Description

Technical field:

[0001] The invention relates to the technical field of metal processing equipment, and more specifically to a left and right shock-absorbing tower machine processing clamping device. Background technology:

[0002] The shock tower is an important part of the vehicle's body structure. The shock tower is used to transfer the force exerted on the suspension to the vehicle body during the vehicle's driving.

[0003] The existing shock-absorbing tower is generally made of aluminum alloy high-pressure casting, and then machined to drill holes and other operations. It does not need to perform surface processing on the side panels. However, the cost of high-pressure casting is high. In order to reduce costs while ensuring strength, low-pressure casting is used for processing. However, the strength of low-pressure casting is lower than that of high-pressure casting, and the surface of the outer wall of the side panel of the shock-absorbing tower is worse than that of high-pressure casting, and the surface is not smooth enough. Therefore, it is necessary to perform milling processing on it later. However, since the side panel is a thin-walled portion, it cannot be clamped and fixed. After milling, the side panel is easily deformed, resulting in very poor processing accuracy and is not suitable for processing. At the same time, when the existing shock-absorbing tower is clamped, it does not have a positioning detection device, and it is impossible to confirm whether it is installed in place. Since the positioning position of the shock-absorbing tower is inside, when it is clamped, its inside faces downward, so it is impossible to check it manually, and it is easy to perform processing when it is not installed in place, thereby generating scrapped products, with poor effect and labor-intensive.

[0004] Meanwhile, the existing shock-absorbing tower generally includes a left shock-absorbing tower and a right shock-absorbing tower, and a general clamp can only clamp a single shock-absorbing tower, or shock-absorbing towers in the same direction, and cannot clamp a pair of shock-absorbing towers at a time, resulting in poor clamping effect. Summary of the invention:

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a left and right shock-absorbing tower machine processing clamping device, which can clamp a pair of shock-absorbing towers at a time, so that a pair of shock-absorbing towers can be clamped and processed at one time. At the same time, a vertical thickened portion and a side clamping cylinder are formed on the outer wall of the side plate on the outside of the shock-absorbing tower, which can clamp the side plate to facilitate the milling of the outer wall surface and ensure the processing accuracy. At the same time, the upper limit raised column and the airtight sensing column it has can detect the clamping position of the shock-absorbing tower to detect whether it is clamped in place without manual detection, thereby greatly improving its automatic processing effect and processing efficiency.

At this time, the pressure value of the pressure sensor fixed on the side wall of the pipeline at the outlet end of the high-pressure gas source will continue to rise. When it reaches the set value, it means that the shock tower 100 is placed correctly.

[0061] This structure allows the shock tower 100 to be clamped and fixed firmly.

[0062] At this time, the push rod of the clamping oil cylinder 302 pushes, and the push rods of all the upper clamping oil cylinders 22 push, so that the front end of the upper extension 305 of the upper end of the clamping block 304 and the bottom surface of the front end of the upper clamping block 23 are fixed to the wear-resistant and non-slip clamping block against the outer wall of the corresponding shock tower 100, and the clamping and fixing are achieved. At this time, the corresponding end of the corresponding sensing arm 309 is sensed by the top sensing part of the lower support column 1, indicating that it has moved into place and is clamped in place.

[0063] At the same time, the push rod of the side clamping cylinder 51 also pushes, so that the wear-resistant and non-slip clamping block fixed on the inner end face of the upper end of the side clamping block 52 is pressed against the outer wall of the vertical thickened portion 103, thereby fixing the corresponding position of its side plate. At this time, the shock tower 100 is firmly clamped.

[0064] Among them, since a vertical thickened portion 103 is formed in the middle of the lower part of the outer wall of the shock-absorbing tower 100 to be clamped, the strength of the corresponding side panel of the shock-absorbing tower 100 is increased, so that it is firmly fixed and not easy to deform during the processing, thereby ensuring the accuracy of the milling processing of its outer wall surface.

[0065] It can be processed after clamping, and the processing effect is good.

[0066] Two shock absorbing towers 100, one on the left and one on the right, can be processed at one time, that is, the processing of a pair of shock absorbing towers 100 is completed, and the processing efficiency is high and the effect is good.

[0067] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
