Technical Field
[0001] The utility model relates to the technical field of electric vehicle parts processing, in particular to a quick clamping tooling for electric vehicle handle pipe fittings. Background Art
[0002] An electric vehicle is a vehicle driven by electricity. The electric vehicle uses a battery as an energy source and converts electrical energy into mechanical energy through components such as a controller and a motor to move, and controls the vehicle speed by changing the magnitude of the current. It conforms to the national trend of energy conservation and environmental protection and greatly facilitates short-distance transportation. Therefore, electric vehicles are very common. The steering handle of an electric vehicle is an important component of the electric vehicle. The cross-section of the steering handle pipe fitting is circular, resulting in poor positioning effect during processing. Therefore, it is necessary to increase the manpower to meet the operation requirements. Therefore, a clamping tooling is designed. The upper die is driven by a cylinder to move up and down, and the upper die and the lower die cooperate to clamp and fix the pipe fitting. However, due to the toughness of the cylinder force, the clamping force is insufficient, resulting in the pipe fitting shaking during drilling and tapping, resulting in unqualified product processing and affecting the cost input of the enterprise.
[0003] In view of the above problems, the present utility model document proposes a quick clamping tooling for electric vehicle handle pipe fittings. Content of the Utility Model
[0004] The utility model provides a quick clamping tooling for electric vehicle handle pipe fittings, which improves the clamping stability of the pipe fittings, reduces the manpower input, and reduces the cost input of the enterprise.
[0005] The utility model provides the following technical solutions:
[0006] A quick clamping tooling for electric vehicle handle pipe fittings includes a main body frame. Between the two opposite side walls of the main body frame, there are parallel sliding blocks and fixed blocks. On the adjacent side surfaces of the sliding block and the fixed block, there is a pressing die. On the other opposite side surface, there is a first hinge member. On the fixed block, there is a positioning die that cooperates with the pressing film. At a position on the inner wall of the main body frame opposite to the first hinge member, there is a second hinge member. A first pull rod is hinged on the first hinge member, and a second pull rod is hinged on the second hinge member. On the outer side wall of the main body frame, there is a bracket. On the bracket, there is a cylinder. The output shaft of the cylinder is provided with a third pull rod. One ends of the first pull rod, the second pull rod, and the third pull rod are hinged together; the sum of the lengths of the first pull rod, the second pull rod, and the thicknesses of the first hinge member and the second hinge member is the same as the distance between the sliding block and the main body frame; on the adjacent surfaces of the pressing die and the positioning die, arc-shaped clamping grooves are opened, and the arc-shaped clamping grooves on the pressing die and the arc-shaped clamping grooves on the positioning die cooperate with each other.
[0007] Further, on the two opposite side walls of the main body frame, there are slide rails, and on the two opposite side surfaces of the sliding block, chutes matching the slide rails are opened.
[0008] Further, relief grooves are formed on both side walls of the main body frame where the slide rails are provided. Matching chutes are formed on the opposite side faces of the fixed block for the slide rails. A screw rod is fixedly arranged on the bottom surface of the chute. After passing through the relief groove, the screw rod is locked and fixed by a lock nut.
[0009] Further, both the first hinge member and the second hinge member include a mounting seat, and two parallel connecting ear plates are fixedly arranged on the mounting seat.
[0010] Further, a connecting groove is formed at one end of the third pull rod, and limiting plates are arranged on the opposite side faces at the other end. The limiting plates are of an "L" - shaped structure. One side wall is locked and fixed on the side wall of the third pull rod by a bolt, and the other side wall is located at the end face of the third pull rod and there is a gap between it and the end face of the third pull rod. A limiting block is arranged on the output shaft of the air cylinder. The limiting block is clamped in the gap and is pressed against the end face of the second pull rod by the limiting plate.
[0011] Further, countersunk holes are formed on the adjacent faces of the pressing die and the positioning die, and countersunk bolts are arranged in the countersunk holes.
[0012] Further, the arc - shaped card slot is a semi - circular card slot. The arc - shaped card slot on the pressing die and the arc - shaped card slot on the positioning die cooperate to form a circular card hole matching the pipe fitting to be processed.
[0013] Further, guide rods are arranged on the adjacent faces of the pressing die and the positioning die, and guide holes matching the guide rods are arranged at the corresponding positions of the positioning die.
[0014] In the present utility model, the air cylinder drives the third pull rod to move. The third pull rod pulls the first pull rod and the second pull rod. Since the second hinge member connected to the second pull rod is fixed, the first hinge member connected to the first pull rod moves. Then, the sliding block moves within the main body frame, and further drives the pressing die to move. The pressing die moves towards the positioning die, clamps the pipe fitting between the pressing die and the positioning die, and thus clamps and fixes the pipe fitting. When the pressing die moves away from the positioning die, the pipe fitting can be loosened and then removed. By controlling the first pull rod and the second pull rod with the air cylinder to press the sliding block, the pressing die is pressed against the positioning die, improving the stability of the pipe fitting clamping.

[0025] Embodiment:
[0026] Referring to Figure 1 、 Figure 2 and Figure 3 As shown, a quick clamping tooling for an electric vehicle handle pipe fitting includes a main frame 1. Between the two symmetric side walls of the main frame 1, there are parallel sliding blocks 2 and fixed blocks 3. On the adjacent side surfaces of the sliding block 2 and the fixed block 3, there is a pressing die 4. On the other symmetric side surface, there is a first hinge member 6. On the fixed block 3, there is a positioning die 5 that cooperates with the pressing die. At a position on the inner wall of the main frame 1 opposite to the first hinge member 6, there is a second hinge member 7. A first pull rod 9 is hinged on the first hinge member 6, and a second pull rod 8 is hinged on the second hinge member 7. On the outer side wall of the main frame 1, there is a bracket, and on the bracket, there is a cylinder 11. The output shaft of the cylinder 11 is provided with a third pull rod 10. One ends of the first pull rod 9, the second pull rod 8, and the third pull rod 10 are hinged together; the sum of the length of the first pull rod 9, the length of the second pull rod 8, and the thicknesses of the first hinge member 6 and the second hinge member 7 is the same as the distance between the sliding block 2 and the main frame 1; arc-shaped clamping grooves 18 are formed on the adjacent surfaces of the pressing die 4 and the positioning die 5, and the arc-shaped clamping groove 18 on the pressing die 4 and the arc-shaped clamping groove 18 on the positioning die 5 cooperate with each other.
[0027] The pipe fitting can be clamped between the pressing die 4 and the positioning die 5 through the cooperation of the arc-shaped clamping groove 18 on the pressing die 4 and the arc-shaped clamping groove 18 on the positioning die 5.
[0028] When the output shaft of the cylinder 11 extends out, the third pull rod 10 pushes the first pull rod 9 and the second pull rod 8, making the first pull rod 9 and the second pull rod 8 horizontal. At the same time, the second pull rod 8 squeezes the sliding block 2, causing the sliding block 2 to move towards the fixed block 3, and further causing the pressing die 4 to press on the positioning die 5. Placing the pipe fitting between the pressing die 4 and the positioning die 5 can clamp and fix the pipe fitting. By controlling the positions of the first pull rod 9 and the second pull rod 8 on the side through the cylinder 11, the cooperation between the pressing die 4 and the positioning die 5 is controlled, and it is not necessary for the cylinder 11 to directly drive the pressing die 4 to move, thereby improving the stability of the pipe fitting clamping.
[0029] On the two symmetric side walls of the main body frame 1, there are slide rails 101, and on the two symmetric side surfaces of the sliding block 2, there are sliding grooves that match the slide rails 101.
[0030] The sliding grooves on the side surface of the sliding block 2 are clamped on the slide rails 101, so that the sliding block 2 can move along the slide rails 101, ensuring that the sliding block 2 can drive the pressing die 4 to cooperate with the positioning die 5 on the fixed block 3.
[0031] On the two side walls of the main body frame 1 where the slide rails 101 are provided, there are also relief grooves 102. On the two symmetric side surfaces of the fixed block 3, there are sliding grooves that match the slide rails 101. A screw rod 14 is fixedly arranged on the bottom surface of the sliding groove. After the screw rod 14 passes through the relief groove 102, it is locked and fixed by a locking nut 15.
[0032] The sliding grooves on the side surface of the fixed block 3 are clamped on the slide rails 101. The screw rod 14 on the fixed block 3 passes through the relief groove 102 and is locked by the locking nut 15. When the locking nut 15 is loosened, the fixed block 3 can slide on the slide rails 101, and the position of the fixed block 3 can be adjusted. Furthermore, the distance between the sliding block 2 and the fixed block 3 can be adjusted to adapt to pipe fittings with different diameters.
[0033] Both the first hinge member 6 and the second hinge member 7 include mounting seats, and on the mounting seats, there are two parallel connecting ear plates fixedly arranged.
[0034] The mounting seats facilitate the installation of the first hinge member 6 and the second hinge member 7, and the connecting ear plates on the mounting seats facilitate the hinging.
[0035] One end of the third pull rod 10 is provided with a connecting groove, and on the two symmetric side surfaces of the other end, there are limit plates 12. The limit plates 12 are of an "L" - shaped structure. One side wall is locked and fixed to the side wall of the third pull rod 10 by a bolt, while the other side wall is located at the end face of the third pull rod 10 and there is a gap between it and the end face of the third pull rod 10. The output shaft of the air cylinder 11 is provided with a limit block 13, and the limit block 13 is clamped in the gap and is pressed against the end face of the second pull rod 8 by the limit plate 12.
[0036] The third pull rod 10 is convenient for hinging with the first pull rod 9 and the second pull rod 8 through the connecting groove, and the other end presses and fixes the limit block 13 of the output shaft of the air cylinder 11 through two limit plates 12, so that the air cylinder 11 is connected to the third pull rod 10.
[0037] On the adjacent surfaces of the pressing die 4 and the positioning die 5, there are countersunk holes 16, and countersunk bolts are arranged in the countersunk holes 16.
[0038] The pressing die 4 is fixed on the sliding block 2 and the positioning die 5 is fixed on the fixed block 3 through the countersunk bolts. At the same time, using the countersunk bolts does not affect the cooperation between the pressing die 4 and the positioning die 5.
[0039] The arc-shaped card slot 18 is a semi-circular card slot. The arc-shaped card slots 18 on the pressing die 4 and the arc-shaped card slots 18 on the positioning die 5 cooperate to form a circular card hole that matches the pipe fitting to be processed.
[0040] Since the cross-section of the pipe fitting is circular, the circular card hole formed by two semi-circular card slots matches the pipe fitting, further improving the clamping stability of the pipe fitting.
[0041] Guide rods are provided on the adjacent surfaces of the pressing die 4 and the positioning film, and guide holes 17 that cooperate with the guide rods are provided at the corresponding positions of the positioning film.
[0042] Through the cooperation of the guide rods and the guide holes 17, the pressing die 4 can accurately cooperate with the positioning die 5, so that the arc-shaped card slots 18 on the pressing die 4 and the positioning die 5 can accurately cooperate, and then the pipe fitting is clamped and fixed.
[0043] During use, the base of the first hinge 6 is fixed to the sliding block 2 by bolts, the base of the second hinge 7 is fixed to the inner side wall of the main body frame 1 by bolts, and the two limit plates 12 are fixed to the end of the third pull rod 10 by bolts. At the same time, the limit block 13 on the output shaft of the cylinder 11 is pressed against the end of the third pull rod 10 through the two limit plates 12. The positioning die 5 is fixed to the fixed block 3 by countersunk head bolts, and the pressing die 4 is fixed to the sliding block 2 by countersunk head bolts. Through the sliding grooves on the fixed block 3 and the sliding block 2, the fixed block 3 and the sliding block 2 are clamped on the slide rail 101 of the main body frame 1. Then, through the locking nut 15 and the screw rod 14 on the fixed block 3, the fixed block 3 is locked and fixed to the main body frame 1. One end of the first pull rod 9 is hinged to the first hinge 6, one end of the second pull rod 8 is hinged to the second hinge 7, and the other end of the first pull rod 9, the other end of the second pull rod 8 and one end of the third pull rod 10 are hinged together, and the assembly of the tooling can be completed. When the output shaft of the cylinder 11 contracts, the third pull rod 10 is pulled. The movement of the third pull rod 10 drives the first pull rod 9 and the second pull rod 8 to rotate. Since the position of the second hinge 7 hinged to the second pull rod 8 is fixed, and the first hinge 6 hinged to the first pull rod 9 is movably arranged, when the third pull rod 10 is pulled, the first hinge 6 will move towards the second hinge 7, driving the sliding block 2 to move towards the second hinge 7, and then the pressing die 4 moves away from the positioning die 5. Then, the pipe fitting is placed at the position of the semi-circular card slot of the positioning die 5, and then the cylinder 11 is started, so that the output shaft of the cylinder 11 extends, pushing the third pull rod 10. The third pull rod 10 pushes the first pull rod 9 and the second pull rod 8 to rotate, so that the first pull rod 9 and the second pull rod 8 are perpendicular to the third pull rod 10. The rotation of the first pull rod 9 will push the sliding block 2 to move towards the fixed block 3, and then the pressing die 4 moves towards the positioning die 5. The semi-circular card slot on the pressing die 4 and the semi-circular card slot on the positioning die 5 cooperate to clamp and fix the pipe fitting.
[0044] In actual use, the bracket is of a "U" - shaped structure, with its two ends fixed to the side of the main frame 1 and the middle part fixed to the cylinder 11.
[0045] The tooling of the present utility model can quickly clamp pipe fittings, improve the stability of the pipe fitting clamping during pipe fitting drilling and tapping, ensure the product quality, save labor input, reduce production costs, and meet the production requirements of enterprises.
[0046] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model; without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
