[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0030] Example 1

[0031] Reference Figure 1The present embodiment provides a fixing structure, including a clamping assembly 100, including a fixing base 101, on which a supporting base 102 and a positioning base 103 are provided, on which a positioning column 104 is fixedly connected, and on which an adjusting member 105 is inserted; a drilling assembly 200, including an operating table 201, on which a motor 202 is fixedly provided on the side wall, a pressure regulator 203 is provided on the top of the operating table 201, and a punching member 204 is movably connected inside the operating table 201.

[0032] Specifically, the clamping assembly 100 is a device for fixing the silencer pipe. The clamping assembly 100 can clamp the silencer pipe with a diameter within a certain range and has a wide range of applications. The fixed base 101 can fix the entire clamping assembly 100 to prevent the clamping assembly 100 from vibrating during punching and affecting the punching effect. The height of the support seat 102 is less than the height of the positioning seat 103. The positioning column 104 is above the support seat 102. The adjusting member 105 can be used to adjust the clamping diameter of the positioning column 104. The silencer pipe mounted on the positioning column 104 can be fixed simply by rotating the adjusting member 105.

[0033] Preferably, the drilling assembly 200 is a device for punching holes in the silencer pipe, the clamping assembly 100 is fixed on the operating table 201, and the clamping assembly 100 can change the fixed position at any time, which is convenient for drilling holes in different positions of the silencer pipe, and the motor 202 provides power for the punching member 204. The pressure regulator 203 on the top of the operating table 201 can observe the size of the power output by the motor 202 and adjust it to prevent the punching member 204 from being too slow or too fast and affecting the punching.

[0034] By setting up this device, not only can the silencer pipe be clamped, but also silencer pipes of different diameters can be clamped through the positioning column 104 with adjustable diameter, thereby increasing the application range of the device. At the same time, the punching operation driven by the motor 202 reduces the operation workload of the staff.

[0035] Example 2

[0036] Reference Figure 5, which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment, and is different from the previous embodiment in that: a plurality of countersunk holes 101a are provided on the fixed base 101; a groove 102a is provided on the support base 102, and a lifting platform 102b is provided in the groove 102a; a plug hole 104a is provided on the positioning column 104, a ratchet groove 104a-1 is provided at the front end of the plug hole 104a, a return spring 104a-2 is provided at the bottom of the plug hole 104a, an adjusting groove 104b is provided on the positioning column 104, a plurality of connecting columns 104b-1 are provided on the outer ring of the adjusting groove 104b, a plurality of rotating shafts 104b-2 are provided on the inner ring of the adjusting groove 104b, and a through positioning hole 104 is provided on the positioning column 104 4c; a rotating rod 106 is sleeved on the rotating shaft 104b-2, a driven tooth 106a is provided at one end of the rotating rod 106, a roller 106b is movably connected to the other end of the rotating rod 106, and the rotating shaft 104b-2 is connected to the driven tooth 106a; the adjusting member 105 includes a knob 105a and a rotating rod 105b, a ratchet 105b-1 is provided on the rotating rod 105b, the shape of the ratchet 105b-1 matches the shape of the ratchet groove 104a-1, a limiting rod 105c is provided below the ratchet 105b-1, a limiting block 105c-1 is symmetrically provided on the limiting rod 105c, an active tooth 105d is sleeved on the limiting rod 105c, and a limiting groove 105d-1 is symmetrically provided on the inner wall of the active tooth 105d.

[0037] Specifically, a bolt is inserted into the countersunk hole 101a, and the fixed base 101 is fixed to the operating table 201 by tightening the bolt. The lower half of the positioning column 104 is located in the groove 102a. The lifting platform 102b in the groove 102a can be adjusted up and down, and can support the bottom of the silencer to prevent the silencer from tilting during the punching process.

[0038] Preferably, the ratchet 105b-1 is made of a flexible material and can be deformed to a certain extent. At the same time, the thickness of the ratchet 105b-1 is consistent with the height of the ratchet groove 104a-1, the thickness of the active tooth 105d is consistent with the height of the adjustment groove 104b, and the active tooth 105d can be freely fixed on the limiting rod 105c. Through the cooperation of the limiting block 105c-1 and the limiting groove 105d-1, in addition to ensuring that the active tooth 105d does not rotate during the movement, it can also prevent the active tooth 105d from slipping when the adjusting member 105 is rotated.

[0039] Furthermore, the active tooth 105d is meshed with the driven tooth 106a, and the rotation of the rotating rod 106 can be achieved by rotating the adjusting member 105. The length of the rotating rod 106 is greater than the radius of the positioning column 104. Therefore, when the adjusting member 105 is rotated, the rotating rod 106 will gradually extend out of the adjusting groove 104b, and the length extended by the rotating rod 106 increases the clamping range of the positioning column 104.

[0040] In this embodiment, the silencer pipe to be punched is firstly sleeved on the positioning column 104, and then the adjusting member 105 is rotated to drive the rotating rod 106 to rotate through the cooperation of the active tooth 105d and the driven tooth 106a until the roller 106b at the outer end of the rotating rod 106 is in close contact with the inner wall of the silencer pipe, thereby completing the clamping of the silencer pipe. Since the rotating rod 106 is provided with the roller 106b, even if the rotating rod 106 rotates at an excessive angle and causes the roller 106b to rub against the inner wall of the silencer pipe, the silencer pipe will not be worn. The inner wall of the tube ensures the integrity of the silencer tube, and because of the cooperation between the ratchet 105b-1 and the ratchet groove 104a-1, the adjusting member 105 can only rotate in one direction and cannot be reversed. Therefore, in the absence of external force, the fixing of the rotating rod 106 can be guaranteed, thereby completing the initial fixation of the silencer tube; after the fixation is completed by rotating the adjusting member 105, continue to adjust the height of the lifting platform 102b to ensure that the lifting platform 102b is close to the bottom of the silencer tube to prevent the silencer tube from falling, thereby completing the secondary fixation of the silencer tube.

[0041] By providing the clamping assembly 100, the muffler pipe can be quickly fixed. At the same time, through the cooperation of the adjusting member 105 and the rotating rod 106, the clamping range of the positioning column 104 can be increased, thereby improving the applicability of the device.

[0044] Specifically, before punching, the position of the clamping assembly 100 installed on the fixing plate 201a is adjusted to ensure that the punching needle 204c and the positioning hole 104c are on the same axis to prevent damage to the positioning column 104 during punching.

[0045] Preferably, the power provided by the motor can be detected by the pressure detection gauge 203a, and can be adjusted at any time, thereby adjusting the punching speed of the punching member 204.

[0046] Furthermore, the auxiliary rods 204b provided on both sides enable the punching needle 204c to always move in the vertical direction, ensuring that the punched holes have the same shape. Furthermore, the punching needle 204c is detachable and can be replaced with punching needles of different diameters at any time to meet various punching requirements.
