Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a stable and efficient single-station clamp quick-change mechanism. Background Technology

[0002] A single-station fixture is a tool used to fix and support workpieces during production or processing. It is typically used in scenarios requiring precision machining, measurement, assembly, or inspection of workpieces. Unlike multi-station fixtures, single-station fixtures fix and process workpieces in only one location, eliminating the need for transfer between multiple processing stations.

[0003] In practical applications, existing single-station fixtures typically use rectangular clamps to fix and hold objects. This design is suitable for most conventionally shaped workpieces. However, when it comes to clamping cylindrical workpieces, the existing fixture fixing method cannot meet the requirements. To accommodate the processing of cylindrical workpieces, workers must manually replace them with curved clamps. This process requires removing the original rectangular clamps and then installing curved clamps suitable for cylindrical workpieces. This operation is not only cumbersome but also consumes a lot of time and manpower, greatly affecting work efficiency and production speed.

[0004] Since each clamp replacement requires a long operation time and workers need to expend a lot of physical strength, this traditional clamp replacement method has significant limitations. In order to improve work efficiency, reduce manual intervention and improve the continuity of processing, there is an urgent need for a new design scheme, namely a stable and efficient single-station clamp quick-change mechanism.

[0005] Utility model content.

[0006] To address the shortcomings of existing technologies, this utility model provides a stable and efficient single-station quick-change clamping mechanism to solve the problem that in existing technologies, when encountering the need to clamp cylindrical workpieces, workers must manually change to arc-shaped clamping plates. This process requires removing the originally installed rectangular clamping plates and then installing arc-shaped clamping plates suitable for cylindrical workpieces.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a stable and efficient single-station clamp quick-change mechanism, comprising: a base plate, wherein support plates are movably connected to both sides of the top of the base plate, and further comprising:

[0008] Two movable rods are fixedly installed on the top of the support plate, and connecting parts are movably sleeved on the outer surface of both movable rods;

[0009] Two rectangular clamps are fixedly installed on the opposite side of the two connectors, and arc-shaped clamps are fixedly installed on the opposite side of the two connectors.

[0010] The outer surfaces of the two rectangular clamping plates and the two arc-shaped clamping plates are all provided with soft pads, and two pin posts are movably embedded on both sides of the inner side of the two movable rods.

[0011] Preferably, a first return spring is fixedly installed on the top of each of the four pins, and the four first return springs are divided into two groups of two, with pin slots opened on both sides of the interior of the two connectors.

[0012] Preferably, the other ends of both sets of the first return springs are fixedly installed on the top of the movable rod, and the four pin slots are matched with the pin posts.

[0013] Preferably, the top of the base plate is provided with a sliding groove, a forward rotation screw is movably embedded in the left side of the interior of the base plate, and a reverse rotation screw is fixedly installed on the right side of the forward rotation screw.

[0014] Preferably, the right outer surface of the reversing lead screw is movably embedded in the inside right side of the base plate, and both the forward lead screw and the reversing lead screw are located inside the slide groove.

[0015] Preferably, both the forward-rotating lead screw and the reverse-rotating lead screw have sliders threadedly connected to their outer surfaces, and the tops of both sliders are fixedly installed at the bottom of the support plate.

[0016] Preferably, both sliders are slidably connected inside the groove, a motor is fixedly installed on the left side of the forward rotation screw, and the bottom of the motor is fixedly installed on the top left side of the base plate.

[0017] Preferably, the bottom of the base plate is provided with a base, and the top four sides of the base plate are fixedly installed with connecting columns. The four connecting columns are movably embedded inside the base plate, and the bottom four sides of the base plate are fixedly installed with second return springs. The four second return springs are movably sleeved on the outer surface of the connecting columns.

[0018] Preferably, the other ends of the four second return springs are all fixedly installed on the top of the base, and an electric telescopic rod is fixedly embedded in the left side of the interior of the base, with a first push block fixedly installed at the other end of the electric telescopic rod.

[0019] Preferably, the first push block is slidably connected to the inner top side of the base, and a second push block is slidably connected to the top of the first push block, with the top of the second push block fixedly installed on the bottom of the base plate.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In use, when a cylindrical workpiece needs to be clamped, the operator can first pull the pin upwards, allowing it to slide upwards inside the movable rod and extend the first return spring. After it rises to a certain extent, it can disengage from the pin slot. Then, the rectangular clamping plate is pushed forward, causing the connecting piece to rotate on the outer surface of the movable rod. After the connecting piece rotates 180 degrees, the arc-shaped clamping plate is positioned inside the connecting piece, while the rectangular clamping plate is positioned outside, allowing for clamping plate replacement. After replacement, the operator can release the pin, causing the first return spring to reset. Simultaneously, the pin can be pulled downwards, allowing the pin to... The clamping plate is embedded in the pin slot to fix its position. The structure of the movable rod and the pin post allows the operator to switch clamping plates simply by pulling the pin post upwards to disengage it from the pin slot and then rotating the rectangular clamping plate to the appropriate position. This greatly reduces the complexity and time consumption of manual operation. At the same time, the cooperation between the pin post and the pin slot ensures that the clamping plate is firmly fixed in the correct position after replacement, avoiding the risk of clamping plate loosening or shifting. This ensures the stability and safety of processing and solves the problem in the existing technology where, when encountering a cylindrical workpiece that needs to be clamped, the operator must manually replace it with an arc-shaped clamping plate. This process requires removing the original rectangular clamping plate and then installing an arc-shaped clamping plate suitable for the cylindrical workpiece.

[0022] 2. In use, after the clamping plates are fixed, the operator can place the cylindrical workpiece on top of the base plate and start the motor through the power supply system. During operation, the motor drives the output shaft to transmit power to the forward lead screw, which in turn drives the reverse lead screw. As the forward and reverse lead screws rotate, the slider slides relative to each other through the groove. The slider drives the support plate to move synchronously on top of the base plate. When the support plate moves, the movable rod and connecting piece drive the arc-shaped clamping plates to move synchronously relative to each other. The arc-shaped clamping plates then cause the soft pad to fit against the outer surface of the cylindrical workpiece, clamping and fixing it. The design of the forward lead screw and slider structure not only allows the slider to drive the clamping plates to move relative to each other to firmly fix the workpiece and prevent it from sliding or shifting during processing, thus improving processing safety, but also allows the operator to adjust the position of the slider to control the spacing between the clamping plates, making it suitable for workpieces of various specifications and improving the versatility of the fixture.

[0023] 3. In use, the electric telescopic rod in the base can be activated by the power supply system of the electric telescopic rod. When extended, it pushes the top of the first pushing block base to slide to the right, causing the first pushing block to slide synchronously at the bottom of the second pushing block. As the first pushing block slides, it pushes the second pushing block upward, which in turn pushes the base plate upward. This allows the base plate to slide upward on the outer surface of the connecting column, pulling the second return spring to extend. As the base plate rises, it can synchronously move the workpiece upward to compensate for the workpiece's height. Furthermore, the structure of the connecting column and the first pushing block allows the base plate to rise precisely as needed, thereby driving the workpiece to rise synchronously. This design can effectively compensate for height changes of the workpiece caused by variations during processing or other factors, maintaining the relative position of the workpiece and the processing equipment, and ensuring processing accuracy.

[0032] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0034] Please see Figure 1-7 This utility model provides a stable and efficient single-station clamp quick-change mechanism, comprising: a base plate 1, with support plates 101 movably connected to both sides of the top of the base plate 1, and two movable rods 102, both fixedly installed on the top of the support plates 101, with connecting members 103 movably sleeved on the outer surfaces of the two movable rods 102; two rectangular clamping plates 104, both fixedly installed on opposite sides of the two connecting members 103, with arc-shaped clamping plates 105 fixedly installed on opposite sides of the two connecting members 103; soft pads 106 are provided on the outer surfaces of the two rectangular clamping plates 104 and the two arc-shaped clamping plates 105; and two pin posts 107 are movably embedded on both sides of the interior of the two movable rods 102.

[0035] Furthermore, such as Figures 1 to 7 As shown, a first return spring 108 is fixedly installed on the top of each of the four pins 107. The four first return springs 108 are divided into two groups of two. Pin slots 109 are opened on both sides of the interior of the two connectors 103. The pins 107 can be pulled upward first, so that they can slide upward inside the movable rod 102 and drive the first return springs 108 to extend.

[0036] Furthermore, such as Figures 1 to 7As shown, the other ends of the two sets of first return springs 108 are fixedly installed on the top of the movable rod 102. The four pin slots 109 are matched with the pin post 107, so the pin post 107 can be released to reset the first return spring 108. At the same time as it resets, the pin post 107 can be pulled down, so that the pin post 107 can be embedded in the pin slot 109 to fix the position of the clamping plate.

[0037] Furthermore, such as Figures 1 to 7 As shown, a groove 2 is provided on the top of the base plate 1. A forward rotation screw 201 is movably embedded in the left side of the interior of the base plate 1, and a reverse rotation screw 202 is fixedly installed on the right side of the forward rotation screw 201. So when the motor 204 is running, it can drive the forward rotation screw 201 through the output shaft, and drive the reverse rotation screw 202 through the forward rotation screw 201.

[0038] Furthermore, such as Figures 1 to 7 As shown, the right outer surface of the reverse screw 202 is movably embedded in the inside right side of the base plate 1. Both the forward screw 201 and the reverse screw 202 are located inside the slide groove 2, which allows the forward screw 201 and the reverse screw 202 to rotate inside the slide groove 2.

[0039] Furthermore, such as Figures 1 to 7 As shown, both the forward-rotating lead screw 201 and the reverse-rotating lead screw 202 have sliders 203 threadedly connected to their outer surfaces. The tops of the two sliders 203 are fixedly installed on the bottom of the support plate 101, so the support plate 101 can be driven to move synchronously on the top of the base plate 1 by the sliders 203.

[0040] Furthermore, such as Figures 1 to 7 As shown, both sliders 203 are slidably connected inside the slide groove 2. A motor 204 is fixedly installed on the left side of the forward rotation screw 201. The bottom of the motor 204 is fixedly installed on the top left side of the base plate 1. So when the forward rotation screw 201 and the reverse rotation screw 202 rotate, the sliders 203 can be driven to slide relative to each other through the slide groove 2.

[0041] Furthermore, such as Figures 1 to 7 As shown, a base 3 is provided at the bottom of the base plate 1. Connecting posts 301 are fixedly installed around the top of the base 3. The four connecting posts 301 are movably embedded inside the base plate 1. Second return springs 302 are fixedly installed around the bottom of the base plate 1. The four second return springs 302 are movably sleeved on the outer surface of the connecting posts 301, so that the base plate 1 can slide upward on the outer surface of the connecting posts 301 and pull the second return springs 302 to extend.

[0042] Furthermore, such as Figures 1 to 7As shown, the other ends of the four second return springs 302 are all fixedly installed on the top of the base 3. An electric telescopic rod 303 is fixedly embedded in the left side of the interior of the base 3. A first push block 304 is fixedly installed on the other end of the electric telescopic rod 303. When the electric telescopic rod 303 extends, it can push the top of the base 3 to slide to the right, and make the first push block 304 slide synchronously at the bottom of the second push block 305.

[0043] Furthermore, such as Figures 1 to 7 As shown, the first push block 304 is slidably connected to the inner top side of the base 3, and the top of the first push block 304 is slidably connected to the second push block 305. The top of the second push block 305 is fixedly installed on the bottom of the base plate 1. So when the first push block 304 slides, the second push block 305 can be pushed upward, and the base plate 1 can be pushed upward by the second push block 305.

[0044] Working principle: In use, when it is necessary to clamp a cylindrical workpiece, the operator can first pull the pin 107 upward, allowing it to slide upward inside the movable rod 102, thus extending the first return spring 108. After it rises to a certain extent, it can disengage from the pin slot 109, and push the rectangular clamping plate 104 forward, causing the connecting member 103 to rotate on the outer surface of the movable rod 102. After the connecting member 103 rotates 180 degrees, the arc-shaped clamping plate 105 will be located inside the connecting member 103, while the rectangular clamping plate 104 will be located outside the connecting member 103, allowing for clamping plate replacement. After replacement, the operator can release the pin 107, allowing the first return spring 108 to extend. A reset spring 108 resets the clamping plate, and at the same time, it pulls the pin 107 down, so that the pin 107 can be inserted into the pin groove 109 to fix the position of the clamping plate. Through the structure of the movable rod 102 and the pin 107, the operator can switch the clamping plate by simply pulling the pin 107 upward to disengage it from the pin groove 109 and then pushing the rectangular clamping plate 104 to the appropriate position. This greatly reduces the complexity and time consumption of manual operation. At the same time, the cooperation between the pin 107 and the pin groove 109 ensures that the clamping plate can be firmly fixed in the correct position after replacement, avoiding the risk of the clamping plate loosening or shifting, and ensuring the stability and safety of processing.

[0045] In use, after the clamping plate is fixed, the operator can place the cylindrical workpiece on top of the base plate 1 and start the motor 204 through its power supply system. During operation, the motor 204 drives the output shaft to transmit power to the forward lead screw 201, which in turn drives the reverse lead screw 202. As the forward and reverse lead screws 201 and 202 rotate, they cause the slider 203 to slide relative to each other through the slide groove 2. The slider 203 also drives the support plate 101 to move synchronously on top of the base plate 1. When the support plate 101 moves, it can be connected to the connecting rod 102 via the movable rod. The receiving part 103 drives the arc-shaped clamping plate 105 to move synchronously relative to each other. In turn, the arc-shaped clamping plate 105 drives the soft pad 106 to fit against the outer surface of the cylindrical workpiece to clamp and fix it. Through the arrangement of the forward rotating lead screw 201 and the slider 203, not only can the slider 203 drive the clamping plate to move relative to each other to firmly fix the workpiece and prevent the workpiece from sliding or displacing during processing, thereby improving the safety of processing, but also the operator can adjust the position of the slider 203 to control the distance between the clamping plates to accommodate workpieces of various specifications, thereby improving the versatility of the fixture.

[0046] In use, the operator can activate the electric telescopic rod 303 via the power supply system of the electric telescopic rod 303 in the base 3. When it extends, the electric telescopic rod 303 pushes the top of the first push block 304 of the base 3 to slide to the right, causing the first push block 304 to slide synchronously at the bottom of the second push block 305. When the first push block 304 slides, it pushes the second push block 305 upward, and the second push block 305 pushes the base plate 1 upward. This allows the base plate 1 to slide upward on the outer surface of the connecting column 301 and pull the second return spring 302 to extend. When the base plate 1 rises, it can drive the workpiece to rise synchronously to compensate for the height of the workpiece. Through the structure of the connecting column 301 and the first push block 304, the base plate 1 can rise precisely as needed, thereby driving the workpiece to rise synchronously. This design can effectively compensate for the height changes of the workpiece caused by changes in the processing process or other factors, maintain the relative position of the workpiece and the processing equipment, and ensure processing accuracy.

[0047] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
