[0031] As described above, the component assembly and positioning fixture for rail vehicles achieves rapid and precise adjustment and temporary fixation of the components to be assembled in three-dimensional space through the sliding function of its components in the longitudinal, lateral, and height directions. This overcomes the inherent defects of traditional manual measurement and positioning with tape measures.

The component clamping assembly is slidably connected to the support column 300 along the height direction.

[0035] In one embodiment of the present invention, the component clamping assembly includes: a sliding sleeve 610, which is slidably connected to the support column 300 along the height direction; a connecting arm 620, one end of which is connected to the sliding sleeve 610; and a clamping member 630, which is connected to the other end of the connecting arm 620.

[0036] Furthermore, in one embodiment of the present invention, the clamping member 630 includes: a C-shaped clamping seat, which is connected to one end of the connecting arm 620; and a clamping locking member 640, which is disposed on the C-shaped clamping seat and is used to lock the part to be assembled in the C-shaped clamping seat.

[0037] Specifically, such as Figures 1 to 3 As shown, the base body 100 includes a first substrate 110, a second substrate 120, a third substrate 130, and a fourth substrate 140. The first substrate 110, second substrate 120, third substrate 130, and fourth substrate 140 are arranged parallel to each other longitudinally and spaced apart sequentially. The first substrate 110, second substrate 120, third substrate 130, and fourth substrate 140 all extend laterally.

[0038] The transverse slide block 200 includes a slide table 210 and four guide claws 220, which are slidably connected to four transverse guide grooves. A transverse dimension pointer is set on the slide table 210 at the position corresponding to the two transverse scales 170, so that the transverse dimension of the transverse slide block 200 can be accurately determined from both sides.

[0039] like Figures 1 to 4As shown, a longitudinal guide groove is formed on the slide table 210. The bottom end of the support column 300 is slidably connected to the interior of the longitudinal guide groove. A longitudinal dimension pointer is also provided on the support column 300 to accurately determine the longitudinal dimension of the support column 300.

A height dimension pointer is provided on the sliding sleeve 610 to accurately determine the height dimension of the sliding sleeve 610. The connecting arm 620 is arranged in a direction parallel to the horizontal plane, with one end connected to the sliding sleeve 610 and the other end connected to the clamping member 630. For example, the clamping member 630 can be a C-shaped clamping seat with a clamping area. A clamping locking member 640 is also installed on the C-shaped clamping seat. The part to be assembled can be placed in the clamping area and locked by the clamping locking member 640. For example, the clamping locking element 640 is a locking screw, which passes through and connects to one side of the C-shaped clamping seat. The part to be assembled can be locked onto the locking screw and the seat surface of the C-shaped clamping seat. By adjusting the insertion depth of the locking screw, it can be adapted to parts of different sizes.

[0040] Normally, the parts to be assembled need to be horizontally clamped within the clamping member 630. In one embodiment of this utility model, the part clamping assembly further includes a level detection device 700, which is disposed at one end of the connecting arm 620 near the clamping member 630 and is used to detect the levelness of the parts to be assembled. This improves assembly accuracy. For example, the level detection device 700 includes, but is not limited to, a laser level.

[0041] In one embodiment of this utility model, the positioning sliding base assembly further includes: a lateral locking member 510, which is disposed between the lateral sliding block 200 and the base body 100 and is used to lock the relative position of the lateral sliding block 200 and the base body 100; a longitudinal locking member, which is disposed between the support column 300 and the lateral sliding block 200 and is used to lock the relative position of the support column 300 and the lateral sliding block 200; and a height locking member 520, which is disposed between the component clamping assembly and the support column 300 and is used to lock the relative position of the component clamping assembly and the support column 300.

[0042] For example, the lateral locking member 510, the longitudinal locking member, and the height locking member 520 all include, but are not limited to, locking screws.

[0044] More specifically, in one embodiment of the present invention, the transverse drive mechanism includes: a lead screw 410, which is transversely connected to the base body 100; and a lead screw nut, which is connected to the transverse slide 200 and threadedly connected to the lead screw 410.

[0045] For example, such as Figures 1 to 3 As shown, two fixing plates 160 are spaced apart between the second substrate 120 and the third substrate 130. Both fixing plates 160 are arranged in a direction perpendicular to the second substrate 120 and the third substrate 130. The two ends of the lead screw 410 are smooth connecting sections, and the middle of the lead screw 410 is a threaded connecting section. The smooth connecting sections at both ends of the lead screw 410 are rotatably connected to the two fixing plates 160, respectively. Bearings 430 are installed between the smooth connecting sections and the corresponding fixing plates 160. A lead screw nut is provided at the bottom of the transverse slide 200, and the lead screw nut is connected to the threaded section of the lead screw 410. A rotating handle 420 is provided at one end of the lead screw 410. By operating the rotating handle 420, the lead screw 410 can be driven to rotate, and thus, under the action of the lead screw nut, the transverse slide 200 moves laterally relative to the base body 100.

[0046] In one embodiment of the present invention, the positioning sliding base assembly further includes a positioning connector 800, which is connected to the base body 100 and is used to connect the base body 100 to the inner wall of the driver's cab of the rail vehicle.

[0047] For example, such as Figures 1 to 3 As shown, the positioning connector 800 includes a positioning seat 810 and a positioning body 820. The positioning seat 810 can be connected to the base body 100, and the positioning body 820 is disposed on the positioning seat 810. The positioning seat 810 is flush with the bottom surface of the base body 100 and can fit against any position on the inner wall of the driver's cab to avoid affecting the levelness of the base body 100. The positioning body 820 can be connected between the inner wall of the driver's cab and the positioning seat 810, thereby fixing the base body 100 to the target position on the inner wall of the driver's cab. The positioning body 820 includes, but is not limited to, a magnetic positioning body 820.

[0048] To improve the reliability and accuracy of the positioning connection, a positioning connector 800 can be set at each of the four corners of the base body 100.
