Description

Technical Field

[0001] This utility model relates to the field of guide post processing technology, specifically to an anti-deformation adjustable clamping mechanism for guide post processing. Background Technology

[0002] Guide pillars are accessories commonly used to connect upper and lower molds. They are cylindrical pins used for precise positioning. Their presence ensures that the cylinder guides the upper mold to approach the lower mold accurately, preventing changes in the shape of the finished product during pressing. To facilitate the processing of guide pillars, clamping mechanisms are used on both sides for clamping and limiting.

[0003] In the past, most clamping mechanisms were customized according to the specifications of the guide posts. It was difficult to adjust them according to the specifications of different guide posts during assembly, and their application range was quite limited. The clamping force was also inconvenient to adjust. The fixed guide posts were easy to detach from the location under the action of external force, which was not safe, and the guide posts would also deform.

[0004] Now, a novel anti-deformation adjustable clamping mechanism for guide post machining is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-deformation adjustable clamping mechanism for guide post processing, so as to solve the problem of inconvenient adjustment of clamping distance mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-deformation adjustable clamping mechanism for guide post processing, comprising a frame, a housing fixed to the top of the frame, a worm gear movably connected between the front and rear sides of the right side inside the housing, a worm wheel movably connected between the upper and lower sides of the left side inside the housing, a motor fixed to the right side of the front end of the housing, a through groove provided inside the upper left corner of the frame, a screw threadedly connected between the housing and the worm wheel, a guide rod fixed to the upper left corner of the screw, a pressure plate fixed to the bottom of the screw, a support pad laterally fixed to the bottom of the frame, and a guide post laterally inserted between the pressure plate and the support pad.

[0007] As a further technical solution of this utility model, the output end of the second motor is fixedly connected to the worm gear at the rear, and the guide rod is embedded in the through groove.

[0008] As a further technical solution of this utility model, support rods are fixed to the lower sides of the frame, and a lower guide wheel is movably connected between the front and rear of the top of the support rod. A connecting frame is fixed between the two sides of the top of the pressure plate, and a cylinder is fixed to the two sides of the top of the connecting frame. A bracket is fixed to the bottom of the piston rod of the cylinder, and an upper guide wheel is movably connected between the front and rear of the bracket. A motor is fixed to the front end of the bracket.

[0009] As a further technical solution of this utility model, the output end of the motor is fixedly connected to the upper guide wheel, and the specifications of the upper guide wheel and the lower guide wheel are matched.

[0010] As a further technical solution of this utility model, a column is fixed at the bottom of the frame, and a slider is fixed below the column. The slider has a groove inside, and a roller is movably connected between the front and back of the groove. A motor is fixed at the front end of the slider. A slide rail is sleeved between the two sides of the slider, and a slide track is provided between the left and right sides inside the slide rail. A slot is provided horizontally above the slide track.

[0011] As a further technical solution of this utility model, the slider slides left and right along the inner wall of the slide rail, and the output end of the motor is fixedly connected to the roller at the rear.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the anti-deformation adjustable clamping mechanism for guide post processing not only realizes multiple clamping methods and facilitates the transfer of guide posts, but also realizes the adjustment of clamping distance;

[0013] (1) By fixing a pressure plate at the bottom of the screw, after adjusting the distance between the frames on both sides, the guide column is placed horizontally on the support pad. The motors installed at the front end of each housing are started to guide the worm connected to its output end, forcing the worm wheel meshed on its left side to rotate. Under the restriction of the guide rod in the through groove, the screw and pressure plate are raised and lowered vertically through the thread groove inside the worm wheel. The height and force of the pressure plate pressing the guide column are adjusted to avoid damage to the guide column. Both the pressure plate and the support pad are equipped with sponge blocks, which can adjust the shape of the pressing according to the surface of the guide column for subsequent clamping.

[0014] (2) A lower guide wheel is movably connected between the front and rear of the top of the support rod, and an upper guide wheel is movably connected between the front and rear of the bracket. The support rods on both sides of the frame are respectively attached to the guide column through the lower guide wheel, and the connecting frame fixed on both sides of the top of the pressure plate guides the cylinder to rise and fall. After clamping, the pressure plate can be slightly lifted. The upper guide wheel controlled by the motor cooperates with the lower guide wheel installed in the support rod to horizontally transmit the guide column so that it leaves the clamping mechanism without manual pulling.

[0015] (3) Rollers are movably connected between the front and rear of the groove, and two sliders supporting the columns are installed in the slide rail. When the motor is turned on, the rollers in the slider can be guided to rotate, so that the two sets of sliders can be moved along the inner wall of the slide rail, thereby guiding the columns and frame installed on the top to move. The spacing of the clamping mechanism can be adjusted according to the length of the guide column, thus expanding the applicability of the device. Attached Figure Description

[0023] The output end of motor 21 is fixedly connected to worm gear 21, and guide rod 14 is embedded in through groove 26;

[0024] Specifically, such as Figure 1 and Figure 2As shown, after adjusting the spacing between the two sides of the frame 7, the guide post 9 is placed horizontally on the support pad 8. The motor 12 installed at the front end of each housing 11 is started, which guides the worm gear 21 connected to its output end, forcing the worm wheel 22 meshed on its left side to rotate. Under the restriction of the guide rod 14 in the through groove 26, the screw 13 and the pressure plate 10 are raised and lowered vertically through the threaded groove inside the worm wheel 22. The height and force of the pressure plate 10 pressing the guide post 9 are adjusted to avoid damage to the guide post 9.

[0025] Support rods 20 are fixed to the lower sides of the frame 7, and lower guide wheels 19 are movably connected between the front and back of the top of the support rods 20. A connecting frame 16 is fixed between the two sides of the top of the pressure plate 10, and cylinders 15 are fixed to the two sides of the top of the connecting frame 16. A bracket 17 is fixed to the bottom of the piston rod of the cylinder 15, and an upper guide wheel 18 is movably connected between the front and back of the bracket 17. A motor 23 is fixed to the front end of the bracket 17. The output end of the motor 23 is fixedly connected to the upper guide wheel 18. The specifications of the upper guide wheel 18 and the lower guide wheel 19 are matched.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, the support rods 20 on both sides of the frame 7 are attached to the guide post 9 through the lower guide wheel 19, while the connecting frame 16 fixed on both sides of the top of the pressure plate 10 guides the cylinder 15 to rise and fall. After clamping, the pressure plate 10 can be slightly raised, and the upper guide wheel 18 is controlled by the motor 23 to cooperate with the lower guide wheel 19 installed in the support rod 20 to horizontally transmit the guide post 9 so that it can leave the clamping mechanism.

[0027] A column 6 is fixed to the bottom of the frame 7, and a slider 4 is fixed below the column 6. The slider 4 has a groove 25 inside, and a roller 3 is movably connected between the front and back of the groove 25. A motor 5 is fixed to the front of the slider 4.

A slot 24 is provided horizontally above the slide track 2. The slider 4 slides left and right along the inner wall of the slide track 2. The output end of the motor 5 is fixedly connected to the roller 3 at the rear.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, two sliders 4 supporting the columns 6 are installed in the slide rail 1. After the motor 5 is turned on, the rollers 3 in the sliders 4 can be guided to rotate, so that the two sets of sliders 4 can be translated along the inner wall of the slide rail 2, thereby guiding the columns 6 and the frame 7 installed on the top to move.

[0030] Furthermore, the cylinder 15 includes a cylinder barrel, piston, piston rod, end cap, seal, solenoid valve, air source, and air passage. The cylinder 15 is a fully disclosed prior art, and the air supply method is implemented in a conventional manner, so it will not be described in detail.

[0031] Working principle: In use, the slide rail 1 has two sliders 4 supporting the columns 6. After the motor 5 is turned on, the rollers 3 in the sliders 4 are rotated, causing the two sets of sliders 4 to move along the inner wall of the slide rail 2, thereby guiding the columns 6 and frame 7 installed on top to move. The spacing of the clamping mechanism can be adjusted according to the length of the guide column 9. Then, the guide column 9 is placed horizontally on the support pad 8. The motor 12 installed at the front end of the housing 11 is started, guiding the worm gear 21 connected to its output end, forcing the worm wheel 22 meshed on its left side to rotate, and the guide rod 14 in the through groove 26 is limited. Under control, the screw 13 and pressure plate 10 are vertically raised and lowered through the threaded groove inside the worm gear 22, adjusting the height and force of the pressure plate 10 pressing the guide post 9 to avoid damage to the guide post 9. Both the pressure plate 10 and the support pad 8 are equipped with sponge blocks, which can adjust the shape during pressing according to the surface of the guide post 9. The support rods 20 on both sides of the frame 7 are respectively attached to the guide post 9 through the lower guide wheel 19. The connecting frame 16 fixed on both sides of the top of the pressure plate 10 guides the cylinder 15 to rise and fall. After clamping, the pressure plate 10 can be slightly raised, and the upper guide wheel 18 is controlled by the motor 23 to cooperate with the lower guide wheel 19 installed in the support rod 20 to horizontally transmit the guide post 9.
