Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to an automatic tool setting device for machining mating keys. Background Technology

[0002] In the mechanical field, mating keys are common mechanical connecting elements, mainly used to achieve circumferential fixation between shafts and parts on the shaft, and to transmit motion and torque. They work by having the side of the key mate with the side of the shaft keyway and the hub keyway, enabling synchronous rotation of the shaft and its transmission components (such as gears and pulleys). Tool setting accuracy is crucial during mating key machining, ensuring the quality and precision of the key's machining. The purpose of tool setting is to determine the position of the program origin in the machine tool coordinate system. The tool setting point can be set on the workpiece, the fixture, or the machine tool. During tool setting, the tool setting point should coincide with the tool position point for better machining.

[0003] Manual tool setting requires aligning the tool tip with the center of the bar stock, which is time-consuming, labor-intensive, and time-consuming. Therefore, a tool setting device is added to the tool assembly shim to improve tool setting efficiency. For example, the utility model patent with authorization announcement number CN217224752U discloses an automatic tool setting device that uses an easily detachable infrared laser pointer attached to the shim for tool setting assistance, and adjusts the height of the light source to the height of the tool tip for easy tool setting. However, this device, as existing technology, has certain inconveniences in use. It cannot precisely control the height adjustment of the infrared laser pointer, and the rotational self-locking of the drive gear requires an additional structure. The installation stability of the drive box is poor, affecting its use. The drive box needs to have good installation stability and be easy to disassemble and assemble. Therefore, we designed an automatic tool setting device for key machining. Utility Model Content

[0004] The purpose of this invention is to provide an automatic tool setting device for machining mating keys, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic tool setting device for machining mating keys includes a shim and a drive box. One side of the shim has a mounting plate. The bottom of the drive box has two mounting blocks. The mounting plate has mounting grooves for the mounting blocks to be inserted into. A limiting component for fixing the mounting blocks is provided on the outer side of the mounting plate. A groove is formed at the center of the top of the drive box, and a corresponding lifting plate slides within the groove. A cavity is formed on the lower side of the drive box, and the groove communicates with the cavity. A threaded rod is rotatably provided at the center of the lower side wall of the cavity, with the other end of the threaded rod extending into the groove. A threaded hole matching the threaded rod is formed at the bottom of the lifting plate. A worm gear is rotatably provided between the left and right side walls of the cavity, and a worm wheel is fitted around the threaded rod, meshing with the worm gear. A scale line is provided on the outer surface of the lifting plate along the vertical direction. An assembly plate is provided on the top of the lifting plate, and an infrared laser pointer is inserted into the assembly plate.

[0007] As a preferred embodiment of this utility model: the limiting component includes two insert rods that are slidably inserted into the outer surface of the mounting plate, one end of each insert rod is inserted into a corresponding mounting groove, and the other ends of the two insert rods are connected to a pull plate. The outer surface of the mounting block is provided with a limiting socket for insert rods to be inserted, and a spring is sleeved on the outside of the insert rods.

[0008] As a further preferred embodiment of this utility model: one end of the worm gear is provided with a rotating shaft, and the other end of the rotating shaft extends through to the outside of the cavity and is connected to a rotating handle.

[0009] As a further preferred embodiment of this utility model: one end of the spring is connected to the outer surface of the mounting plate, and the other end is connected to the outer surface of the pulling plate.

[0010] As a further preferred embodiment of this utility model, a protrusion is provided at the top center of the pull plate.

[0011] As a further preferred embodiment of this utility model, the handle is rotatably mounted on the outer surface of the drive box.

[0012] As a further preferred embodiment of this utility model, the groove opening is a square structure.

[0013] The beneficial effects of this utility model are as follows: The protrusion in this device allows the operator to easily move the pull plate by hand, making it convenient to use. When the protrusion is moved outward, the pull plate and the insert rod move outward, so that the insert rod is no longer in the mounting slot. This allows the mounting block to be easily inserted into or removed from the mounting slot, which also facilitates the disassembly and assembly of the drive box, making it convenient to use. When it is necessary to adjust the height of the infrared laser pointer, rotating the handle drives the worm gear to rotate through the shaft, which in turn drives the worm wheel and the threaded rod to rotate. This allows the lifting plate to move vertically, and the height position of the infrared laser pointer can be quickly and accurately read through the scale lines on the outer surface of the lifting plate. In addition, the transmission cooperation of the worm wheel and worm gear and the threaded connection of the threaded rod make the height adjustment of the infrared laser pointer in this device self-locking, requiring no additional structure, making it simple to operate and providing good stability.

[0020] Please see Figure 1-3In this embodiment of the present invention, an automatic tool setting device for machining mating keys includes a gasket 1 and a drive box 16. A mounting plate 2 is provided on one side of the gasket 1. Two mounting blocks 11 are provided at the bottom of the drive box 16. The mounting plate 2 has mounting grooves 17 for the mounting blocks 11 to be inserted into. A limiting component for fixing the mounting blocks 11 is provided on the outer side of the mounting plate 2. A groove 8 is provided at the center of the top of the drive box 16. The groove 8 has a square opening. A corresponding lifting plate 6 is slidably disposed within the groove 8. A [missing information - likely a design feature] is provided on the lower interior side of the drive box 16. The cavity 9 is connected to the groove 8. A threaded rod 7 is rotatably provided at the center of the lower side wall of the cavity 9, and the other end of the threaded rod 7 extends into the groove 8. The bottom of the lifting plate 6 is provided with a threaded hole that matches the threaded rod 7. A worm gear 10 is rotatably provided between the left and right side walls of the cavity 9. A worm wheel 13 is sleeved on the outside of the threaded rod 7 and meshes with the worm gear 10. The outer surface of the lifting plate 6 is provided with a scale line 21 along the vertical direction. The top of the lifting plate 6 is provided with an assembly plate 4, and an infrared laser pointer 3 is inserted into the assembly plate 4.

[0022] The limiting assembly includes two insert rods 18 that are slidably inserted into the outer surface of the mounting plate 2. One end of each insert rod 18 is inserted into a corresponding mounting slot 17, and the other ends of the two insert rods 18 are connected to a pull plate 5. The outer surface of the mounting block 11 has a limiting insertion port 12 for inserting the insert rod 18. A spring 20 is sleeved on the outside of the insert rod 18.
