[0023] Hereinafter, embodiments of the present utility model will be described with reference to the accompanying drawings. In the following description, the same modules are represented by the same reference numerals. In the case of the same reference numerals, their names and functions are also the same. Therefore, the detailed description thereof will not be repeated.

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and do not constitute a limitation of the utility model.

[0025] like Figure 1-Figure 6 As shown, the multi-station clamping and unloading equipment for wheel rims provided by the embodiment of the utility model includes: a frame 1, a translation device 2, a clamping device 3 and a unloading device 4; the clamping device 3 is fixed on the translation device 2, and the translation device 2 is arranged on the frame 1. The clamping device 3 is used to clamp the rim 6, and the number of the clamping devices 3 is set according to the process to be completed by the rim 6, and is at least 2, and all the clamping devices 3 are arranged on the translation mechanism 2 at equal intervals.

[0026] The translation device 2 drives all the clamping devices 3 to move synchronously, thereby realizing the transmission of the rim between the mutual working stations.

[0027] In this paper, after the rim completes the last process, the position where the clamping device 3 is driven by the translation device 2 to move to the position according to the set distance is defined as the first preset position, i.e., the pre-unloading station; the position where the rim is unloaded to the delivery position is defined as the second preset position, i.e., the unloading station; and the height direction of the equipment is defined as the Y-axis direction.

[0028] In this embodiment, the number of clamping devices 3 is 5, corresponding to the processes of slag planing, rolling, end cutting, rounding of the rim and the pre-cutting station for extracting the rim position at the first preset position.

[0029] like Figure 2 As shown, the unloading device 4 is fixed on the frame 1, and the initial position of the unloading device 4 is located at the first preset position, and the unloading device 4 can reciprocate between the first preset position and the second preset position; when the rim is moved to the first preset position by the translation device 2, the unloading device 4 is in the initial position and extracts the rim, and when the unloading device 4 moves to the second preset position, the rim is unloaded, so that the rim is separated from the unloading device 4.

[0030] Therefore, by providing the unloading device 4, the automatic unloading of the rim is achieved.

[0031] Furthermore, the unloading device 4 includes a moving mechanism 41 and a unloading mechanism 42, the unloading mechanism 42 is fixed on the moving mechanism 41, and the moving mechanism 41 drives the unloading mechanism 42 to move the rim located at the first preset position to the second preset position; the unloading mechanism 42 is configured to extract the rim located at the first preset position, and unload the rim to the feeding position when it is at the second preset position.

[0032] Thus, the rim position is changed by setting the moving mechanism 41, and the rim is then sent to the feeding position.

[0033] Furthermore, the moving mechanism 41 includes a first cylinder 411, a connecting seat 412, a first guide rail 413, and a fixed seat 414. The fixed seat 414 includes a fixed base 415 and a connecting frame 416.

[0034] Therefore, the position movement is achieved by setting the first cylinder 411, which has a simple structure and saves costs.

[0035] Furthermore, the unloading mechanism 42 includes a fixing frame 421 and an executing component, the fixing frame 421 is fixedly connected to the connecting seat 412, the executing component is fixedly connected to the fixing frame 421, and the first cylinder 411 drives the executing component to move between the first preset position and the second preset position.

[0036] Furthermore, the actuator includes a second cylinder 422, a guide block 423, a fork 424 and an extraction rod 425.

The guide block 423 is fixed on the lower end face of the fixing frame 421; the extraction rod 425 cooperates with the guide block 423 and can move inside the guide block 425; the extraction rod 425 is hinged to the output end of the second cylinder 422 for extracting the rim 6; when the rim 6 is located at the second preset position, the fork 424 completes the unloading of the rim 6 through the movement of the second cylinder 422.

[0037] Furthermore, when the rim 6 is located at the first preset position, the second cylinder 422 drives the extraction rod 425 to be inserted into the rim 6 and abut against the inner wall of the rim 6; when the second cylinder drives the rim 6 to move to the second preset position, the second cylinder 422 drives the extraction rod 425 to move in the guide block until it is flush with the fork 424, and the fork 424 causes the rim 6 to be unloaded.

[0039] Furthermore, the unloading mechanism 42 also includes an adjusting rod 43.

In order to quickly adjust the position of the fork 424, a plurality of adjustment holes 426 are provided on the fork 424. The actual position of the fork 424 along the Y-axis direction is determined by the cooperation between the adjusting rod 43 and the adjusting hole 426.

[0040] In order to achieve the adjustability of the shift fork 424 in the Y-axis direction, the mounting hole of the shift fork 424 and the fixing frame 421 is designed as an elongated hole. When adjustment is required, the position of the mounting bolt in the elongated hole is adjusted.
