[0011] Preferably, height positioning plates are also fixedly installed on both sides of the upper part of the lifting platform.

[0012] Preferably, the positioning plate can be movably matched and engaged with one side of the bottom battery box.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, the lifting platform installed on the outside of the base frame can position and lift the frame body. After lifting, the lifting column in the fixed cylinder driven by the lifting cylinder supports the frame body in the head tube at the front of the frame body. This allows for convenient, precise, and stable support and fixation of the frame body, enabling uniform painting of the frame body around its perimeter and top and bottom. Furthermore, moving the frame body via the lifting platform makes its fixation easier and more convenient.

[0015] 2.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a fixture for fixing and painting electric vehicle frames.

[0026] Example 1:

[0027] Combination Figure 1-4 As shown, the present invention provides a painting fixture for an electric vehicle frame, comprising: a base frame 100, a fixing component 200, and a frame body 300; the base frame 100 includes fixing holes 101 arranged at its bottom; the fixing component 200 includes a support platform 201 fixedly installed on the top of the base frame 100, a fixing cylinder 202 fixedly installed inside the support platform 201, a lifting column 203 movably installed inside the fixing cylinder 202, a lifting platform 204 fixedly installed on one side of the base frame 100, a mounting box 205 fixedly installed on the top of the lifting platform 204, fixing ears 206 fixedly installed on both sides of the mounting box 205, a positioning plate 207 fixedly installed between the fixing ears 206, and a clamping frame 208 movably installed on both sides of the mounting box 205; the frame body 300 includes a bottom... The bottom battery box 301, the frame tubes 302 on both sides, the head tube 303 at the front, and the hollow hole 304 inside the head tube 303 are all included. A double-headed cylinder 209 is also fixedly installed in the mounting box 205, and both ends of the double-headed cylinder 209 are fixedly connected to the clamping frame 208. Multiple sets of rollers 210 are also movably arranged in the mounting box 205. A lifting cylinder 211 is also fixedly installed at the bottom of the fixed cylinder 202, and the top of the lifting cylinder 211 is fixedly connected to the lifting column 203. A reinforcing plug 212 is also fixedly installed on the top of the lifting column 203, and the reinforcing plug 212 is movably matched and installed in the hollow hole 304. Height positioning plates 213 are also fixedly installed on both sides of the upper part of the lifting platform 204. The positioning plate 207 can be movably matched and locked onto one side of the bottom battery box 301.

[0028] Specifically, the electric vehicle frame painting fixture is a device for fixing the electric vehicle frame, thereby enabling comprehensive and even painting during the processing of the electric vehicle frame. In this fixture, a lifting platform 204 installed on the outer side of the base frame 100 can position and lift the frame body 300. After lifting, the lifting column 203 within the fixing cylinder 202, driven by the lifting cylinder 211, supports the frame body 300 within the head tube 303 at the front of the frame body 300. This provides convenient, precise, and stable support and fixation for the frame body 300, ensuring its smooth operation. The frame body 300 is uniformly painted all around and on both the top and bottom. The lifting platform 204 moves the frame body 300, making its fixation easier and more convenient. Simultaneously, the double-headed cylinder 209 inside the mounting box 205 at the top of the lifting platform 204, along with the clamping brackets 208 on both sides, can press and fix the frame body 300, positioned by the positioning plate 207 inside the mounting box 205, thus ensuring its stability during lifting. The fixing holes 101 on the base frame 100 are mainly used to fix the base frame 100 to the ground using screws and other components. The upper part of the base frame 100... The support platform 201 is mainly used to stably support the fixing cylinder 202, thereby supporting and fixing the frame body 300 through the lifting column 203 inside the fixing cylinder 202. The fixing cylinder 202 and the lifting column 203 also avoid the problem of the lifting cylinder 211 directly supporting the frame body 300, thus improving the service life of the lifting cylinder 211. The positioning plate 207 on one side of the mounting box 205 is mainly used to position one end of the bottom battery box 301 of the frame body 300, thereby positioning the lifting position of the frame body 300. The roller 210 inside the mounting box 205 mainly... To facilitate easy movement of the frame body 300 on it, the reinforcing plug 212 on the top of the lifting column 203 is mainly used to match the hollow hole 304 installed in the head tube 303 for lifting the frame body 300. The height positioning plates 213 fixedly installed on both sides of the upper part of the lifting platform 204 are mainly used to position the lifting height of the lifting platform 204, and then cooperate with the positioning plate 207 to position the bottom battery box 301, accurately positioning the position between the reinforcing plug 212 and the hollow hole 304 so that the reinforcing plug 212 can be inserted into the hollow hole 304 after moving.

[0029] Working principle and usage process of this utility model:

[0030] When fixing the frame body 300, first move the bottom battery box 301 at the bottom of the frame body 300 to the upper end of the mounting box 205, and gently move the frame body 300 along the roller 210 inside the mounting box 205 so that one side of the bottom battery box 301 at the bottom of the frame body 300 engages with the positioning plate 207. After one end of the bottom battery box 301 is engaged with the positioning plate 207, then activate the double-headed cylinder 209 inside the mounting box 205 to drive the clamping brackets 208 at both ends to close and press against both ends of the bottom battery box 301, thereby fixing the frame body 300 after positioning on the mounting box 205. After the frame body 300 is fixed, the lifting platform 204 is raised so that the height positioning plates 213 on both sides of the lifting platform 204 are raised to the bottom of the support platform 201. At this time, the lifting cylinder 211 at the bottom of the fixing cylinder 202 can be activated to drive the lifting column 203 inside the fixing cylinder 202 to move so that the reinforcing plug 212 at the top of the lifting column 203 can be inserted into the hollow hole 304 inside the head tube 303. After the lifting platform 204 is lowered, the frame body 300 can be fixed by the lifting column 203, so that it can be painted evenly around its perimeter and top and bottom.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
