Description

Technical Field

[0001] This utility model belongs to the field of welding fixture technology, and in particular relates to a welding positioning fixture for a control lever. Background Technology

[0002] The clutch lever is one of the main components of a car. By operating the clutch lever, the driver can disengage and engage the engine and transmission, thereby reducing shock during gear shifts and protecting the engine. (See attached image) Figure 1 As shown, the existing joystick includes a joystick body 100 and a switch plate 200. The joystick body 100 includes a horizontally oriented curved section, which is integrally formed by two horizontal sections and one inclined section, and a vertical section integrally and perpendicularly arranged with the horizontal curved section. During processing, the switch plate 200 needs to be welded to the horizontal section of the horizontal curved section near the vertical section, and a flat washer 300 also needs to be welded to the vertical section.

[0003] Traditional welding methods involve first clamping and positioning the control lever 100 using a clamping mechanism, and then welding the switch plate 200 and flat washer 300 onto the control lever 100. This traditional welding method is very inconvenient, as the welding positions of the switch plate 200 and flat washer 300 cannot be quickly and accurately determined, resulting in low welding efficiency. Furthermore, the welding position is prone to deviation, affecting product quality. Therefore, we propose a control lever welding positioning fixture to solve the aforementioned problems. Utility Model Content

[0004] In view of this, in order to solve the problems that traditional welding methods are not only very inconvenient to operate, but also prone to deviation in welding position, resulting in low welding efficiency and affecting product quality, this utility model provides a joystick welding positioning fixture.

The second positioning component is located on the top of the base and between the slot and the strip opening, and is used for the connection and positioning of the switch pressure plate.

[0006] Furthermore, the first positioning component includes a positioning plate disposed on the top of the base, and one side of the positioning plate is provided with a curved surface adapted to the lateral curved section of the control lever.

[0007] Furthermore, the zigzag surface includes a first plane, an inclined plane, and a second plane connected in sequence. The first plane is located on the side away from the slot, and the inclined plane causes the width of the positioning plate to gradually narrow from the first plane to the second plane.

[0008] Furthermore, two positioning rods are symmetrically fixedly connected to the bottom of the positioning plate, and two positioning holes are symmetrically opened on the top of the base to be inserted into the corresponding positioning rods.

[0009] Furthermore, the second positioning component includes a protrusion and a insertion rod. The protrusion is integrally formed on one side edge of the top of the base, and one side of the protrusion has an insertion hole for interlocking with the insertion rod.

[0010] Furthermore, one side of the protrusion extends outward and is integrally provided with a boss, and the boss is located at the bottom of one side of the protrusion.

[0011] The embodiments of this utility model have the following beneficial effects: This invention utilizes the cooperation of a positioning plate and a through hole to quickly position the control lever, simplifying operation. The guide strip opening ensures precise contact and positioning between the switch plate and the control lever, and the insertion rod connects and positions the switch plate, guaranteeing welding accuracy, improving product welding quality, and increasing welding efficiency. It also facilitates integrated welding of flat washers, enhancing the overall practicality of the fixture.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this utility model. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0016] Please see Figures 2-6 As shown, this embodiment provides a joystick welding positioning fixture, including a base 1. A slot 11 is formed on one side of the top of the base 1, and a through hole 15 is formed on the inner bottom wall of the slot 11 for the insertion and positioning of the vertical extension of the joystick body 100. A circular positioning groove 14, concentric with the through hole 15, is formed on the inner bottom wall of the slot 11 for the placement and positioning of the flat washer 300. A strip-shaped opening 12 is formed on the top side of the base 1 near the slot 11 for the embedding and positioning of the switch pressure plate 200.

[0017] This invention can be used in the field of joystick welding positioning fixtures, and can also be applied to other fields.

[0018] The fixture also includes a positioning plate 3 located on the top of the base 1. One side of the positioning plate 3 has a curved surface adapted to the transverse curved section of the control lever. The curved surface includes a first plane 31, an inclined surface 32, and a second plane 33 connected in sequence. The first plane 31 is located on the side away from the slot 11, and the inclined surface 32 makes the width of the positioning plate 3 gradually narrow from the first plane 31 to the second plane 33. When positioning the control lever 100, the transverse curved section is placed horizontally on the top of the base 1 and positioned and engaged by the curved surface of the positioning plate 3. At the same time, the vertical section of the control lever 100 is inserted directly downward into the through hole 15, thereby completing the positioning of the control lever 100. Before positioning the control lever 100, a flat washer 300 needs to be placed in the circular positioning groove 14, and then the control lever 100 is inserted into the through hole 15 for complete positioning. Additionally, a rubber cylindrical sleeve can be installed inside the through hole 15. The vertical section of the control lever 100 is inserted into the rubber cylindrical sleeve, which improves the stability of the insertion and protects the outer wall of the lever from friction, preventing scratches caused by friction with the inner wall of the through hole 15. Two positioning rods 5 are symmetrically fixedly connected to the bottom of the positioning plate 3, and two positioning holes 13 are symmetrically opened on the top of the base 1 to be inserted into the corresponding positioning rods 5. The movable insertion of the positioning rods 5 into the positioning holes 13 facilitates the installation or removal of the positioning plate 3, thereby making it easy to replace different models of positioning plates 3 to adapt to different curved sections of the control lever 100.

[0019] The fixture also includes a protrusion 2 and a rod 4. The protrusion 2 is integrally formed on the top edge of the base 1 and located between the slot 11 and the strip opening 12, used for the connection and positioning of the switch plate 200. The rod 4 is a T-shaped rod. A socket 21 for use with the rod 4 is provided on one side of the protrusion 2. After the operating lever 100 is positioned, the switch plate 200 is slid inward along the inside of the strip opening 12 and abuts against the operating lever 100. At this time, the pin hole on the switch plate 200 corresponds to the socket 21. Then, the rod 4 is inserted into the pin hole through the socket 21, thereby completing the positioning and connection of the switch plate 200 and ensuring the stability of the welding. One side of the protrusion 2 extends outward and is integrally provided with a boss 22, which is located at the bottom of one side of the protrusion 2. The boss 22 can support the part of the switch plate 200 that extends beyond the base 1, thereby further improving the stability of positioning and the welding accuracy.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
