[0002] Fixture tooling for machining, as a key component in modern mechanical manufacturing, its main function is to position and fix workpieces to ensure accuracy and stability during the machining process. They are widely used in machining, assembly lines, welding, assembly and other processes and are an indispensable part of the manufacturing industry. Fixture manufacturing is a comprehensive task involving multiple fields such as mechanical design, metal processing, and manufacturing processes.

[0003] Due to the smooth surface of circular tubular parts, traditional fixture tooling is difficult to provide stable clamping force, which may cause the parts to move or rotate during the machining process, thus affecting machining accuracy and product quality. Traditional fixture tooling may not be evenly distributed around the circular tube, resulting in uneven clamping force, which may cause stress concentration on the circular tube and may lead to deformation or damage of the circular tube. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0024] Refer to Figure 1 As shown, a new type of fixture tooling for mechanical processing includes a support pile 2. A table 1 is provided at the bottom of the support pile 2. An electric motor box 6 is provided above the support pile 2. An electric motor 11 is provided inside the electric motor box 6. A switch is provided above the electric motor box 6, and its input end is connected to the output end of the electric motor 11 by a circuit. The transmission shaft 12 of the electric motor 11 is fixedly connected to a threaded rod 5 located below it. When the electric motor is started, the transmission shaft 12 drives the threaded rod 5 to rotate. An adjustment opening is provided above the support pile 2, and the threaded rod 5 is located in the adjustment opening. The bottom end of the threaded rod 5 is rotatably installed on the bottom wall of the adjustment opening. A fixed tube 14 is threadedly sleeved on the bottom of the threaded rod 5. When the threaded rod 5 rotates, the fixed tube 14 will move up and down along the threaded rod 5 to achieve height adjustment. The other end of the fixed tube 14 extends away from the outside of the support pile 2. The other top end of the fixed tube 14 is fixed with a pull plate 4. The bottom of the pull plate 4 is rotatably connected to a scissors frame 3. The movement of the pull plate 4 will drive the opening or closing of the scissors frame 3, thereby controlling the clamping jaws 18;

[0025] The bottom of the scissors frame 3 is fixedly connected to the clamping jaws 18. Two fixed cylinders 7 are installed at the bottom of the clamping jaws 18. A sleeve 8 is slidably installed on one side of the fixed cylinder 7 close to the clamping jaws 18. A plurality of concentric annular grooves 19 are provided in the two sleeves 8, and the design allows the tubular workpiece to be easily inserted and fixed in the grooves. When the scissors frame 3 is closed, the clamping jaws 18 clamp the workpiece accordingly. When the scissors frame 3 is opened, the clamping jaws 18 release the workpiece.

[0026] Refer to Figure 1 and Figure 4 As shown, a new type of fixture tooling for mechanical processing, a slider 13 is fixedly installed on the fixed tube 14. The slider 13 is located in the adjustment opening inside the support pile 2. A vertical sliding opening is provided in the adjustment opening. The slider 13 is arranged in the sliding opening and can only slide vertically along the sliding opening. Due to the tight fit between the slider 13 and the sliding opening, when the electric motor 11 drives the threaded rod 5 to rotate, the fixed tube 14 and the slider 13 will move precisely vertically along the sliding opening together.

[0027] Refer to Figure 2As shown in the figure, a new type of fixture tooling for machining, the side surfaces of the sleeve 8 and the fixed cylinder 7 are respectively provided with a slide rail 10 and a chute 16. The slide rail 10 is designed on the outer side of the sleeve 8, and the chute 16 is designed on the inner side of the fixed cylinder 7. The sleeve 8 can horizontally move along the chute 16 in the fixed cylinder 7 through the slide rail 10. Threadedly connected to the side of the fixed cylinder 7 away from the clamping jaw 18 is an adjusting bolt 17. The other end of the adjusting bolt 17 is rotatably connected to the sleeve 8, and a bearing is provided at the connection. This design allows the adjusting bolt 17, when rotating, to drive the sleeve 8 to move through the action of the bearing. When the adjusting bolt 17 is rotated, it will push or pull the sleeve 8, thereby changing the horizontal position of the sleeve 8 in the fixed cylinder 7.

[0028] Refer to Figure 3 As shown in the figure, a fixing block 15 is fixedly installed inside the fixed cylinder 7. The fixing block 15 has a stepped structure, which can strengthen the connection strength between the fixing block 15 and the fixed cylinder 7, and a threaded hole that is threadedly engaged with the adjusting bolt 17 is provided at the central position. The threaded hole is used to receive and fix the adjusting bolt 17. When the adjusting bolt 17 rotates, it can move precisely along the direction of the threaded hole, and further control the precise adjustment of the sleeve 8 according to the length of the tubular workpiece to adapt to tubular workpieces of different lengths.

[0029] Refer to Figure 1 As shown in the figure, a new type of fixture tooling for machining, both the scissor lift 3 and the support pile 2 are made of stainless steel. In machining, the scissor lift 3 and the support pile 2 need to bear the weight of the workpiece and forces such as vibration and impact during the machining process. The stainless steel material can ensure its sufficient strength and durability to meet the usage requirements.

[0030] Refer to Figure 3 As shown in the figure, at the top of the end of the adjusting bolt 17 away from the fixed cylinder 7 is a rotating handle 9. The operator can easily drive the rotation of the adjusting bolt 17 through the rotating handle 9. The rotation angle of the adjusting bolt 17 can be precisely controlled through the rotating handle 9, thereby achieving precise control of the clamping force of the fixture tooling.

[0031] Working principle:

[0032] Step 1: When it is necessary to clamp a tubular workpiece, first insert the workpiece into the groove body 19 of the sleeve 8. By driving the rotation of the threaded rod 5 through the motor 11, the position of the fixed tube 14 on the threaded rod 5 can be conveniently adjusted, and then the lifting of the clamping jaw 18 is realized through the mechanism of the pull plate 4 and the scissor lift 3.

[0033] Step 2: When it is necessary to adjust the clamping length of the fixture tooling for the workpiece, the operator only needs to hold the rotating handle 9 and gently rotate it to drive the adjusting bolt 17 to rotate. Through the slide rail 10 and the chute 16, the sleeve 8 is pushed or pulled, so as to change the horizontal position of the sleeve 8 in the fixed cylinder 7, and thus different sizes and lengths of tubular workpieces can be adapted.
