Description

Technical Field

[0001] The present invention relates to the field of treadmill cutting, in particular to a frame laser cutting device for treadmill production. Background Art

[0002] Laser cutting is a process that uses a high-power density laser beam to irradiate the material to be cut, causing the material to quickly heat to the vaporization temperature, evaporate to form holes, and continuously form very narrow slits as the beam moves, thus completing the cutting. However, when cutting the plate, it is necessary to maintain a certain distance between the cutting component and the plate. However, when cutting the treadmill frame, especially when cutting special-shaped frames, since the frame is not flat, the problem of metal droplets splashing will occur during the cutting process, thereby affecting the cutting quality of the frame.

[0003] For example, the Chinese invention patent (application number: CN202410235422.0) discloses a "laser cutting device for frame plates for treadmill production". Its specification discloses: the laser cutting equipment uses a laser to emit a high-energy laser beam to cut metal parts. When cutting the plate, in order to ensure that the plate can be completely cut and maintain the flatness of the cut end surface, it is necessary to maintain the same distance between the laser and the plate surface. However, the plates required for assembling a treadmill are not all flat plates. They include U-shaped frame plates and conical plates. When cutting smaller U-shaped plates, the laser will cause some molten metal droplets to splash out during the cutting process. Due to the special structure of the U-shaped plate, it is easy for the metal droplets to spray toward the uncut side of the U-shaped plate, causing the metal droplets to adhere and cool on the side of the U-shaped plate, resulting in metal balls of different sizes appearing on the cut end surface of the U-shaped plate, seriously affecting the quality of the U-shaped plate after laser cutting. The above patent can prove the defects of the existing technology.

[0004] Therefore, we have made improvements to this and proposed a frame laser cutting device for treadmill production. Summary of the Invention

[0050] The frame laser cutting device for treadmill production provided by the present invention, through the provision of a third sleeve shaft and a discharge shaft, and in conjunction with the cleaning liquid transported through a connecting hose, achieves that during the cutting process, the cutting component is always at a suitable cutting distance from the outer side of the frame by extrusion, and the cleaning liquid can also be sprayed out through the provision of a discharge valve and a material trough, thereby cleaning the cut frame.

[0051] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0052] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein may be combined with each other.

[0053] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0054] Example 1, please refer to Figure 15 and Figure 16A frame laser cutting device for treadmill production, wherein the bottom plate 304 is symmetrically provided with a fourth sleeve shaft 314 extending downward, and the fourth sleeve shaft 314 is provided with an adjustment shaft 315 extending outward. The bottom of the adjustment shaft 315 is fixedly installed with a fourth spring 316, and the bottom of the fourth spring 316 is fixedly connected to the inner cavity of the fourth sleeve shaft 314.

[0055] The air pressure inside the fourth sleeve shaft 314 is changed by the transverse tube 317, and the fourth spring 316 is used to change the height of the adjustment shaft 315 under the action of the air pressure, thereby adjusting the height of the cutting assembly 4 and cutting different positions.

[0056] Please refer to Figure 13 、 Figure 14 、 Figure 15 and Figure 16 The outer wall of the bottle 308 is provided with a sealing ring 308, and the outer wall of the bottle 308 is provided with a sealing ring 308. The outer wall of the bottle 308 is provided with a sealing ring 308, and the outer wall of the bottle 308 is provided with a sealing ring 308. The outer wall of the bottle 308 is provided with a sealing ring 308, and the outer wall of the bottle 308 is provided with a sealing ring 308.

[0057] The three-pronged pipe 307 fixedly installed at the air outlet end of the air pump 306 is convenient for changing the air pressure inside the clamping component 2, the material box 305 and the fourth sleeve shaft 314, so that the sealing push plate 308 and the adjusting shaft 315 are pushed to move accordingly by the air pressure, thereby realizing the transportation of the cleaning liquid and the height adjustment of the cutting component 4. After the cleaning liquid is transported to the inside of the third sleeve shaft 310, the cleaning liquid can also be used as a limit. By changing the filling amount of the cleaning liquid, the extension length of the discharge shaft 311 is adjusted. Therefore, when in use, since the discharge shaft 311 is squeezed with the frame and the cleaning liquid is used as a limit, the cutting component 4 can always be spaced a corresponding distance from the frame. The third spring 303 is set to cooperate with the mounting plate 301 and the socket plate 302 to facilitate the socket plate 302 and the components installed on its top to move synchronously with the side of the irregular frame.

Specifically, the clamping assembly 2 includes a servo motor 201 arranged on the top of the mounting frame 1, the output end of the servo motor 201 is a square shaft, a main gear 202 is arranged below the servo motor 201, an extension shaft 220 is fixedly installed at the bottom of the main gear 202, and the extension shaft 220 extends through the mounting plate 301 to its bottom, the mounting plate 301 is sleeved with the extension shaft 220, and the center of the main gear 202 is fixedly mounted on the main gear 202. A square groove 221 is provided on the bottom of the mounting plate 301, and the main gear 202 is sleeved with the output end of the servo motor 201 through the square groove 221. A fixed sleeve 222 is fixedly installed on the bottom of the mounting plate 301, and the fixed sleeve 222 is sleeved with the extension shaft 220.

One side of the fixed sleeve 222 is connected to the three-pronged pipe 307, and the outer side of the fixed sleeve 222 is equipped with a pressure relief valve.

[0061] By changing the air pressure inside the fixed sleeve 222 through the three-pronged pipe 307, and cooperating with the pressure relief valve on the outside of the fixed sleeve 222 and the second spring 223 in its inner cavity, the position of the extension shaft 220 and the main gear 202 can be reciprocated by changing the air pressure.

[0062] Further, such as Figure 11 and Figure 12 As shown, a tooth arc plate 224 is spaced apart below the main gear 202, and a right-angle shaft 225 is symmetrically mounted on the outer side of the tooth arc plate 224, and the other end of the right-angle shaft 225 is fixedly connected to the upper surface of the mounting plate 301;

[0063] By adjusting the position of the main gear 202 to cooperate with the servo motor 201 and the tooth arc plate 224, the adjusting component 3 and the cutting component 4 are driven to rotate through the right-angle shaft 225 and the mounting plate 301 to achieve cutting processing on the bending part of the frame.

[0064] Further, such as Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, one side of the main gear 202 is meshed with a sub-gear 203. The thickness of the main gear 202 is three times that of the sub-gear 203. A bottom shaft 211 is fixedly installed at the center of the bottom of the sub-gear 203. A second sleeve shaft 212 is sleeved on the outer side of the bottom shaft 211. A first spring 213 is fixedly installed on the bottom of the bottom shaft 211, and the bottom of the first spring 213 is fixedly connected to the inner cavity of the second sleeve shaft 212.

The other end of the connecting pipe 214 is connected to the fixed sleeve 222. The connecting pipe 214 is a hose and has a control valve on the outer side.

[0065] Through the connecting pipe 214, the second sleeve shaft 212, the pressure relief valve on its outer side, and the first spring 213 installed in its inner cavity, it is convenient to change the position of the bottom shaft 211 by adjusting the air pressure, thereby changing the position of the secondary gear 203, so that the secondary gear 203 is engaged or disengaged with the main gear 202.

[0066] Further, such as Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 , a rotating shaft 204 is fixedly installed at the center of the top of the sub-gear 203, and the rotating shaft 204 extends through the mounting frame 1 to the top, and blocks 205 are symmetrically installed on the outside of the rotating shaft 204, and a spring piece 226 is embedded in the outside of the block 205. A first sleeve shaft 206 is provided on the outside of the two groups of blocks 205, and the inner cavity of the first sleeve shaft 206 is provided with a sleeve groove 207. The middle and lower parts of the upper sleeve groove 207 are square, and their sizes match those of the block 205. The two ends of the square groove are circular grooves, and the diameter of the circular groove is slightly larger than the diagonal length of the block 205. The middle and upper parts of the lower sleeve groove 207 are square, and their sizes match those of the block 205.

The inner cavity array of the first sleeve shaft 206 is equipped with a card block 208, and the card block 208 matches the spring piece 226.

[0067] When the secondary gear 203 rotates, it drives the rotating shaft 204 to rotate, and by adjusting the position of the secondary gear 203, the position of the rotating shaft 204 is changed, so that the rotating shaft 204 is engaged with a set of first sleeve shafts 206 through the spring piece 226 and the clamping block 208, thereby driving the first sleeve shafts 206 to rotate synchronously.

[0069] When the rotating shaft 204 drives the first sleeve shaft 206 to rotate, the gear ring plate 210 meshing with the first sleeve shaft 206 is driven to rotate via the transmission gear 209, thereby achieving angle adjustment.

[0070] Further, such as Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 The outer sides of the two groups of tooth ring plates 210 are fixedly installed with support shafts 215.

[0071] When the two sets of tooth ring plates 210 rotate, they can respectively drive the support shaft 215 fixedly connected to them to rotate, and then adjust the position of the transmission roller 216, so as to clamp and fix the frame, and cooperate with the discharge shaft 311 that is squeezed and contacted with the outside of the frame to increase the stability of the clamping, and through the set drive motor 218, the worm gear 217 and the worm 219 can also drive the transmission roller 216 to rotate, thereby realizing the transmission of the frame.

[0072] The use process of the frame laser cutting device for treadmill production provided by the present invention is as follows:

[0073] When in use, first take out the frame to be cut and place it on both sides of the mounting frame 1, then start the air pump 306, and continuously deliver gas to the interior of the fixed sleeve 222 through a set of three-pronged pipes 307 set at the outlet end of the air pump 306, thereby delivering gas to the interior of the second sleeve shaft 212 through the connecting pipe 214 connected to the side wall of the fixed sleeve 222. Since the interior of the second sleeve shaft 212 is in a high-pressure state when it is stationary, the bottom shaft 211 lifts the sub-gear 203 and thus lifts the rotating shaft 204. At this time, the rotating shaft 204 is sleeved with the rotating shaft 204 through the sleeve groove 207 opened in the first sleeve shaft 206. As the gas is continuously delivered, the bottom shaft 211 continuously moves upward under the action of the high pressure and lifts the rotating shaft 204 through the sub-gear 203. At this time, the blocks 205 symmetrically arranged on the outside of the rotating shaft 204 The block 205 at the top is always engaged with the first sleeve shaft 206, and the block 205 at the bottom is in continuous contact with the square groove 221 in the middle of the sleeve groove 207 when it is constantly moving. At this time, the spring pieces 226 arranged in the array on the outer side of the block 205 are constantly popped out and constantly contact the clamping block 208. At this time, the lower block 205 is clamped with the first sleeve shaft 206 sleeved on its outer side. On the contrary, the pressure is released through the pressure relief valve on the side wall of the second sleeve shaft 212, so that the sub-gear 203 and the rotating shaft 204 can be lowered under the action of pressure, so that the upper block 205 is clamped. At this time, the discharge shaft 311 installed on the side wall of the cutting assembly 4 is in contact with the outer side of the frame, and under the air pressure of the third sleeve shaft 310 and the connecting hose 309, the cutting assembly 4 always maintains a certain distance from the outer side of the frame.

[0074] At this time, the servo motor 201 is started, and the servo motor 201 rotates through the main gear 202 installed on its output end, and drives the rotating shaft 204 to rotate through the main gear 202 and the sub-gear 203 engaged therewith, thereby driving the corresponding support shaft 215 and the transmission roller 216 sleeved on the support shaft 215 to rotate through the first sleeve shaft 206 sleeved on the outer side of the rotating shaft 204 and the transmission gear 209, until the two sets of transmission rollers 216 clamp and fix the inside of the cutting frame;

[0075] After the clamping is completed, the drive motor 218 fixedly installed on the side wall of the support shaft 215 is started and cooperates with the worm 219 installed on its output end to drive the worm gear 217 engaged with it to rotate, thereby driving the transmission roller 216 to rotate, and then the frame to be inspected is driven to move through the transmission roller 216. As the frame continues to move, the above steps can be repeated to rotate one set of support shafts 215, thereby making the two sets of clamped support shafts 215 always clamp the frame to be cut;

[0076] When the frame moves, the cutting assembly 4 is started to cut the frame. During the cutting process, the air pump 306 can also be started. The air pump 306 transmits gas through a set of three-pronged pipes 307 installed at its outlet end, in conjunction with the transverse pipe 317 and the fourth sleeve shaft 314 that passes through both ends of the transverse pipe 317, and in conjunction with the pressure relief valve on the side wall of the fourth sleeve shaft 314. By adjusting the internal air pressure of the fourth sleeve shaft 314, the height of the adjustment shaft 315 sealed at the top thereof is changed, thereby changing the position of the cutting assembly 4 installed at the top thereof, thereby adjusting the cutting position until the cutting reaches the corner.

[0077] At this time, the pressure relief valve on the side wall of the fixed sleeve 222 is activated to release the pressure. At the same time, the second spring 223 installed in the inner cavity thereof pulls the extension shaft 220 and the main gear 202 downward and engages with the tooth arc plate 224. Then, the servo motor 201 and the main gear 202 drive the tooth arc plate 224 and the right-angle shaft 225 installed on the side wall thereof to rotate, and then, under the buffering of the fourth spring 316, it rotates along the corner of the cutting frame, thereby completing the cutting.

[0078] During the cutting process, the air pump 306 and a set of three-pronged pipes 307 set at its air outlet end can also be started to deliver gas to the interior of the material box 305, and under the action of pressure, the sealing push plate 308 is squeezed to push the cleaning liquid accumulated on its top, so that it is transported to the interior of the third sleeve shaft 310 through the connecting hose 309, and the cleaning liquid is sprayed out in conjunction with the discharge valve 313 and the material trough 312, so as to clean the cross section after cutting.
