Description

Technical Field

[0001] This utility model belongs to the field of polishing equipment technology, and specifically relates to an anti-bounce mechanism and a wrench polishing machine. Background Technology

[0002] After stamping, hardware accessories often have defects such as burrs and protrusions on their surface, such as wrenches. These defects not only affect the appearance quality of the product, but also reduce its performance and lifespan. Therefore, polishing is necessary. Polished wrenches have a smoother surface and are more wear-resistant, which can extend their service life.

[0003] During the polishing process, the wrench needs to be in direct contact with the polishing equipment. The wrench surface is polished using tools such as polishing wheels or polishing belts. However, in actual polishing operations, the wrench is usually simply clamped in a fixture for polishing. This traditional clamping method has certain problems. Because the polishing equipment applies a large force to the wrench during the polishing process, the wrench is prone to vibration. Once the wrench vibrates during polishing, it will directly cause uneven polishing of the wrench surface. In addition, if it is in a state of vibration for a long time, the fixture may gradually loosen. Once the fixture loosens, the stability of polishing will be greatly reduced, and the accuracy and consistency of the polishing process cannot be guaranteed, thus affecting the overall quality of the product. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing an anti-bounce mechanism and a wrench polishing machine. The technical problem to be solved by this utility model is: how to ensure the stability of the wrench during the polishing process.

[0005] The above-mentioned technical objective of this utility model can be achieved through the following technical solution: an anti-bounce mechanism, including a throwing rod, a slidably arranged support frame, a driving component, and a locking assembly. The driving component, the support frame, and the locking assembly are all connected to the throwing rod. The throwing rod is used to support one end of a wrench, and the support frame is used to support the other end of the wrench. The driving component is used to drive the support frame to slide so that it moves closer to or away from the throwing rod. The locking assembly is used to press the wrench. When the driving component drives the support frame to slide and cooperates with the throwing rod to clamp the wrench, the locking assembly presses both ends of the wrench onto the throwing rod and the support frame respectively.

[0006] In the aforementioned anti-bounce mechanism, the anti-bounce mechanism further includes a sliding linkage component. The locking assembly includes a rotatably mounted swing bracket, a clamping hook, and a return spring. The clamping hook is mounted on the swing bracket. When the driving component drives the support frame to slide and cooperates with the throwing rod to clamp the wrench, the linkage component drives the swing bracket to rotate, causing the clamping hook to press against the wrench. The return spring is used to rotate the swing bracket back to its original position and drive the clamping hook away from the wrench.

[0007] In the aforementioned anti-bounce mechanism, the swing bracket has a linkage hole with an arc-shaped inner wall and a frustum-shaped linkage component. When the linkage component is inserted into the linkage hole, the outer wall of the linkage component can fit against the inner wall of the linkage hole. The swing bracket rotates and drives the clamping hook to press against the wrench. When the linkage component disengages from the linkage hole, the return spring causes the swing bracket to rotate and reset, and drives the clamping hook away from the wrench.

[0008] In the aforementioned anti-bounce mechanism, the locking assembly includes a finger cylinder and two clamping rods. The output end of the finger cylinder is connected to the two clamping rods, and the finger cylinder is used to drive the two clamping rods to press against or away from the wrench.

[0009] In the aforementioned anti-bounce mechanism, the driving component includes a motor and a lead screw. The output end of the motor is connected to the lead screw. A clamping bracket is installed on the throwing rod. The support frame is slidably mounted on the clamping bracket. A movable frame is slidably mounted on the clamping bracket. The lead screw passes through the support frame and the two are threaded together. The lead screw passes through the movable frame and the two are threaded together. The linkage component is mounted on the movable frame.

[0010] In the aforementioned anti-bounce mechanism, the driving component includes a driving cylinder, the output end of which is connected to the linkage component, and the linkage component is connected to the support frame.

[0011] In the aforementioned anti-bounce mechanism, the driving component includes a second driving cylinder and a second return spring. The output end of the second driving cylinder is connected to the support frame, the support frame is connected to the linkage component, the linkage component is provided with a connecting rod, the connecting rod is provided with a limiting part, the connecting rod is movably inserted through a support plate fixedly connected to the throwing rod, and the second return spring is disposed between the limiting part and the support plate. The limiting part can cooperate with the support plate to compress the second return spring.

[0012] A wrench polishing machine includes an anti-jump mechanism, a rotary drive source, a polishing mechanism, and a feeding assembly, as described above. The rotary drive source drives the polishing bar to rotate, and causes the support frame to rotate the wrench around the polishing bar, thus cooperating with the polishing mechanism to polish the side of the wrench. The feeding assembly is used to detach the polished wrench from the polishing bar and the support frame.

[0013] In the aforementioned wrench polishing machine, the feeding assembly includes a feeding cylinder and a feeding component. The feeding cylinder is used to drive the feeding component to push the polished wrench away from the polishing rod and the support frame.

[0014] In the aforementioned wrench polishing machine, the feeding assembly includes a lifting cylinder, a clamping robot, and a linear drive module. The linear drive module is connected to the lifting cylinder and is used to drive the lifting cylinder to slide horizontally. The output end of the lifting cylinder is connected to the clamping robot and is used to drive the clamping robot to slide vertically. The clamping robot is used to clamp the wrench.

[0015] In summary, the beneficial effects of this utility model compared to the prior art are as follows:

[0016] The drive unit drives the support frame to slide and cooperates with the throwing rod to clamp the wrench. At the same time, the locking assembly presses both ends of the wrench onto the throwing rod and the support frame respectively, thereby ensuring the stability of the wrench during the polishing process and avoiding the impact on polishing accuracy due to wrench instability.

[0034] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0035] Example 1:

[0036] A type of anti-bounce mechanism, such as Figures 1 to 3As shown, it includes a throwing rod 2, a sliding support frame 3, a driving component 4, a sliding linkage component 5, and a material locking assembly 6.

[0037] The driving component 4, the support frame 3, and the material locking assembly 6 are all connected to the throwing rod 2. Specifically, a clamping bracket 9 is installed on the throwing rod 22, the support frame 3 is slidably connected to the clamping bracket 9, and the driving component 4 and the material locking assembly 6 are all connected to the clamping bracket 9.

[0038] The lever 2 is used to support one end of the wrench. Specifically, the lever 2 has a support step 12. One end of the wrench is fitted onto the lever 2, and the lower surface of the wrench abuts against the step surface of the support step 12. This not only enables the lever 2 to support the wrench, but also limits the wrench's position, effectively ensuring the stability of the wrench.

[0039] The support frame 3 is used to support the other end of the wrench. The lower surface of the wrench abuts against the upper surface of the support frame 3. In this embodiment, the upper surface of the support frame 3 has a tripod 13 for limiting the wrench. This not only enables the support frame 3 to support the wrench, but also effectively ensures the stability of the wrench by limiting the end of the wrench through the tripod 13.

[0040] It should be noted that the height of the throwing rod 2 and the support frame 3 can be adjusted according to actual needs. In this embodiment, the support frame 3 is assembled from two parts connected by bolts, which facilitates the height adjustment of the support frame 3.

[0041] The driving component 4 is used to drive the support frame 3 to slide closer to or further away from the throwing rod 2. The driving component 4 includes a driving cylinder 44. The output end of the driving cylinder 44 is connected to the linkage component 5. The linkage component 5 is connected to the support frame 3. That is, through the driving action of the driving cylinder 44, the linkage component 5 slides and drives the support frame 3 to slide.

[0042] The locking assembly 6 is used to tighten the wrench. Specifically, the locking assembly 6 includes a rotatable swing bracket 61, a clamping hook 62, and a return spring 63. The clamping hook 62 is mounted on the swing bracket 61. In this embodiment, the clamping hook 62 and the swing bracket 61 are connected by bolts to facilitate the adjustment of the height of the clamping hook 62 to accommodate wrenches of different sizes.

[0043] When the driving component 4 drives the support frame 3 to slide and cooperates with the throwing rod 2 to clamp the wrench, the locking assembly 6 presses both ends of the wrench onto the throwing rod 2 and the support frame 3 respectively. Specifically, when the driving component 4 drives the support frame 3 to slide and cooperates with the throwing rod 2 to clamp the wrench, the linkage component 5 drives the swing bracket 61 to rotate, so that the clamping hook 62 is pressed onto the wrench. The return spring 63 is used to rotate the swing bracket 61 to return to its original position and drive the clamping hook 62 away from the wrench.

[0044] It should be noted that before polishing, the swing bracket 61 rotates and drives the clamping hook 62 to press against the wrench, thereby ensuring the stability of the wrench during the polishing process. After the polishing is completed, the elastic restoring force of the return spring 63 causes the swing bracket 61 to rotate back and drive the clamping hook 62 away from the wrench, at which point the polished wrench can be easily removed.

[0045] It should be noted that, regarding how the linkage 5 drives the swing bracket 61 to rotate, specifically, the swing bracket 61 has a linkage hole 8, the inner wall of the linkage hole 8 is arc-shaped, and the linkage 5 is frustum-shaped. Alternatively, the linkage 5 can be conical. When the linkage 5 is inserted into the linkage hole 8, the outer wall of the linkage 5 can fit against the inner wall of the linkage hole 8. At this time, the force exerted by the linkage 5 on the inner wall of the linkage hole 8 causes the swing bracket 61 to rotate. The swing bracket 61 causes the return spring 63 to deform and causes the clamping hook 62 to press against the wrench. It should be noted that, due to the force exerted by the linkage 5 on the swing bracket 61 at this time, the swing bracket 61 cannot be rotated back to its original position by the elastic restoring force of the return spring 63, thereby locking the swing bracket 61 and the clamping hook 62. This ensures that the clamping hook 62 is always pressed against the wrench during the polishing process, thus ensuring the stability of the wrench. When the linkage 5 disengages from the linkage hole 8, the swing bracket 61 loses the force exerted by the linkage 5, and the elastic restoring force of the return spring 63 causes the swing bracket 61 to rotate back to its original position and drives the clamping hook 62 away from the wrench.

[0046] Driven by the cylinder 44, the linkage 5 slides and drives the support frame 3 to slide. As the support frame 3 slides and works with the throwing rod 2 to clamp the wrench, the linkage 5 inserts into the linkage hole 8. This causes the swing bracket 61 to rotate and cause the return spring 63 to deform and cause the clamping hook 62 to press against the wrench. Alternatively, when the support frame 3 slides away from the throwing rod 2, the linkage 5 disengages from the linkage hole 8, and the swing bracket 61 rotates back to its original position by the elastic restoring force of the return spring 63, causing the clamping hook 62 to move away from the wrench.

[0047] It should be noted that during polishing, the wrench is clamped by the support frame 3 in conjunction with the polishing rod 2, and the clamping hook 62 presses the wrench firmly onto the polishing rod 2 and the support frame 3. This ensures the stability of the wrench during the polishing process and avoids affecting the polishing accuracy due to the instability of the wrench.

[0048] Example 2:

[0049] The difference between Example 2 and Example 1 is that, as Figure 4As shown, the locking assembly 6 includes a finger cylinder 64 and two clamping rods 65. The output end of the finger cylinder 64 is connected to the two clamping rods 65. The two clamping rods 65 are both in the shape of a "7" and are arranged opposite to each other. The finger cylinder 64 is used to drive the two clamping rods 65 to press against the wrench or away from the wrench.

[0050] Specifically, the two clamping rods 65 can be driven by the finger cylinder 64 to move closer together and press them against the wrench, or the two clamping rods 65 can be driven by the finger cylinder 64 to move further away from the wrench. By using the two clamping rods 65 in a figure-7 shape to press the wrench, the stability of the wrench can be further improved. Moreover, driving the two clamping rods 65 with the finger cylinder 64 is more efficient, has a simpler structure, and is easier to manufacture.

[0051] Example 3:

[0052] The difference between Example 3 and Example 1 is that, as Figure 5 As shown, the locking assembly 6 includes a lever cylinder 66 and a pressure rod 67. The output end of the lever cylinder 66 is connected to the pressure rod 67, which is shaped like a "7". The lever cylinder 66 drives the pressure rod 67 to rotate so that it presses against the wrench, thereby tightening the wrench. When unloading, the lever cylinder 66 drives the pressure rod 67 to rotate away from the wrench so that the material can be unloaded normally.

[0053] Example 4:

[0054] The difference between Example 4 and Example 1 is that, as Figure 6 As shown, the material locking assembly 6 includes a rotary pressing cylinder 68. The output end of the rotary pressing cylinder 68 rotates and approaches the wrench until it presses against the wrench, thereby tightening the wrench. When unloading, the output end of the rotary pressing cylinder 68 can be moved away from the wrench. The rotary pressing cylinder 68 method is more efficient, has a simpler structure, and is easier to manufacture.

[0055] Example 5:

[0056] The difference between Example 5 and Example 1 is that, as Figure 7 As shown, the locking assembly 6 includes a linear drive source 69 and a pressure rod 610. The output end of the linear drive source 69 is connected to the pressure rod 610, which is shaped like a "7". The linear drive source 69 drives the pressure rod 610 to move horizontally, thereby moving the pressure rod 610 closer to and pressing it against the wrench or away from the wrench. The linear drive source 69 can be an electric cylinder. In this embodiment, during material feeding, the wrench is gripped by a gripper cylinder in the prior art, and then the gripper cylinder, gripper, and the gripped wrench are driven by the linear drive module in the prior art to move horizontally and vertically in sequence for material feeding.

[0057] Example 6:

[0058] The difference between Example 6 and Example 1 is that, as Figure 8 As shown, the driving component 4 includes a second driving cylinder 45 and a second return spring 46. The output end of the second driving cylinder 45 is connected to the support frame 3. The support frame 3 is connected to the linkage component 5. The linkage component 5 is provided with a connecting rod 48. The end of the connecting rod 48 is provided with a limiting part 47. The connecting rod 48 is movably inserted through the support plate 10 which is fixedly connected to the throwing rod 2. The support plate 10 is installed on the clamping bracket 9. The second return spring 46 is disposed between the limiting part 47 and the support plate 10. The limiting part 47 can cooperate with the support plate 10 to squeeze the second return spring 46.

[0059] Specifically, the support frame 3 is driven to slide away from the throwing rod 2 by the second drive cylinder 45. The support frame 3 drives the linkage 5 to disengage from the linkage hole 8. At this time, the linkage 5 drives the limiting part 47 through the connecting rod 48, so that the limiting part 47 cooperates with the support plate 10 to squeeze the second reset spring 46. Then, the air supply to the second drive cylinder 45 is stopped. The elastic restoring force of the second reset spring 46 pushes the limiting part 47 to reset. The limiting part 47 drives the linkage 5 to re-insert into the linkage hole 8 through the connecting rod 48. The linkage 5 drives the support frame 3 to approach the throwing rod 2 and the two cooperate to clamp the wrench.

[0060] Example 7:

[0061] The difference between Example 7 and Example 1 is that, as Figure 9 As shown, the driving component 4 includes a motor 41 and a lead screw 42. The output end of the motor 41 is connected to the lead screw 42. A clamping bracket 9 is installed on the throwing rod 2. The support frame 3 is slidably mounted on the clamping bracket 9. A movable frame 43 is slidably mounted on the clamping bracket 9. The lead screw 42 passes through the support frame 3 and the two are threaded together. The lead screw 42 passes through the movable frame 43 and the two are threaded together. The linkage component 5 is mounted on the movable frame 43.

[0062] The motor 41 drives the lead screw 42 to rotate, causing the movable frame 43 and the support frame 3 to move along the axis of the lead screw 42. This allows the support frame 3 to move closer to or further away from the throwing rod 2, and the movable frame 43 to drive the linkage 5 to insert or disengage from the linkage hole 8. By using the motor 41 in conjunction with the lead screw 42 to drive the sliding of the support frame 3 and the linkage 5, the accuracy of their sliding can be effectively guaranteed.

[0063] Example 8:

[0064] like Figures 1 to 10 As shown, a wrench polishing machine includes an anti-bounce mechanism, a rotary drive source 1, a polishing mechanism 7, and a feeding assembly 11. The rotary drive source 1 is used to drive the throwing rod 2 to rotate, and to cause the support frame 3 to drive the wrench to rotate around the throwing rod 2 and cooperate with the polishing mechanism 7 to complete the polishing of the side of the wrench. The feeding assembly 11 is used to disengage the polished wrench from the throwing rod 2 and the support frame 3.

[0065] In this embodiment, the polishing mechanism 7 adopts the existing belt polishing machine, and its specific structure will not be described in detail. As the wrench rotates around the polishing rod 2 and comes into contact with the sanding belt, the polishing of the wrench is completed.

[0066] It should be noted that in the current technology, two polishing devices are usually required to polish the side of the wrench. In this embodiment, the polishing of the side of the wrench can be completed by rotating the wrench and cooperating with a single polishing mechanism 7, which reduces the number of polishing mechanisms 7, effectively reduces costs, simplifies the control program, and reduces space occupation.

[0067] The unloading assembly 11 includes an unloading cylinder 111 and an unloading component 112. The unloading cylinder 111 is used to drive the unloading component 112 to push the polished wrench away from the throwing rod 2 and the support frame 3. The unloading cylinder 111 and the unloading component 112 can achieve automated unloading of the wrench, which can effectively improve production efficiency.

[0068] In this embodiment, the unloading component 112 includes a material ejection top plate 1121. The material ejection top plate 1121 is driven by the unloading cylinder 111, so that the material ejection top plate 1121 supports the wrench, thereby pushing the wrench away from the throwing rod 2 and the support frame 3.

[0069] It should be noted that this embodiment mainly describes the polishing process of the polishing machine for wrenches, but it can also be used to polish other tools, and there is no limitation on this.

[0070] Example 9:

[0071] The difference between Example 9 and Example 8 is that, as Figure 11 As shown, in this embodiment, the unloading component 112 includes a top material block 1122 made of rubber. The top material block 1122 is provided with an inclined surface 11221. The unloading cylinder 111 drives the top material block 1122, causing the top material block 1122 to support the wrench and push the wrench away from the throwing rod 2 and the support frame 3. During the process of pushing the wrench away, due to the action of the inclined surface 11221, the wrench tilts directly towards the inclined surface 11221 until it falls.

[0072] Example 10:

[0073] The difference between Example 10 and Example 8 is that, as Figure 12As shown, the unloading assembly 11 includes a lifting cylinder 113, a clamping robot 114, and a linear drive module 115. The linear drive module 115 is connected to the lifting cylinder 113 and is used to drive the lifting cylinder 113 to slide horizontally. The output end of the lifting cylinder 113 is connected to the clamping robot 114 and is used to drive the clamping robot 114 to slide vertically. The clamping robot 114 is used to clamp the wrench. The clamping robot 114 and the linear drive module 115 are existing technologies, and their specific structures will not be described in detail.

[0074] Specifically, the linear drive module 115 drives the lifting cylinder 113 to move above the wrench, the lifting cylinder 113 drives the clamping robot 114 to approach the wrench, the clamping robot 114 clamps the wrench, then the lifting cylinder 113 drives the clamping robot 114 and the wrench it clamps away from the throwing rod 2 and the support frame 3, and then the linear drive module 115 drives the lifting cylinder 113, the clamping robot 114 and the wrench it clamps to the unloading point, and places the wrench at the unloading point.

[0075] Example 11:

[0076] The difference between Example 11 and Example 8 is that, as Figure 13 As shown, in this embodiment, the wrench feeder 14 is used for feeding. The wrench feeder 14 is located on one side of the wrench polishing machine. The unpolished wrenches on the wrench feeder 14 can be placed on the throwing rod 2 and the support frame 3 by the robot arm. Of course, the polished wrenches can also be put back on the wrench feeder 14 until all the wrenches on the wrench feeder 14 are polished before the entire wrench feeder 14 is transported, which can effectively improve production efficiency.

[0077] Example 12:

[0078] The difference between Example Twelve and Example Eight is that, as Figures 14-16 As shown, in this embodiment, the throwing rod 2 includes a shaft 21 and a bushing 22. The shaft 21 is movably inserted through the bushing 22, and the bushing 22 supports the wrench. The wrench is placed outside the shaft 21, and the shaft 21 limits the wrench. The driving component 4, the support frame 3, and the locking assembly 6 are all connected to the bushing 22. The bushing 22 is connected to the output end of the rotary driving source 1. The rotary driving source 1 drives the bushing 22 to rotate relative to the shaft 21, while the shaft 21 can slide and rise relative to the bushing 22. As for how to drive the shaft 21 to slide and rise relative to the bushing 22, a linear driving source in the prior art can be used, which will not be described in detail here.

[0079] The unloading assembly 11 includes a telescopic cylinder 116, a guide rod 117, a magnet 118, and a baffle 119. The output end of the telescopic cylinder 116 is connected to the guide rod 117, and the magnet 118 is located at the end of the guide rod 117. During unloading, the shaft 21 slides down relative to the bushing 22, and the telescopic cylinder 116 drives the guide rod 117 to extend below the wrench. At this time, the magnet 118 attracts the wrench. Then, the telescopic cylinder 116 drives the guide rod 117 to retract and pull the wrench. During the retraction process of the guide rod 117, the wrench is blocked by the baffle 119, causing the wrench to fall directly off the guide rod 117, thus completing the unloading.

[0080] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model; those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
