Description

Technical Field

[0001] This utility model belongs to the field of nut disassembly and assembly technology, specifically relating to a nut disassembly auxiliary tool. Background Technology

[0002] Wheel molds are typically cooled by air during casting to shorten the casting cycle. With technological advancements, water cooling has emerged as a highly efficient cooling method, gradually replacing air cooling systems and further improving the production efficiency of wheel casting.

[0003] The specific water cooling method involves assembling a five-hole water cooling kit on the existing wheel mold. The five-hole water cooling plate within the kit is welded inside the mold. The five-hole water cooling plate has five water injection pipes surrounding its outer circumference. These pipes are connected to the water supply pipes via five-hole water locking nuts, enabling water cooling of the five-hole water cooling plate. Due to the special nature of the wheel mold, the spacing between the five water injection pipes is very small, resulting in a narrow space for the five-hole water locking nuts (hereinafter referred to as nuts). When disassembling with a conventional wrench, it is difficult for employees to apply force. The small turning angle of the nuts requires repeated small-range tightening, which is difficult to apply force and prone to slippage, affecting the disassembly efficiency of the cooling plate. Forceful disassembly of the nuts can easily damage the five-hole cooling plate, affecting the service life of the five-hole water-cooled workpiece. Utility Model Content

[0004] This utility model provides a nut-assisted disassembly tool, which aims to solve the technical problems of time-consuming and labor-intensive disassembly of the five-hole water-locking nut of the water-cooled workpiece on the wheel mold and the small force application angle in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A tooling for assisting in the removal of nuts is provided, comprising:

[0007] The main body is disassembled and assembled, with a driving part at the top and a snap-fit ​​part at the bottom. The snap-fit ​​part has oppositely arranged snap-fit ​​arms, which enclose a snap-fit ​​space. One side of the snap-fit ​​space is open, and the snap-fit ​​space engages with the side of a nut.

[0008] A sleeve is provided on the drive unit. The top of the sleeve has a connecting groove, which is connected to the rotary drive component. The central axis of the connecting groove overlaps with the center of the snap-fit ​​space.

[0009] In one possible implementation, the disassembly / assembly body includes an integrally formed connecting block and an arc-shaped plate, the arc-shaped plate being disposed at the bottom of the connecting block, and the top of the connecting block forming the driving part; the bottom of the arc-shaped plate is provided with the snap-fit ​​arm.

[0010] In one possible implementation, the snap-fit ​​arm includes a first clamping arm and a second clamping arm connected in sequence. The first clamping arm is connected to the bottom of the arc-shaped plate, and the first clamping arm and the second clamping arm are set at an angle. The distance between the two second clamping arms gradually decreases in the direction away from the first clamping arm, and the distance between the two first clamping arms gradually increases in the direction closer to the second clamping arm.

[0011] In one possible implementation, a first surface is formed between the two first clamping arms, and the first surface, the inner walls of the two first clamping arms, and the inner walls of the two second clamping arms enclose the snap-fit ​​space, with the ends of the two second clamping arms spaced apart to form an opening in the snap-fit ​​space.

[0012] In one possible implementation, the thickness of the second clamping arm gradually decreases in the direction away from the first clamping arm.

[0013] In one possible implementation, a weight-reducing cavity is provided in the middle of the disassembly / assembly body, the weight-reducing cavity is connected to the snap-fit ​​space, and the size of the weight-reducing cavity on the axis of the disassembly / assembly body is larger than the size of the snap-fit ​​space.

[0014] In one possible implementation, the bottom surface of the snap-fit ​​arm is perpendicular to the axis of the disassembly / assembly body, and the bottom surface of the snap-fit ​​arm is provided with a wear-resistant layer.

[0015] In one possible implementation, the end of the second clamping arm is provided with a snap-fit ​​protrusion, and an opening of the snap-fit ​​space is formed between the two snap-fit ​​protrusions.

[0016] In one possible implementation, the connecting groove of the sleeve is a hexagonal groove.

[0017] In one possible implementation, the bottom inner edge of the snap-fit ​​arm is provided with a guide slope, which gradually slopes outward from top to bottom.

[0018] This utility model provides an auxiliary tooling for nut removal, which, compared with the prior art, offers a unique feature. The bottom of the main body for removal has a locking space that engages with and secures the nut. The operator operates the output end of the rotating drive component, which engages with the connecting slot. The rotating drive component drives the main body to rotate, which in turn rotates the nut, allowing it to be easily removed. The design of the main body eliminates the need for manual tightening of the nut with a wrench. The height of the main body raises the connecting space of the connecting slot, increasing the operable space and reducing the difficulty for the operator in connecting the rotating drive component and the connecting slot. This facilitates quick removal of the water-cooled nut from the wheel mold, improving removal efficiency. The locking space engages with the nut's side, changing the clamping from two sides to multiple sides, increasing the force application area on the nut. This reduces wear between the nut and the locking arm, extending the nut's service life. Attached Figure Description

[0034] Please refer to the following: Figures 1 to 4 The nut disassembly auxiliary fixture provided by this utility model will now be described. The nut disassembly auxiliary fixture includes a disassembly / removal body 1 and a sleeve 2; the top of the disassembly / removal body 1 forms a driving part, and the bottom of the disassembly / removal body 1 forms a snap-fit ​​part. The snap-fit ​​part has snap-fit ​​arms 13 arranged opposite to each other. The two snap-fit ​​arms 13 enclose a snap-fit ​​space 14. One side of the snap-fit ​​space 14 is open, and the snap-fit ​​space 14 snaps into the side of the nut; the sleeve 2 is located on the driving part. The top of the sleeve 2 has a connecting groove 21. The connecting groove 21 is connected to the rotating driving component, and the central axis of the connecting groove 21 overlaps with the center of the snap-fit ​​space 14.

[0035] It should be noted that the wheel mold has a groove on its top, and the five-hole water-cooling plate is located within this groove. The groove is cylindrical, and the five-hole water-cooling plate is welded into it. The five water injection pipes of the five-hole water-cooling plate are arranged around its axis on its upper surface. Five nuts are used to connect the water pipes of the water-cooling device. By tightening the nuts, the water injection pipes and water pipes on the five-hole water-cooling plate can be connected or disconnected. After the locking space 14 engages with the nut, the force applied from the side of the nut is changed to the axial force, altering the angle of force application for nut disassembly. The force is changed from applied from both sides of the wrench to multi-sided force application, increasing the single rotation angle of the nut and thus improving disassembly efficiency.

[0036] In practice, the snap-fit ​​space 14 is inserted into the nut from above, so that the snap-fit ​​arm 13 is fitted around the outer periphery of the nut.

[0037] It should be noted that the rotary drive can be a pneumatic gun or a rotary motor, as long as it has a rotatable drive end. After the drive end is inserted into the connecting groove 21, it is positioned at the upper limit in the circumference of the drive end. The rotation of the drive end drives the disassembly and assembly body 1 to rotate, thereby realizing the tightening and loosening of the nut.

[0038] It should be noted that the nut-assisted disassembly fixture provided in this embodiment can not only be used for disassembling the five-hole water-locking nut in the water-cooling fixture of wheel mold, but also for other environments involving nut disassembly. The nut-assisted disassembly fixture is used to transmit force and increase the convenience of nut disassembly.

[0039] Compared with the prior art, the nut-assisted disassembly fixture provided in this embodiment offers an auxiliary fixture. A snap-fit ​​space 14 is provided at the bottom of the disassembly / assembly body 1, which snaps and fixes the nut in place. The operator operates the output end of the rotary drive component, which snaps into the connecting groove 21. The rotary drive component rotates the disassembly / assembly body 1, which in turn rotates the nut, allowing it to be easily removed. The design of the disassembly / assembly body 1 eliminates the need for manual tightening of the nut with a wrench. The height of the disassembly / assembly body 1 raises the connecting space of the connecting groove 21, increasing the operable space and reducing the difficulty for the operator in connecting the rotary drive component and the connecting groove 21. This facilitates quick disassembly of the water-cooled nut on the wheel mold, improving disassembly efficiency. The snap-fit ​​space 14 snaps into the side of the nut, changing the clamping from two sides to multiple sides, increasing the force application area on the nut. This reduces wear between the nut and the snap-fit ​​arm 13, extending the nut's service life.

[0040] In some embodiments, see Figure 1 The assembly / disassembly body 1 includes an integrally formed connecting block 11 and an arc-shaped plate 12. The arc-shaped plate 12 is located at the bottom of the connecting block 11, and the top of the connecting block 11 forms a driving part. A snap-fit ​​arm 13 is provided at the bottom of the arc-shaped plate 12. The arc-shaped plate 12 does not obstruct the snap-fit ​​space 14, making it convenient for the snap-fit ​​space 14 to snap onto the nut. Furthermore, the arc-shaped plate 12 is lighter and less expensive than the ring, which can save processing costs, reduce the overall structural weight, reduce the labor intensity of workers, and make it easier for employees to grasp and hold the assembly / disassembly body 1.

[0041] In some embodiments, see Figure 4The locking arm 13 includes a first clamping arm 131 and a second clamping arm 132 connected in sequence. The first clamping arm 131 is connected to the bottom of the arc-shaped plate 12, and the first clamping arm 131 and the second clamping arm 132 are set at an angle. The distance between the two second clamping arms 132 gradually decreases away from the first clamping arm 131, and the distance between the two first clamping arms 131 gradually increases towards the second clamping arm 132. The first clamping arms 131 and the second clamping arms 132 enclose a locking space 14 that is adapted to the nut, preventing the nut from moving within the locking space 14, ensuring the locking effect of the nut, and increasing the locking area.

[0042] In some embodiments, see Figure 2 and Figure 4 A first surface 15 is formed between the two first clamping arms 131. The first surface 15, the inner walls of the two first clamping arms 131, and the inner walls of the two second clamping arms 132 enclose a locking space 14. The ends of the two second clamping arms 132 are spaced apart to form openings in the locking space 14. The first surface 15, together with the two first clamping arms 131 and the two second clamping arms 132, forms a hexagonal space that fits the nut. It abuts and limits the nut from five sides, increasing the force application area on the nut and reducing the strength of tightening the nut.

[0043] In some embodiments, the inner walls of the first surface 15, the two first clamping arms 131, and the two second clamping arms 132 are all coated with a protective layer to extend their service life.

[0044] In some embodiments, see Figure 4 The thickness of the second clamping arm 132 gradually decreases in the direction away from the first clamping arm 131. The gradual decrease in the thickness of the second clamping arm 132 can reduce weight, save costs, and increase ease of use.

[0045] In some embodiments, see Figure 3 The disassembly / assembly body 1 has a weight-reducing cavity 16 in the middle, which is connected to the snap-fit ​​space 14. The dimension of the weight-reducing cavity 16 on the axis of the disassembly / assembly body 1 is larger than that of the snap-fit ​​space 14. The weight-reducing cavity 16 can reduce the overall weight of the disassembly / assembly body 1, making it easier for employees to grip the disassembly / assembly body 1 at the position of the weight-reducing cavity 16, thus reducing the labor intensity of use.

[0046] In practice, the weight reduction cavity 16 is connected to the main body 1 at both ends and has an opening on one side.

[0047] In some embodiments, the bottom surface of the snap-fit ​​arm 13 is perpendicular to the axis of the disassembly / assembly body 1, and the bottom surface of the snap-fit ​​arm 13 is provided with a wear-resistant layer. The wear-resistant layer can reduce the impact damage to the nut and the snap-fit ​​space 14, and improve the protection effect on the snap-fit ​​arm 13.

[0048] In some embodiments, see Figure 4The end of the second clamping arm 132 is provided with a snap-fit ​​protrusion 133, and the two snap-fit ​​protrusions 133 form an opening of the snap-fit ​​space 14. The snap-fit ​​protrusion 133 can cooperate with the second clamping arm 132 and the first clamping arm 131 to form a hexagonal prism space, which is convenient for fitting with the nut.

[0049] In some embodiments, see Figure 1 The connecting groove 21 of the sleeve 2 is a hexagonal groove. The hexagonal groove facilitates connection with the output end of the rotary drive component, ensuring that the output end can normally drive the disassembly and assembly body 1 to rotate.

[0050] In some embodiments, the bottom inner edge of the snap-fit ​​arm 13 is provided with a guide slope, which gradually slopes outward from top to bottom. The guide slope can guide the nut to be inserted into the snap-fit ​​space 14, reducing the difficulty of insertion and improving the efficiency of nut disassembly.

[0051] In practice, the nut and the snap-fit ​​space 14 are inserted, the nut is turned 300°, the disassembly and assembly body 1 is removed, and the above operation is repeated to achieve quick disassembly of the nut, making it convenient to remove the water-cooled workpiece from the wheel mold.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
