Description

Technical Field

[0001] This utility model relates to the field of guide wheel processing technology, specifically to the guide wheel processing center of Gaocheng New Machine. Background Technology

[0002] The guide roller in a high-precision wire EDM machine is a key component. Its main function is to guide and support the molybdenum wire, ensuring its stability and accuracy during machining. Guide rollers are typically made of high-quality materials, such as ceramics or special alloys, to ensure their wear resistance and durability.

[0003] During the production of alloy guide wheels, holes are typically drilled evenly on the sidewalls. These holes serve to reduce weight and rotational inertia, improve heat dissipation, and facilitate assembly and disassembly. In existing guide wheel drilling machining centers, the drilling tool is usually fixed in position, making it inconvenient to adjust the drilling position according to guide wheels of different radii. To protect the drilling tool, multiple sets of perforated grooves or a set of annular grooves are made on the support plate on the underside of the guide wheel. Multiple sets of perforated grooves limit the number of holes that can be drilled, while annular grooves do not limit the number of holes, but the bottom cannot be made to be continuous. Multiple connecting strips connect the support plates on the inner and outer sides of the grooves, which can easily restrict the scrap material and affect the material feeding.

[0004] To address the aforementioned technical issues, this application proposes a high-precision machining center for guide wheels. Utility Model Content

[0006] The technical problem this utility model aims to solve is that the position of the punching tool is usually fixed, making it inconvenient to adjust the punching position according to guide wheels of different radii. Multiple sets of hole-shaped grooves limit the number of holes that can be opened. Multiple sets of connecting strips connect the support plates on the inner and outer sides of the annular groove, and these connecting strips can easily restrict the waste material, affecting the material feeding.

[0007] II. Technical Solution

[0008] To solve the above technical problems, the technical solution provided by this utility model is: a high-precision measuring machine guide wheel machining center, including a machine box, a positioning frame and an inverted L-shaped frame. The positioning frame and the inverted L-shaped frame are installed on the top of the machine box. A support frame is connected between the lower side of the positioning frame and the machine box. The inverted L-shaped frame is installed on one side of the positioning frame.

[0009] Guide wheel positioning components are respectively installed on the opposite side walls of the positioning frame. A receiving block passes through the bottom of the positioning frame. A support pile is installed on the lower side of the receiving block. The lower end of the support pile is rotatably connected to the upper side of the chassis.

A position adjustment component is mounted on the eccentric side of the driven gear two. The position of the drilling head is adjusted by the position adjustment component. The receiving block is provided with a strip groove through which the drilling head passes.

[0011] A drive assembly is connected between the top plate of the inverted L-shaped frame and the chassis. The drive assembly, in conjunction with driven gear one and driven gear two, drives the punching head and the receiving block to rotate simultaneously.

[0012] As an improvement, the guide wheel positioning assembly includes a threaded shaft and a V-shaped clamping block. The V-shaped clamping block is located inside the positioning frame, and its outer wall is rotatably connected to the threaded shaft. The threaded shaft rotates through the side wall of the positioning frame and is connected by threads. Limiting rods are installed at both ends of the V-shaped clamping block.

[0017] III. Beneficial Effects

[0018] The advantages of this utility model compared with the prior art are as follows: the position of the punching head is adjusted by the position adjustment component, and when the driven gear rotates, the punching head is driven to punch guide wheels of different radii evenly. In addition, the tool groove is a strip-shaped tool groove. When the position of the punching head is adjusted, the movement range is within the inner side of the strip-shaped tool groove, which can effectively protect the punching head.

[0019] The drive assembly, in conjunction with driven gear one and driven gear two, drives the punching head and the receiving block to rotate simultaneously. The strip groove always corresponds to the punching head, and the strip groove does not limit the number of holes punched, nor does it obstruct the discharge of waste material.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] As attached Figure 2As shown, the high-precision new machine guide wheel machining center includes a chassis 1, a positioning frame 3, and an inverted L-shaped frame 11. The positioning frame 3 and the inverted L-shaped frame 11 are installed on the top of the chassis 1. A support frame 2 is connected between the lower side of the positioning frame 3 and the chassis 1. The inverted L-shaped frame 11 is installed on one side of the positioning frame 3. A control switch 24 is installed on the side wall of the inverted L-shaped frame 11. The electrical equipment of the machining center is controlled by the control switch 24.

[0029] To position the guide wheel, see attached... Figure 1 Appendix Figure 2 and attached Figure 4 As shown, a receiving block 9 passes through the bottom of the positioning frame 3. A shaft positioning block is threaded onto the upper side of the receiving block 9. The shaft positioning block is replaced according to the center mounting through hole of the guide wheel. The guide wheel is placed on the upper side of the receiving block 9, and the center mounting through hole is fitted onto the outer side of the shaft positioning block and fits against the outer side of the shaft positioning block to position the guide wheel shaft. A support pile 8 is installed on the lower side of the receiving block 9. The lower end of the support pile 8 is rotatably connected to the upper side of the housing 1. Guide wheel positioning assemblies are installed on opposite side walls of the positioning frame 3. The guide wheel positioning assembly includes a threaded shaft 5 and a V-shaped clamp 4. The V-shaped clamp 4 is located inside the positioning frame 3. Furthermore, the outer wall of the middle section is rotatably connected to the threaded shaft 5. The threaded shaft 5 rotates through the side wall of the positioning frame 3 and is connected by threads. The rotation of the threaded shaft 5 inside the positioning frame 3 drives the V-shaped clamping block 4 to move. Limiting rods 6 are installed at both ends of the V-shaped clamping block 4. The limiting rods 6 slide through the side wall of the positioning frame 3 and slide to limit the movement inside the positioning frame 3, preventing the V-shaped clamping block 4 from rotating with the threaded shaft 5. The outer wall of the guide wheel is clamped and positioned by the two sets of V-shaped clamping blocks 4. Anti-slip pads 7 are installed on the inner side of the V-shaped clamping blocks 4 to ensure that the guide wheel remains stable inside the two sets of V-shaped clamping blocks 4.

[0030] As attached Figure 2 and attached Figure 3 As shown, a driven gear 12 is rotatably mounted on the lower side of the top plate of the inverted L-shaped frame 11. An electric telescopic rod 16 is mounted below the eccentric part of the driven gear 12. The control switch 24 is connected to the electric telescopic rod 16, and the electric telescopic rod 16 is extended and retracted by the control switch 24. A motor 17 is mounted on the lower end of the electric telescopic rod 16. A punching head 18 is mounted on the shaft end of the motor 17. The electric telescopic rod 16 drives the punching head 18 to move up and down, and the motor 17 drives the punching head 18 to rotate, punching holes in the guide wheel. A spring-loaded discharge pusher is provided on the inner side of the punching head 18, which can push the waste material out from the inner side of the punching head 18.

[0031] The position of the punch head 18 can be adjusted, as shown in the attached figure. Figure 1 and attached Figure 2As shown, a position adjustment assembly is installed on the eccentric side of the driven gear 12. The position adjustment assembly includes a threaded shaft 14 and two sets of limiting blocks 15. The eccentric side of the driven gear 12 is provided with a strip-shaped slide 13 through which the threaded shaft 14 slides. One set of limiting blocks 15 is fixedly installed at the lower end of the threaded shaft 14, and the other set of limiting blocks 15 is sleeved on the upper outer side of the threaded shaft 14 and connected by threads. Depending on the drilling position, the threaded shaft 14 can move inside the strip-shaped slide 13. The upper set of limiting blocks 15 moves downward outside the threaded shaft 14. The two sets of limiting blocks 15 clamp the upper and lower sides of the driven gear 12 to fix the position of the drilling head 18.

[0032] The receiving block 9 is provided with a strip groove 19 through which the punching head 18 passes. When the position of the punching head 18 is adjusted, the punching head 18 is always located inside the strip groove 19. The strip groove 19 will not obstruct the discharge of waste material. A feeding trough 20 is installed on the lower side of the receiving block 9 and outside the strip groove 19. Waste material falls from the inside of the feeding trough 20 to the upper side of the machine box 1.

[0033] To ensure that the punching head 18 always aligns with the strip groove, as shown in the attached... Figure 3 and attached Figure 5 As shown, a driven gear 10 is installed on the lower outer side of the receiving block 9. A drive assembly is connected between the top plate of the inverted L-shaped frame 11 and the chassis 1. The drive assembly includes a rotating shaft 22 and two sets of driving gears 23. The upper and lower ends of the rotating shaft 22 are rotatably connected to the top plate of the inverted L-shaped frame 11 and the upper side of the chassis 1, respectively. The two sets of driving gears 23 are fixedly installed on the outer side of the rotating shaft 22. A protective cover 25 is installed on the outer side of the inverted L-shaped frame 11 to prevent objects from getting caught between the gears and affecting rotation. A motor 21 connected to the upper end of the rotating shaft 22 is installed on the upper side of the inverted L-shaped frame 11. The control... Switch 24 is connected to motor 21. By controlling switch 24, motor 21 is controlled. Motor 21 drives shaft 22 to rotate. Shaft 22 drives two sets of drive gears 23 to rotate. The two sets of drive gears 23 mesh with driven gear 10 and driven gear 22 respectively, which can drive driven gear 10 and driven gear 22 to rotate 360° back and forth. With the timed extension and retraction of electric telescopic rod 16, the punching head 18 punches holes at equal intervals on the guide wheel. At this time, the punching head 18 and the receiving block 9 rotate simultaneously. The strip groove 19 always corresponds to the punching head 18. The strip groove 19 does not limit the number of holes punched.
