Description

Technical Field

[0001] The utility model relates to the field of automated processing, in particular to processing equipment suitable for processing eccentric features of bar materials. Background Art

[0002] With the gradual increase in labor costs, production and processing automation is an inevitable trend. At present, the automation of processing modules has become more and more mature, such as general-purpose CNC machining centers and various special-purpose machine tools. In order to improve processing efficiency and adapt to the processing of complex parts, the application of multi-station processing equipment is becoming more and more extensive. For example, the Chinese invention patent with the authorization announcement number CN 115592474B submitted by the applicant discloses a multi-station processing equipment and a processing method, in which the multi-station processing equipment is provided with processing units at the processing stations, some of which are arranged radially and some of which are arranged axially. By rotating the fixture seat, the conversion between multiple stations can be realized to complete each processing process, which has the advantage of high production efficiency.

[0003] However, the above multi-station processing equipment does not take into account the situation where the product has eccentric features. The so-called eccentric features are features that deviate from the geometric center of the product. In the processing clamping state, the corresponding features will also deviate from the center of the fixture clamping.

[0004] When the processed parts have eccentric features that require radial cutting, the radial processing unit also needs to be set eccentrically when the above-mentioned multi-station processing setting is used for processing. The corresponding chip force of the radial processing unit during cutting will inevitably exert a bending moment on the rotating fixture seat, causing the rotating fixture seat to have a tendency to rotate around the rotation center. This rotation tendency will affect the reliability of the locking of the rotating fixture seat during processing to a certain extent, and further affect the positioning accuracy of each station, the cutting accuracy of each station product, and the product processing quality. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a processing device suitable for processing eccentric features of bar materials. By setting an eccentric fixture, the centering setting of the radial processing unit can be ensured in the form of part offset, thereby avoiding the formation of bending moment and ensuring the processing quality.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is as follows: a processing device suitable for processing eccentric features of bar materials, comprising a feeding module and a processing module;

[0007] The processing module comprises a processing machine base and a clamping assembly, and the processing machine base is provided with a plurality of stations, including a loading and unloading station and at least one processing station, and at least one of the processing stations is provided with a radial processing unit;

[0008] The clamping assembly comprises a rotating clamp seat, an eccentric clamp and a rotating driving member, wherein the eccentric clamp is arranged on the rotating clamp seat, and the eccentric clamp is provided with two clamps arranged opposite to each other, and a clamping interval is formed between the two clamps;

[0009] The rotating fixture seat is rotatably arranged on the processing machine seat, and the rotating driving member is used to drive the rotating fixture seat to rotate, thereby realizing the transfer of the eccentric fixture between various workstations;

[0010] The rotating fixture seat is provided with a fixture installation position, and the fixture installation position is provided with a mounting plane, and the mounting plane is arranged parallel to the rotation center line of the rotating fixture seat; the clamping directions of the two chucks are arranged perpendicular to the rotation center line of the rotating fixture seat, and are arranged inclined relative to the mounting plane at the same time;

[0011] The cutting end of the radial machining unit is arranged radially toward the rotation center line of the rotating fixture seat, and the cutting end of the radial machining unit is aligned with the clamping interval of the corresponding eccentric fixture.

[0012] During processing, the loading module works first, conveying the bar material to be processed to the loading and unloading station, and the eccentric clamp located at the loading and unloading station clamps the bar material to be processed. Then the rotary drive works, the rotary clamp seat rotates relative to the processing machine seat, and the eccentric clamp is transferred from the loading and unloading station to the processing station, and each processing station processes the bar material. Finally, the rotary drive continues to work, the rotary clamp seat rotates relative to the processing machine seat, and the eccentric clamp is transferred to the loading and unloading station for unloading operations.

[0013] Since the radial processing unit is centrally arranged and the eccentric fixture is inclined to one side, the central arrangement of the radial processing unit can be ensured in the form of part offset, thereby avoiding the formation of bending moment and ensuring the processing quality.

[0014] Preferably, the processing module further comprises a cutting assembly, which is located at the loading and unloading station; the cutting assembly comprises a bar cutting unit. The cutting assembly is used to cut the long bars into blanks of specific lengths one by one, in preparation for subsequent processing operations.

[0015] Preferably, the eccentric clamp is slidably arranged on the mounting plane, and the sliding direction is arranged perpendicular to the rotation center line of the rotating clamp seat;

[0016] The clamping assembly further comprises an eccentric adjustment assembly, which is arranged on the rotating clamp seat and is used to drive the eccentric clamp to slide relative to the rotating clamp seat.

[0017] The sliding setting of the eccentric clamp can drive the movement of the clamped bar accordingly. That is, on the basis of the unchanged position of the radial processing unit, the eccentricity of the corresponding processing feature can be adjusted. By adjusting the processing eccentricity, it can adapt to the processing of products with different eccentricity and improve the versatility of the processing equipment. In addition, when there are at least two features with different eccentricity on a single part that need to be processed, the adjustment processing can also be achieved by sliding the eccentric clamp.

In addition, the screw transmission mechanism can be used to adjust the eccentric clamp. At the same time, because the screw mechanism has a certain self-locking ability in the reverse direction, the position of the eccentric clamp after adjustment can be guaranteed to be stable.

[0020] Preferably, the number of the processing stations is at least two, and at least two of the processing stations are provided with radial processing units.

[0021] Preferably, the loading module comprises a feeding assembly, a lifting assembly and a feeding assembly, wherein the feeding assembly is used to automatically transport the raw materials to the lifting assembly one by one;

The bar receiving units are provided with bar receiving grooves. The bar receiving grooves of the various bar receiving units are horizontally aligned and together form a bar receiving interval.

[0023] The bar receiving unit has at least two positions. In the first position, the bar receiving unit corresponds to the feeding assembly. In the second position, the bar receiving unit corresponds to the feeding assembly and is aligned with the loading and unloading stations of the processing machine base. The second position is located above the first position. The lifting drive unit is used to drive each bar receiving unit to move synchronously and transfer between the first position and the second position.

[0024] The feeding assembly comprises a feeding jaw and a feeding driving member, and the feeding driving member is used to drive the feeding jaw to reciprocate along the extension direction of the bar receiving section.

[0025] During the loading operation, the feeding assembly transports the bar to the lifting assembly, the lifting assembly adjusts the height position of the bar, and finally gradually feeds it axially through the feeding assembly and transports it section by section to the processing module for unloading operation.

[0026] Since the reliable clamping method for square bars during processing is diagonal clamping, and the bar receiving unit adopts the bottom receiving positioning form of the bar receiving slot, when the specifications of the bars are different, the positioning deviation of the bars between the loading module and the processing module is different. In the process of lifting the bars, the lifting component can play a good vertical compensation role according to the specifications of the bars, offset the positioning deviation, and improve the positioning accuracy.

[0027] Preferably, the feeding assembly comprises a feeding conveyor belt, a bar positioning mold is provided on the feeding conveyor belt, and the feeding conveyor belt is used to drive the bar positioning mold to move.

[0028] Preferably, the lifting assembly includes a lifting drive and a lifting chain, and the rod receiving unit corresponds to the lifting chain one by one and is connected; the lifting drive is used to drive the lifting chain to work, and then drive the rod receiving unit to move up and down.

[0029] Preferably, the bar receiving unit comprises two receiving shafts, the two receiving shafts are inclined upward and distributed at an angle of 90°, a bar receiving groove is formed between the two receiving shafts, and rollers are respectively sleeved on the two receiving shafts.

[0030] When the bar is fed axially, the bar and the bar receiving unit roll relative to each other, which can reduce friction and vibration.

[0031] Preferably, it further comprises an adjustment component, and when the bar receiving unit is in the second position state, the adjustment component is aligned with the bar receiving section;

[0032] The adjustment assembly includes an adjustment push unit and an end positioning unit. In the horizontal direction, the bar receiving unit is located between the adjustment push unit and the end positioning unit, and the end positioning unit is arranged close to the processing module.

When the rod moves to a specific distance from the end of the positioning sensor, it is considered to be adjusted in place and the adjustment pushing unit stops working.

[0034] After the bar is lifted to the second position and before loading, the adjustment component works to axially position the bar, providing accuracy guarantee for the subsequent feeding operation of the feeding component and the clamping and unloading operation of the processing module, while reducing the waste of the bar. The setting of the feeding drive can adjust the position of the positioning sensor. When the adjustment operation is performed, the positioning sensor moves to align with the bar receiving section; after the adjustment operation is completed, the positioning sensor moves to be misaligned with the bar receiving section to leave space for the feeding of the bar.

[0054] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Example

[0055] like Figure 1 As shown, a processing device suitable for processing eccentric features of square bars includes a loading module 2 and a processing module 1.

[0056] like Figure 2-Figure 5As shown, the loading module 2 includes a feeding assembly 21, a lifting assembly 22 and a feeding assembly 23. The feeding assembly 21 includes a feeding conveyor belt 214. The feeding conveyor belt 214 is provided with a bar positioning mold 213. The feeding conveyor belt 214 is used to drive the bar positioning mold 213 to move. The feeding assembly 21 is used to automatically convey the raw materials one by one to the lifting assembly 22.

[0057] like Figure 2-Figure 5 As shown, specifically, the number of the feeding conveyor belts 214 is at least two, and each feeding conveyor belt 214 is arranged in parallel. The bar positioning molds 213 between each feeding conveyor belt 214 correspond to each other. In order to ensure the synchronization of the operation of each feeding conveyor belt 214, the feeding assembly 21 also includes a feeding drive 211 and a feeding transmission rod 212. The feeding drive 211 drives the feeding transmission rod 212 to rotate, and each of the feeding conveyor belts 214 and the feeding transmission rod 212 is driven by a belt.

[0058] Further, such as Figure 5 As shown, the feeding assembly 21 further includes an orientation detection unit 215, which is located on one side of the feeding conveyor belt 214 and is arranged toward the bar positioning mold 213. When the sides of the bar are different, the circumferential orientation of the bar can be detected and positioned by the orientation detection unit 215, thereby ensuring the accurate orientation of the bar during transportation.

[0059] like Figure 6 and Figure 7 As shown, the lifting assembly 22 includes a rod receiving unit 223 and a lifting drive unit. The number of the rod receiving units 223 is not less than two. The rod receiving units 223 are provided with rod receiving grooves. The rod receiving grooves of each rod receiving unit 223 are horizontally aligned and together form a rod receiving interval.

[0060] like Figure 6 and Figure 7 As shown, the bar receiving unit 223 has at least two position states: in the first position state, the bar receiving unit 223 corresponds to the feeding assembly 21, and in the second position state, the bar receiving unit 223 corresponds to the feeding assembly 23 and is aligned with the loading and unloading station 11 of the processing base 12; the second position state is located above the first position state, and the lifting drive unit is used to drive each bar receiving unit 223 to move synchronously and transfer between the first position state and the second position state.

[0061] Specifically, Figure 6 , Figure 7 and Fig.10As shown, the lifting assembly 22 includes a lifting drive and a lifting chain, and the bar receiving unit 223 corresponds to the lifting chain one by one and is connected; the lifting drive is used to drive the lifting chain to work, and then drive the bar receiving unit 223 to move up and down.

[0062] like Figure 6 , Figure 7 and Fig.10 As shown, specifically, the lifting drive component includes a lifting motor 221 and a lifting transmission rod 222, and the lifting motor 221 is used to drive the lifting transmission rod 222 to rotate; a plurality of lifting sprockets are fixedly arranged on the lifting transmission rod 222, and the lifting sprockets correspond to and mesh with the lifting chains one by one.

[0063] By adopting the chain transmission form, the transmission ratio and accuracy are more reliable. At the same time, multiple lifting chains are synchronously driven through the lifting transmission rod 222, which can effectively ensure the synchronization of the movement of each lifting chain.

[0064] Further, such as Fig.11 and Fig.12 As shown, the bar receiving unit 223 includes two receiving shafts 2231, which are inclined upward and distributed at an angle of 90°, and a bar receiving groove is formed between the two receiving shafts 2231. Rollers 2232 are respectively sleeved on the two receiving shafts 2231. When the bar is axially fed, the bar and the bar receiving unit 223 roll relative to each other, which can reduce friction and vibration.

[0065] like Figure 6 , Figure 7 and Fig.10 As shown, the feed assembly 23 includes a feed jaw 233 and a feed drive, and the feed drive is used to drive the feed jaw 233 to reciprocate along the extension direction of the bar receiving interval.

[0066] like Figure 6 , Figure 7 and Fig.10 As shown, specifically, the feed drive comprises a feed motor 231, a feed screw 232 and a feed slider, the feed motor 231 is used to drive the feed screw 232 to rotate, the feed slider is threadedly connected to the feed screw 232; the feed jaw 233 is arranged on the feed slider.

[0067] During the loading operation, the feeding assembly 21 conveys the bar material to the lifting assembly 22, the lifting assembly 22 adjusts the height position of the bar material, and finally gradually feeds the bar material axially through the feeding assembly 23, and conveys it section by section to the processing module 1 for unloading operation.

[0068] Since the reliable clamping method for square bars during processing is diagonal clamping, and the bar receiving unit 223 adopts the bottom receiving positioning form of the bar receiving groove, when the specifications of the bars are different, the positioning deviation of the bars between the loading module 2 and the processing module 1 is different. In the process of lifting the bars, the lifting component 22 can play a good vertical compensation role according to the specifications of the bars, offset the positioning deviation, and improve the positioning accuracy.

[0069] like Figure 7-Figure 9 As shown, further, it also includes an adjustment component. When the bar receiving unit 223 is in the second position state, the adjustment component is aligned with the bar receiving interval.

[0070] like Figure 7-Figure 9 As shown, the adjustment component includes an adjustment pushing unit 261 and an end positioning unit 262 . In the horizontal direction, the bar receiving unit 223 is located between the adjustment pushing unit 261 and the end positioning unit 262 , and the end positioning unit 262 is arranged close to the processing module 1 .

[0071] like Figure 7-Figure 9 As shown, the end positioning unit 262 includes a positioning sensor 261 and a feed drive 2621. The feed drive 2621 is used to drive the positioning sensor 261 to move in a vertical plane. The adjustment push unit 261 is used to drive the bar material to move along the extension direction of the bar material receiving section. When the bar material moves to a specific distance from the end of the positioning sensor 261, it is considered to be adjusted in place, and the adjustment push unit 261 stops working.

[0072] After the bar is lifted to the second position and before loading, the adjustment component works to axially position the bar, providing accuracy guarantee for the subsequent feeding operation of the feeding component 23 and the clamping and unloading operation of the processing module 1, while reducing the waste of the bar. The setting of the feeding drive can adjust the position of the positioning sensor 261. When the adjustment operation is performed, the positioning sensor 261 moves to align with the bar receiving interval. After the adjustment operation is completed, the positioning sensor 261 moves to be misaligned with the bar receiving interval, leaving space for the feeding of the bar.

[0073] like Figure 2 and Figure 3 As shown, the first bracket 24 and the second bracket 25 are also included, the first bracket 24 is located on one side of the second bracket 25, the feeding assembly 21 is arranged on the first bracket 24, and the lifting assembly 22, the feeding assembly 23 and the adjusting assembly are arranged on the second bracket 25. The discharge end of the feeding conveyor belt 214 corresponds to the second bracket 25, and the lifting assembly 22 is located on the side of the second bracket 25 facing the first bracket 24.

[0074] like Figure 13-Figure 15As shown, the processing module 1 includes a processing machine base 12 and a clamping assembly 16. The processing machine base 12 is provided with a plurality of workstations, including a loading and unloading station 11 and at least one processing station. At least one of the processing stations is provided with a radial processing unit 13, and at least one of the processing stations is provided with an axial processing unit 14.

[0075] like Fig.16 and Fig.17 As shown, the clamping assembly 16 includes a rotating clamp seat 162, an eccentric clamp 161 and a rotating drive member. The eccentric clamp 161 is arranged on the rotating clamp seat 162. The eccentric clamp 161 is provided with two oppositely arranged clamps 1613, and a clamping interval is formed between the two clamps 1613.

[0076] like Fig.16 and Fig.17 As shown, the rotating fixture seat 162 is rotatably arranged on the processing machine base 12, and the rotating driving member is used to drive the rotating fixture seat 162 to rotate, so as to realize the transfer of the eccentric fixture 161 between various workstations.

[0077] like Fig.18 As shown, the rotating clamp seat 162 is provided with a clamp installation position, and the clamp installation position is provided with a mounting plane 163, and the mounting plane 163 is arranged parallel to the rotation center line of the rotating clamp seat 162. The eccentric clamp 161 is located on the mounting plane 163, and the clamping direction of the two clamps 1613 is arranged perpendicular to the rotation center line of the rotating clamp seat 162, and at the same time, they are arranged at a 45° angle relative to the mounting plane 163. The clamp 1613 is provided with a V-shaped clamping groove, and the opening angle of the V-shaped clamping groove is 90°. The V-shaped clamping groove faces the clamping interval and is opposite to each other on the left and right.

[0078] The cutting end of the radial machining unit 13 is arranged radially toward the rotation center line of the rotating fixture seat 162 , and the cutting end of the radial machining unit 13 is aligned with the clamping section of the corresponding eccentric fixture 161 .

[0079] Specifically, the number of the processing stations is at least two, and at least two of the processing stations are provided with radial processing units 13 .

[0080] like Fig.17 As shown, specifically, the number of the clamp installation positions is at least two, and each clamp installation position is evenly distributed circumferentially around the rotation center line of the rotating clamp seat 162, and the eccentric clamps 161 correspond to the clamp installation positions one by one.

[0081] During processing, the loading module 2 works first, and the bar material 3 to be processed is transported to the loading and unloading station 11, and the eccentric clamp 161 located at the loading and unloading station 11 clamps the bar material to be processed. Then the rotary drive member works, the rotary clamp seat 162 rotates relative to the processing machine seat 12, and the eccentric clamp 161 is transferred from the loading and unloading station 11 to the processing station, and each processing station processes the bar material. Finally, the rotary drive member continues to work, the rotary clamp seat 162 rotates relative to the processing machine seat 12, and the eccentric clamp 161 is transferred to the loading and unloading station 11 to perform the unloading operation.

[0082] Since the radial processing unit 13 is centrally arranged and the eccentric fixture 161 is inclined to one side, the central arrangement of the radial processing unit 13 can be ensured in the form of part offset, thereby avoiding the formation of bending moment and ensuring the processing quality.

[0083] Since the opening angle of the V-shaped clamping groove is 90°, and the clamping direction of the two chucks 1613 is set perpendicular to the rotation center line of the rotating fixture seat 162, and at the same time is set at a 45° angle relative to the mounting plane 163, after the bar is reliably clamped, a group of side surfaces will be set parallel to the mounting plane 163, and this group of side surfaces is also set perpendicular to the cutting end of the radial machining unit 13, which is convenient for cutting features perpendicular to the corresponding plane.

[0084] like Fig.14 As shown, further, the processing module 1 further includes a cutting assembly 15, which is located at the loading and unloading station 11 and includes a bar cutting unit. The cutting assembly 15 is used to cut the long bars into blanks of a specific length one by one to prepare for subsequent processing operations.

[0085] Specifically, the eccentric clamp 161 is slidably disposed on the mounting plane 163 , and the sliding direction is perpendicular to the rotation center line of the rotating clamp seat 162 .

[0086] like Fig.19 As shown, the clamping assembly 16 further includes an eccentric adjustment assembly, which is disposed on the rotating clamp seat 162 and is used to drive the eccentric clamp 161 to slide relative to the rotating clamp seat 162 .

[0087] By sliding the eccentric clamp 161, the movement of the clamped bar can be driven accordingly. That is, on the basis of the unchanged position of the radial processing unit 13, the eccentricity of the corresponding processing feature can be adjusted. By adjusting the processing eccentricity, it is possible to adapt to the processing of products with different eccentricity, thereby improving the versatility of the processing equipment. In addition, when at least two features with different eccentricity need to be processed on a single part, the adjustment processing can also be achieved by sliding the eccentric clamp 161.

[0088] like Fig.19 As shown, specifically, the eccentric clamp 161 also includes an adjustment block 1611, and the adjustment block 1611 is provided with an intermediate mounting bevel 1612, and the intermediate mounting bevel 1612 is arranged parallel to the rotation center line of the rotating clamp seat 162 and inclined relative to the mounting plane 163; the chuck 1613 is slidably arranged on the intermediate mounting bevel 1612.

[0089] The eccentric adjustment assembly includes an adjustment drive unit and a screw transmission unit. The adjustment drive unit is connected to the eccentric clamp 161 through the screw transmission unit and drives the eccentric clamp 161 to slide and adjust.

[0090] By setting the adjustment block 1611 and the middle installation inclined surface 1612, the inclined eccentric setting of the eccentric clamp 161 is realized, and the installation and motion control of the clamp 1613 are more convenient. In addition, the screw transmission mechanism can realize the adjustment of the eccentric clamp 161, and because the screw mechanism has a certain self-locking ability in the reverse direction, the position of the eccentric clamp 161 after adjustment can be ensured to be stable.

[0091] A processing method suitable for processing eccentric features of square bars adopts the processing equipment as described above.

[0092] At least the following steps are included:

[0093] S1. Loading: Put the bar into the bar positioning mold 213 of the feeding conveyor belt 214. The loading module 2 works to sequentially convey the bar to be processed to the bar receiving unit 223 of the lifting assembly 22, and the lifting assembly 22 is transferred from the first position to the second position. The adjustment assembly adjusts and positions the bar axially, and finally the feeding assembly 23 works to convey the bar to the loading and unloading station 11, and the eccentric clamp 161 located at the loading and unloading station 11 clamps the bar to be processed.

[0094] S2. Transfer: The cutting assembly 15 works to cut the bar into a specific length. The rotary drive member works, the rotary fixture seat 162 rotates relative to the processing machine seat 12, and the eccentric fixture 161 is transferred from the loading and unloading station 11 to the processing station.

[0095] S3. Processing: The bar is processed, the rotary drive continues to work, the rotary fixture seat 162 rotates relative to the processing machine seat 12, and the eccentric fixture 161 is transferred to each processing station in turn until all processing operations are completed. When the eccentric fixture 161 is transferred to the processing station with the radial processing unit 13, the eccentric adjustment component works to adjust the eccentric distance, and the corresponding radial processing unit 13 processes the bar.

[0096] S4. Unloading: The rotary drive component continues to work, the rotary fixture seat 162 rotates relative to the processing machine seat 12, and the eccentric fixture 161 is transferred to the loading and unloading station 11 to perform unloading operations.

[0097] In short, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
