Description

Technical Field

[0001] This utility model relates to the technical field of accessories for CNC rotary gear chamfering machines, specifically a gear positioning and clamping structure for a CNC rotary gear chamfering machine. Background Technology

[0002] A CNC rotary gear chamfering machine is a device used to chamfer gears. It combines CNC technology with rotary machining principles. This type of machine tool is particularly suitable for mass production and is widely used in industries such as automotive gear processing, engineering machinery gear processing, speed reduction machinery gear processing, and machine manufacturing. The gear positioning and clamping structure is a core component of the CNC rotary gear chamfering machine.

[0003] A search revealed a gear chamfering clamping structure in a Chinese patent. This structure uses a downward-pressing transmission disc and pressure rod, which in turn drives the movement of an inner insert rod via a conical pressure block. This movement causes the stabilizing support legs to close. The gear to be chamfered is then fitted onto the outside of the clamping sleeve, and a tightening knob is rotated to limit and fix the gear. This increases the gear clamping speed and prevents other mechanisms from obstructing the clamped gear. However, because the outer diameter of the clamping sleeve is fixed, it can only support gears with a single inner diameter, making it difficult to position and clamp gears of different specifications. This affects versatility and limits its applicability. Therefore, we propose a gear positioning and clamping structure for a CNC rotary gear chamfering machine to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a gear positioning and clamping structure for a CNC rotary gear chamfering machine, 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] A gear positioning and clamping structure for a CNC rotary gear chamfering machine includes a sleeve body. A clamping table is fixedly connected to the right end of the sleeve body. A threaded portion is provided on the outer left end of the sleeve body, and a transmission sleeve is threaded onto the threaded portion. A limit pressure plate is fixedly connected to one end of the transmission sleeve. An annular groove is formed on the left end of the limit pressure plate. A positioning stud is rotatably connected to the sleeve body via a connecting seat. A slide block is threaded onto the outer side of the positioning stud. A guide groove is formed inside the sleeve body, and the slide block is slidably connected to the guide groove. Several support seats slide through the peripheral side of the sleeve body at equal intervals. A connecting rod is movably sleeved between the support seats and the slide block. Limit stops are fixedly installed on the support seats.

[0007] Preferably, a sealing block is fixedly installed at the inner left end of the sleeve body, and the positioning stud moves through the sealing block.

[0008] Preferably, a knob block is fixedly connected to the end of the positioning stud, and the cross-sectional shape of the knob block is a regular hexagon.

[0009] Preferably, the outer side of the transmission sleeve is provided with a plurality of levers, which are distributed in a ring at equal intervals.

[0010] Preferably, the side of the limiting block is provided with an anti-slip pad, which is a component made of rubber.

[0011] Preferably, a reinforcing ring is provided on the clamping platform, and the reinforcing ring is fixedly sleeved on the outside of the sleeve body.

[0012] Preferably, the end face of the clamping table is provided with a plurality of mounting holes, which are distributed in a ring at equal intervals.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes a knob block to rotate the positioning stud according to the inner diameter of the gear with a chamfered bevel, causing the slide block to slide along the guide groove inside the sleeve body. A connecting rod allows each support seat to slide synchronously along the sleeve body. The position of each support seat can be adjusted according to the inner diameter of the gear, thus supporting gears of various inner diameters. The gear is fitted onto each support seat, and a limiting block restricts and blocks the gear. A lever is used to rotate the transmission sleeve along the threaded portion on the left side of the sleeve body, causing the limiting pressure plate to move towards the gear. An annular groove effectively avoids the support seat until the limiting pressure plate and the limiting block cooperate to clamp the gear. This facilitates the positioning and clamping of gears of different specifications, improves the versatility of the positioning and clamping structure, and expands its application range.

[0023] As a preferred embodiment of this example, Figure 1 and Figure 2 As shown, a sealing block 104 is fixedly installed on the left end of the sleeve body 1. The positioning stud 5 moves through the sealing block 104. The sealing block 104 can seal the sleeve body 1 and provide auxiliary support for the positioning stud 5.

[0024] As a preferred embodiment of this example, Figure 1 As shown, a knob block 501 is fixedly connected to the end of the positioning stud 5. The cross-sectional shape of the knob block 501 is a regular hexagon, which facilitates the rotation of the positioning stud 5.

[0025] As a preferred embodiment of this example, Figure 1 As shown, the outer side of the transmission sleeve 3 is provided with several levers 301, which are distributed in a ring at equal intervals to facilitate the rotation of the transmission sleeve 3.

[0026] As a preferred embodiment of this example, Figure 2 and Figure 3 As shown, the side of the limit block 601 is provided with an anti-slip pad 602. The anti-slip pad 602 is a component made of rubber, which achieves the purpose of producing a good anti-slip effect on the gear.

[0027] As a preferred embodiment of this example, Figure 2 As shown, a reinforcing ring 201 is provided on the clamping platform 2. The reinforcing ring 201 is fixedly sleeved on the outside of the sleeve rod body 1 to improve the stability of the connection structure between the sleeve rod body 1 and the clamping platform 2.

[0028] As a preferred embodiment of this example, Figure 4 As shown, the end face of the clamping table 2 is provided with several mounting holes 202, which are distributed in a ring at equal intervals, so as to achieve the purpose of installing the clamping table 2 on the output end of the spindle box of the CNC gear chamfering machine.

[0029] Working principle:

[0030] During use, depending on the inner diameter of the gear 9 to be chamfered, the positioning stud 5 is rotated using the knob block 501, causing the slide block 7 to slide along the guide groove 103 inside the sleeve body 1. The connecting rod 8 allows each support seat 6 to slide synchronously along the sleeve body 1, enabling the position of each support seat 6 to be adjusted according to the inner diameter of the gear 9, thus supporting gears 9 with various inner diameters. The gear 9 is then fitted onto each support seat 6, and the limiting stop block 601 limits and blocks the gear 9. The lever 301 is used to rotate the transmission sleeve 3 in the forward direction along the threaded portion 101 on the left side of the sleeve body 1, causing the limiting pressure plate 4 to move towards the gear 9. The annular groove 401 effectively avoids the support seat 6 until the limiting pressure plate 4 and the limiting stop block 601 cooperate to clamp the gear 9. After the gear 9 is chamfered, the lever 301 is used to unscrew the transmission sleeve 3 in the reverse direction along the threaded portion 101 on the left side of the sleeve body 1, and then the chamfered gear 9 can be removed.
