DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 The utility model provides an embodiment: an automobile sheet metal processing fixture, comprising:

[0023] A first clamping plate 1, a first clamping plate 14 is arranged on one side of the first clamping plate 1, and a second clamping plate 5 is connected to the upper side of the first clamping plate 14 through a threaded rod 6, a large pull ring 7 is rotatably engaged between the second clamping plate 5 and the first clamping plate 14, and the installation and positioning of the large pull ring 7 is achieved through the engagement connection between the first clamping plate 14 and the second clamping plate 5, so that it can be installed and engaged separately, and is not affected by the opening and closing of the first clamping plate 1 and the second clamping plate 2 when in use;

[0024] The second clamping plate 2 is slidably arranged above the first clamping plate 1, and a high-strength bolt 3 is passed through the first clamping plate 1 and the second clamping plate 2, and a nut 4 is connected to the outside of the high-strength bolt 3. A spring 8 is connected between the first clamping plate 1 and the second clamping plate 2, and the spring 8 is sleeved on the outside of the high-strength bolt 3. Through the setting of this structure, the second clamping plate 2 can slide independently and has a good limiting effect, thereby ensuring the stability of the first clamping plate 1 and the second clamping plate 2 being stretched apart.

[0025] Furthermore, a through hole adapted for the high-strength bolt 3 is opened on the first clamping plate 1, and a first guide ring 11 is provided on the top edge of the through hole, and a first conical tip surface 12 is provided at the clamping end of the first clamping plate 1. The setting of the first conical tip surface 12 improves its clamping bite force, and through high-frequency quenching, the overall wear resistance is higher.

[0026] Furthermore, the first clamping plate 1, the first guide ring 11, the first conical surface 12 and the first clamping plate 14 are an integrated structure, a guide groove 13 is provided at the vertical end of the first clamping plate 1, a guide block 22 is fixedly connected to the outer wall of the second clamping plate 2, and the guide block 22 is slidably inserted in the guide groove 13, and the height of the guide block 22 is half of the height of the second clamping plate 2. Through the sliding friction between the guide block 22 and the guide groove 13, the expansion of the first clamping plate 1 and the second clamping plate 2 has a good guiding effect, thereby improving the stability of its use.

[0027] Furthermore, a through hole adapted for the high-strength bolt 3 is opened on the second clamping plate 2, and a second guide ring 21 is provided at the bottom edge of the through hole, and a second conical tip surface 23 is provided at the clamping end of the second clamping plate 2. The second clamping plate 2, the second guide ring 21, the guide block 22 and the second conical tip surface 23 are an integrated structure, and the second guide ring 21 and the guide groove 13 are both sleeved with a spring 8 on the outside. Through the setting of the spring 8, it can play an auxiliary supporting role in the opening of the first clamping plate 1 and the second clamping plate 2, thereby saving a certain amount of manpower and further improving the convenience of using the device.

[0028] Furthermore, a threaded hole is provided on the upper surface of the first clamping plate 14, and a step-type positioning hole is provided on the second clamping plate 5 corresponding to the threaded hole of the first clamping plate 14, and a threaded rod 6 passes through the step-type positioning holes to the inside of the threaded hole. The first clamping plate 14 and the second clamping plate 5 are both provided with a rotation groove for the spherical structure of the big head pull ring 7 on the side close to each other. Through the separate engagement and positioning of the big head pull ring 7, its stability in use can be improved, and the situation where the big head pull ring 7 falls off due to the expansion of the traditional structure splint can be avoided.

[0029] Furthermore, the inner wall of the spring 8 is tangent to the outer wall of the first guide ring 11, the diameter of the first guide ring 11 is equal to the diameter of the second guide ring 21, and the heights of the first guide ring 11, the second guide ring 21, the second cone tip surface 23 and the first cone tip surface 12 are all equal.

[0030] Working principle: The high-strength bolts 3 and springs 8 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be repeated here. When the utility model is in use, the nut 4 is first loosened, and Genori makes the first clamp 1 and the second clamp 2 spread apart from each other under the elastic support of the spring 8, so that the processing part of the vehicle body can be clamped, and further by locking the high-strength bolts 3 and the nuts 4, the first clamp 1 and the second clamp 2 are squeezed together to complete the extrusion positioning of the vehicle body.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
