[0037] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] like Figures 1 to 3 As shown, the clamping tool for paint spraying on the passenger door of the present invention includes a first clamping unit 1 for clamping the door column 100 and a second clamping unit 2 for clamping the inner frame of the passenger door 200, wherein the first clamping unit 1 and the second clamping unit 2 are located on the inner side of the door column 100 and the passenger door 200 when the first clamping unit 1 and the second clamping unit 2 are clamped to the door column 100 and the passenger door 200.

[0039] like Figures 1 to 3 As shown, the first clamping unit 1 includes a first clamping seat 11, a first clamping head 12 rotatably connected to the first clamping seat 11, and a first push rod 13 provided on the first clamping seat 11, wherein when the door column 100 is clamped, the door column 100 is located between the first clamping seat 11 and the first clamping head 12, and the first clamping unit 1 clamps the door column 100 from both sides thereof. The first clamping seat 11 and the first clamping head 12 are rotatably connected via a pin shaft.

[0040] like Figure 1 and Figure 3As shown, the second clamping unit 2 includes a second clamping seat 21, a second clamping head 22 rotatably connected to the second clamping seat 21, and a second push rod 23 provided on the second clamping seat 21, wherein when the passenger door 200 is clamped, the inner frame of the passenger door 200 is located between the second clamping seat 21 and the second clamping head 22, and the second clamping unit 2 clamps the inner frame of the passenger door 200 from both sides. The second clamping seat 21 and the second clamping head 22 are rotatably connected via a pin shaft.

[0041] The first clamping head 12 and the second clamping head 22 are arranged adjacent to each other and are rotatably connected together, so that the passenger door 200 can rotate relative to the door column 100 after clamping, that is, the passenger door 200 has a predetermined spraying position and an opening position relative to the door column 100 after clamping. In layman's terms, the passenger door 200 can be opened and closed after clamping. In this embodiment, Figure 3 As shown, the door pillar 100 is located on the left side of the passenger door 200 , the first clamping head 12 acts on the right side of the door pillar 100 , and the second clamping head 22 acts on the left side of the upper frame of the passenger door 200 .

[0042] Specifically, Figures 1 to 3 As shown, the first clamping head 12 includes an X-direction plate 121 for abutting against the inner side surface of the door column 100 and a Y-direction plate 122 for abutting against the right side surface of the door column 100, the X-direction plate 121 is rotatably connected to the first clamping seat 11, and the Y-direction plate 122 is provided with an open clamping groove 123 for avoiding the second clamping head 22, the second clamping head 22 extends into the open clamping groove 123, and is rotatably connected to the notch on the Y-direction plate 122.

[0043] The structural design of the first clamping ram 12 can enhance the clamping effect on the door pillar 100. The setting of the opening clamping groove 123 enables the passenger door 200 to have a sufficient rotation range to make the paint spraying surface of the passenger door 200 flush with the paint spraying surface of the door pillar 100, thereby facilitating the overall paint spraying.

[0044] like Figure 1 and Figure 3 As shown, the second clamping head 22 has an inclined surface 223 on one side adjacent to the first clamping head 12 to increase the rotation angle of the second clamping head 22, reduce interference, and facilitate the second clamping head 22 to rotate into the opening clamping groove 123 to make the paint spraying surface of the passenger door 200 flush with the paint spraying surface of the door pillar 100. Correspondingly, the bottom of the opening clamping groove 123 can also be set as an inclined surface.

[0045] Specifically, Figure 1 and Figure 3 As shown, the second clamping head 22 has a connecting plate 221 extending along the X direction, and the second clamping seat 21 is rotatably connected to the connecting plate 221. When the second clamping unit 2 clamps the inner frame of the passenger door 200, the connecting plate 221 abuts against the inner side surface of the inner frame of the passenger door 200, thereby enhancing the clamping effect on the passenger door 200.

[0046] Furthermore, if Figure 1 and Figure 3 As shown, the second clamping seat 21 is provided with a waist-shaped groove 211 arranged along the Y direction, and the second clamping seat 21 is rotatably connected with the connecting plate 221 through a pin shaft, wherein the pin shaft is arranged in the waist-shaped groove 211 .

[0047] like Figure 3 As shown, when the passenger door 200 is clamped, the pin shaft is located at the end of the waist-shaped groove 211 away from the passenger door 200. In this way, when the second clamping unit 2 is released, the second clamping seat 21 can be pulled along the Y direction so that the second clamping seat 21 and the passenger door 200 can be quickly separated, thereby facilitating the separation of the passenger door 200 and the second clamping unit 2.

[0048] like Figure 3 As shown, when the clamping tool of the present invention clamps the door column 100 and the passenger door 200, the rotation connection point of the first clamping head 12 and the second clamping head 22 is located outside the door column 100 and the passenger door 200, so that when the tool is used, the opening and closing of the passenger door 200 will not interfere with the door column 100, which is convenient to operate and has high practicality. Figure 3 As shown, when the passenger door 200 is in the spraying position (closed state), the door pillar 100 and the passenger door 200 remain flush.

[0049] The present invention can clamp and fix the door pillar 100 and the passenger door 200 respectively and connect the two together, so that the door pillar (bus body) and the passenger door can be sprayed with paint simultaneously and synchronously, which well ensures the consistency of the paint state of the bus body and the passenger door during spraying, can avoid the color difference between the two, and effectively guarantees the overall appearance quality of the bus.

[0050] In the present invention, the first clamping head 12 and the second clamping head 22 are rotatably connected together, so that the passenger door can rotate relative to the door column after clamping, and the passenger door can be opened and closed, that is, the passenger door has a predetermined spraying position and an open position. In this way, when spraying paint, it will not affect other types of work entering the interior of the car body to work, which facilitates people to enter and exit the bus, and allows multiple types of work to be carried out at the same time, thereby improving the overall production efficiency of the bus.

[0051] like Figure 1 and Figure 3 As shown, the first push rod 13 includes a first stud 131 threadedly connected to the first clamping seat 11 and a first handle 132 connected to the first stud 131, and the second push rod 23 includes a second stud 231 threadedly connected to the second clamping seat 21 and a second handle 232 connected to the second stud 231.

[0052] The first stud 131 and the second stud 231 are used to press the first clamping head 12 and the second clamping head 22 respectively. The first stud 131 and the second stud 231 can be driven to move by rotating the first handle 132 and the second handle 232. Such a structure is simple in design, easy to manufacture and low in cost.

[0053] Furthermore, the first stud 131 is arranged along the Y direction, and the second stud 231 is arranged along the X direction, so that the installation distance between the first handle 132 and the second handle 232 can be avoided to be too small, the operating space of the operating handles is increased, and the manual operation of the two handles is convenient.

[0054] In one embodiment, the portion of the first clamping seat 11 in contact with the door pillar 100 is configured as a mesh surface, and the portion of the second clamping seat 21 in contact with the inner frame of the passenger door 200 is also configured as a mesh surface, so as to increase the friction force during clamping and further enhance the clamping effect on the door pillar and the passenger door.

[0055] In one embodiment, if Figure 1 and Figure 3 As shown, a backing plate 24 is welded on the contact surface of the second clamping ram 22 for contacting the second stud 231, and the second stud 231 abuts against the backing plate 24 during clamping. In this embodiment, the provision of the backing plate 24 increases the contact area with the second stud 231, making the second stud 231 more stable during clamping.

[0056] In one embodiment, if Figure 3As shown, the portion of the second clamping head 22 for abutting against the left side of the inner frame of the passenger door 200 has a protrusion 222, and the protrusion 222 is used to be stuck in the process hole on the left side of the inner frame of the passenger door 200 to play an auxiliary positioning and anti-slipping role.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
