Description

Technical Field

[0001] This invention relates to the field of clamping technology, and in particular to a clamp for bar stock and its method of use. Background Technology

[0002] In current bar stock production, depending on customer needs, bars often need to be fixed in a frame shape. During the fixing process, the bars need to be fixed by clamping devices, and then welded or bound.

[0003] Currently, clamping devices include a first clamping block, a second clamping block, and a driving component. The driving component drives the first and second clamping blocks to move relative to each other, clamping the bar stock. However, existing clamping devices can only clamp the bar stock. When changing to different specifications of bar stock, the contact surfaces (the middle seam of the overlapping area) of the two ends of the bar stock to be fixed cannot be guaranteed to always be in the same position, failing to meet the requirement of fixing it in the same position. Especially during welding, it is necessary to ensure that the welding area is kept on the same surface (the middle seam of the overlapping area) for welding the contact surfaces of the two ends, i.e., the middle seam of the overlapping area. Therefore, those skilled in the art need to design a fixture that can ensure that the middle seam between the workpieces is always in the same position. Summary of the Invention

[0004] To address the above problems, the present invention provides the following technical solution:

[0005] This invention provides a clamp for bar stock, the bar stock comprising a first single-strand region, an overlapping region, and a second single-strand region, including:

[0006] Two clamping members are used to clamp bar stock. Each clamping member includes a clamping member body and a protruding end. The two clamping member bodies are arranged opposite to each other and the two protruding ends are arranged on different sides.

[0007] A driving device is used to drive a clamping member to perform telescopic movement. The driving device includes a driving member and a guiding mechanism. The clamping member moves along the direction set by the guiding mechanism under the action of the driving member.

[0008] Two fixing blocks are used to fix the bar stock, which facilitates the clamping components to clamp the bar stock. The fixing blocks are set on one side of the two clamping components, and the planes on the opposite sides of the two fixing blocks are the same plane.

[0009] The pad is used to ensure that the center gap between the overlapping areas of the bar stock to be processed is always in the same position. Since the planes on the opposite sides of the two fixing blocks are the same plane, that is, the opposite sides of the fixing blocks are coplanar, when switching to bar stock of different diameters, the original pad is replaced with a pad of the same specification after the switch, so that the distance from the bar stock to be processed and the pad to the clamping part is the same, thus ensuring that the position of the center gap remains unchanged.

[0010] The protruding end is provided with a groove or through hole, and the pad is placed in the groove or through hole of the protruding end;

[0011] When clamped, the overlapping area of ​​the bar stock is located between the protruding ends of the two clamping members. The first single bar area and the second single bar area are located between the clamping body of one clamping member and the protruding end of the other clamping member, respectively, and are in close contact with them, so that the distance from the first single bar area and the second single bar area to the clamping body on the same side is the same as the distance from the pad bar to the other clamping body.

[0012] Preferably, the bar stock includes reinforcing bars, water pipes, and shafts.

[0013] Furthermore, the protruding end is located on the horizontal plane where the bottom, side, or top surface of the clamping body is located.

[0014] Furthermore, the diameter of the pad rod is the same as the diameter of the rod material.

[0015] Furthermore, the fixing block does not contact the clamping member on the same side.

[0016] Furthermore, when the clamp needs to be flipped, the pad can be made of iron, and a magnetic plate is provided on the clamping body on one side of the protruding end. The magnetic plate is used to attract the pad and prevent the clamp from falling off during the flipping process.

[0017] Furthermore, the guiding mechanism includes a guide post and a limiting block, the limiting block having a limiting hole, the guide post being placed in the limiting hole and fixedly connected to the clamping member.

[0018] Furthermore, the two clamping elements are driven by one or two drive elements.

[0019] Furthermore, the driving component drives the clamping component to perform linear motion.

[0020] Preferably, the driving component includes any one of a cylinder, electromagnet, hydraulic cylinder, electric cylinder, motor, linear motor, and cam mechanism.

[0021] This invention provides a method for using a clamp for bar stock, comprising the following steps:

[0022] Feeding: Place the overlapping areas of the bar stock to be processed between the two fixed blocks, and place the first single bar area and the second single bar area to be processed at the two fixed blocks;

[0023] Clamping: The driving component drives the clamping component to retract along the direction set by the guide mechanism, and the two clamping components move towards each other until the two clamping components clamp the bar material; the protruding end drives the pad bar to move under the drive of the driving component, so that the first single bar area and the second single bar area to be processed are in close contact with the pad bar and the clamping component respectively, restricting the position of the first single bar area and the second single bar area and preventing them from deviating from the center plane;

[0024] Machining: Machining the machining ends of the bar stock;

[0025] Unloading: The drive unit drives the clamping unit to return to its original position along the guide mechanism, releasing the processed bar stock, which then falls onto the support seat and is unloaded.

[0026] The present invention has the following beneficial effects:

[0027] (1) The present invention is provided with a fixing block and a pad. The opposite surfaces of the fixing block are coplanar. When switching to a bar of different diameters, the original pad is replaced with a pad of the same specification after the switch. This allows the overlapping area of ​​the bar to be located between the protruding ends of the two clamping members. The first single-root area and the second single-root area are respectively located between the clamping body of one clamping member and the protruding end of the other clamping member, and are in close contact with it. This makes the distance from the first single-root area and the second single-root area to the clamping body on the same side the same as the distance from the pad to the other clamping body. This ensures that the distance from the bar to be processed and the pad to the clamping member is the same, thereby ensuring that the position of the center seam remains unchanged.

[0028] (2) The clamping parts of the present invention are located on both sides of the bar stock. The overlapping area of ​​the bar stock to be processed is placed between the clamping parts, and there is nothing blocking it from above, which facilitates the next step of the operation on the bar stock.

[0029] (3) The pad of the present invention can be made of iron, and the clamping part is also provided with a magnetic plate to prevent the pad from falling off when the clamp is flipped.

[0030] (4) The fixture structure of the present invention is simple and can be used for processing large workpieces as well as small workpieces, with a wide range of applications. Attached Figure Description

[0040] The pad 4 is used to ensure that the center gap between the overlapping areas 52 of the bar stock to be processed is always in the same position. Since the planes on the opposite sides of the two fixing blocks 3 are the same plane, that is, the opposite sides of the fixing blocks 3 are coplanar, when switching to bar stock 5 of different diameters, the original pad 5 is replaced with the pad 5 of the same specification after the switch, so that the distance from the bar stock to be processed and the pad 4 to the clamping part is the same, thereby ensuring that the position of the center gap remains unchanged.

[0041] The protruding end 12 is provided with a groove or through hole 121, and the pad 4 is placed in the groove or through hole 121 of the protruding end 12.

[0043] Preferably, the bar stock 5 includes reinforcing bars, water pipes, and shafts.

[0044] In some preferred embodiments, the protruding end 12 is disposed on the horizontal plane where the bottom, side or top surface of the clamping body 11 is located.

The magnetic plate is used to attract the pad 4 and prevent the clamp from falling off during the flipping process.

[0048] In some preferred embodiments, the guiding mechanism 22 includes a guide post 221 and a limiting block 222. The limiting block 222 has a limiting hole, and the guide post 221 is placed in the limiting hole and fixedly connected to the clamping member 1.

[0049] In some preferred embodiments, the two clamping elements 1 are driven by one or two driving elements 21.

[0050] In some preferred embodiments, the driving member drives the clamping member to perform linear motion.

[0051] The driving component 21 includes any one of the following: cylinder, electromagnet, hydraulic cylinder, electric cylinder, motor, linear motor, and cam mechanism.

[0054] Clamping: The driving member 21 drives the clamping member 1 to retract along the direction set by the guide mechanism 22, and the two clamping members 1 move towards each other until the two clamping members 1 clamp the bar 5; the protruding end 12 drives the pad 5 to move under the drive of the driving member 21, so that the first single area 51 and the second single area 53 of the bar to be processed are in close contact with the pad 4 and the clamping member 1 respectively, restricting the position of the first single area 51 and the second single area 53 so as not to deviate from the center plane;

[0055] Machining: Machining the machining end of bar stock 5;

[0056] Unloading: The drive unit 21 drives the clamping unit 1 to return to its original position along the guide mechanism 22, releasing the processed bar stock 5. The bar stock 5 falls onto the support seat and is unloaded.
