[0002] In mechanical engineering, various workpieces are processed. The most common workpiece is a cylinder. When processing the workpiece, the workpiece is mounted on a fixture. Most of the fixtures currently used are three-jaw fixtures, which clamp the workpiece so that it can be processed stably.

[0003] Since the three-jaw clamp clamps the outer ring of the workpiece, but the position of one end of the workpiece is not clamped, in actual operation, when the workpiece is clamped, it is easy for each clamping jaw to have different strengths, causing the workpiece to shift during the clamping process, making it impossible for the center line of the workpiece to coincide with the center line of the three jaws, thereby affecting the processing quality of the workpiece. Therefore, a clamp for mechanical engineering is proposed to solve the above problem. Utility Model Content

[0028] Example

[0029] Reference Figures 1-4 The utility model provides a technical solution: a clamp for mechanical engineering, comprising a mounting block 1 and a clamp mechanism 3, and a cylinder 2 is installed on the outside of the mounting block 1, the clamp mechanism 3 comprises a clamping rod 31, the clamping rod 31 is rotatably mounted inside the mounting block 1, and a round roller 311 is rotatably mounted on one end of the clamping rod 31, a push block 32 is mounted on the telescopic end of the cylinder 2, and an adjusting rod 321 is fixedly installed on the outer side of the push block 32, a conical block 33 is sleeved on the outside of the adjusting rod 321, and one end of the clamping rod 31 is in contact with the outer side of the conical block 33.

[0030] In a preferred embodiment, two clamping rods 31 are provided and are evenly arranged on the left and right sides of the mounting block 1. A rotatable first circular wheel 4 is installed at the bottom end of each clamping rod 31, and the first circular wheel 4 is connected to the outer side surface of the conical block 33 in a rolling manner. The device is provided with a first circular wheel 4 at one end of the clamping rod 31, and the first circular wheel 4 is rolled with the inclined surface of the conical block 33. In actual use, the conical block 33 is moved by moving the adjusting rod 321. During the movement of the conical block 33, the clamping rod 31 is pushed to rotate, thereby clamping the workpiece.

[0031] In a preferred embodiment, the interior of the mounting block 1 is set to be hollow, and a movable hole 5 is set on one side of the mounting block 1. The clamping rod 31 is set inside the movable hole 5 for rotating the clamping rod 31. In order to ensure the stable rotation of the clamping rod 31, the device provides a movable hole 5 on the mounting block 1, and the clamping rod 31 is set at the position of the movable hole 5 for use, which can leave a sufficiently large movable space for the clamping rod 31 so that the clamping rod 31 can be used normally to clamp the workpiece.

[0032] In a preferred embodiment, a second circular wheel 6 is fixedly installed on the upper end of the adjusting rod 321 for clamping the product. The adjusting rod 321 is arranged between the two clamping rods 31. The upper end of the adjusting rod 321 is provided with a second circular wheel 6, which can avoid clamping the workpiece and ensure the quality of the workpiece.

[0033] The present invention relates to a device for the production of air-conditioning system 1, wherein the air-conditioning system 10 is a kind of air-conditioning system of the present invention, and the air-conditioning system 10 is a kind of air-conditioning system of the present invention, and the air-conditioning system 10 is a kind of air-conditioning system of the present invention, and the air-conditioning system 10 is a kind of air-conditioning system of the present invention, and the air-conditioning system 10 is a kind of air-conditioning system of the present invention, and the air-conditioning system 10 is a kind of air-conditioning system of the present invention, and the air-conditioning system 10 is a kind of air-conditioning system of the present invention, and the air-conditioning system 10 is a kind of air-conditioning system of the present invention, and the air-conditioning system 10 is a kind of air-conditioning system of the present invention, and the air-conditioning system 10 is a kind of air-conditioning system of the present invention, and the air-conditioning system 10 is a kind of air-conditioning system of the present invention, and the air-conditioning system 10 is a kind of air-conditioning system of the present invention, and the air-conditioning system 10 is a kind of air-conditioning system of the present invention,

[0034] In actual use, in order to ensure that there are no impurities on the clamping rod 31, gas can be used to blow it to prevent the next workpiece from being clamped. Therefore, when controlling the movement of the adjusting rod 321, the device will also drive the piston rod 72 to slide inside the cylinder 71. At this time, the outside air will be sucked into the interior of the cylinder 71 through the air inlet pipe 10. When the adjusting rod 321 moves back, the piston rod 72 will move back inside the cylinder 71 and the gas inside the piston rod 72 will be pressed out. At this time, the gas will be ejected through the air outlet pipe 73 and blown on the outer surface of the clamping rod 31 to blow off impurities and avoid clamping subsequent workpieces. In addition, this device connects the cylinder 71 with the interior of the conical block 33 in a sliding manner.

[0035] Specifically, the working process or working principle of a mechanical engineering fixture is as follows: since the three-jaw fixture clamps the outer ring of the workpiece, but the position of one end of the workpiece is not clamped, in actual operation, when the workpiece is clamped, it is easy for the strength of each clamp to be different, causing the workpiece to shift during the clamping process, making it impossible for the center line of the workpiece to coincide with the center line of the three jaws, thereby affecting the processing quality of the workpiece. Therefore, this device is designed to solve this problem.

[0036] When the workpiece is clamped, the center line of the workpiece is in the middle of the clamping rod 31, thereby improving the processing quality of the workpiece. The specific operation is to connect the external power supply, place the workpiece between the two clamping rods 31, and turn on the cylinder 2 at the same time. The telescopic end of the cylinder 2 will push the push block 32 to move, and drive the adjusting rod 321 to move. When the adjusting rod 321 moves, the conical block 33 will be driven to move, and the position of the bottom end of the clamping rod 31 will contact the inclined surface of the conical block 33. The movement of the conical block 33 will push the clamping rod 31 to rotate and control the two clamping rods 31 to clamp the workpiece. At this time, the clamped state of the workpiece is tilted. As the adjusting rod 321 continues to move, one end of the adjusting rod 321 will come into contact with the outer surface of the workpiece, and the originally tilted workpiece can be pushed straight. With the cooperation of the two clamping rods 31 and one adjusting rod 321, the workpiece can be stably clamped.

[0037] While clamping the workpiece, the device can also ensure that the center line of the workpiece coincides with the center lines of the two clamping rods 31, ensuring that the workpiece is in a horizontal state, thereby facilitating external equipment to process the workpiece and improving the processing quality of the workpiece.

[0038] When the adjusting rod 321 moves back, the piston rod 72 will move back in the cylinder 71 and the gas inside the piston rod 72 will be squeezed out. At this time, the gas will be ejected through the outlet pipe 73 and blown to the outer surface of the clamping rod 31 to blow off the impurities and avoid clamping the subsequent workpieces.

[0039] In this way, after picking up the workpiece, the device will automatically blow air to the clamping rod 31, thereby improving the processing quality of the workpiece and facilitating use.

[0040] It should be noted that the cylinder 2 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.
