Description

A caliper screw locking mechanism Technical Field

[0001] This utility model belongs to the field of caliper processing equipment, and in particular relates to a caliper screw locking mechanism. Background Technology

[0002] In existing screw feeding and installation technologies, mechanical clamping is typically used for screw positioning and transport. However, this method has some limitations. Firstly, the mechanical clamping structure is relatively complex, requiring precise mechanical adjustments to accommodate screws of different sizes, which increases manufacturing costs and maintenance difficulty. Secondly, the mechanical clamping structure often cannot effectively adapt to errors in screw outer diameter, easily leading to problems such as loosening, falling off, or jamming during transport, thus affecting production efficiency and product quality. Furthermore, in some automated production scenarios, high precision and stability are required for screw installation, and traditional feeding and installation methods are insufficient to meet these high-precision and high-stability requirements. Summary of the Invention

[0003] The purpose of this invention is to provide a caliper screw locking mechanism, which aims to solve the technical problems of unstable screw clamping and poor adaptability in the prior art.

[0004] To achieve the above objectives, this utility model provides a caliper screw locking mechanism, including a locking assembly and a feeding assembly. Both the locking assembly and the feeding assembly are mounted on a frame. The locking assembly includes a guide post and a push rod. The guide post is disposed on the frame and has a central hole extending vertically. The push rod slides vertically through the central hole and can rotate around its own axis. The feeding assembly is configured to push the screw into the central hole. The push rod is configured to push the screw out of the central hole and screw it into the screw mounting hole on the caliper. The guide post consists of a cylindrical body, a clamping block, and an elastic rubber sleeve. The bottom of the cylindrical body has a mounting groove. The clamping block is located in the mounting groove and together with the cylindrical body forms the central hole. The rubber sleeve is fitted over the cylindrical body and simultaneously wraps the cylindrical body and the clamping block.

[0005] Optionally, the cylindrical body has a first groove, the clamping block has a second groove, the first groove and the second groove are combined to form an annular groove, and the inner ring of the rubber sleeve has an annular protrusion that can cooperate with the annular groove at the position corresponding to the annular groove.

[0006] Optionally, the clamping block has a protrusion along its radial direction, and the cylindrical body has a recess along its radial direction. The protrusion can cooperate with the recess to limit the position of the clamping block relative to the cylindrical body in the vertical direction.

[0007] Optionally, the outer diameter of the cylindrical body gradually decreases near the mounting groove and forms a tapered slope, and the rubber sleeve is provided with a guide slope that matches the tapered slope at the position corresponding to the tapered slope.

[0008] Optionally, the locking assembly further includes a slide block configured to reciprocate between a loading station and an installation station relative to the frame. The guide post and the push rod are both disposed on the slide block. The feeding assembly is connected to the vibratory feeder and is used to receive screws output by the vibratory feeder and sequentially transfer the screws to the loading station of the frame. The feeding assembly includes a pusher mounted on the loading station of the frame. The pusher is configured to push the screws located at the loading station upwards into the center hole of the push rod.

[0009] Optionally, the feeding assembly includes a pusher plate that is slidably disposed on the frame in a horizontal direction. The frame also has a first receiving position and a second receiving position. The pusher plate is configured to reciprocate between the first receiving position and the second receiving position. When the pusher plate is located at the first receiving position, it can receive the screw output by the vibratory feeder. When the pusher plate moves to the second receiving position, it can synchronously move the screw to the second receiving position.

[0010] Optionally, the push plate has a transfer groove for receiving the screw output by the vibratory feeder, and the width and length of the transfer groove are both equal to the outer diameter of the screw.

[0011] Optionally, the feeding assembly further includes a flipping block disposed on the frame, the flipping block being configured to flip between the second receiving position and the loading position, the flipping block being provided with a material transfer hole, the frame being provided with another pusher in the area corresponding to the second receiving position, the pusher being configured to push the screw located at the second receiving position upward into the material transfer hole, and the pusher located at the loading position being configured to push the screw located at the loading position upward into the center hole.

[0012] Compared with the prior art, the above-mentioned technical solutions of one or more of the caliper screw locking mechanisms provided in this utility model embodiment have at least one of the following technical effects: The cylindrical body and clamping block in this utility model can be spliced ​​together to form a central hole. Since the cylindrical body and clamping block are covered with a rubber sleeve, the gap between the cylindrical body and clamping block can be finely adjusted by the deformation of the rubber sleeve while maintaining the central hole. Specifically, during processing, the feeding component can first push the screw upwards, allowing the screw to enter the central hole. At this time, due to the elastic force of the rubber sleeve, the screw can be clamped between the cylindrical body and clamping block and will not fall out of the central hole. Then, when the feeding component is in the position corresponding to the caliper (not shown in the figure), the push rod can move downwards and push the screw into the screw mounting hole of the caliper. This utility model can achieve elastic clamping of the screw by setting the rubber sleeve structure, ensuring clamping stability while also adapting to the screw's outer diameter error within a certain range.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0035] As shown in Figures 1 to 8, this utility model embodiment provides a caliper screw locking mechanism, including a locking component 200 and a feeding component 600.

[0036] Both the locking assembly 200 and the feeding assembly 600 are mounted on the frame 100. The locking assembly 200 includes a guide post 300 and a push rod 400. The guide post 300 is mounted on the frame 100 and has a central hole 310 extending vertically. The push rod 400 slides vertically through the central hole 310 and can rotate around its own axis. The feeding assembly 600 is configured to push the screw 700 into the central hole 310. The push rod 400 is configured to... The screw 700 inside the center hole 310 can be pushed out of the center hole 310 and screwed into the screw mounting hole on the caliper. The guide post 300 is composed of a cylindrical body 320, a clamping block 330 and an elastic rubber sleeve 340. The bottom of the cylindrical body 320 is provided with a mounting groove 321. The clamping block 330 is located at the mounting groove 321 and together with the cylindrical body 320 forms the center hole 310. The rubber sleeve 340 is fitted outside the cylindrical body 320 and simultaneously wraps the cylindrical body 320 and the clamping block 330.

[0037] It is understood that the cylindrical body 320 and the clamping block 330 in this utility model can be spliced ​​together to form the central hole 310. Since the cylindrical body 320 and the clamping block 330 are covered with a rubber sleeve 340, the gap between the cylindrical body 320 and the clamping block 330 can be finely adjusted by the deformation of the rubber sleeve 340 while maintaining the central hole 310. Specifically, during processing, the feeding assembly 600 can first push the screw 700 upward so that the screw 700 enters the central hole 310. At this time, due to the elastic force of the rubber sleeve 340, the screw 700 can be clamped between the cylindrical body 320 and the clamping block 330 and will not fall out of the central hole 310. Then, when the feeding assembly 600 is in the position corresponding to the caliper (not shown in the figure), the push rod 400 can move downward and push the screw 700 into the screw mounting hole of the caliper. This utility model can achieve elastic clamping of screw 700 by setting the rubber sleeve 340 structure, which can not only ensure clamping stability, but also adapt to the outer diameter error of screw 700 within a certain range.

[0038] As shown in Figures 2 to 5, in one embodiment of this utility model, a first groove 322 is provided on the cylindrical body 320, and a second groove 331 is provided on the clamping block 330. The first groove 322 and the second groove 331 are combined to form an annular groove 350. The inner ring of the rubber sleeve 340 is provided with an annular protrusion 341 that can cooperate with the annular groove 350 at the position corresponding to the annular groove 350. The annular protrusion 341 can cooperate with the annular groove 350 to fix the position of the rubber sleeve 340 relative to the cylindrical body 320 and the position of the clamping block 330 relative to the rubber sleeve 340, thereby enabling the cylindrical body 320, the clamping block 330 and the rubber sleeve 340 to stably maintain the central hole 310.

[0039] As shown in Figures 4 and 5, in one embodiment of this utility model, the clamping block 330 is provided with a protrusion 332 along its own radial direction, and the cylindrical body 320 is provided with a recess 323 along its own radial direction. The protrusion 332 can cooperate with the recess 323 to limit the position of the clamping block 330 relative to the cylindrical body 320 in the vertical direction. When the position of the clamping block 330 relative to the cylindrical body 320 is finely adjusted in the horizontal direction, the cooperation between the protrusion 332 and the recess 323 can provide guidance for the horizontal movement of the clamping block 330 and limit the movement of the clamping block 330 in the vertical direction.

[0040] As shown in Figures 2 to 4, in one embodiment of this utility model, the outer diameter of the cylindrical body 320 gradually decreases near the mounting groove 321 and forms a tapered inclined surface 324. The rubber sleeve 340 is provided with a guide inclined surface 342 that matches the tapered inclined surface 324 at the corresponding position. The cooperation between the guide inclined surface 342 and the tapered inclined surface 324 facilitates the installation of the rubber sleeve 340. The rubber sleeve 340 can be made of deformable material, such as silicone. Such deformable materials often have some errors in processing dimensions. By setting the inclined stepped surface, the assembly impact caused by the error in the length of the rubber sleeve 340 can be reduced.

[0041] As shown in Figures 1 and 8, in one embodiment of this utility model, the locking assembly 200 further includes a slide 500, which is configured to reciprocate between the loading station 110 and the installation station 120 relative to the frame 100. As shown in Figure 1, the locking assembly 200 can slide along a first direction and reciprocate between the loading station 110 and the installation station 120 to deliver screws 700. In addition, guide posts 300 and push rods 400 are both disposed on the slide 500. The feeding assembly 600 is connected to the vibratory feeder 800. The feeding assembly 600 is used to receive the screws 700 output by the vibratory feeder 800 and sequentially deliver the screws 700 to the loading station 110 of the frame 100. The vibratory feeder 800 can arrange and output several scattered screws 700 in the same direction. This type of vibratory feeder 800 is a conventional device in the art, and its structure and principle will not be described in detail here. As shown in Figure 8, the feeding assembly 600 includes a pusher 630, which is installed at the loading station 110 on the frame 100. The pusher 630 is configured to push the screws 700 located at the loading station 110 upward into the center hole 310 of the push rod 400. Specifically, a number of screws 700 can be sequentially moved to the loading station 110. The frame 100 can also be equipped with a detection grating at the loading station 110 to detect whether any screws 700 have been moved into place at the loading station 110.

[0042] As shown in Figures 1, 6, and 7, in one embodiment of this utility model, the feeding assembly 600 includes a pusher plate 610, which is slidably disposed on the frame 100 in a horizontal direction. Specifically, as shown in Figure 7, the pusher plate 610 can slide in a second direction in the horizontal direction. Both the first and second directions are horizontal and perpendicular to each other. The frame 100 also has a first receiving position 130 and a second receiving position 140. The pusher plate 610 is configured to reciprocate between the first receiving position 130 and the second receiving position 140. When the pusher plate 610 is located at the first receiving position 130, it can receive the screws 700 output by the vibratory feeder 800. When the pusher plate 610 moves to the second receiving position 140, it can simultaneously move the screws 700 to the second receiving position 140. Then, through other transfer mechanisms, the screws 700 at the second receiving position 140 are transferred to the loading station 110. By setting the push plate 610 structure, the screws 700 output by the vibratory feeder 800 can be separated and moved sequentially to the second receiving position 140, which facilitates the transfer of individual screws 700 in subsequent processes.

[0043] As shown in Figure 7, in one embodiment of this utility model, the push plate 610 has a transfer groove 611, which is used to receive the screws 700 output by the vibratory feeder 800. The width and length of the transfer groove 611 are equal to the outer diameter of the screw 700, so that only one screw 700 can be accommodated in the transfer groove 611 at a time, which can effectively prevent interference or jamming during the screw 700 feeding process.

[0044] As shown in Figures 6 and 8, in one embodiment of this utility model, the feeding assembly 600 further includes a flipping block 620 flipped and disposed on the frame 100. The flipping block 620 is configured to flip between the second receiving position 140 and the loading position 110. Specifically, the flipping block 620 can be flipped by a motor drive. The flipping block 620 is provided with a transfer hole 621. As shown in Figure 8, the frame 100 is provided with another pusher 630 in the area corresponding to the second receiving position 140. The pusher 630 is configured to push the screw 700 located at the second receiving position 140 upward into the transfer hole 621. At this time, the top of the screw 700 located in the transfer hole 621 is facing down. After the flipping block 620 flips, the screw 700 in the transfer hole 621 is in a state with the top facing up. The pusher 630 located at the loading position 110 is configured to push the screw 700 located at the loading position 110 upward into the center hole 310.

[0045] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
