Description

Technical Field

[0001] This utility model relates to the field of clamps, and in particular to a clamping device for cylindrical workpieces. Background Technology

[0002] Currently, in the cylindrical workpiece processing industry, after the cylindrical workpiece is completed on the production line, it is usually necessary to transfer the cylindrical workpiece to the next process for further processing. At this time, it is necessary to clamp the cylindrical workpiece with a clamping bracket, and then transfer the clamping bracket to the next process.

[0003] In existing technologies, the core component of clamping brackets is a three-jaw or multi-jaw chuck. When clamping cylindrical workpieces, the workpiece is clamped by synchronizing the movement of each jaw of the chuck. For example, Chinese utility model patent CN211540319U discloses a multi-degree-of-freedom clamping fixture for circular workpieces. However, the structure of three-jaw or multi-jaw chucks is relatively complex, resulting in high manufacturing costs for clamping brackets and making them unsuitable for large-scale deployment. Summary of the Invention

[0004] In view of the problem that the existing clamping devices for cylindrical workpieces have relatively complex structures, the purpose of this utility model is to provide a clamping device for cylindrical workpieces, so as to at least partially solve the above-mentioned problems.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A clamping device for a cylindrical workpiece includes a base plate, a fixed block, a movable block, and a clamping block; the base plate has an opening for the cylindrical workpiece to pass through; the fixed block is connected to one side of the top surface of the base plate, and there are two fixed blocks arranged on both sides of the opening along a first direction; the movable block is arranged between the two fixed blocks, and there are two movable blocks, both of which are slidably connected relative to the base plate along the first direction; each of the two fixed blocks is provided with an operating component for driving the movable block to move and locking its position.

[0007] In some preferred embodiments, a guide rod parallel to the first direction is connected between the two fixed blocks, and a corresponding guide hole adapted to the guide rod is opened on the movable block.

[0008] In some preferred embodiments, there are at least two guide rods arranged at intervals along a second direction, which is perpendicular to the first direction; the movable block has guide holes at both ends along the second direction.

[0009] In some preferred embodiments, the operating component is an operating rod threaded onto the fixed block, and the operating rod is parallel to the first direction.

[0010] In some preferred embodiments, the distal end of the operating lever is provided with a knob for turning.

[0011] In some preferred embodiments, V-shaped grooves are provided on the opposite sides of both clamping blocks.

[0012] In some preferred embodiments, the clamping block and the movable block, and the fixed block and the base plate are detachably fixedly connected by screws or bolts.

[0013] The beneficial effects of this utility model by adopting the above technical solution are as follows: This utility model has a significantly simpler structure than the prior art by setting up a fixed block, a movable block, a clamping block and an operating component. When in use, only the operating component needs to be turned to clamp the cylindrical workpiece through the clamping block. It can also adapt to cylindrical workpieces of various sizes and specifications, and has the characteristics of easy operation and wide applicability. Moreover, at least one operating component needs to be turned during operation. Attached Figure Description

[0022] A clamping device for cylindrical workpieces, such as Figure 1 and Figure 2 As shown, it includes a base plate 1, a fixed block 2, a movable block 3, and a clamping block 4.

[0023] The base plate 1 has a rectangular flat plate structure, and an opening 6, also rectangular, is provided on the base plate 1 for the cylindrical workpiece 5 to pass through. Two fixing blocks 2 are fixed to one side of the top surface of the base plate 1 by screws or bolts, and are arranged along a first direction on both sides of the opening 6. The first direction refers to... Figure 1 and Figure 2 The clamping device is positioned in the left and right directions. The fixing block 2 is elongated and arranged on the base plate 1 along a second direction, which is perpendicular to the first direction, and both the first and second directions are parallel to the base plate 1.

[0024] The movable block 3 is also elongated and parallel to the second direction. The movable block 3 is arranged between the two fixed blocks 2, that is, the movable block 3 is arranged across the opening 6 along the second direction. There are two movable blocks 3, and both movable blocks 3 are slidably connected relative to the base plate 1 along the first direction.

[0025] For example, a guide rod 7 parallel to the first direction is connected between two fixed blocks 2. Each fixed block 2 has a through hole adapted to the guide rod 7, and each fixed block 2 is equipped with screws or pins for fixing the guide rod 7. There are two guide rods 7, and they are spaced apart along the second direction. Correspondingly, each end of the movable block 3 along the second direction has a guide hole adapted to the guide rod 7. This arrangement allows both movable blocks 3 to slide relative to the base plate 1 along the first direction.

[0026] Each of the two fixed blocks 2 is equipped with an operating component 8 for moving and locking the movable block 3. The operating component 8 is configured as an operating rod threadedly connected to the fixed block 2. The operating rod is also parallel to the first direction. Thus, by turning the distal end of the operating rod, the operating rod can be driven to move axially, thereby pushing the two movable blocks 3 to move towards each other.

[0027] The distal end of the operating lever is equipped with a conveniently turned knob 9. The knob 9 is cylindrical and has a large diameter. Typically, the circumference of the knob 9 is embossed to increase friction. The movable block 3 is also usually provided with a blind hole that matches the proximal end of the operating lever, so as to support the proximal end of the operating lever and thus maintain the stability of the operating lever during use.

[0028] There are two clamping blocks 4, and each clamping block 4 is detachably fixed to two movable blocks 3 by screws or bolts. Each clamping block 4 has a V-shaped groove on its opposite side. In this way, when the two movable blocks 3 are close to each other, the cylindrical workpiece 5 can be clamped by the V-shaped grooves on the two clamping blocks 4.

[0029] like Figure 3 The diagram illustrates the process of using the clamping device provided by this invention to clamp a cylindrical workpiece 5. In use, first, the two operating components 8 are screwed away from each other, thus moving the two movable blocks 3 away from each other. Then, the cylindrical workpiece 5 to be clamped is inserted into the opening 6. Next, the left operating component 8 is screwed alone, causing the left movable block 3 to move to the right, thereby bringing its clamping block 4 into contact with the left side of the cylindrical workpiece 5, thus moving the cylindrical workpiece 5 to the right until it is clamped by the two clamping blocks 4. Alternatively, the right operating component 8 can be screwed alone, causing the right movable block 3 to move to the left, thus bringing its clamping block 4 into contact with the right side of the cylindrical workpiece 5, thus moving the cylindrical workpiece 5 to the left until it is clamped by the two clamping blocks 4. Alternatively, both operating components 8 can be screwed simultaneously, causing the two movable blocks 3 to move towards each other simultaneously until the cylindrical workpiece 5 is clamped by the two clamping blocks 4.

[0030] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is clear to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
