Abstract

Technical Field
[0001] The utility model relates to the technical field of restraint tooling, in particular to a high-precision restraint tooling. Background Art
[0002] Thin-walled parts are components with relatively thin walls and are commonly used in the manufacturing industry. Due to their thin walls, these parts are usually lighter in weight, which helps reduce the weight of the overall system. Moreover, due to their extremely thin walls, thin-walled parts may be deformed during processing. Therefore, constraint tooling is required to fix the workpiece, making it less likely to deform during processing.
[0003] Most existing constraint tooling clamps thin-walled parts by using two large clamping plates to clamp the outer ends of the workpiece. However, simply applying pressure to the thin-walled parts from the outside can easily cause deformation of the thin-walled parts. Therefore, those skilled in the art have provided a high-precision constraint tooling to solve the problems raised in the above background technology. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a high-precision constraint tooling to clamp the workpiece stably and accurately.

[0009] Furthermore, placement grooves are provided on the upper sides of the end surfaces of the two side plates on one side opposite to each other, and the two outer arc plates are slidably arranged on the inner walls of the two placement grooves respectively.
[0010] Furthermore, outer cylinders are fixedly arranged between the three support mechanisms, and two outer cylinders are fixedly sleeved on the front and rear positions of the middle of the outer end surface of the shaft respectively.
[0011] Furthermore, circular grooves are provided on the upper end surfaces and lower end surfaces of the three support plates, and the plurality of buffer springs are fixedly arranged on the inner walls of the circular grooves.

The utility model proposes a high-precision constraint tooling, which sleeves the workpiece cylinder on the outer end of the shaft rod, and the buffer spring pushes the first inner arc plate to support the inner wall of the workpiece, thereby forming a preliminary fixed support for the workpiece, making it more convenient to clamp thinner workpieces, and the bamboo-jointed electric telescopic rod can be started to push the second inner arc plate, so that the second inner arc plate is pressed against the inner wall of the cylinder, which can clamp larger workpieces and clamp them more accurately, avoiding unstable clamping due to insufficient distance of the buffer spring.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] Reference Figure 1 、 Figure 2 、 Figure 3 The utility model provides an embodiment of a high-precision constraint tooling, comprising three support mechanisms 1, a base plate 11, a shaft 2 and a motor 12. A vertical plate 8 is fixedly provided at the middle position of the rear end surface of the base plate 11, and side plates 10 are fixedly provided on both sides of the middle position of the upper end surface of the base plate 11. A clamping electric telescopic rod 9 is fixedly provided at the middle position of the end surfaces on the opposite sides of the two side plates 10. An outer arc plate 5 is fixedly provided at the output end of the two clamping electric telescopic rods 9. Rollers 3 are rotatably provided on the end surfaces of the two outer arc plates 5 on the opposite sides.
[0025] A chassis 6 is fixedly set in the middle position of the front end face of the vertical plate 8, the shaft 2 is rotatably set in the middle position of the front end face of the chassis 6, a plurality of bolts 7 are set on the outer front end face of the chassis 6, the motor 12 is fixedly set in the middle position of the rear end face of the vertical plate 8, the output end of the motor 12 is fixedly set on the rear end face of the shaft 2, and the three supporting mechanisms 1 are respectively fixedly sleeved on the outer end faces of the shaft 2. The upper side positions of the end faces of the two side plates 10 on the opposite sides are provided with placement grooves 4, and the two outer arc plates 5 are respectively slidably set on the inner walls of the two placement grooves 4. An outer cylinder 13 is fixedly set between the three supporting mechanisms 1, and the two outer cylinders 13 are respectively fixedly sleeved on the front and rear positions in the middle of the outer end face of the shaft 2.
[0026] Specifically, when processing thin-walled parts, the cylinder is inserted into the outer end of the shaft 2, and the support mechanism 1 supports the cylinder to make the thin-walled parts more stably fixed. When encountering large workpieces, the clamping electric telescopic rod 9 is started to push the outer arc plate 5, so that the roller 3 inside the outer arc plate 5 is pressed on the outer end face of the cylinder to increase the stability of the clamping of the workpiece. Then the motor 12 is started to drive the shaft 2 to rotate. The rotating shaft 2 will drive the cylinder to rotate. The cylinder rotates on the inner wall of the outer arc plate 5, and the roller 3 assists the cylinder to rotate, avoiding friction between the workpiece surface and the inner wall of the outer arc plate 5. In addition, the clamping of the outer arc plate 5 makes the workpiece rotate more stably.
[0027] Reference Figure 4 The three supporting mechanisms 1 include three supporting plates 101, multiple first inner arc plates 105 and multiple bamboo electric telescopic rods 108. The multiple first inner arc plates 105 are fixedly provided with buffer springs 104 on the end surfaces close to the three supporting plates 101. The output ends of the multiple bamboo electric telescopic rods 108 are fixedly provided with second inner arc plates 107. The upper and lower end surfaces of the three supporting plates 101 are provided with circular grooves 103. Multiple buffer springs 104 are respectively fixedly provided on the inner walls of the circular grooves 103. Side grooves 102 are respectively provided in the middle positions of the end surfaces of both sides of the three supporting plates 101. Multiple bamboo electric telescopic rods 108 are respectively fixedly provided on the inner walls of the multiple side grooves 102. Inner grooves 106 are provided on the upper and lower sides in the middle of the end surfaces of both sides of the three supporting plates 101. Multiple second inner arc plates 107 are respectively slidably provided on the inner walls of the multiple inner grooves 106.
[0028] Specifically, the main body of the support mechanism 1 is a support disk 101, and a first inner arc plate 105 is arranged above the support disk 101. The first inner arc plate 105 is supported by a buffer spring 104, and the workpiece cylinder is sleeved on the outer end of the shaft rod 2. The buffer spring 104 pushes the first inner arc plate 105 to support the inner wall of the workpiece, thereby forming a preliminary fixed support for the workpiece, making it more convenient to clamp thinner workpieces, and lighter workpieces will not be rotated and thrown out after being clamped by the buffer spring 104. The bamboo-jointed electric telescopic rod 108 can be started to push the second inner arc plate 107, so that the second inner arc plate 107 is pressed against the inner wall of the cylinder, making the workpiece more stable. Moreover, the bamboo-jointed electric telescopic rod 108 pushes the second inner arc plate 107, so that larger workpieces can be clamped, avoiding the buffer spring 104 from having insufficient distance and unstable clamping.
[0029] Working principle: When processing thin-walled parts, the cylinder is inserted into the outer end of the shaft 2, and the support mechanism 1 supports the cylinder to make the thin-walled part fixed more stably. Then, the clamping electric telescopic rod 9 is started to push the outer arc plate 5, so that the roller 3 inside the outer arc plate 5 is pressed against the outer end surface of the cylinder. Then, the motor 12 is started to drive the shaft 2 to rotate. The rotating shaft 2 will drive the cylinder to rotate. The cylinder rotates on the inner wall of the outer arc plate 5, and the roller 3 assists the cylinder to rotate, making its rotation more stable.
[0030] Secondly, the main body of the support mechanism 1 is a support plate 101, and a first inner arc plate 105 is arranged above the support plate 101. The first inner arc plate 105 is supported by a buffer spring 104 to provide preliminary support for the cylinder, and then the bamboo-jointed electric telescopic rod 108 is started to push the second inner arc plate 107, so that the second inner arc plate 107 is pressed against the inner wall of the cylinder to stably support and fix the cylinder.
[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
