Description

Technical Field

[0001] This utility model relates to the field of processing and positioning equipment technology, specifically to a positioning mechanism for an electric car seat adjuster. Background Technology

[0002] The electric seat adjuster is mainly used to control the seat height, forward and backward movement, and backrest angle adjustment. During the production and processing of the adjuster, it needs to be precisely fixed by a positioning mechanism to ensure the processing accuracy of drilling, welding, assembly and other processes.

[0003] Patent CN216940350U discloses a positioning and assembly fixture for an electric car seat adjuster. This electric car seat adjuster, by setting an adjustable positioning structure, enables the assembly fixture to adapt to electric adjusters of different sizes.

[0004] However, when using this patent, the clamping angle of its assembly mechanism is fixed, which can only achieve positioning at a single angle. When different surfaces of the adjuster need to be processed, the position of the adjuster needs to be disassembled and readjusted, which is time-consuming. This not only reduces processing efficiency but may also lead to a decrease in positioning accuracy due to multiple adjustments. In addition, when using processing equipment of different heights or performing different processing steps, there will be different height requirements. The fixed positioning structure is not flexible enough and is not easy to meet processing requirements.

[0005] Therefore, it is necessary to provide a positioning mechanism for an electric car seat adjuster to solve the above problems. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a positioning mechanism for an electric car seat adjuster. By setting a drive component to realize the angle adjustment of the rotating frame, and cooperating with the lifting component to adjust the height of the worktable, it can meet the processing and positioning requirements of the adjuster at multiple angles and heights and adapt to a variety of processing procedures.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is: a positioning mechanism for an electric car seat adjuster, comprising:

[0008] Mounting base, has two;

[0011] A workbench, which is mounted on the rotating frame;

[0012] A clamping assembly, mounted on the upper surface of the worktable, is used to position the seat adjuster.

[0013] Furthermore, a guide groove is provided on the upper side of the fixing block, and the rack is slidably connected to the inside of the guide groove.

[0014] Furthermore, it also includes a lifting assembly, which includes a connecting seat installed in a pre-reserved groove in the middle of the rotating frame. A lead screw is sleeved on the inner side of the connecting seat. The upper end of the lead screw is rotatably connected to the center of the bottom surface of the worktable, and a handwheel is fixedly connected to the lower end of the lead screw.

[0015] Furthermore, the lifting assembly also includes two guide frames. A slider is fixedly connected to one side of the guide frame, and extension frames are fixedly connected to both sides of the rotating frame. A slide rail is fixed to one side of the extension frame. The slider and the slide rail are slidably connected.

[0026] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0027] like Figure 1-4 As shown, this application provides a positioning mechanism for an electric car seat adjuster, including two mounting bases 1. The lower ends of the two mounting bases 1 are welded and fixed with mounting feet 2. The mounting feet 2 are flat and have mounting holes on both sides. The positioning mechanism can be fixed on the processing table by passing bolts through the mounting holes to ensure that the mechanism as a whole does not shake during the processing.

[0028] A rotating frame 6 is rotatably mounted between two mounting bases 1 via a bearing, and can rotate around the axis of the mounting base 1. A drive assembly 3 is mounted on one side of one of the mounting bases 1.

[0029] The drive assembly 3 includes a fixed block 31, which is fixedly connected to the mounting base 1. A mounting block 35 is fixed to one side of the fixed block 31. A cylinder 36 is fixedly mounted to one side of the mounting block 35 by bolts. A sliding block 37 is fixedly connected to the extended end of the cylinder 36 by bolts. A rack 33 is fixed to one side of the sliding block 37. A guide groove 32 is provided on the upper side of the fixed block 31. The rack 33 is slidably connected to the inside of the guide groove 32. The guide groove 32 provides guidance for the rack 33, ensuring that the rack 33 moves smoothly along a straight line.

[0030] A gear 34 is fixed to the shaft end of the rotating frame 6. The gear 34 meshes with the rack 33. When the cylinder 36 drives the rack 33 to reciprocate, it can drive the gear 34 to rotate in both directions, thereby driving the rotating frame 6 to rotate synchronously.

[0031] In this embodiment, by designing the tooth ratio of gear 34 to rack 33, the forward and reverse rotation angle of gear 34 is 90° when rack 33 reciprocates once.

[0032] A worktable 4 is mounted on the rotating frame 6. The worktable 4 is used to place the automotive electric seat adjuster to be processed. A reserved groove 7 is opened in the middle of the rotating frame 6. A lifting assembly 9 is installed in the groove 7. The lifting assembly 9 includes a connecting seat 91. The connecting seat 91 is fixed in the groove 7 by bolts. A lead screw 92 is sleeved on the inner side of the connecting seat 91. The upper end of the lead screw 92 is rotatably connected to the center of the bottom surface of the worktable 4 through a bearing. A handwheel 93 is fixed to the lower end of the lead screw 92. Rotating the handwheel 93 can drive the lead screw 92 to rotate. Through the threaded engagement between the lead screw 92 and the connecting seat 91, the rotational motion is converted into linear motion, thereby realizing the height adjustment of the worktable 4.

[0033] The lifting assembly 9 also includes two guide frames 94. A slider 95 is welded and fixed to one side of the guide frame 94. An extension frame 8 is fixed to both sides of the rotating frame 6. A slide rail 97 is fixed to one side of the extension frame 8 by bolts. The slider 95 and the slide rail 97 are slidably connected to provide stable guidance for the lifting of the worktable 4.

[0034] A bracket 96 is welded and fixed to the upper end of the guide frame 94. The upper end of the bracket 96 is fixedly connected to the bottom surface of the worktable 4 by bolts, which enhances the connection stability between the worktable 4 and the guide frame 94 and prevents the worktable 4 from tilting during the lifting and lowering process.

[0035] A clamping assembly 5 is installed on the upper surface of the workbench 4. The clamping assembly 5 is used to position and fix the electric car seat adjuster. The clamping assembly 5 includes a clamping frame 51 and a pressure seat 54. Both the clamping frame 51 and the pressure seat 54 are connected and fixed to the workbench 4 by screws. The installation position can be adjusted according to the size of the adjuster.

[0036] The upper end of the clamping frame 51 is threadedly connected to a pressing screw 52. The upper end of the pressing screw 52 is fixed with an adjustment handle for easy rotation operation. The lower end of the pressing screw 52 is fixedly connected to a pressing head 53. The pressing head 53 is made of rubber to prevent damage to the surface of the regulator. The pressing head 53 is located directly above the pressure seat 54. When the regulator is placed on the pressure seat 54, rotating the pressing screw 52 moves the pressing head 53 downward, which can cooperate with the pressure seat 54 to achieve a stable clamping of the regulator.

[0037] Working principle: Before use, fix the positioning mechanism on the processing table through the mounting holes of mounting foot 2. According to the height requirements of the processing equipment, turn the handwheel 93 to drive the lead screw 92 to rotate and adjust the height of the worktable 4 to a suitable position. The slider 95 slides along the slide rail 97 to ensure that the worktable 4 rises and falls smoothly. After the adjustment is completed, stop turning the handwheel 93.

[0038] Place the automotive electric seat adjuster to be processed on the pressure seat 54 of the worktable 4, adjust the position of the adjuster so that the processing part is aligned with the processing head of the processing equipment, and then rotate the pressing screw 52 to drive the pressing head 53 to move downward until the pressing head 53 is in close contact with the surface of the adjuster, thereby achieving the clamping and fixing of the adjuster.

[0039] Start cylinder 36, cylinder 36 drives rack 33 to move along guide groove 32, rack 33 drives gear 34 to rotate, which in turn drives rotating frame 6, worktable 4 and clamping adjuster to rotate synchronously. When rack 33 moves to the end of its stroke, gear 34 rotates 90°, adjuster switches to another processing angle, and processing operation at that angle can be performed.

[0040] Once the angle is processed, the control cylinder 36 reverses its movement, driving the rack 33 to move in the opposite direction, which in turn drives the gear 34 and the rotating frame 6 to rotate 90° in the opposite direction. The adjuster returns to the initial angle, allowing for subsequent processing or replacement of the adjuster.

[0041] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
