Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping device technology, specifically a multi-shell clamping device. Background Technology
[0002] A gripper is a mechanical device used to grasp, hold, or manipulate objects. It is widely used in industrial automation, robotics, manufacturing, and other fields. There are many types of grippers, including multi-shell grippers.
[0003] When using existing clamps, the workpiece is placed in the groove of the clamping seat, and then the outer clamping block clamps the workpiece pneumatically. However, after long-term use, the internal parts of the clamping seat at the bottom of the clamping block will wear out, causing the clamping block to move outward excessively due to uncontrolled stroke, and the clamping block may detach from the clamping seat. Therefore, it is necessary to propose a clamp with protection to prevent the clamping block from separating from the clamping seat. Utility Model Content
[0004] The purpose of this utility model is to provide a multi-shell clamp to solve the problems mentioned in the background section. To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0005] This utility model is a multi-shell clamp, comprising:
[0006] A clamping assembly, comprising a clamping base and clamping blocks; the clamping blocks are arranged in a set and slidably connected to the top of the clamping base at equal intervals;
[0007] The protective assembly includes a fixed rod, a placement groove, a spring, a movable rod, and a stop rod. The fixed rod is arranged in three sets, equidistantly fixed to the vertical surface of the clamping seat. Each set of fixed rods is located on both sides of the clamping block. The placement groove is opened inside the fixed rod. The spring is fixed to the inner end of the placement groove. The movable rod is slidably connected to the inner side of the placement groove, and the inner end of the movable rod is fixedly connected to the other end of the spring. The stop rod is located between the inner sides of the fixed rod.
[0008] Furthermore, a connecting rod is fixedly connected to one side of the outer end of the movable rod, and the outer end of the connecting rod is in close contact with the opposite end of the fixed rod.
[0009] Furthermore, a slot is provided on one side of the opposite end of the connecting rod, and a slider is slidably connected inside the slot.
[0010] Furthermore, the opposite ends of the slider are fixedly connected to both ends of the stop rod, and a soft pad is fixedly connected to one side of the stop rod.
[0011] Furthermore, the holding component also includes a groove; the groove is formed at the center of the top of the clamping seat and is located between the opposite ends of the clamping blocks.
[0012] Furthermore, it also includes anti-marking components;
[0013] The anti-marking component includes a vertical groove, a snap-fit rod, and an anti-slip pad; the vertical groove is opened above the opposite ends of the clamping block, the snap-fit rod is snapped into the inner side of the vertical groove, and the anti-slip pad is fixed to the outer end of the snap-fit rod.
[0014] Furthermore, side grooves are provided on both sides of the vertical groove, and magnetic rods are snapped into the inside of the side grooves. The magnetic rods and the side grooves are attracted by magnetic force, and the opposite ends of the magnetic rods are fixedly connected to the two sides of the snapping rods.
[0015] This utility model has the following beneficial effects:
[0016] This invention, by setting a protective component, ensures that when the clamping block moves excessively outward, it will abut against the stop bar. The impact force of the movement pushes the stop bar outward to a certain distance, and the stop bar drives the moving rod to move through the spring, thereby restricting the excessively outward-moving clamping block between the stop bar and the clamping seat, thus preventing the clamping block from detaching from the clamping seat and avoiding the loss of the clamping block.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0026] Please see Figures 1-3 As shown, this utility model is a multi-shell clamp, comprising:
[0027] The clamping assembly includes a clamping base 11 and clamping blocks 13; the clamping blocks 13 are arranged in a group and are equidistantly slidably connected to the top of the clamping base 11.
[0028] The holding component also includes a groove 12; the groove 12 is formed at the center of the top of the clamping seat 11 and is located between the opposite ends of the clamping blocks 13;
[0029] The clamping seat 11 is used to create the groove 12, which is used to place the workpiece, and the clamping block 13 limits the workpiece to be processed.
[0030] The protective assembly includes a fixed rod 21, a placement groove 22, a spring 23, a movable rod 24, and a stop bar 28. The fixed rod 21 is arranged in three sets and is fixed at equal intervals to the vertical surface of the clamping seat 11. Each set of fixed rods 21 is located on both sides of the clamping block 13. The placement groove 22 is opened inside the fixed rod 21. The spring 23 is fixed to the inner end of the placement groove 22. The movable rod 24 is slidably connected to the inner side of the placement groove 22, and the inner end of the movable rod 24 is fixedly connected to the other end of the spring 23. The stop bar 28 is located between the inner sides of the fixed rods 21.
[0031] The fixed rod 21 is used to open the placement groove 22, the placement groove 22 is used to connect the spring 23 and the movement of the moving rod 24, the spring 23 is used to limit the movement of the moving rod 24, the moving rod 24 is used to connect the connecting rod 25, and the stop rod 28 is used to limit the clamping block 13 from the outside.
[0032] A connecting rod 25 is fixedly connected to one side of the outer end of the movable rod 24, and the outer end of the connecting rod 25 is in close contact with the opposite end of the fixed rod 21;
[0033] A slot 26 is provided on one side of the opposite end of the connecting rod 25, and a slider 27 is slidably connected inside the slot 26.
[0034] The opposite ends of the slider 27 are fixedly connected to the two ends of the stop bar 28, and a soft pad 29 is fixedly connected to one side of the stop bar 28.
[0035] The connecting rod 25 is used to connect the moving rod 24 and the stop rod 28 and to open the slot 26. The slot 26 is used to connect and move the slider 27. At the same time, the stop rod 28 moves through the slider 27 and the slot 26. The soft pad 29 is used to protect the stop rod 28 and the outer end of the clamping block 13 to prevent the stop rod 28 from colliding with the clamping block 13.
[0036] Working principle: When the component is not in use, the clamping block 13 is located at the top of the clamping seat 11. When the clamping block 13 moves outward excessively, it will abut against the stop rod 28. The force of movement pushes the slider 27 to move in the slot 26 through the stop rod 28. The force pushes the stop rod 28 to move outward through the slider 27. When the stop rod 28 moves to a certain distance, the force of the stop rod 28 pushes the moving rod 24, causing the spring 23 to unfold, so that the moving rod 24 moves through the spring 23. When the moving rod 24 has completely moved outward through the spring 23, the excessively outward-moving clamping block 13 can be restricted between the stop rod 28 and the clamping seat 11, thereby preventing the clamping block 13 from detaching from the clamping seat 11.
[0037] Please see Figures 1-2 , Figure 4 As shown, this embodiment, based on the above embodiment, further includes:
[0038] Anti-marking components;
[0039] The anti-marking component includes a vertical groove 31, a snap-fit rod 32, and an anti-slip pad 33; the vertical groove 31 is opened above the opposite ends of the clamping block 13, the snap-fit rod 32 is snapped into the inner side of the vertical groove 31, and the anti-slip pad 33 is fixed to the outer end of the snap-fit rod 32.
[0040] The vertical groove 31 is used for the snap-fit rod 32, the snap-fit rod 32 is used for the connection of the anti-slip pad 33, and the anti-slip pad 33 is used to protect the opposite end of the clamping block 13 from the workpiece clamping point and prevent the clamping block 13 from leaving marks on the workpiece surface.
[0041] The vertical groove 31 has side grooves 34 on both sides. A magnetic rod 35 is snapped into the inside of the side groove 34. The magnetic rod 35 and the side groove 34 are attracted by magnetic force. The opposite ends of the magnetic rod 35 are fixedly connected to the two sides of the snapping rod 32.
[0042] The side groove 34 is used for connecting the magnetic rod 35. The magnetic rod 35 is attracted to the inside of the side groove 34 by magnetic force, thereby limiting the locking rod 32 after locking. At the same time, the anti-slip pad 33 can be replaced by pulling out the locking rod 32 by hand.
[0043] Working principle: When the component is not in use, the locking rod 32 is not inserted into the vertical slot 31. When the component is in use, hold the locking rod 32 by hand and insert it into the vertical slot 31. This causes the locking rod 32 to drive the magnetic rod 35 to be inserted into the side slot 34 at the same time. The magnetic rod 35 is attracted to the inside of the side slot 34 by magnetic force, thereby limiting the locking rod 32 after locking. When the opposite end of the clamping block 13 clamps the workpiece, the clamping block 13 drives the anti-slip pad 33 to clamp the workpiece, thereby preventing the clamping block 13 from leaving marks on the surface of the workpiece.
