[0019] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0020] like Figures 1-3As shown, a gearbox housing transfer device includes a base 1. Four support screws 22 are mounted on the top of the base 1 in a matrix arrangement. A base plate 2 is connected to each support screw 22. The base plate 2 has through holes for the support screws 22 to pass through. Two adjusting nuts 23 are mounted on each support screw 22, located on the upper and lower sides of the base plate 2 respectively. The mounting height of the base plate 2 on the base 1 can be finely adjusted by turning the adjusting nuts 23 to correspond to the height of the production line. Two supports are mounted on the base plate 2. The support frame 3 consists of two symmetrically distributed support frames 3. Several support rollers 4 are installed on the support frames 3 in a linear array along the length of the support frames 3. The support rollers 4 can rotate on the support frames 3. The support frame 3 also includes a transfer fixture for supporting and positioning the gearbox housing. The transfer fixture can move on the support rollers 4 to switch the gearbox housing between the base 1 and the production line. A positioning component is installed on the base 1 to position the transfer fixture on the base 1, preventing positional movement during transfer and improving the safety of the transfer.

[0021] like Figure 1 and Figure 2 As shown, traveling wheels 5 are installed at the four corners of the bottom of the base 1. The traveling wheels 5 are universal wheels with brakes, which can facilitate the movement of the base 1 between different production lines, realize the transfer of the gearbox housing, and brake the traveling wheels 5 after they are moved into place to fix the position and prevent movement during the transfer work and change of position, which could lead to safety accidents. A handrail 6 is installed on the side of the base 1 near the positioning component. The base 1 is moved by pushing it through the handrail 6, which improves the convenience of operation.

[0022] like Figures 1-3 As shown, the positioning assembly includes a positioning seat 7 and a positioning pin 8. The positioning seat 7 is fixedly installed on the base plate 2. The positioning pin 8 is installed inside the positioning seat 7 and can slide up and down along the axial direction of the positioning seat 7. A spring 9 is fitted on the positioning pin 8. One end of the spring 9 abuts against the positioning pin 8, and the other end of the spring 9 abuts against the positioning seat 7. The positioning pin 8 extends upward to the outside of the positioning seat 7 under the action of the spring 9. The top of the positioning pin 8 is machined with a first chamfer 10, and the bottom of the positioning pin 8 extends downward to the outside of the positioning seat 7. A connecting rod 13 is connected to the end of the positioning pin 8 located outside the positioning seat 7. One end of the connecting rod 13 is pivotally connected to the positioning pin 8. A hinge seat 11 is installed on the base 1. A handle 12 is pivotally connected to the hinge seat 11. The other end of the connecting rod 13 is hinged to the middle of the handle 12. By operating the handle 12, the positioning pin 8 can be pulled to overcome the elastic force of the spring 9, causing the positioning pin 8 to retract into the positioning seat 7.

[0023] like Figure 1 and Figure 2As shown, the transfer fixture includes a pallet 14, on which several positioning sleeves 15 are installed. The installation positions of the positioning sleeves 15 can be adjusted according to the different models of the gearbox housing to be transferred. Positioning pins 16, positioning diamond pins 17, and support rods 18 are respectively installed within the positioning sleeves 15. The positioning pins 16, positioning diamond pins 17, and support rods 18 are all threaded into the positioning sleeves 15, allowing adjustment of their relative installation height. The positioning pins 16, positioning diamond pins 17, and support rods 18 support and position the gearbox housing. A positioning block 19 is installed at the bottom of the pallet 14, with positioning holes 20 machined on it. The positioning holes 20 are adapted to the positioning pins 8. When the pallet 14 is moved into position, the positioning... Pin 8 is inserted into the positioning hole 20 to position the tray 14. A second chamfer 21 is machined on the side of the positioning block 19 facing the positioning component. The second chamfer 21 has the same specifications as the first chamfer 10. The tray 14 with the gearbox housing moves on the support roller 4. The positioning block 19 and the positioning pin 8 approach each other, and the first chamfer 10 and the second chamfer 21 abut against each other. The abutting force causes the first chamfer 10 of the positioning pin 8 to slide relative to the second chamfer 21. Overcoming the force of the spring 9, the positioning pin 8 retracts into the positioning seat 7. When the tray 14 moves to the point where the positioning pin 8 corresponds to the positioning hole 20, the positioning pin 8 extends out again and inserts into the positioning hole 20 under the action of the spring 9, and remains inserted in the positioning hole 20 under the action of the spring 9, thus completing the positioning of the tray 14.

[0024] like Figure 1 As shown, a T-shaped slot 24 is installed at the end of the base plate 2 away from the positioning component. Two centering blocks 25 are installed on the T-shaped slot 24. The two centering blocks 25 are spaced a certain distance apart, and the position of the centering blocks 25 on the T-shaped slot 24 is adjustable. A third chamfer 26 is machined on the side of the two centering blocks 25 that are close to each other. When the base 1 is pushed closer to the production line, the corresponding plug-in connection mechanism (not shown in the figure) on the production line can be plugged into the two centering blocks 25 to achieve positioning docking with the production line, ensure the accuracy of the position, and prevent the pallet 14 from falling off during the transfer process. The third chamfer 26 guides the plug-in.

[0025] The working principle of this utility model is as follows:

[0026] When the gearbox housing on the production line needs to be transferred to another location, the base 1 is moved to the end of the production line and closer to the production line by the handle 6, so that the plug-in connection mechanism on the production line is inserted between the two centering blocks 25 to complete the accurate docking of the base 1 and the production line. The manual operation handle 12 causes the positioning pin 8 to retract into the positioning seat 7 against the elastic force of the spring 9, releasing the plug-in connection between the positioning pin 8 and the positioning block 19, and pushing the pallet 14 to move towards the production line. The gearbox housing on the production line is lifted and placed on the pallet 14, supported by the support rod 18 and positioned by the positioning round pin 16 and the positioning diamond pin 17. After positioning, the pallet 14 is pulled along the support roller 4 to move away from the production line. The positioning hole 20 on the positioning block 19 is inserted into the positioning pin 8 to realize the positioning of the pallet 14, and the base 1 is pushed to move to the location to be transported.

[0027] When it is necessary to transfer the gearbox housing on the transfer fixture to the production line, move the base 1 to the end of the production line, insert the corresponding insertion connection mechanism on the production line between the two centering blocks 25, manually operate the handle 12 to make the positioning pin 8 retract into the positioning seat 7 against the elastic force of the spring 9, release the insertion of the positioning pin 8 and the positioning block 19, push the tray 14 to move towards the production line, and lift the gearbox housing on the tray 14 and place it on the production line.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made in accordance with the scope of the claims of this utility model should fall within the technical scope of this utility model.
