Description

Technical Field

[0001] This utility model relates to the field of milling technology for gearbox bodies, and in particular to a milling device for a high-torque tractor gearbox body. Background Technology

[0002] In the field of agricultural machinery, high-torque tractors are important power equipment, and their performance directly affects agricultural production efficiency. As a core component of the tractor's transmission system, the gearbox housing not only needs sufficient strength and rigidity to withstand high torque loads but also must meet lightweight design requirements to reduce overall energy consumption. Milling is a crucial process in the gearbox housing manufacturing process; good surface quality can effectively reduce friction loss, improve sealing performance, and extend service life.

[0003] Currently, the milling device for lightweight gearbox housings of high-torque tractors still has some shortcomings in use. For example, when milling the lightweight gearbox housing of a tractor, it can only perform single-sided milling operations, resulting in low milling efficiency and difficulty in meeting the needs of high-efficiency production.

[0004] In addition, during the workpiece fixing process, the existing device can only clamp the two sides of the lightweight gearbox body of the tractor, but cannot effectively limit the top. This may cause the gearbox body to vibrate up and down during the processing due to the lack of constraint at the top, which in turn affects the milling accuracy and quality.

[0005] To address this, a milling device for a high-torque tractor gearbox body is proposed. Utility Model Content

[0028] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0029] Please refer to Figures 1 to 3 As shown, this embodiment provides a milling device for a high-torque tractor gearbox body, including a base 2, milling components 1 for milling the surface of the tractor gearbox body are provided on both sides of the base 2, a feeding component is provided on the base 2, and a clamping fixture 4 is provided on the feeding component.

[0030] The clamping fixture 4 includes a bearing seat 401, a fixed seat 402 is fixedly installed at one end of the bearing seat 401, a first handle bolt 403 is rotatably installed on the fixed seat 402, and a first pressure plate 404 is rotatably installed at the end of the first handle bolt 403 away from its handle. The tractor gearbox body is fixed between the first pressure plate 404 and the inverted L-shaped limiting plate 405.

[0031] The other end of the bearing seat 401 is fixedly installed with an inverted L-shaped limiting plate 405. The top of the inverted L-shaped limiting plate 405 is rotatably threaded with a second handle bolt 407. The lower end of the second handle bolt 407 is rotatably installed with a second pressure plate 406 for limiting the top of the tractor gearbox.

[0032] Before milling, the tractor gearbox body is placed on the support seat 401. By manually rotating the first handle bolt 403, it moves forward, causing the first pressure plate 404, which is rotatably connected to it, to move towards the inverted L-shaped limiting plate 405, thereby clamping the gearbox body from both sides and restricting its horizontal movement. Then, rotating the second handle bolt 407 causes the second pressure plate 406 to descend, limiting the top of the gearbox body. Then, the feeding assembly moves the clamping fixture 4, transporting the fixed gearbox body to the milling assembly 1 on both sides, where the milling assembly 1 simultaneously mills both sides of the tractor gearbox body.

[0033] In this embodiment, the milling assembly 1 includes a base 101. An electric cylinder 105 and a first slide rail 106 are fixedly mounted on the top of the base 101. A first slider 107 is slidably mounted on the first slide rail 106. A gearbox 102 is fixedly mounted on the first slider 107. A first motor 103 is fixedly mounted on one end of the gearbox 102. The shaft of the first motor 103 is fixedly connected to the input end of the gearbox 102. A milling cutter 104 is fixedly mounted on the output end of the gearbox 102. The piston rod end of the electric cylinder 105 is fixedly connected to the bottom of the gearbox 102.

[0034] When milling is required on the gearbox housing, the first motor 103 is turned on, and its shaft begins to rotate. Since it is fixedly connected to the input end of the gearbox 102, it drives the gears inside the gearbox 102 to rotate. After speed change and torque conversion by the gearbox 102, the milling cutter 104 mounted on its output end rotates at high speed, thus polishing the surface of the gearbox housing. The piston rod of the electric cylinder 105 is controlled to extend and retract. When the piston rod extends, it pushes the gearbox 102, which is fixedly connected to it, moving it towards the tractor gearbox housing, causing the milling cutter 104 to mill the surface of the gearbox housing. When the piston rod of the electric cylinder 105 retracts, the gearbox 102 moves the milling cutter 104 away from the workpiece.

[0035] In this embodiment, the feeding assembly includes a second motor 3 and a connecting seat 302. Both the second motor 3 and the connecting seat 302 are fixedly mounted on the base 2. A lead screw 301 is rotatably mounted on the connecting seat 302. The end of the lead screw 301 away from the connecting seat 302 is fixedly connected to the rotating shaft of the second motor 3. A second slide rail 303 is fixedly mounted on the base 2. A second slider 304 is slidably mounted on the second slide rail 303. A movable seat 305 is fixedly mounted on the second slider 304. The movable seat 305 is threaded onto the lead screw 301. A bearing seat 401 is fixedly mounted on the movable seat 305.

[0036] In use, the second motor 3 is started, and the shaft of the second motor 3 drives the lead screw 301, which is fixedly connected to it, to rotate on the connecting seat 302. The rotation of the lead screw 301 causes the moving seat 305 to move linearly along the axis of the lead screw 301. This causes the tractor gearbox body, placed on the support seat 401, to move linearly back and forth on the base 2. When it is necessary to send the gearbox body to the milling assembly 1 for milling, the second motor 3 rotates forward, driving the moving seat 305 and the support seat 401 to move towards the milling assembly 1; after milling is completed, the second motor 3 reverses, driving them away from the milling assembly 1, thus realizing the functions of feeding and unloading.

[0037] In this embodiment, waste collection boxes 5 are provided on both sides of the support base 401, and the waste collection boxes 5 can be detachably installed on the movable base 305.

[0038] During the milling process of the milling assembly 1 on the tractor gearbox body, a large amount of waste such as debris is generated. As the support 401 moves on the base 2 along with the moving seat 305, the waste collection boxes 5 located on both sides of the support 401 also move, and their positions are just right to collect the waste material that has been ground off the surface of the gearbox body by the milling cutter 104.

[0039] Furthermore, positioning blocks 501 are fixedly connected to the bottom of both ends of the waste collection box 5, and positioning holes 3051 corresponding to the positioning blocks 501 are opened on the movable seat 305, and the positioning blocks 501 are inserted into the positioning holes 3051.

[0040] When installing the waste collection box 5 onto the movable base 305, align the positioning blocks 501 at the bottom of both ends of the waste collection box 5 with the pre-drilled positioning holes 3051 on the movable base 305, and then insert the positioning blocks 501 into the positioning holes 3051. The tight fit between the positioning blocks 501 and the positioning holes 3051 ensures the precise installation position of the waste collection box 5 on the movable base 305, guaranteeing the accuracy and stability of the waste collection box 5 installation.

[0041] To further improve the debris collection effect, guide ramps 4011 are provided on the top of both sides of the support base 401. Through the guide ramps 4011, the debris falling on the support base 401 can be guided into the waste collection box 5.

[0042] To facilitate the handling of the waste collection box 5, handles 502 are fixedly connected to both ends of the waste collection box 5.

[0043] Working principle:

[0044] Place the tractor gearbox body stably on the support seat 401 of the clamping fixture 4.

[0045] Manually rotate the first handle bolt 403 on the fixed base 402. Through threaded transmission, the first handle bolt 403 is pushed forward, causing the first pressure plate 404 to move toward the inverted L-shaped limit plate 405 until the first pressure plate 404 is in close contact with the gearbox body, clamping the gearbox body from both ends and restricting its movement in the horizontal direction.

[0046] Next, rotate the second handle bolt 407 on the top of the inverted L-shaped limiting plate 405, so that the second handle bolt 407 drives the second pressure plate 406 to descend until the second pressure plate 406 is in close contact with the top of the gearbox body, thereby limiting the top of the gearbox body.

[0047] Then the second motor 3 of the feeding assembly is started, and the shaft of the second motor 3 drives the lead screw 301 on the connecting seat 302 to start rotating.

[0048] Since the movable seat 305 is threadedly connected to the lead screw 301, and the second slider 304 slides on the second slide rail 303, the rotation of the lead screw 301 will cause the movable seat 305 to move linearly along the axis of the lead screw 301, thereby driving the bearing seat 401 and the tractor gearbox body fixed thereon to move towards the milling assembly 1.

[0049] When the first motor 103 is turned on, the shaft of the first motor 103 drives the gears inside the gearbox 102 to rotate. After the gearbox 102 changes speed and torque, it drives the milling cutter 104 installed at its output end to rotate at high speed.

[0050] Start the electric cylinder 105, control its piston rod to extend, push the gearbox 102 fixedly connected to it, so that the gearbox 102 moves towards the tractor gearbox body via the first slider 107 on the first slide rail 106 until the milling cutter 104 contacts the surface of the gearbox body, and the milling of the gearbox body surface begins.

[0051] During the milling process, the debris and other waste materials that are ground off the surface of the gearbox body by the milling cutter 104 are collected by the waste collection boxes 5 located on both sides of the support seat 401 as the support seat 401 moves. The guide ramps 4011 on the top of both sides of the support seat 401 guide the debris that falls on the support seat 401 into the waste collection boxes 5, thereby improving the waste collection efficiency.

[0052] After the milling operation on both sides of the gearbox body is completed, the second motor 3 of the feeding assembly is started to reverse, driving the moving seat 305 and the bearing seat 401 away from the milling assembly 1, and transporting the milled gearbox body to a position that is easy to unload.

[0053] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the present invention's conception through the foregoing teachings or related technical or knowledge.
