Description

Technical Field

[0001] This utility model relates to a device for detecting the shape of a multi-angle joystick, belonging to the field of tooling and inspection technology. Background Technology

[0002] Currently in the forklift industry, control levers typically consist of two horizontal links and one diagonal link. One horizontal link has a relatively fixed length, while the horizontal link at the control connection end varies in height and length due to the angle of the diagonal link. Because of its unique shape and variable angles, its appearance is difficult to inspect using conventional methods. Quality issues with the control lever's appearance are usually only discovered after the entire machine is assembled. To ensure the machining quality of control levers, tooling and inspection fixtures have been widely promoted and applied. These fixtures enable rapid inspection of the control lever's appearance before assembly, reducing the inspection burden on quality control personnel, lowering rework rates, and significantly improving production efficiency.

[0003] However, most existing tooling and fixtures can only measure the shape of joysticks at a single angle, and cannot measure joysticks at multiple angles. If multiple angles need to be measured, the tooling and fixtures must be changed multiple times, which is also time-consuming and labor-intensive. Therefore, there is an urgent need in this field for a joystick shape inspection device for multiple angles, so as to solve the problems of difficult joystick measurement, long measurement time, and inability to quickly measure and identify the shape of joysticks at multiple angles. Utility Model Content

[0004] The purpose of this invention is to provide a device for detecting the shape of a joystick at multiple angles, in order to solve the problems of difficult joystick measurement, long measurement time, and inability to quickly measure and identify the shape of joysticks at multiple angles.

[0005] To achieve the above-mentioned technical objectives and effects, this application provides the following technical solution:

[0006] A device for detecting the shape of a multi-angle joystick includes a base plate. A positioning shaft is detachably mounted on one upper surface of the base plate to position the joystick shaft hole horizontally. A transverse positioning seat, a height positioning seat, and a length constraint seat are detachably mounted sequentially on the upper surface of the base plate in a direction away from the positioning shaft. The transverse positioning seat has a detection hole for embedding and fixing the transverse part of the joystick. The height positioning seat has multiple through holes spaced apart in the vertical direction. The through holes are used to pass through the transverse rod of the joystick's operating connection end to constrain the joystick in the vertical direction. The angle between the center positions of the through holes and the detection holes constrains the shape angle of the joystick. The length constraint seat has a stepped groove on the side facing the height positioning seat that corresponds to the multiple through holes.

[0007] Preferably, a plurality of positioning pads are stacked on the upper side of the height positioning seat along the vertical direction. The positioning pads are detachably mounted on the upper surface of the height positioning seat, and two adjacent positioning pads are detachably mounted. The through holes are provided on the upper surfaces of both the height positioning seat and the positioning pads.

[0008] Furthermore, the bottom of the positioning pad is provided with at least one key block, and the upper surface of both the height positioning seat and the positioning pad is provided with a keyway that engages with the key block.

[0009] Furthermore, the key block and the keyway are engaged with a clearance fit.

[0010] Preferably, the lateral positioning seat, the height positioning seat, and the length constraint seat are all fixed to the base plate by means of cylindrical pins, washers, and screws.

[0011] Preferably, the positioning shaft is inserted into the base plate and has a mounting hole for inserting the operating lever on the side facing the transverse positioning seat. A positioning lever is provided on the outer wall of the positioning shaft, and a positioning hole is provided on the positioning lever. An indicator hole that cooperates with the positioning hole is provided on the base plate to rotate the mounting hole to a suitable position.

[0012] Furthermore, the positioning shaft and the base plate are connected by an interference fit.

[0013] The present invention provides a device for detecting the shape of a multi-angle joystick, which has the following advantages:

[0014] This invention uses a horizontal positioning seat, a height positioning seat, and a length constraint seat to constrain and fix each part of the joystick. The height is constrained by a positioning pad, and the length of the joystick is constrained by a length fixing seat, thus adapting to the shape inspection of joysticks at various angles. The structure is stable, and the operation is simple and fast. It can be widely used in the appearance quality inspection of joysticks, reducing the inspection burden of quality inspectors, reducing rework rate, and improving production efficiency.

Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figure 1-4 A device for inspecting the shape of a multi-angle joystick includes a base plate 1. A positioning shaft 2 is detachably mounted on one upper surface of the base plate 1 to position the joystick shaft hole horizontally. A transverse positioning seat 3, a height positioning seat 4, and a length constraint seat 5 are detachably mounted sequentially on the upper surface of the base plate 1 in a direction away from the positioning shaft 2. The transverse positioning seat 3 has a detection hole 31 for embedding the transverse part of the joystick. While fixing the joystick, the device also inspects the shape by measuring the fit between the transverse part of the joystick and the detection hole 31. Price; The height positioning seat 4 has multiple through holes 41 spaced apart in the vertical direction. The through holes 41 are used to pass through the horizontal rod of the control lever connection end to constrain the vertical direction of the control lever. The angle between the center position of the through hole 41 and the detection hole 31 constrains the shape angle of the control lever. At the same time, the shape and shape angle of the control lever can also be detected and evaluated. The length constraint seat 5 has a stepped groove 51 on the side facing the height positioning seat 4, which corresponds to the multiple through holes 41. Different control lever lengths are constrained by different step heights.

[0023] Reference Figures 1-4 Multiple positioning pads 6 are stacked vertically on the upper side of the height positioning seat 4. The positioning pads 6 are detachably installed on the upper surface of the height positioning seat 4. Two adjacent positioning pads 6 are detachably set. Through holes 41 are opened on the upper surfaces of the height positioning seat 4 and the positioning pads 6. By cooperating with different numbers of positioning pads 6, the control levers with different spacings are constrained in the vertical direction.

[0024] Further, at least one key block 61 is integrally formed at the bottom of the positioning cushion block 6, and key grooves 7 for clamping the key block 61 are formed on the upper surfaces of the height positioning seat 4 and the positioning cushion block 6. The key block 61 and the key groove 7 are clamped by clearance fit to restrict the position and angle of the positioning cushion block 6 and prevent rotation. In this embodiment, preferably two key blocks 61 are symmetrically arranged.

[0025] Refer to Figures 1-4 , the positioning shaft 2 is inserted into the bottom plate 1, and an installation hole 21 for inserting the operating lever is formed on the side facing the lateral positioning seat 3. A positioning lever 22 is integrally formed on the outer wall of the positioning shaft 2, and a positioning hole 221 is formed on the positioning lever 22. An indicating hole 11 matching the positioning hole 221 is formed on the bottom plate 1 to quickly transfer the installation hole 21 to an appropriate position. In this embodiment, the positioning shaft 2 and the bottom plate 1 are preferably inserted by interference fit, and can be taken out and rotated by sufficient external force but will not easily move during the detection process.

[0026] Refer to Figures 1-4 , the lateral positioning seat 3, the height positioning seat 4 and the length constraint seat 5 are all positioned and installed by cylindrical pins 8, and then are positioned and fixed on the bottom plate 1 by cooperation of washers 9 and screws 10.

[0027] The working principle of a multi-angle operating lever profile detection device provided by the present utility model is as follows:

[0028] First, the shaft hole of the operating lever needs to be positioned through the positioning shaft 2. The lateral part of the operating lever is restricted, detected and evaluated through the lateral positioning seat 3. The vertical direction of the control connection end of the operating lever is restricted, detected and evaluated through the height positioning seat 4. The length is restricted by the length constraint seat 5. The angle of the operating lever is naturally restricted by the positions of the height positioning seat 4 and the lateral positioning seat 3. The positioning hole 221 on the positioning shaft 2 is aligned with the indicating hole 11 on the bottom plate 1. If there are operating levers at other angles, they can be restricted and fixed by stacking the positioning cushion block 6 and the height positioning block in cooperation. When each part of the operating lever is correctly placed in the inspection tool and can fit each part of the inspection tool, the operating lever is detected and evaluated as qualified at this time. Only one operating lever weld can be detected at a time. The figure shows the superposition of multiple operating lever welds at different angles in three dimensions.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit this utility model in any form or substance. It should be noted that those skilled in the art can make various improvements and additions without departing from this utility model, and these improvements and additions should also be considered within the protection scope of this utility model. Any modifications, alterations, and equivalent changes made by those skilled in the art without departing from the spirit and scope of this utility model using the disclosed technical content are equivalent embodiments of this utility model. Furthermore, any modifications, alterations, and evolutions made to the above embodiments based on the essential technology of this utility model are still within the scope of the technical solution of this utility model.
