In the above process, due to the operation of manually placing the hub on the positioning table 3 directly below the down-pressing head 6, it is easy to be injured by the down-pressing of the down-pressing head 6 before the hand is withdrawn, resulting in a potential safety hazard. Summary of the Utility Model

[0005] The utility model aims to provide a down-pressing type hub bulging device to solve the problem that in the prior art, it is easy to cause hand injury due to manually placing the hub on the positioning table directly below the down-pressing head.

[0006] To achieve the above object, the utility model adopts the following technical solutions:

[0007] The utility model discloses a downward pressure type hub bulging device, which comprises: a base, a positioning table, a support frame, a downward pressure driving device and a downward pressure head. A positioning table is installed beside the base. The top of the positioning table is used to extend into the central ring of the hub. A support frame is fixed on the base, and a downward pressure driving device is installed on the support frame. The output end of the downward pressure driving device is connected to the downward pressure head, and the downward pressure driving device is used to drive the downward pressure head to move in the Y direction. The downward pressure type hub bulging device further comprises: a feeding linear driving device, a first guide rail, a sliding seat, a cushion block and a support reset device; A positioning seat protrudes from the center of the base. The top of the positioning seat is of a U-shaped structure, and the positioning table is placed at the opening of the positioning seat; The positioning table is fixed to the sliding seat, and the sliding seat can move relative to the first guide rail in the X direction. The first guide rail is installed beside the base. The sliding seat is connected to the output end of the feeding linear driving device. The end of the first guide rail close to the positioning seat is the working station, and the end of the first guide rail far from the positioning seat is the feeding station. The feeding linear driving device is used to drive the positioning table and the sliding seat to move between the working station and the feeding station; A support reset device is installed at the positioning seat, and the support reset device comprises: a moving seat, a pushing elastic member and a closing pushing mechanism. The moving seat is installed on the side of the positioning seat. There are two moving seats. The moving seat can move relative to the positioning seat in the Z direction. A cushion block is installed on the moving seat. A first notch is formed at the connection between the positioning table and the sliding seat, and the cushion block extends into the first notch. The bottom of the positioning table and the top of the cushion block are both used to support the conical ring and the edge ring of the hub located below the central ring. The two moving seats are connected by a pushing elastic member, and the pushing elastic member is used to push the cushion block on the moving seat away from the positioning table.

[0008] Preferably, the positioning seat is provided with a second notch for the moving seat to pass through.

[0009] Preferably, a second guide rail is installed on the positioning seat to guide the movement of the moving seat in the Z direction.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In this application, first, in order to avoid crushing hands, the sliding seat is designed to be fixed to the positioning table. The sliding seat moves under the guidance of the first guide rail. The positioning table and the sliding seat are driven by the feeding linear drive device to move back and forth between the loading station and the working station. The loading station is offset from the lower pressing head, thereby reducing the risk of the operator's hand being crushed and improving safety. Then, when the entire hub is expanded, there is no gap between the edge of the bottom of the hub and the surface of the sliding seat, and the hub is tightened by the positioning table. It is difficult to disassemble the expanded hub from the positioning table. Therefore, a first notch is opened at the connection between the positioning table and the sliding seat, so that when unloading, the hand can reach into the first notch and take out the hub from the first notch, which facilitates taking out the hub and improves the efficiency of taking out the hub. Finally, due to the opening of the first notch, when the lower pressing head presses down the hub, there is no support at the position corresponding to the first notch of the hub, and deformation is likely to occur. Therefore, a moving seat and a closing and pushing mechanism are provided to push the cushion block under the hub. When the lower pressing head presses down, the cushion block fills the position of the first notch, thereby preventing the hub from deforming at the first notch when the lower pressing head presses down.

[0016] Other advantages, objectives and features of the present utility model will be partially reflected by the following description, and partially will also be understood by those skilled in the art through the research and practice of the present utility model.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the technical means, creative features, achieved objectives and functions of the present utility model clearer and easier to understand, the present utility model will be further described below in conjunction with the drawings and specific embodiments:

[0023] As Figures 2 to 4 shown, the utility model discloses a down-pressing type hub expanding device, which includes: a base 2, a positioning table 3, a support frame 4, a down-pressing driving device 5 and a down-pressing head 6. A positioning table 3 is installed beside the base 2. The top of the positioning table 3 is used to extend into the central ring 11 of the hub. A support frame 4 is fixed on the base 2. A down-pressing driving device 5 is installed on the support frame 4. The output end of the down-pressing driving device 5 is connected to the down-pressing head 6. The down-pressing driving device 5 is used to drive the down-pressing head 6 to move in the Y direction. The down-pressing type hub expanding device further includes: a feeding linear driving device 7, a first guide rail 81, a sliding seat 82, a cushion block 30 and a support reset device 9; A positioning seat 20 protrudes from the center of the base 2. The top of the positioning seat 20 is of a U-shaped structure. The opening of the positioning seat 20 is for the positioning table 3 to be placed in; The positioning table 3 is fixed to the sliding seat 82. The sliding seat 82 can move relative to the first guide rail 81 in the X direction. The first guide rail 81 is installed beside the base 2. The sliding seat 82 is connected to the output end of the feeding linear driving device 7. The end of the first guide rail 81 close to the positioning seat 20 is the working station, and the end of the first guide rail 81 far from the positioning seat 20 is the loading station. The feeding linear driving device 7 is used to drive the positioning table 3 and the sliding seat 82 to move between the working station and the loading station; A support reset device 9 is installed at the positioning seat 20. The support reset device 9 includes: a moving seat 91, a pushing elastic member (not shown in the figure) and a closing and pushing mechanism 93. The moving seat 91 is installed on the side of the positioning seat 20. There are two moving seats 91. The moving seat 91 can move relative to the positioning seat 20 in the Z direction. A cushion block 30 is installed on the moving seat 91. A first notch is formed at the connection between the positioning table 3 and the sliding seat 82. The first notch is for the cushion block 30 to extend into. The bottom of the positioning table 3 and the top of the cushion block 30 are both used to support the conical ring 12 and the edge ring located below the central ring 11 in the hub. The two moving seats 91 are connected by a pushing elastic member. The pushing elastic member is used to push the cushion block 30 on the moving seat 91 away from the positioning table 3.

[0024] The working steps of the entire downward-pressing wheel hub bulging device are as follows: First, when the positioning table 3 is at the loading station, the worker loads the material and sets the wheel hub on the top of the positioning table 3. Since the inner diameters of both the conical ring 12 and the edge ring are larger than the top of the positioning table 3, the lower conical ring 12 and the edge ring can be easily set on the top of the positioning table 3. However, since the outer wall of the top of the positioning table 3 is in close contact with the central ring 11 of the wheel hub, it is very difficult to manually move the wheel hub into place and set it on the top of the positioning table 3. Achieving preliminary positioning is sufficient. Second, the feeding linear drive device 7 pushes the positioning table 3 and the wheel hub product directly below the downward pressure head 6, that is, to the working station. The positioning seat 20 supports the positioning table 3 through the support sliding seat 82. Third, the closing and pushing mechanism 93 pushes the two moving seats 91 closer to each other, and the cushion block 30 seals the first notch position, that is, the surface of the cushion block 30 is flush with the bottom surface of the positioning seat 20. Fourth, the downward pressure drive device 5 drives the downward pressure head 6 to press down. The downward pressure head 6 is of an annular structure. The downward pressure head 6 presses down on the root of the upper conical ring 12 and the central ring 11, pushing the entire wheel hub downward. The positioning table 3 bulges the central ring 11 of the wheel hub to prevent the central ring 11 of the wheel hub from not being a circular ring structure.

[0025] The positioning seat 20 is provided with a second notch for the moving seat 91 to pass through. The second notch ensures the movement of the moving seat 91.

[0026] A second guide rail (not shown in the figure) is installed on the positioning seat 20 to guide the movement of the moving seat 91 in the Z direction. Ensure that the moving seat 91 can move strictly in the Z direction.

[0027] The closing and pushing mechanism 93 includes: a pushing cylinder 931 and a pushing head 932. The pushing cylinder 931 is installed beside the base 2. The telescopic direction of the pushing cylinder 931 is in the X direction. The piston rod of the pushing cylinder 931 is fixed to the pushing head 932, and the pushing head 932 is used to push the two moving seats 91 closer to each other. The pushing head 932 of the pushing cylinder 931 pushes the two moving seats 91 closer to each other. Under the elastic force of the pushing elastic member, the two moving seats 91 and the cushion block 30 move away from each other and can move away to a position where they do not block the positioning table 3 from extending into the positioning seat 20.

[0028] The pushing head 932 is of a U-shaped structure. The pushing head 932 is provided with a pushing surface in contact with the moving seat 91. The moving seat 91 is provided with a squeezed surface in contact with the pushing head 932. The pushing surface and the squeezed surface are parallel, and the angle between the pushing surface and the X direction is an acute angle. The pushing surface squeezes the squeezed surface, so that the two moving seats 91 move closer to each other.

[0029] The pushing head 932 is supported by the supporting platform 933 below. Ensure that the pushing head 932 is always supported during the movement process to prevent the piston rod of the pushing cylinder 931 from being burdened by supporting the pushing head 932.

[0030] The feeding linear drive device 7 is an electric cylinder.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
