Description

Technical Field

[0001] This application relates to the field of gearbox gear processing technology, and specifically discloses a tool holder for processing automotive gearbox gears. Background Technology

[0002] A car's transmission is a drive system that coordinates the engine speed and the actual speed of the wheels. It can change the transmission ratio between the engine and the wheels, allowing the engine to operate with optimal power performance.

[0003] Gearbox gears are mechanical components that transmit motion and power through continuous meshing of gears on their rims. During gear machining, a tool holder is used to hold the cutting tool before cutting. Current gearbox gear machining primarily relies on the movement of the tool holder. Existing tool holders are moved by a lead screw and slider pair controller, typically allowing only unidirectional movement and machining. This limited machining method is unsuitable for machining gears with inclined tooth grooves.

[0004] This invention provides a tool holder for machining automotive gearbox gears to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem that traditional gear processing tool holders can only process in one direction, making the processing method too limited and unsuitable for processing gears with inclined tooth grooves.

[0006] To achieve the above objectives, the basic solution of this utility model provides a tool holder for machining automotive gearbox gears, including a bracket, a guide frame 1 vertically disposed within the bracket, and a guide frame 2 horizontally disposed within the bracket. The bracket is provided with a control structure 1 for controlling the movement of the guide frame 2 along the guide frame 1. A base is horizontally slidably connected to the guide frame 2, and the guide frame 2 is provided with a control structure 2 for controlling the sliding of the base.

[0007] A drive box is rotatably connected to the base. The base is equipped with a control structure three for rotating the drive box. The drive box contains a gear reduction mechanism. The drive box is equipped with a drive motor one as the input of the gear reduction mechanism. The drive box is also equipped with a cutter head as the output of the gear reduction mechanism.

[0008] Both ends of the guide frame are equipped with water spray structures that face the cutter head.

[0009] Furthermore, the control structure one consists of a lead screw and slider pair one mounted on the support, and a drive motor two mounted on the support for driving the lead screw one of the lead screw and slider pair one to rotate. The lead screw one of the lead screw and slider pair one is vertically rotatably connected to the support, and the slider one of the lead screw and slider pair one is fixedly connected to one end of the guide frame two.

[0010] Furthermore, the second control structure consists of a lead screw and slider pair two mounted on the second guide frame, and a third drive motor mounted on the second guide frame for driving the lead screw and slider pair two to rotate. The lead screw and slider of the second lead screw and slider pair two are horizontally rotatably connected to the guide frame, and the slider of the second lead screw and slider pair two is fixedly connected to one side of the drive box.

[0011] Furthermore, the length of the lead screw in the second lead screw slider assembly is shorter than the length of the guide frame.

[0012] Furthermore, the top and bottom of both ends of the guide frame are respectively equipped with water spray structures facing the cutter head.

[0013] Furthermore, the water spray structure includes a screw fixed to both ends of the guide frame, a first nut and a second nut threaded onto the screw, a sleeve located on the screw between the first nut and the second nut, and a water spray head fixed to the end of the sleeve. The water spray head is connected to a water inlet pipe, and a rubber pad that abuts against the screw is provided inside the sleeve.

[0014] The principle and effect of this solution are as follows:

[0015] 1. Compared with the prior art, this utility model drives the cutter head and tool to rotate through drive motor one, and controls the lead screw slider pair one and lead screw slider pair two to move the guide frame two and the base through drive motor two and drive motor three, so as to move the tool to perform gear processing. At the same time, drive motor four can also rotate the direction of drive box, cutter head and tool to achieve multi-axis linkage, which can realize the processing of gears with inclined tooth grooves. This solves the problem that the traditional gear processing tool holder can only process in one direction, and the processing method is too simple and not suitable for processing gears with inclined tooth grooves.

[0016] 2. Compared with the prior art, this utility model can spray the processing positions on the front and back of the gear through four water spray heads, and discharge the waste generated during the processing into the water flow below. Because the water flow impact is continuous and fully covers the processing position, it can greatly reduce the probability of waste splashing and prevent processing accidents.

Each of the two guide plates 4 has a through hole vertically extending through it for the guide frame 1 to pass through.

[0024] The bracket houses a control structure for controlling the movement of guide frame two along guide frame one. Control structure one includes a lead screw-slider pair mounted on the bracket, and a drive motor mounted on the bracket to drive the lead screw 3 of the lead screw-slider pair one to rotate. Specifically, adapter plates are fixed on both support plates 1, the lead screw 3 is mounted between the two adapter plates 1 and is rotatable, the slider of the lead screw-slider pair one is fixedly mounted on the right end of guide frame two, and the output shaft of drive motor two is coaxially fixedly connected to the top end of lead screw 3 via a coupling.

[0025] A base 6 is also installed on the guide frame 2. The base 6 has two through holes for the support rod 2 5 to pass through, allowing the base 6 to slide along the support rod 2 5 on the guide frame 2. A control structure 2 for controlling the sliding of the base 6 is also installed on the guide frame 2. The control structure 2 includes a lead screw and slider assembly 2 installed on the guide frame 2, and a drive motor 3 installed on the guide frame 2 to drive the lead screw 2 9 of the lead screw and slider assembly 2 to rotate. Specifically, an adapter plate 2 is installed on the guide plate 4 on the right side. The lead screw 2 9 is mounted and rotatable through the adapter plate 2. The slider 2 of the lead screw and slider assembly 2 is fixed to the right side of the base 6, and the lead screw 2 9 passes through the slider 2. Simultaneously, the output shaft of the drive motor 3 is coaxially and fixedly connected to the top end of the lead screw 2 9 through a coupling. Furthermore, in this embodiment, the length of the lead screw 2 9 of the lead screw and slider assembly 2 is shorter than the length of the support rod 2 5.

[0026] like Figure 2 As shown, a rotatable drive box 7 is also installed on the base 6. A control structure three for rotating the drive box 7 is installed on the base 6. The control structure three includes a driven gear installed on the base 6 and connected to the rotation limit of the base 6, a drive motor four installed on the left side of the base 6, and a drive gear coaxially fixed to the output shaft of the drive motor four and meshing with the driven gear. The drive box 7 is fixed on the driven gear.

[0027] The drive box 7 is also equipped with a gear reduction mechanism. A drive motor is installed at the rear of the drive box 7 as the input of the gear reduction mechanism, and a cutter head 8 is installed at the front of the drive box 7 as the output of the gear reduction mechanism.

[0028] Furthermore, water spray structures facing the cutter head 8 are respectively mounted at both ends of the guide frame 2. Specifically, water spray structures facing the cutter head 8 are respectively mounted at the top and bottom ends of the guide plate 4. The water spray structure includes a screw 10 fixed on the guide plate 4, a nut 13 and a nut 2 threadedly connected to the screw 10, a sleeve 11 installed on the screw 10 between the nut 13 and the nut 2, and a water spray head 12 fixedly installed at the end of the sleeve 11. The water spray head 12 is connected to a water inlet pipe, and a rubber pad that abuts against the screw 10 is installed inside the sleeve 11, and the water spray head 12 is always facing the cutter head 8.

[0029] When using this utility model, first install a suitable cutting tool on the cutting head 8, then drive the cutting head 8 and the cutting tool to rotate through drive motor one, and control the lead screw slider pair one and lead screw slider pair two through drive motor two and drive motor three to move the guide frame two and the base 6, so as to move the cutting tool to perform gear processing. At the same time, the direction of drive box 7, cutting head 8 and cutting tool can also be rotated through drive motor four to realize multi-axis linkage, which can realize the processing of gears with inclined tooth grooves;

[0030] During gear processing, four water spray heads 12 can spray the processing positions on the front and back of the gear, and discharge the waste chips generated during processing into the water flow. Because the water flow is continuous and fully covers the processing position, it can greatly reduce the probability of waste chip splashing and prevent processing accidents.
