Description

Technical Field

[0001] The utility model relates to the technical field of automobile maintenance brackets, in particular to a maintenance bracket for new energy vehicles. Background Art

[0002] New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, and hydrogen engine vehicles. The Chinese patent authorization announcement number is CN221539692U, which states, "Discloses a maintenance bracket for new energy vehicles, including a workbench and a bracket. A motor A is fixed internally to the bracket to drive a rotating shaft A to rotate. A bidirectional screw is fixed to one side of the rotating shaft A to drive a fixing sleeve A and a fixing sleeve B to move toward each other." The above patent points out that existing maintenance brackets for new energy vehicles cannot protect the connection between the circuit and the RF connector, and it is inconvenient to fix the cable. The cable is easily disconnected from the RF connector when it shakes, affecting its use.

[0003] The aforementioned reference document addresses the problem that existing repair brackets for new energy vehicles are inconvenient for fixing parts that need repair on new energy vehicles, and that parts of new energy vehicles are prone to shaking, making it impossible to adjust the position of parts that need repair, resulting in low repair efficiency and affecting use.

[0004] However, when the above-mentioned new energy vehicle maintenance bracket is used to repair new energy vehicle parts, the clamping mechanisms on both sides are not stable enough to clamp the parts. At the same time, when there are special-shaped parts in the new energy vehicle parts, the clamping mechanism cannot be adjusted separately to stably clamp the outer side of the special-shaped parts, and the clamping mechanism cannot be adjusted to expand and position the soft annular parts. The overall practicality of the maintenance bracket is low. For this reason, we propose a maintenance bracket for new energy vehicles. Utility Model Content

[0005] The purpose of the utility model is to provide a maintenance bracket for new energy vehicles. The maintenance bracket of the new energy vehicle can stably clamp the outside of the circular special-shaped parts, and can adjust the clamping mechanism to expand and position the soft annular parts, which makes it more convenient for workers to repair the new energy vehicle parts. The overall practicality of the maintenance bracket is strong.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a maintenance bracket for new energy vehicles, comprising a workbench, a vertical frame, a fixed plate, a ball screw slide and a symmetrically arranged first clamping block and a second clamping block, wherein positioning guide grooves are provided at equal intervals on the front circumference of the fixed plate, a connecting seat is rotatably mounted on the back of the first clamping block, a positioning bolt is threadedly mounted on the circumference of one side of the connecting seat, a chuck is fixedly mounted on the front of the two groups of the first clamping blocks, a threaded rod and a ball screw are threadedly mounted on the outer circumferential surface of the fixed plate, and a guide block is fixedly mounted on the back of the two groups of the connecting seats and the back of the two groups of the second clamping blocks.

[0007] Preferably, the fixing plate is fixedly mounted on the front side of the matching slider in the ball screw slide.

[0008] Preferably, the four groups of positioning guide grooves are in a cross-shaped structure, the interior of the positioning guide grooves and the guide blocks are both in a T-shaped structure, and the four groups of guide blocks slide in the corresponding inner walls of the positioning guide grooves respectively.

[0009] Preferably, the two groups of guide blocks on the back of the second clamping blocks are respectively rotatably connected to one end of the corresponding threaded rod, and the two groups of guide blocks on the back of the connecting seat are respectively threadedly connected to the ball screw, and the outer end of the ball screw is fixedly connected to a handwheel.

[0010] Preferably, the two groups of connecting seats are fixedly connected to the two groups of guide blocks on the back side in a one-to-one correspondence, and positioning holes are provided at equal intervals on the circumference of the connecting seats.

[0011] Preferably, the back side of the first clamping block is a convex structure, and the positioning bolt is used to position the first clamping block.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model drives the guide blocks on both sides to slide in the positioning guide grooves through the ball screw, so that the two groups of first clamping blocks can be brought close to each other to adjust the spacing, so that the inner flat cross-section of the clamping blocks can clamp the new energy vehicle parts, and the two groups of threaded rods can be used separately, so that the two groups of second clamping blocks can be brought close to each other to adjust the spacing. The two groups of second clamping blocks that cooperate separately can improve the clamping stability of the outer side of the parts and can also stably clamp the parts with different shapes.

[0014] The utility model adjusts the positioning bolts on the outsides of the two groups of first clamping blocks so that the clamping heads on the front sides of the two groups of first clamping blocks can be adjusted to a horizontal state, and the first clamping blocks and the connecting seat are positioned with the positioning bolts. In this way, the two groups of horizontal clamping heads can expand and clamp the soft annular components, thereby realizing the expansion and positioning of the soft annular components, making it more convenient for staff to repair new energy vehicle components, and the overall practicality of the maintenance bracket is strong.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-4 The utility model provides a technical solution: a maintenance bracket for new energy vehicles, comprising a workbench 1, a vertical frame 2, a fixed plate 3, a ball screw slide 4, and a symmetrically arranged first clamping block 5 and a second clamping block 6. Positioning guide grooves 31 are evenly spaced on the front circumference of the fixed plate 3. A connecting seat 51 is rotatably mounted on the back of the first clamping block 5. A positioning bolt 53 is threadedly mounted on one side of the circumference of the connecting seat 51.

[0022] The front surfaces of the two sets of first clamping blocks 5 are respectively fixed with clamping heads 7, the outer circumferential surface of the fixing plate 3 is respectively fixed with threaded rods 61 and ball screws 8, and the back surfaces of the two sets of connecting seats 51 and the back surfaces of the two sets of second clamping blocks 6 are respectively fixed with guide blocks 82;

[0023] The ball screw 8 drives the guide blocks 82 on both sides to slide in the positioning guide groove 31, so that the two groups of first clamping blocks 5 can be brought close to each other to adjust the spacing, so that the inner flat cross-section of the clamping blocks can clamp the new energy vehicle parts, and the two groups of threaded rods 61 can be used separately, so that the two groups of second clamping blocks 6 can be brought close to each other to adjust the spacing. The two groups of second clamping blocks 6 that cooperate with each other can improve the stability of clamping the outer side of the parts, and can also play a role in stably clamping the parts with different shapes;

[0024] By adjusting the positioning bolts 53 on the outside of the two groups of first clamping blocks 5, the clamping heads 7 on the front of the two groups of first clamping blocks 5 can be adjusted to a horizontal state, and the first clamping blocks 5 and the connecting seat 51 are positioned with the positioning bolts 53, so that the two groups of horizontal clamping heads 7 can expand and clamp the soft annular components, thereby realizing the expansion and positioning of the soft annular components, making it more convenient for staff to repair new energy vehicle components, and the overall practicality of the maintenance bracket is relatively strong.

[0025] Among them, the fixed plate 3 is fixedly installed on the front side of the matching slider in the ball screw slide 4, and the ball screw slide 4 can adjust the distance between the fixed plate 3 and the workbench 1.

[0026] Among them, the four groups of positioning guide grooves 31 are cross-shaped structures, and the interior of the positioning guide grooves 31 and the guide blocks 82 are T-shaped structures. The four groups of guide blocks 82 slide in the corresponding inner walls of the positioning guide grooves 31 respectively, and the guide blocks 82 on the back of the two groups of second clamping blocks 6 are respectively rotatably connected to one end of the corresponding threaded rods 61, and the guide blocks 82 on the back of the two groups of connecting seats 51 are respectively threadedly connected to the ball screw 8. The outer end of the ball screw 8 is fixedly connected with a handwheel 81, and the ball screw 8 is driven by the ball screw 8 to drive the guide blocks 82 on both sides to slide in the positioning guide grooves 31, so that the two groups of first clamping blocks 5 can be brought close to each other to adjust the spacing, so that the inner flat section of the clamping block can clamp the new energy vehicle components, and the two groups of threaded rods 61 can be used separately, so that the two groups of second clamping blocks 6 can be brought close to each other to adjust the spacing. The two groups of separately matched second clamping blocks 6 can improve the stability of clamping the outside of the components, and at the same time can stably clamp the heterogeneous components.

[0027] Among them, the two groups of connecting seats 51 are respectively fixedly connected to the two groups of guide blocks 82 on the back side in a one-to-one correspondence. Positioning holes 52 are opened at equal intervals on the circumference of the connecting seat 51. The back of the first clamping block 5 is a convex structure. The positioning bolts 53 are used to position the first clamping block 5. By adjusting the positioning bolts 53 on the outside of the two groups of first clamping blocks 5, the clamping heads 7 on the front sides of the two groups of first clamping blocks 5 can be adjusted to a horizontal state, and the positioning bolts 53 are used to position the first clamping block 5 and the connecting seat 51. In this way, the two groups of horizontal clamping heads 7 can expand and clamp the soft annular components.

[0028] Working principle: When in use, when clamping and repairing annular and special-shaped parts of new energy vehicles, the ball screw 8 can be used to drive the guide blocks 82 on both sides to slide in the positioning guide groove 31, so that the two groups of first clamping blocks 5 can be brought close to each other to adjust the spacing, so that the inner flat cross-section of the clamping blocks can clamp the new energy vehicle parts, and the two groups of threaded rods 61 can be used separately, so that the two groups of second clamping blocks 6 can be brought close to each other to adjust the spacing. The two groups of second clamping blocks 6 that cooperate separately can improve the stability of clamping the outer side of the parts, and at the same time can stably clamp the special-shaped parts;

[0029] When repairing soft annular parts such as transmission belts in new energy vehicles, the positioning bolts 53 on the outside of the two groups of first clamping blocks 5 are adjusted so that the clamping heads 7 on the front of the two groups of first clamping blocks 5 can be adjusted to a horizontal state, and the first clamping blocks 5 and the connecting seat 51 are positioned with the positioning bolts 53. In this way, the two groups of horizontal clamping heads 7 can expand and clamp the soft annular parts, thereby realizing the expansion and positioning of the soft annular parts, making it more convenient for staff to repair new energy vehicle parts, and the overall practicality of the maintenance bracket is relatively strong.
