Description

Technical Field

[0001] This utility model belongs to the field of automotive synchronizer gear ring production and processing technology, specifically relating to an automotive synchronizer gear ring grinding device. Background Technology

[0002] In the manufacturing and processing of automotive synchronizer gear rings, grinding equipment is a key device for ensuring the precision of the gear ring tooth surface and reducing meshing noise. As a core component of gearbox shifting, synchronizer gear rings come in various specifications (different inner diameters, outer diameters, thicknesses, and number of teeth), and have extremely high requirements for tooth surface roughness and tooth profile precision, necessitating precise grinding to achieve the required performance. However, current traditional automotive synchronizer gear ring grinding equipment suffers from numerous structural design flaws, making it difficult to meet the demands of modern, efficient, and high-precision production.

[0003] Traditional grinding apparatus positioning structures have drawbacks: they rely on a single positioning method (such as simply fixing or clamping from the outside) and lack collaborative positioning logic. A single fixing method cannot withstand the radial force during grinding, making the toothed ring prone to displacement; a single clamping from the outside can lead to uneven force distribution due to unevenness on the outer wall of the toothed ring, causing loosening of the toothed ring in high-frequency vibration grinding scenarios and affecting grinding accuracy. Some apparatuses lack elastic buffering design, making it easy to damage the surface of the toothed ring during clamping. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed grinding device for automotive synchronizer gear rings in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A grinding device for automotive synchronizer gear rings includes a housing. A mounting base is fixedly installed on the bottom of the inner wall of the housing. Two sliding seats are slidably connected to the mounting base. A clamping fixing assembly is fixedly provided on one side of the top of the two sliding seats. A gear ring fitting adjustment assembly is slidably provided on the other side of the top of the two sliding seats. A connecting plate located below the gear ring fitting adjustment assembly is fixedly installed on the top of the two sliding seats. The clamping fixing assembly includes several clamps that cooperate with the sliding seats. An arc-shaped elastic clamp is fixedly installed at the other end of each clamp. The arc-shaped elastic clamps are arranged in a circumferential array. A grinding assembly is provided on the top of the inner wall of the housing, cooperating with the clamping fixing assembly and the gear ring fitting adjustment assembly.

[0007] As a further optimization of this utility model, a mounting bracket is fixedly installed on one side of the top of the sliding seat, a cylinder is fixedly installed on the side wall of the mounting bracket, a rotating disk is rotatably connected to the side wall of the cylinder, and a drive rod is connected to the output end of the cylinder, the drive rod slidingly penetrating through the side wall of the rotating disk.

[0008] As a further optimization of this utility model, the side wall of the rotating disk is equipped with a plurality of first U-shaped seats that cooperate with the grippers. The inner side wall of each first U-shaped seat is hinged to the corresponding gripper. The outer side wall of each gripper is hinged to a second U-shaped seat. The other ends of the plurality of second U-shaped seats are hinged to a hinge seat. One end of the drive rod is rotatably sleeved on the side wall of the hinge seat.

[0009] As a further optimization of this utility model, guide rails are fixedly installed on the top front and rear sides of the connecting plate, electric sliders are slidably connected to the top of the two guide rails, displacement adjustment seats are fixedly installed on the top of the two electric sliders, a first servo motor is fixedly installed on the top of the displacement adjustment seat, a toothed ring sleeve is fixedly connected to the output end of the first servo motor, and a limiting plate is fixedly sleeved on the side wall of the toothed ring sleeve.

[0010] As a further optimization of this utility model, the grinding assembly includes mounting blocks fixedly installed on both sides of the top inside the housing, a lead screw rotatably connecting the two mounting blocks, a slider threaded on the outer wall of the lead screw, a hydraulic cylinder fixedly installed at the bottom of the slider, and a grinding head fixedly installed at the output end of the hydraulic cylinder.

[0011] As a further optimization of this utility model, a second servo motor is fixedly installed on the side wall of any of the mounting blocks, and the output end of the second servo motor is fixedly connected to one end of the lead screw.

[0012] As a further optimization of this utility model, the top of the mounting base is provided with a sliding groove that cooperates with the sliding seat to slide, and the front side wall of the outer shell of the box is equipped with a box door.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, in the gripper fixing assembly, the cylinder drives the drive rod to move the hinge seat, and the second U-shaped seat pulls the gripper to rotate around the first U-shaped seat, so that the arc-shaped elastic clamp synchronously closes or opens, which can be adapted to toothed rings with different outer diameters; on the other hand, in the toothed ring sleeve adjustment assembly, the electric slider moves along the guide rail, which can adjust the relative distance between the toothed ring and the gripper fixing assembly, and adapt to toothed rings with different thicknesses; the toothed ring sleeve rod, together with the limiting plate, can be compatible with the sleeve requirements of toothed rings with different inner diameters.

[0015] 2. This utility model improves accuracy through "dual collaborative positioning": In the toothed ring sleeve adjustment assembly, the toothed ring sleeve rod and the limiting plate achieve initial axial and radial positioning of the toothed ring; the arc-shaped elastic clamp of the clamping claw fixing assembly clamps evenly from the outer wall of the toothed ring, forming a dual positioning of "inner sleeve + outer clamp"; the elastic design of the arc-shaped elastic clamp can buffer the clamping force, avoid damaging the surface of the toothed ring, and at the same time ensure that the clamping force is evenly distributed. The dual positioning structure can resist the radial and axial forces during grinding, prevent the toothed ring from shifting or loosening, and ensure the dimensional accuracy and surface quality of the toothed ring after grinding.

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1: As Figure 1 - Figure 3As shown, an automotive synchronizer gear ring grinding device includes a housing 1, which serves as the protective and load-bearing body of the device. A door 2 is installed on the front side wall of the housing 1, allowing for the removal and placement of the gear ring and equipment maintenance. A mounting base 3 is fixedly installed on the bottom of the inner side wall of the housing 1. A sliding groove 4 is provided on the top of the mounting base 3, and two sliding seats 5 are slidably connected in the sliding groove 4. The sliding seats 5 can move synchronously along the sliding groove 4 to adjust the relative position of the gear ring and the grinding assembly 13, adapting to different grinding process requirements.

[0024] like Figure 1 - Figure 4 As shown, the gripper fixing assembly 11 is installed on one side of the top of the two sliding seats 5 for precise clamping and positioning of the gear ring. Specifically, it includes: a mounting bracket 1101 is fixedly installed on one side of the top of each sliding seat 5; a cylinder 1102 is fixedly installed on the side wall of the mounting bracket 1101; a rotating disk 1103 is rotatably connected to the side wall of the cylinder 1102; and a drive rod 1108 is connected to the output end of the cylinder 1102. The drive rod 1108 slides through the side wall of the rotating disk 1103. It can move axially along the rotating disk 1103 as the cylinder 1102 extends and retracts. Several first U-shaped seats 1104 are evenly installed on the side wall of the rotating disk 1103. Each first U-shaped seat 1104 has a gripper 1105 hinged to its inner side wall. Each gripper 1105 also has a second U-shaped seat 1106 hinged to its outer side wall. The other end of all the second U-shaped seats 1106 is hinged to a hinge seat 1107. One end of the drive rod 1108 is rotatably sleeved on the side wall of the hinge seat 1107.

[0025] like Figure 1 - Figure 4 As shown, each gripper 1105 has an arc-shaped elastic clamp 1109 fixedly installed at the other end. Several arc-shaped elastic clamps 1109 are arranged in a circumferential array. When the cylinder 1102 pushes the drive rod 1108 to extend, the drive rod 1108 drives the hinge seat 1107 to move. Through the second U-shaped seat 1106, the gripper 1105 is pulled to rotate around the first U-shaped seat 1104, so that the arc-shaped elastic clamps 1109 synchronously converge towards the center and clamp the outer wall of the toothed ring. Conversely, when the cylinder 1102 retracts, the arc-shaped elastic clamps 1109 open, and the toothed ring can be removed.

[0026] like Figure 1 - Figure 3As shown, the gear ring fitting adjustment assembly is installed on the top of the two sliding seats 5 on the other side, and above the connecting plate 6. The connecting plate 6 is fixed to the top of the two sliding seats 5 and is used for axial positioning and specification adaptation of the gear ring. Specifically, it includes: guide rails 7 are fixedly installed on the front and rear sides of the top of the connecting plate 6, and an electric slider 14 is slidably connected to the top of the two guide rails 7. The electric slider 14 can move back and forth along the guide rails 7 to adjust the axial position of the gear ring; a first servo motor 9 is fixedly installed on the top of the electric slider 14. The output end of the first servo motor 9 is fixedly connected to a toothed ring sleeve 10. A limiting plate 12 is fixedly sleeved on the side wall of the toothed ring sleeve 10. In use, the toothed ring is sleeved on the outside of the toothed ring sleeve 10, with one end of the toothed ring abutting against the limiting plate 12 to achieve axial positioning. The first servo motor 9 can drive the toothed ring sleeve 10 to rotate the toothed ring, which, together with the grinding assembly 13, achieves uniform grinding in the circumferential direction of the toothed ring. The movement of the electric slider 14 can adjust the relative distance between the toothed ring and the gripper fixing assembly 11 to accommodate toothed rings of different thicknesses.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the grinding assembly 13 is installed on the top of the inner wall of the housing 1 and is used to grind the toothed ring after clamping and positioning. Specifically, it includes: mounting blocks 1301 fixedly installed on both sides of the top of the inner wall of the housing 1; a lead screw 1302 rotatably connected between the two mounting blocks 1301; sliding rods located on the front and rear sides of the lead screw 1302 fixedly installed between the two mounting blocks 1301; a second servo motor 1304 fixedly installed on the side wall of any mounting block 1301; the output end of the second servo motor 1304 is fixedly connected to one end of the lead screw 1302, which can drive the lead screw 1302 to rotate around its own axis. A slider 1303 is threaded onto the outer wall of the slide block 1303, which is slidably mounted on the outer wall of the two lead screws 1302. When the lead screws 1302 rotate, the slider 1303 can move axially along the lead screws 1302, and is supported by the two slide rods. A hydraulic cylinder 1305 is fixedly installed at the bottom of the slider 1303, and a grinding head 1306 is fixedly installed at the output end of the hydraulic cylinder 1305. The hydraulic cylinder 1305 can drive the grinding head 1306 to move up and down to adjust the grinding depth. When the second servo motor 1304 drives the slider 1303 to move, it can drive the grinding head 1306 to move axially along the tooth ring to achieve full tooth width grinding.

[0028] It should be noted that, when using this automotive synchronizer gear ring grinding device, the door 2 is opened, and the processing component is pulled out through the handle installed on the front side wall of the front sliding seat 5. Then, the gear ring to be ground is placed on the gear ring sleeve rod 10, so that one end of the gear ring abuts against the limiting plate 12. The electric slider 14 is started to adjust the gear ring to the corresponding position of the gripper fixing component 11. After the gear ring to be processed is installed, the processing component is pushed into the housing 1.

[0029] Gear ring clamping: Start cylinder 1102, drive rod 1108 pushes hinge seat 1107 to move, drive jaw 1105 to rotate through second U-shaped seat 1106, so that arc-shaped elastic clamp 1109 gathers and clamps the outer wall of gear ring.

[0030] Grinding adjustment: Start the second servo motor 1304 to drive the lead screw 1302 to rotate, which will move the slider 1303 and the grinding head 1306 to the position to be ground on the gear ring; start the hydraulic cylinder 1305 to adjust the grinding head 1306 to the appropriate grinding depth.

[0031] Grinding process: Start the first servo motor 9 to drive the gear ring sleeve 10 to rotate the gear ring; at the same time, the second servo motor 1304 drives the grinding head 1306 to move along the gear ring axis to complete the grinding of the gear ring; during the grinding process, the position of the gear ring can be adjusted to suit different grinding requirements by moving the sliding seat 5 along the sliding groove 4.

[0032] Part removal complete: After grinding, turn off all power sources, cylinder 1102 contracts to open the arc-shaped elastic clamp 1109, remove the toothed ring, and close the box door 2.

[0033] The above-described embodiments are merely examples of several implementations of this utility model. The descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
