Description

Technical Field

[0001] This utility model relates to the field of clamping mechanism technology, specifically to a product positioning clamping mechanism. Background Technology

[0002] L-shaped connectors are commonly used to connect two objects. To ensure connection strength, they are usually made of metal. During the manufacturing process, burrs may remain on the edges of the L-shaped connector. To ensure comfort during use, these edges often need to be ground. Before grinding, the L-shaped connector is clamped and positioned using a clamping mechanism, and then the edges are ground using a grinding mechanism.

[0003] Currently, commonly used clamping mechanisms generally include multiple movable jaws. The jaws approach each other and abut against both ends of the L-shaped connector to position it. To prevent damage to the L-shaped connector when the jaws approach each other, rubber pads are usually fixedly connected to the jaws. For example, a clamping assembly for processing metal parts disclosed in patent CN222243719U requires the replacement of the jaws along with the rubber pads after a period of use, which is wasteful and needs to be improved. Summary of the Invention

[0004] The purpose of this utility model is to provide a product positioning and clamping mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A product positioning clamping mechanism includes a base platform, a detachable rail on the base platform, a movable fixed seat opposite to the fixed seat in the rail, a liftable fixed plate on the fixed seat, and a driving component on the fixed seat for driving the fixed plate to lift.

[0007] The mounting base is also equipped with limiting components for restricting the driving components;

[0008] Both the fixed base and the fixed plate have detachable buffer components on their opposing surfaces. The bottom surface of the fixed plate has a notch. The buffer component includes a buffer block. The fixed plate has a connecting hole. The buffer block has a connecting rod extending from the connecting hole. A nut is threaded onto the connecting rod. The nut is used to connect the buffer block to the fixed plate.

[0009] Preferably, a T-shaped groove is provided in the track along its length, and a T-shaped block is provided on the bottom wall of the fixing seat, which slides in the T-shaped groove.

[0010] Preferably, the fixed base has a limiting groove along its height direction, the fixed plate has a limiting block that slides in the limiting groove, and the fixed base has a rotatable shaft with a thread passing through the limiting block. The rotation of the shaft is used to drive the limiting block to rise and fall.

[0011] Preferably, the limiting component includes a movable friction block disposed in the limiting groove. One side of the friction block is fitted to the rotating shaft, and the other side of the friction block is provided with an extension rod extending through the fixed seat. The extension rod is rotatably connected to the friction block. A spring is provided on the extension rod located between the friction block and the fixed seat. The spring is used to push the friction block closer to the rotating shaft. An extension plate is provided on the extension rod located outside the fixed seat. Pulling the extension plate is used to move the friction block away from the rotating shaft.

[0012] Preferably, the extension plate is provided with a plug rod, and the side wall of the fixing seat is provided with a through hole and a locking hole. The through hole is provided through the fixing seat, and the locking hole is not provided through the fixing seat. The plug rod is inserted into the locking hole to move the friction block away from the extension rod.

[0013] Preferably, the bottom end of the fixed plate is provided with a notch, the buffer includes a buffer block, the fixed plate is provided with a connecting hole, the buffer block is provided with a connecting rod extending from the connecting hole, and a nut is threaded onto the connecting rod. The nut is used to connect the buffer block and the fixed plate.

[0014] Preferably, the side wall of the track is provided with multiple positioning holes, which are arranged along the moving direction of the fixed seat. The fixed seat is provided with an extension, and the extension is provided with a hand-tightening bolt that can be inserted into the fixed seat.

[0015] Preferably, the base is provided with mounting holes, and countersunk bolts are provided at both ends of the track. The countersunk bolts are used to connect the track to the base.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, by detaching the buffer component from the fixed base and fixed plate, allows the buffer component to be removed from the fixed base and fixed plate and replaced after wear and tear over a period of use, thus ensuring the buffering effect on the L-shaped connector. Compared with the existing technology, this application eliminates the need to replace the buffer component along with the fixed base and fixed plate, reducing resource waste.

[0018] This utility model, through the adjustable mounting of the fixing plate on the fixing seat, allows the distance between the fixing seat and the fixing plate to be adjusted. When it is necessary to fix L-shaped connectors with different thicknesses on both sides, the fixing plate on one of the fixing seats can be adjusted individually so that the fixing plate fits against the L-shaped connector and cooperates with the fixing seat to fix the L-shaped connector.

[0032] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0033] The following is in conjunction with the appendix Figures 1-6 This embodiment will be described in further detail.

[0034] Please see Figures 1-2A product positioning clamping mechanism in this embodiment includes a base platform 100, a detachable track 110 on the base platform 100, a movable fixed seat 120 opposite to the track 110, a liftable fixed plate 121 on the fixed seat 120, and a driving component on the fixed seat 120 for driving the fixed plate 121 to rise and fall.

[0035] The mounting base 120 is also provided with a limiting element for restricting the driving component;

[0036] Both the fixed base 120 and the fixed plate 121 have detachable buffer components on their opposite surfaces. The bottom end of the fixed plate 121 has a notch 510. The buffer component includes a buffer block 220. The fixed plate 121 has a connecting hole. The buffer block 220 has a connecting rod 311 extending from the connecting hole. A nut 310 is threaded onto the connecting rod 311. The nut 310 is used to connect the buffer block 220 to the fixed plate 121.

[0037] In this embodiment, the positioning clamping mechanism is installed on a grinding machine (not shown in the figure) for use. Specifically, the base 100 is detachably installed on the upper end face of the grinding machine by screws. Before grinding the L-shaped connector 130, a fixed seat 120 is first fixed, and then one end of the L-shaped connector 130 is attached to the fixed seat 120. Next, another fixed seat 120 is moved so that the other end of the L-shaped connector 130 is attached to the other fixed seat 120, and the other fixed seat 120 is fixed. Finally, the fixing plates 121 on the two fixed seats 120 are moved down in sequence to fix both ends of the L-shaped connector 130 respectively. Then, the edge of the L-shaped connector 130 is ground by the grinding mechanism of the grinding machine (not shown in the figure).

[0038] The detachable design of the buffer component on the fixed base 120 and the fixed plate 121 allows the buffer component to be removed from the fixed base 120 and the fixed plate 121 and replaced when it wears out after a period of use, thus ensuring the buffering effect on the L-shaped connector 130. Compared with the existing design, this embodiment does not require the buffer component to be replaced along with the fixed base 120 and the fixed plate 121, reducing the waste of resources.

[0039] The lower end of the connecting rod 311 is fixedly connected to the buffer block 220. After a period of use, when the buffer block 220 wears out, the nut 310 can be rotated to dislodge the connecting rod 311 and move the buffer block 220 away from the fixing plate 121. Then, a new fixing plate 121 is installed in the notch 510, and the connecting rod 311 passes through the connecting hole and is threaded onto the connecting rod 311 by the nut 310, so that the buffer block 220 is fixed. Specifically, when the buffer block 220 is placed in the notch 510, one side of the buffer block 220 will abut against the side wall of the fixing seat 120, so that the buffer block 220 is restricted and does not rotate circumferentially, so that the nut 310 can be turned to fix it.

[0040] Specifically, one side of the fixed base 120 is bent at the bottom to form an extension block 122 opposite to the fixed plate 121. The upper end face of the extension block 122 is also provided with a notch 510, and a connecting hole is also opened in the notch 510 to pass through the extension block 122. The connecting rod 311 on the buffer block 220 is also provided through the connecting hole and fixed by the nut 310. When the buffer block 220 on the extension block 122 is damaged, it can be replaced. Thus, both the upper and lower end faces of the L-shaped connector 130 can be buffered, so that it has a better buffering effect.

[0041] Specifically, in order to improve the buffering effect of the buffer block 220, rubber pads are provided on the opposite sides of the two buffer blocks 220 on the upper and lower sides.

[0042] The adjustable height of the fixing plate 121 on the fixing base 120 allows for adjustment of the distance between the fixing base 120 and the extension block 122. When it is necessary to fix L-shaped connectors 130 with different thicknesses on both sides, the height of the fixing plate 121 on either fixing base 120 can be adjusted individually so that the fixing plate 121 fits against the L-shaped connector 130 and moves in coordination with the fixing base 120 to fix the L-shaped connector 130, making it more versatile.

[0043] The slidable arrangement of the fixing base 120 within the track 110 allows for adjustment of the distance between the fixing bases 120, thereby securing L-shaped connectors 130 of different lengths.

[0044] The limiting component can restrict the driving component, reducing the possibility that the L-shaped connector 130 will vibrate during grinding, causing the driving component to malfunction and the fixing plate 121 to move erroneously, thus accidentally releasing the fixing of the L-shaped connector 130.

[0045] Combination Figures 1-6As shown, in this embodiment, a T-shaped groove 610 is provided in the track 110 along its length direction, and a T-shaped block 200 is provided on the bottom wall of the fixed seat 120, which slides in the T-shaped groove 610. The T-shaped block 200 is fixedly connected to the lower end of the fixed seat 120.

[0046] In this embodiment, the T-shaped block 200 can slide within the T-shaped groove 610. By setting the T-shaped groove 610 and the T-shaped block 200, the fixed seat 120 can be restricted when moving, that is, it can only move along the extension direction of the T-shaped groove 610.

[0047] Specifically, the fixed base 120 is provided with a fixing member for fixing the movable fixed base 120. The fixing member includes an extension 210 located opposite to the side wall of the fixed base 120. The outer side wall of the track 110 is provided with a plurality of positioning holes 611. The plurality of positioning holes 611 are evenly arranged along the moving direction of the fixed base 120. The fixed base 120 is provided with an extension 210. The extension 210 is fixedly connected to the lower side wall of the fixed base 120. A hand-tightening bolt 211 that can be inserted into the positioning hole 611 is threaded onto the extension 210. When the hand-tightening bolt 211 is inserted into the positioning hole 611, the movable fixed base 120 can be fixed. When it is necessary to move the fixed base 120, the hand-tightening bolt 211 can be rotated so that one end of it is disengaged from the positioning hole 611.

[0048] In practical use, the positioning hole 611 is located on the opposite outer wall of the track 110. When the L-shaped connector 130 is being polished, the debris is less likely to fall into the positioning hole 611. This reduces the impact of debris on the hand-tightening bolt 211 extending into the positioning hole 611. The hand-tightening bolt 211 can be operated on both sides of the track 110 to fix the fixing seat 120, which is convenient for use.

[0049] Combination Figures 1-6 As shown, in this embodiment, the base 100 is provided with mounting holes 601, and countersunk bolts 602 are provided at both ends of the track 110. The countersunk bolts 602 are used to connect the track 110 and the base 100.

[0050] In this embodiment, the countersunk bolt 602 is threaded to the mounting hole 601, which allows the track 110 to be disassembled and assembled on the base 100. When the L-shaped connector 130 after grinding is removed, metal debris may fall into the T-shaped groove 610, which may affect the movement of the subsequent fixing seat 120. At this time, the track 110 can be removed from the base 100 and placed at an angle to discharge the metal debris in the T-shaped groove 610.

[0051] Combination Figures 1-5As shown, in this embodiment, a limiting groove 320 is provided in the fixed base 120 along its height direction, a limiting block 500 is provided on the fixed plate 121 that slides in the limiting groove 320, and a rotatable rotating shaft 230 is provided in the fixed base 120. The rotating shaft 230 is threaded through the limiting block 500, and the rotation of the rotating shaft 230 is used to drive the limiting block 500 to rise and fall.

[0052] In this embodiment, the limiting groove 320 is set along the height direction of the fixed base 120, the limiting block 500 is fixedly connected to the fixed plate 121, and the rotating shaft 230 is rotatably installed in the fixed base 120 through the bearing. Since the rotating shaft 230 is threaded through the limiting block 500 and the limiting block 500 is restricted by the limiting groove 320, when the rotating shaft 230 rotates, the limiting block 500 will rise and fall along the axial direction of the rotating shaft 230, approaching or moving away from the extension block 122, thereby fixing or releasing the L-shaped connector 130.

[0053] Specifically, the top end of the rotating shaft 230 extends through the fixed base 120 and is set out of the limiting groove 320. In order to facilitate the rotation of the rotating shaft 230, the top end of the rotating shaft 230 is provided with a hand-tightening part 231.

[0054] Combination Figures 1-4 As shown, in this embodiment, the limiting member includes a movable friction block 300 disposed in the limiting groove 320. One side of the friction block 300 is attached to the rotating shaft 230, and the other side of the friction block 300 is provided with an extension rod 301 extending through the fixing seat 120. The extension rod 301 is rotatably connected to the friction block 300. A spring 305 is provided on the extension rod 301 located between the friction block 300 and the fixing seat 120. The spring 305 is used to push the friction block 300 closer to the rotating shaft 230. An extension plate 302 is provided on the extension rod 301 located outside the fixing seat 120. Pulling the extension plate 302 is used to drive the friction block 300 away from the rotating shaft 230.

[0055] In this embodiment, the side wall of the fixed base 120 is provided with a circular hole for the extension rod 301 to pass through. One end of the extension rod 301 extends out of the fixed base 120 through the circular hole, and the other end of the extension rod 301 is rotatably mounted on the friction block 300 through a bearing. This enables the extension rod 301 to be rotatable and movable on the fixed base 120. One end of the spring 305 abuts against the fixed base 120, and the other end of the spring 305 abuts against the friction block 300.

[0056] Under the elastic force of the spring 305, the spring 305 can always push the friction block 300 to move towards the rotating shaft 230. Under the action of friction, the rotating shaft 230 is not easy to rotate. Even if the L-shaped connector 130 vibrates due to grinding, the friction between the friction block 300 and the rotating shaft 230 makes it difficult for the rotating shaft 230 to rotate, so as to prevent the fixing plate 121 from moving and accidentally releasing the fixing of the L-shaped connector 130.

[0057] Specifically, the end of the friction block 300 near the rotating shaft 230 is arc-shaped to match it, thereby enabling the friction block 300 to fit the rotating shaft 230 better.

[0058] It should be noted that the two opposite side walls of the friction block 300 slide against the side wall of the limiting groove 320, thereby restricting the friction block 300 and preventing it from rotating circumferentially along the extension rod 301, thus affecting its actual use.

[0059] Combination Figures 1-4 As shown, in this embodiment, the extension plate 302 is provided with a rod 304 opposite to each other, and the side wall of the fixing seat 120 is provided with a through hole 400 and a locking hole 240 opposite to each other. The through hole 400 is provided through the fixing seat 120, and the locking hole 240 is not provided through the fixing seat 120. The rod 304 is inserted into the locking hole 240 to make the friction block 300 move away from the extension rod 301.

[0060] In this embodiment, the insertion rod 304 is fixedly connected to the plate surface of the extension plate 302 near the fixing base 120;

[0061] When the insertion rod 304 is aligned with the through hole 400, under the elastic force of the spring 305, the insertion rod 304 can move towards the fixed base 120. Since the through hole 400 penetrates the fixed base 120, one end of the insertion rod 304 can penetrate the fixed base 120 and extend into the limiting groove 320. At this time, the friction block 300 is close to the rotating shaft 230 to increase the friction between the two. When the insertion rod 304 is aligned with the locking hole 240, under the elastic force of the spring 305, the insertion rod 304 can move towards the fixed base 120. Since the locking hole 240 does not penetrate the fixed base 120, when one end of the insertion rod 304 extends into the locking hole 240, the friction block 300 does not contact the rotating shaft 230, so that the rotating shaft 230 can be rotated to raise and lower the fixed plate 121.

[0062] In order to facilitate pulling and rotating the extension plate 302, a handle 303 is provided on the plate surface of the extension plate 302 away from the fixed base 120.

[0063] Before grinding the L-shaped connector 130, in this embodiment, a fixing seat 120 is first fixed on the track 110. Then, one end of the L-shaped connector 130 is attached to the fixing seat 120. Next, another fixing seat 120 is moved so that the other end of the L-shaped connector 130 is attached to the other fixing seat 120 and the other fixing seat 120 is fixed. Then, the fixing plates 121 on the two fixing seats 120 are moved down in sequence to fix both ends of the L-shaped connector 130 respectively, so that the positioning clamping mechanism can position and fix the L-shaped connector 130 so that the L-shaped connector 130 can be ground in the future.

[0064] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
