Detailed Description
The embodiment of the utility model discloses a clamp for machining, as shown in fig. 1-4, comprising a support seat 1, a cavity is arranged in the support seat 1, a gear 107 is rotatably connected to the bottom of the cavity, a third rack 108 is meshed on the outer surface of the gear 107, a rotating component is arranged in the third rack 108, the third rack 108 is attached to the bottom of the cavity, a first chute 101 is arranged on the front side of the support seat 1, a second chute 102 is arranged on the back side of the support seat, the first chute 101 and the second chute 102 both penetrate through the support seat 1 and are communicated with the cavity, a first rack 103 is slidably connected to the inner wall of the first chute 101, a second rack 104 is slidably connected to the inner wall of the first chute 101, the first rack 103 and the second rack 104 are both meshed on the outer surface of the gear 107 and are symmetrically distributed on both sides of the gear 107, a first connecting block 105 is fixedly connected to the side of the first rack 103, a second connecting block 106 is fixedly connected to the side of the second rack 104, the front surface of the first connecting block 105 and the back surface of the second connecting block 106 are fixedly connected with a clamping block 109, so that workpieces with different sizes can be fixed, and the processing is convenient.
The first rack 103, the second rack 104 and the third rack 108 are not in the same horizontal plane, and the first rack 103 is above the third rack 108, and the second rack 104 is above the first rack 103.
The second connecting block 106 is longer than the first connecting block 105, and the two clamping blocks 109 are located on the same vertical plane, so that the two clamping blocks 109 are more effective in fixing the workpiece to be processed.
The rotating assembly comprises a threaded rod 201, the threaded rod 201 is in threaded connection with the inside of the third rack 108, one end of the threaded rod 201 is rotated to be connected with the side wall of the supporting seat 1, the side wall penetrating through the supporting seat 1 is fixedly connected with a rotating wheel 2 in an outward extending mode, a limiting groove 203 is formed in the supporting seat 1, a limiting block 202 is fixedly connected to the bottom of the threaded rod 201, and the limiting block 202 is connected to the inner wall of the limiting groove 203 in a sliding mode.
The cross sections of the limiting groove 203 and the limiting block 202 are both T-shaped, so that the movement of the third rack 108 is more stable.
The working principle is as follows: when workpieces with different sizes need to be machined and fixed, the workpiece to be machined is placed between the two clamping blocks 109, the rotating wheel 2 is rotated at the moment, the threaded rod 201 rotates along with the threaded rod 201, the limiting block 202 slides on the inner wall of the limiting groove 203 along with the rotation of the threaded rod 201 at the moment, so that the third rack 108 is driven to move, the third rack 108, the second rack 104 and the first rack 103 are all meshed with the gear 107, the gear 107 is driven to rotate along with the movement of the third rack 108 at the moment, so that the second rack 104 slides to the back of the supporting seat 1 along the inner wall of the second sliding groove 102, the first rack 103 slides to the front of the supporting seat 1 along the inner wall of the first sliding groove 101, and the first connecting block 105 and the second connecting block 106 move towards each other along with the sliding of the first rack 103 and the second rack 104, so that the two clamping blocks 109 move towards each other, along with the movement of the two clamping blocks 109, the workpiece to be processed is clamped and fixed, and at the moment, the workpiece can be fixed, so that the workpieces with different sizes can be fixed and processed.
When the workpiece needs to be taken down after the machining is completed, the rotating wheel 2 is rotated in the opposite direction, so that the first rack 103, the second rack 104 and the third rack 108 perform the above-mentioned opposite movements, and the two clamping blocks 109 are driven to move back to back, so that the workpiece can be taken out.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
