 is similar, and will not be described in detail here.

[0041] Specifically, the first climbing assembly 120 includes a first climbing member 121 , a first clamping driving member 122 and a first clamping member 123 .

[0042] The first climbing member 121 is fixedly connected to the first linear bearing 113. The first clamping driving member 122 is fixedly arranged on the first climbing member 121, and the driving end of the first clamping driving member 122 is connected to the first clamping member 123. The first clamping member 123 is engaged with or separated from the tooth groove 111a under the drive of the first clamping driving member 122.

[0043] In some specific embodiments, the first climbing member 121 is a pull plate, and the pull plate is horizontally arranged, and can pull the second climbing assembly 130. The first clamping driving member 122 is a pull plate positioning cylinder, which is fixed to the side of the pull plate, and its piston rod is horizontally retracted. The first clamping member 123 is a pull plate tooth block, and the pull plate tooth block is connected to the piston rod of the pull plate positioning cylinder.

[0044] Please combine Figure 4Furthermore, the tooth groove 111a has an inclined support surface 111c. When the first clamping member 123 is engaged with the tooth groove 111a, it abuts against the support surface 111c and fits with the support surface 111c, and the first clamping member 123 and the groove bottom of the tooth groove 111a are in clearance.

[0045] During long-term use, as the first clamping member 123 is constantly engaged with and separated from the tooth grooves 111 a, the bottom of the first clamping member 123 (the surface in contact with the support surface 111 c ) is easily worn, causing the actual size of the first clamping member 123 in the vertical direction to become smaller.

[0046] At this time, if the depth of the first clamping member 123 inserted into the tooth groove 111a remains unchanged, there will be a gap between the first clamping member 123 and the support surface 111c of the tooth groove 111a. The support surface 111c cannot support the first clamping member 123, causing the entire first climbing assembly 120 including the first clamping member 123 to sink to a certain height, thereby causing a deviation in the height of the raw material 10 being lifted upward.

[0047] To this end, the support surface 111c is tilted and the first clamping member 123 is matched with the bottom clearance of the tooth groove 111a, thereby allowing the first clamping driving member 122 to drive the first clamping member 123 to be more deeply engaged in the tooth groove 111a until the first clamping member 123 abuts against the support surface 111c, while the height of the first clamping member 123 remains unchanged.

[0048] Furthermore, the first climbing component 120 also includes a first fixing member 124 , and the first fixing member 124 is fixedly connected to the first climbing member 121 .

[0049] The first clamping driving member 122 is fixedly disposed on the first fixing member 124 , and is connected to the first climbing member 121 via the first fixing member 124 .

[0050] In addition, the first clamping member 123 is slidably disposed on the first fixing member 124. The supporting force applied by the supporting member 111 to the first clamping member 123 is transmitted to the first climbing member 121 via the first fixing member 124, so as to prevent the first clamping driving member 122 from being damaged by tangential pressure.

[0051] Furthermore, the first climbing component 120 further includes a lifting member 125. The lifting member 125 is fixedly arranged on the top surface of the first climbing member 121, and the top end surface of the lifting member 125 is provided with a groove for the raw material 10 to be embedded, and the raw material 10 is lifted up when the raw material 10 is limited.

[0052] In some specific embodiments, a plurality of lifting members 125 , for example, 16 lifting members 125 , are disposed on the top surface of the first climbing member 121 , and a plurality of raw materials 10 can be lifted up simultaneously through the first climbing member 121 .

[0053] Similarly, the second climbing assembly 130 includes a second climbing member 131 , a second clamping driving member 132 and a second clamping member 133 .

[0054] The second climbing member 131 is fixedly connected to the second linear bearing 114. The second clamping driving member 132 is fixedly arranged on the second climbing member 131, and the driving end of the second clamping driving member 132 is connected to the second clamping member 133. The second clamping member 133 is engaged with or separated from the tooth groove 111a under the drive of the second clamping driving member 132.

[0055] In some specific embodiments, the second climbing member 131 is a push plate, and the push plate is horizontally arranged, and can push the first climbing assembly 120. The second holding driving member 132 is a push plate positioning cylinder, which is fixed to the side of the push plate, and its piston rod is horizontally retracted. The second holding member 133 is a push plate tooth block, and the push plate tooth block is connected to the piston rod of the push plate positioning cylinder.

[0056] Optionally, the material of the rack, pull plate tooth block and push plate tooth block is SKD-11, with a hardness of HRC58, and has sufficient load-bearing capacity and anti-deformation ability. However, the material of the rack, pull plate tooth block and push plate tooth block can also be other materials as long as it has sufficient load-bearing capacity and anti-deformation ability.

[0057] Please combine Figure 5 Similarly, when the second clamping member 133 is engaged with the tooth groove 111a, it abuts against the support surface 111c and fits with the support surface 111c, and the second clamping member 133 is gap-matched with the bottom of the tooth groove 111a.

[0058] During long-term use, as the second clamping member 133 is constantly engaged with and separated from the tooth grooves 111 a, the bottom of the second clamping member 133 is easily worn, resulting in a reduction in the actual size of the second clamping member 133 in the vertical direction.

[0059] At this time, if the depth of the second clamping member 133 inserted into the tooth groove 111a remains unchanged, there will be a gap between the second clamping member 133 and the supporting surface 111c of the tooth groove 111a. The supporting surface 111c cannot support the second clamping member 133, causing the entire second climbing assembly 130 including the second clamping member 133 to sink to a certain height, thereby affecting the climbing process of the first climbing assembly 120.

[0060] To this end, the support surface 111c is tilted and the second clamping member 133 is matched with the bottom clearance of the tooth groove 111a, thereby allowing the second clamping driving member 132 to drive the second clamping member 133 to be more deeply engaged in the tooth groove 111a until the second clamping member 133 abuts against the support surface 111c, while the height of the second clamping member 133 remains unchanged.

[0061] Furthermore, the second climbing assembly 130 also includes a second fixing member 134 , and the second fixing member 134 is fixedly connected to the second climbing member 131 .

[0062] The second clamping driving member 132 is fixedly disposed on the second fixing member 134 , and is connected to the second climbing member 131 via the second fixing member 134 .

[0063] In addition, the second clamping member 133 is slidably disposed on the second fixing member 134. The supporting force applied by the supporting member 111 to the second clamping member 133 is transmitted to the second climbing member 131 via the second fixing member 134, so as to prevent the second clamping driving member 132 from being damaged by tangential pressure.

[0064] Specifically, the climbing drive assembly 140 includes a climbing drive member 141. One end of the climbing drive member 141 along its driving direction is fixedly arranged on one of the first climbing member 121 and the second climbing member 131, and the other end of the climbing drive member 141 along its driving direction is a driving end, and is connected to the other of the first climbing member 121 and the second climbing member 131, and the driving direction of the climbing drive member 141 is consistent with the arrangement direction of the tooth grooves 111a, that is, the vertical direction.

[0065] Optionally, the climbing driving member 141 is fixedly disposed on the second climbing member 131 , and a driving end of the climbing driving member 141 is connected to the first climbing member 121 .

[0066] In some specific embodiments, the climbing driving member 141 is a climbing cylinder, the piston rod of which is vertically telescopic and connected to the first climbing member 121 .

[0067] In the process of lifting the raw material 10 upward, when the piston rod of the climbing cylinder extends, the first climbing member 121 moves away from the second climbing member 131. When the piston rod of the climbing cylinder retracts, the second climbing member 131 approaches the first climbing member 121.

[0068] Furthermore, the climbing drive assembly 140 also includes a height limiting member 142 , a first positioning member 143 , a second positioning member 144 and a limiting member 145 .

[0069] The height limiting member 142 is fixedly arranged on the bottom surface of the first climbing member 121, and is used to limit the retraction distance of the climbing cylinder (i.e., the climbing driving member 141). When the piston rod of the climbing cylinder retracts, the second climbing member 131 approaches the first climbing member 121 until the second climbing member 131 abuts against the height limiting member 142. At this time, the distance between the first climbing member 121 and the second climbing member 131 reaches the minimum.

[0070] In contrast, the first positioning member 143, the second positioning member 144 and the limiting member 145 are used to limit the extension distance of the climbing cylinder.

[0071] The first positioning member 143 is fixedly arranged on the side of the first climbing member 121, and the second positioning member 144 is fixedly arranged on the side of the second climbing member 131. The limiting member 145 is arranged in an annular shape and is sleeved on the first positioning member 143 and the second positioning member 144. The limiting member 145 always abuts against the first positioning member 143 under the action of its own gravity, and the second positioning member 144 can move up and down inside the limiting member 145.

[0072] When the piston rod of the climbing cylinder extends, the first climbing member 121 moves away from the second climbing member 131 until the second positioning member 144 abuts against the inner wall bottom surface of the limiting member 145. At this time, the distance between the first climbing member 121 and the second climbing member 131 reaches the maximum.

[0073] The height limiting member 142, the first positioning member 143, the second positioning member 144 and the position limiting member 145 are provided, so that the stroke of the climbing cylinder can be precisely controlled in a simple manner and more stably. In contrast, although linear drive elements such as electric cylinders can also achieve precise control, they need to be equipped with a controller, which increases the cost and has relatively low stability.

[0074] Furthermore, the climbing drive assembly 140 further includes a protection block 146. The protection block 146 is located outside the limiting member 145 and is fixedly connected to the first climbing member 121 to prevent debris such as iron filings from entering the inside of the limiting member 145.

[0075] Furthermore, the climbing mechanism 100 further includes an anti-fool column 150. The anti-fool column 150 is fixedly arranged on the top surface of the first climbing member 121, and is used to limit the height of the first climbing member 121 to rise.

[0076] For example, during the installation and commissioning of the processing device, when the first climbing member 121 rises to the anti-fool column 150 and abuts against other components of the processing device, the first climbing member 121 cannot move further upward, thereby avoiding pressure damage to precision parts such as the lifting member 125 caused by misoperation.

[0077] When the climbing mechanism 100 is in the initial state, the first clamping member 123 and the second clamping member 133 are respectively clamped into the corresponding No. 1 tooth groove 111a. After the raw material 10 is manually inserted into the groove at the top of the top material member 125, the top of the raw material 10 is slightly higher than the surface of the processing device, and the top end surface of the raw material 10 is milled flat by the CNC tool.

[0078] After that, the first clamping driving member 122 drives the first clamping member 123 to disengage from the corresponding No. 1 tooth groove 111a. The climbing driving member 141 drives the first climbing member 121 away from the second climbing member 131 until the second positioning member 144 abuts against the inner wall bottom surface of the limiting member 145, thereby lifting the raw material 10 upward to a fixed height through the lifting member 125. At this time, the first clamping member 123 is aligned with the corresponding No. 2 tooth groove 111a, and is clamped into the corresponding No. 2 tooth groove 111a under the drive of the first clamping driving member 122.

[0079] The second clamping driving member 132 drives the second clamping member 133 to disengage from the corresponding No. 1 tooth groove 111a, and the climbing driving member 141 drives the second climbing member 131 to approach the first climbing member until the second climbing member 131 abuts against the height limiting member 142. At this time, the second clamping member 133 is aligned with the corresponding No. 2 tooth groove 111a, and is clamped into the corresponding No. 2 tooth groove 111a under the drive of the second clamping driving member 132, completing the first automatic lifting action.

[0080] After the portion of the raw material 10 exposed on the surface of the processing device is formed into a small metal piece 20 through CNC processing, the above steps are repeated to lift the raw material 10 upward to a fixed height again until the entire raw material 10 is processed.

[0081] In summary, the push / pull actions of the first clamping member 123, the second clamping member 133, the first climbing member 121, and the second climbing member 131 in the above-mentioned climbing mechanism 100 are all driven by the electromagnetic valve automatic control cylinder, and the action of the first clamping member 123 engaging or separating with the tooth groove 111a, and the action of the second clamping member 133 engaging or separating with the tooth groove 111a are all performed before and after the push / pull action of the second climbing member 131, without interfering with each other. Thus, the first climbing component 120 and the second climbing component 130 can automatically climb upward in cooperation with the support member 111, ensure smooth operation, realize accurate lifting of the raw material 10, help improve processing accuracy, ensure the molding quality of the processed metal small part 20, and simple and convenient maintenance. After each group of raw materials 10 is processed, it can automatically return to the initial state (the opposite of the action process during lifting).

[0082] Example 2 See also Figure 1 This embodiment provides a processing device, specifically an automatic ascending feeding and automatic taking processing device, which is used to process a rod-shaped raw material 10 into a small metal piece 20 (see Figure 7 ). The processing device includes a support 200, a clamping and fixing mechanism 300 and the above-mentioned climbing mechanism 100.

[0083] The clamping and fixing mechanism 300 and the climbing mechanism 100 are both arranged on the support 200, and the clamping and fixing mechanism 300 is located above the climbing mechanism 100. When the climbing mechanism 100 lifts the raw material 10 upward to a fixed height, the clamping and fixing mechanism 300 clamps and fixes the raw material 10 so that the CNC tool can process the raw material 10.

[0084] Specifically, the support 200 is composed of a bottom template 210 , a column 220 and an upper template 230 .

[0085] The bottom template 210 and the upper template 230 are both arranged horizontally, and the column 220 is arranged vertically. The bottom template 210 is used to be fixedly connected to the CNC machine tool, the bottom end of the column 220 is fixedly connected to the bottom template 210, and the top end of the column 220 is fixedly connected to the upper template 230.

[0086] In addition, the support member 111 in the above-mentioned climbing mechanism 100 is fixedly arranged on the bottom template 210 , the bottom end of the guide column 112 in the climbing mechanism 100 is fixedly connected to the bottom template 210 , and the top end of the guide column 112 is fixedly connected to the upper template 230 .

[0087] Please also read Figure 6 and Figure 7 Specifically, the clamping and fixing mechanism 300 includes a mounting assembly 310, a clamping assembly 320 and a clamping drive assembly 330. The clamping assembly 320 and part of the clamping drive assembly 330 are mounted on the mounting assembly 310, and the clamping assembly 320 clamps and fixes the raw material 10 under the drive of the clamping drive assembly 330.

[0088] Specifically, the mounting assembly 310 includes a first mounting member 311 and a second mounting member 312. The first mounting member 311 is fixedly connected to the upper template 230, and the second mounting member 312 is fixedly connected to the first mounting member 311.

[0089] In some specific embodiments, the first mounting member 311 is a horizontally arranged integrated plate, which is bolted and fixed to the top surface of the upper template 230. The second mounting member 312 is a slide block, which is bolted and fixed to the top surface of the integrated plate.

[0090] Specifically, the clamping assembly 320 includes a raw material positioning member 321 , a first sliding member 322 and a clamping member 323 .

[0091] The raw material positioning member 321 is fixedly disposed on the first mounting member 311 and is located on one side of the raw material 10 .

[0092] The first sliding member 322 is slidably disposed on the second mounting member 312 along the horizontal direction and is located at the other side of the raw material 10 . The first sliding member 322 is driven by the clamping driving assembly 330 to approach or move away from the raw material positioning member 321 .

[0093] The clamping member 323 is connected to the first sliding member 322 , and moves with the first sliding member 322 toward the raw material positioning member 321 to clamp the raw material 10 , or moves with the first sliding member 322 in a direction away from the raw material positioning member 321 to release the raw material 10 .

[0094] Furthermore, a vertical connecting pin 322a is installed on the top of the first sliding member 322. Correspondingly, a through hole is provided on the clamping member 323, and the through hole is sleeved on the connecting pin 322a, so that the clamping member 323 and the first sliding member 322 are pin-connected.

[0095] On the one hand, the first sliding member 322 hooks the inner wall of the through hole through the connecting pin 322a, and can drive the clamping member 323 to move. On the other hand, the clamping member 323 can rotate slightly around the connecting pin 322a relative to the first sliding member 322, and has a swing function. When the surface of the raw material 10 facing the clamping member 323 and the surface of the clamping member 323 facing the raw material 10 are not parallel to each other, the clamping member 323 can adaptively swing a certain angle until the surface of the clamping member 323 is parallel to and close to the surface of the raw material 10, with a high fault tolerance rate, avoiding the inability to effectively clamp due to the unevenness of the raw material 10.

[0096] Specifically, the clamping driving assembly 330 includes a clamping driving member 331 and a second sliding member 332 .

[0097] The clamping driving member 331 is fixedly mounted on the upper template 230 , and a driving end of the clamping driving member 331 is connected to the second sliding member 332 .

[0098] The second sliding member 332 is slidably disposed on the second mounting member 312 along the vertical direction, and is in oblique contact with a side of the first sliding member 322 facing away from the raw material positioning member 321 .

[0099] When in use, the clamping driving member 331 drives the second sliding member 332 to slide in the vertical direction and abut against the first sliding member 322. The pressure applied by the second sliding member 332 to the first sliding member 322 is in the normal direction of the inclined surface, and the component force of the pressure in the horizontal direction drives the first sliding member 322 to slide toward the raw material positioning member 321, thereby driving the clamping member 323 to move until the raw material 10 is clamped.

[0100] It should be noted that in some specific embodiments, the raw material 10 is made of stainless steel. When the raw material 10 is processed into a small metal part 20, the cutting force is greater than that of a general aluminum part, and the clamping force requirement is higher. Since the contact surface between the second sliding member 332 and the first sliding member 322 is an inclined surface, when the driving force output by the clamping driving member 331 is constant, the processing operator can obtain a greater clamping force by adjusting the inclination angle of the inclined surface to ensure effective clamping of the raw material 10.

[0101] The principle is that the pressure applied by the second sliding member 332 to the first sliding member 322 is along the normal direction of the inclined surface. The component of the pressure along the horizontal direction is equal to the clamping force applied by the clamping member 323 to the raw material 10, and the component of the pressure along the vertical direction is equal to the component of the reaction force applied by the first sliding member 322 to the second sliding member 332 along the vertical direction, and is offset by the driving force output by the clamping driving member 331. Therefore, the smaller the angle α between the inclined surface and the vertical direction, the larger the angle β between the normal direction of the inclined surface and the vertical direction, and the larger the ratio tanβ of the clamping force to the driving force. Among them, β=π / 2-α.

[0102] In some specific embodiments, the clamping driving member 331 is a cylinder. The cylinder is fixedly mounted on the bottom surface of the upper template 230 by screws, and a cylinder pad 333 is provided between the cylinder body of the cylinder and the bottom surface of the upper template 230. In addition, the piston rod of the cylinder is transmission-connected to the second sliding member 332 through a cylinder connector 334.

[0103] In some specific embodiments, the normal direction of the inclined surface of the first sliding member 322 is inclined upward. When the clamping driving member 331 drives the second sliding member 332 to descend, the second sliding member 332 abuts against the first sliding member 322 and drives the first sliding member 322 to slide toward the raw material positioning member 321.

[0104] In some specific embodiments, the second sliding member 332 is a double-beveled sliding member. Accordingly, the clamping assemblies 320 are arranged in pairs on both sides of the second sliding member 332. One clamping drive assembly 330 drives two clamping assemblies 320 at the same time to clamp and fix the two raw materials 10.

[0105] At this time, the number of the clamping drive components 330 is the same as the number of the second mounting members 312, and is equal to half the number of the clamping components 320. When there are multiple clamping drive components 330, there are also multiple second mounting members 312, and the multiple second mounting members 312 are all fixed on the first mounting member 311.

[0106] Optionally, the number of the clamping drive components 330 and the number of the second mounting components 312 are both 8, and the number of the clamping components 320 is 16, which can clamp and fix 16 raw materials 10.

[0107] Furthermore, a spring hole is provided on one side of the first sliding member 322 facing the raw material positioning member 321, and a spring 322b is provided in the spring hole. The spring 322b is a compression spring and is provided along the sliding direction of the first sliding member 322. One end of the spring 322b abuts against the first sliding member 322, and the other end of the spring 322b abuts against the second mounting member 312.

[0108] When the clamping driving member 331 drives the second sliding member 332 to rise, the second sliding member 332 stops actively applying pressure to the first sliding member 322. The first sliding member 322 slides in a direction away from the raw material positioning member 321 driven by the spring 322b, releasing the raw material 10 so that the climbing mechanism 100 lifts the raw material 10 upward.

[0109] Furthermore, a protective cover 312 a is installed on the top of the second mounting member 312 to prevent debris such as iron filings from entering the interior of the second mounting member 312 .

[0110] Please also read Figure 1 and Figure 8 Furthermore, the above-mentioned processing device also includes a material taking mechanism 400.

[0111] After the CNC cutter processes the part of the raw material 10 exposed on the surface of the processing device into the small metal piece 20, the small metal piece 20 is not disconnected from the remaining raw material 10, but connected through the connecting portion 30, and the thickness of the connecting portion 30 is generally 0.2 mm. At this time, the material taking mechanism 400 can twist the small metal piece 20 off the connecting portion 30 and take the small metal piece 20 away.

[0112] Specifically, the material picking mechanism 400 includes a rotating member 410 and a material picking member 420 .

[0113] The rotating member 410 can rotate at high speed when driven by other power devices.

[0114] The material taking member 420 is vertically arranged, the top of the material taking member 420 is fixedly connected to the rotating member 410, and the bottom of the material taking member 420 is provided with a material taking slot 421 for the small metal piece 20 to be embedded.

[0115] When in use, the material taking member 420 is aligned with the processed small metal piece 20, and the material taking member 420 is lowered until the small metal piece 20 is embedded in the material taking slot 421. At this time, the rotating member 410 drives the material taking member 420 to rotate, and the small metal piece 20 can be twisted off from the connecting portion 30.

[0116] After the material taking member 420 twists off the small metal piece 20 from the material connecting portion 30, it continues to rotate at a high speed. The small metal piece 20 is pressed against the inner wall of the material taking slot 421 due to centrifugal action, and the small metal piece 20 is kept in the material taking slot 421 by friction and does not fall, so that the material taking mechanism 400 can transfer the small metal piece 20.

[0117] In some specific embodiments, the rotating member 410 is a tool handle, which is installed on the CNC tool turret and moves and rotates with the CNC spindle. The material taking member 420 is cylindrical, and the material taking slot 421 is a waist-shaped slot.

[0118] Please refer again Figure 1Furthermore, the processing device also includes a material storage mechanism 500.

[0119] The material storage mechanism 500 is fixedly mounted on the upper template 230 and is located on one side of the support 200. The material storage mechanism 500 has material storage slots 510, and the number of the material storage slots 510 is equal to the number of raw materials 10 clamped by the processing device, and each material storage slot 510 corresponds to one raw material 10.

[0120] After the material taking mechanism 400 takes down the small metal piece 20, the small metal piece 20 is transferred to the corresponding material storage tank 510. The CNC spindle stops rotating, and the small metal piece 20 is no longer subjected to the centrifugal effect, and thus falls into the corresponding material storage tank 510.

[0121] The storage trough 510 is matched with the raw material 10. When a plurality of raw materials 10 are processed at the same time, the small metal pieces 20 processed from each raw material 10 are stored separately, thereby achieving the traceability of the small metal pieces 20 during the processing and ensuring the quality.

[0122] When using the processing device, multiple raw materials 10 are manually inserted from the top of the processing device into the corresponding material ejection member 125. Each clamping driving member 331 drives the second sliding member 332 to slide downward, and the second sliding member 332 drives the first sliding member 322 to slide toward the raw material positioning member 321. The clamping member 323 moves with the second sliding member 332, and cooperates with the raw material positioning member 321 to clamp each raw material 10. At this time, the top of the raw material 10 is slightly higher than the surface of the processing device, and the top end surface of the raw material 10 is milled flat by the CNC tool.

[0123] Subsequently, each clamping driving member 331 drives the second sliding member 332 to slide upward. The second sliding member 332 slides in a direction away from the raw material positioning member 321 under the elastic force of the spring 322b, and the clamping member 323 moves with the second sliding member 332 to release the raw material 10. On this basis, the climbing mechanism 100 simultaneously lifts each raw material 10 upward to a fixed height.

[0124] The clamping and positioning mechanism clamps and fixes each raw material 10 again, and the CNC starts to process the small metal parts 20. After the processing is completed, the material taking mechanism 400 takes each small metal part 20 in turn and automatically stores it in the material storage mechanism 500.

[0125] The above-mentioned process of pushing material - clamping - processing - taking material is repeated until the whole raw material 10 is processed.

[0126] In short, the processing device is easy to operate. The operator only needs to clamp the raw material 10 and press the CNC start button. Each time the raw material 10 is switched, the continuous automatic production can be carried out for about 11 hours, reducing the number of operators by about 60%. In addition to the manual switching of the raw material 10, the automatic production can be carried out 24 hours a day, and the production efficiency is improved by about 30%. At the same time, it can also avoid product defects caused by human factors, and the quality is improved by about 5%.

[0127] In the above-mentioned processing device, the clamping and fixing mechanism 300 uses an oil cylinder as a driving source, and simultaneously drives the first sliding member 322 and the clamping member 323 on both sides through a double-bevel slider, which can effectively position and clamp the raw material 10. The climbing mechanism 100 can realize vector climbing, and each climbing can accurately position and fix. The material picking member 420 in the material picking mechanism 400 is a cylindrical material processed after end face grooving, which can automatically pick up and place the processed small metal parts 20, with a simple structure and very low cost. Through the cooperation of the above-mentioned mechanisms, except for the manual first clamping of the raw material 10, fully automated production is realized, with good stability, significantly improved production efficiency, and saved about 60% of the operator's manpower. At the same time, the quality of the small metal parts 20 is also improved.
