Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically to a fixture for processing automotive dashboards. Background Technology

[0002] The car dashboard is part of the car's control system. It is generally composed of a housing, various displays, indicator lights, and electronic control modules. During the manufacturing process of the car dashboard housing, clamps are used to hold and fix the dashboard in place, which facilitates subsequent cutting and other processing.

[0003] A search revealed Chinese patent application CN202320905678.9, which discloses a fixture for machining automotive dashboards. The fixture includes a crossbeam, a fixture adjusting beam, an adjusting assembly, a propulsion cylinder assembly, and a fixture hand. The two ends of the crossbeam are slidably connected to the fixture adjusting beam, which is connected to the crossbeam via the adjusting assembly. The propulsion cylinder assembly is fixedly mounted on the fixture adjusting beam, and its power output end is power-connected to the fixture hand. In this prior art, the fixture adjusting beam is mounted on the crossbeam, and a linear propulsion cylinder is fixedly mounted on it. The linear propulsion cylinder drives a crank connecting rod, and the rotation of the crank connecting rod causes the fixture hand to rotate vertically, thereby causing the dashboard to flip circumferentially. Simultaneously, the crossbeam can drive the fixture adjusting beam to move in opposite directions horizontally, thus enabling the clamping of dashboards of different specifications.

[0004] In the aforementioned prior art, a linear propulsion cylinder mounted on the clamp adjustment beam drives the crank-connecting rod assembly to rotate, thereby using the crank-connecting rod assembly to rotate the clamped instrument panel. Although this clamping method can rotate the instrument panel to a certain extent, the clamping plates on both sides of the clamp are straight plates. Since the instrument panels are all designed to be elliptical with a certain curvature at both ends, when the instrument panel is clamped using straight plates, the contact area between the clamping plates and the instrument panel is small, resulting in poor clamping stability. Utility Model Content

[0005] The purpose of this utility model is to provide a jig for processing automotive dashboards, which solves the problem that existing jigs for processing automotive dashboards are not easy to adjust according to the curvature of the two ends of the dashboard when clamping it, resulting in poor clamping stability.

[0006] This utility model provides the following technical solution: a fixture for processing automotive dashboards, including a base, brackets fixedly connected to both ends of the base, and a fixed frame fixedly connected to the upper end of the brackets.

A double-threaded rod is fixedly connected to the output shaft of the motor, and both ends of the double-threaded rod are rotatably connected to the fixed frame. Threaded plates are threaded on the outer sides of both ends of the double-threaded rod, and a movable plate is fixedly connected to the end of the threaded plate away from the fixed frame.

[0007] Through the above technical solution, the threaded engagement between the double-ended threaded rod and the threaded plate allows the double-ended threaded rod to drive the two sets of threaded plates to move relative to each other.

[0008] As a preferred embodiment of the above technical solution, a first insert rod is inserted into one end of the movable plate, and a spring is fixedly connected to one end of the first insert rod inserted into the movable plate, and the end of the spring away from the first insert rod is fixedly connected to the movable plate.

[0009] With the above technical solution, the first insert rod is inserted into the moving plate to compress the spring, and then the elastic potential energy of the spring can be used to push the first insert rod to pop out and return to its original position.

[0010] As a preferred embodiment of the above technical solution, a locking hole is provided inside one end of the first insertion rod, and multiple sets of locking holes are arranged in a linear array on the first insertion rod.

[0011] Through the above technical solution, by opening multiple sets of locking holes on the first insertion rod, the third insertion rod can be positioned and fixed according to the depth of the first insertion rod inserted into the moving plate.

[0012] As a preferred embodiment of the above technical solution, a second insert is inserted into the inner side of the end of the spring away from the first insert, and the end of the second insert away from the first insert is fixedly connected to the movable plate. A sleeve is sleeved on the outer side of the end of the second insert near the first insert, and the end of the sleeve away from the second insert is fixedly connected to the first insert.

[0013] The above technical solution utilizes a sleeve that moves outside the second insertion rod to restrict the insertion movement of the first insertion rod.

[0014] As a preferred embodiment of the above technical solution, a rubber pad is fixedly connected to the end of the first insertion rod away from the spring, and a slot is provided at the end of the rubber pad away from the first insertion rod.

[0015] The above technical solution uses rubber pads and slots to adhere to and restrict the connection between the rubber pads and the two ends of the instrument panel.

[0016] As a preferred embodiment of the above technical solution, a fixed plate is fixedly connected to the upper side of the movable plate away from the threaded plate, and an electric telescopic rod is fixedly connected to the upper end of the fixed plate. A top plate is fixedly connected to the lower end of the electric telescopic rod, and multiple sets of third insert rods are fixedly connected to the lower end of the top plate. The lower end of the third insert rod passes through the movable plate and is inserted into the card hole.

[0017] The above technical solution utilizes the operation of an electric telescopic rod to move and adjust the top plate and the third insertion rod.

[0018] As a preferred embodiment of the above technical solution, the electric telescopic rod is provided with a first positioning plate on both sides, and the upper end of the first positioning plate is fixedly connected to a fixed plate. A slider is inserted inside the lower end of the first positioning plate, and a second positioning plate is fixedly connected to the end of the slider away from the first positioning plate. The lower end of the second positioning plate is fixedly connected to the top plate.

[0019] The above technical solution restricts the movement of the top plate by using the second positioning plate to drive the slider to move within the first positioning plate.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a fixture for processing automotive dashboards, including a base 1, with brackets 11 fixedly connected to both ends of the base 1, and a fixed frame 12 fixedly connected to the upper end of the brackets 11. A clamping component 2 is provided at one end of the fixed frame 12, and the clamping component 2 includes a motor 21 installed at one end of the fixed frame 12. A double-threaded rod 22 is fixedly connected to the output shaft of the motor 21, and both ends of the double-threaded rod 22 are rotatably connected to the fixed frame 12. Threaded plates 23 are threadedly engaged on the outer sides of both ends of the double-threaded rod 22, and a movable plate 24 is fixedly connected to the end of the threaded plate 23 away from the fixed frame 12. The clamping component 2 can be adjusted to clamp according to different shapes of dashboards, increasing the contact area of ​​clamping and thus improving clamping stability.

[0029] like Figure 3 As shown, a first insert rod 25 is inserted into one end of the movable plate 24, and a spring 26 is fixedly connected to one end of the first insert rod 25 inserted into the movable plate 24. The end of the spring 26 away from the first insert rod 25 is fixedly connected to the movable plate 24. When the first insert rod 25 is squeezed, it is inserted into the movable plate 24 to compress the spring 26.

[0030] like Figure 2 and Figure 3 As shown, a locking hole 27 is provided inside one end of the first insertion rod 25, and multiple sets of locking holes 27 are arranged in a linear array on the first insertion rod 25. The third insertion rod 215 can be inserted through the multiple sets of locking holes 27 to lock and fix the first insertion rod 25.

[0031] like Figure 3 As shown, a second insert rod 28 is inserted into the inner side of the end of the spring 26 away from the first insert rod 25, and the end of the second insert rod 28 away from the first insert rod 25 is fixedly connected to the movable plate 24. A sleeve 29 is sleeved on the outer side of the end of the second insert rod 28 close to the first insert rod 25, and the end of the sleeve 29 away from the second insert rod 28 is fixedly connected to the first insert rod 25. When the first insert rod 25 moves, it drives the sleeve 29 to move on the outer side of the second insert rod 28. The movement of the first insert rod 25 is restricted by the second insert rod 28 and the sleeve 29.

[0032] like Figure 1 and Figure 3 As shown, a rubber pad 210 is fixedly connected to the end of the first insert rod 25 away from the spring 26, and a slot 211 is opened at the end of the rubber pad 210 away from the first insert rod 25. The instrument panel is inserted into the slot 211 in the rubber pad 210, and the instrument panel is locked in place by the rubber pad 210 and the slot 211.

[0033] like Figure 1 and Figure 2 As shown, a fixed plate 212 is fixedly connected to the upper side of the movable plate 24 away from the threaded plate 23, and an electric telescopic rod 213 is fixedly connected to the upper end of the fixed plate 212. A top plate 214 is fixedly connected to the lower end of the electric telescopic rod 213, and multiple sets of third insert rods 215 are fixedly connected to the lower end of the top plate 214. The lower end of the third insert rod 215 passes through the movable plate 24 and is inserted into the locking hole 27. With the support of the fixed plate 212, the electric telescopic rod 213 is activated. After the electric telescopic rod 213 is activated, it pulls the top plate 214 and the third insert rods 215 to move.

[0034] like Figure 4 As shown, the electric telescopic rod 213 is provided with a first positioning plate 216 on both sides, and the upper end of the first positioning plate 216 is fixedly connected to the fixed plate 212. A slider 217 is inserted into the lower end of the first positioning plate 216, and a second positioning plate 218 is fixedly connected to the end of the slider 217 away from the first positioning plate 216. The lower end of the second positioning plate 218 is fixedly connected to the top plate 214. The second positioning plate 218 drives the slider 217 to move within the first positioning plate 216, which can restrict the movement of the top plate 214 and the third insert rod 215.

[0035] Working principle: When using a clamp to hold and fix the car dashboard, first place the dashboard between two sets of rubber pads 210, then start the motor 21. After the motor 21 starts, the output shaft drives the double-threaded rod 22 to rotate. After the double-threaded rod 22 rotates, it engages with the threads of two sets of threaded plates 23, causing the threaded plates 23 to move relative to the moving plate 24. After the moving plate 24 moves, it brings the rubber pads 210 and the slots 211 closer to the dashboard. When the rubber pads 210 and the slots 211 are about to fit against the dashboard, the motor 210 is started under the support of the fixing plate 212. When the electric telescopic rod 213 is activated, its output shaft pulls the top plate 214 and the third insert rod 215 upwards. As the top plate 214 moves, it drives the second positioning plate 218 and the slider 217 to move within the first positioning plate 216. Subsequently, when the third insert rod 215 is pulled out of the locking hole 27, the moving plate 24 continues to drive the rubber pad 210 and the locking groove 211 to move. After the locking groove 211 is fitted onto both ends of the instrument panel, as the moving plate 24 continues to move, the instrument panel pushes the rubber pads 210 on both sides in the opposite direction. The rubber pads 210, after being pushed, compress the first... A first insertion rod 25, after being compressed, is inserted into the moving plate 24 and compressed by the spring 26. During insertion, the first insertion rod 25 is restrained by the second insertion rod 28 and the sleeve 29. Due to the curvature of both ends of the instrument panel, the contact and compression times of the multiple sets of first insertion rods 25 differ, resulting in varying lengths of the first insertion rods 25 inserted into the moving plate 24. When the rubber pads 210 on both sides are fully in contact with and compressed against both ends of the instrument panel, the motor 21 is turned off, and the electric telescopic rod 213 is controlled to extend back to its original position. After the telescopic rod 213 extends, it pushes the top plate 214 and the third insertion rod 215 downward. After the third insertion rod 215 moves downward, it is inserted into the locking hole 27 to lock and fix the multiple sets of first insertion rods 25. Then, the clamped instrument panel is processed. After the processing is completed, it is only necessary to start the motor 21 to make its output shaft rotate in the opposite direction so that the two sets of moving plates 24 drive the rubber pad 210 and the locking groove 211 away from the instrument panel. Then, the same model of instrument panel can be processed repeatedly. When the model of the instrument panel is changed, the multiple sets of first insertion rods 25 can be adjusted again according to the above operation.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
