Description

Technical Field

[0001] This utility model relates to the field of fixing fixture technology, specifically to fixing fixture for glass window lifter rods. Background Technology

[0002] In the production and assembly of automotive window regulators, the tie rod, as a core component of the transmission system, directly affects the performance stability of the regulator due to its machining accuracy and assembly efficiency. Traditional tie rod fixing methods typically have the following problems:

[0003] Low clamping efficiency: Using general-purpose clamps (such as vises or bolt clamps) requires multiple adjustments to the position, making it difficult to achieve rapid positioning and affecting the batch production cycle.

[0004] Insufficient positioning accuracy: The tie rod is a slender rod, and traditional clamps are prone to deformation or displacement due to uneven clamping force, which affects the machining accuracy of subsequent processes such as drilling / welding.

[0005] Poor adaptability: The size differences between different models of tie rods require frequent changes of fixtures, and the existing tooling lacks modular design, which increases changeover time and cost.

[0006] Existing technologies have achieved some improvements by clamping the tie rod with a V-block and cylinder, but these still suffer from complex structures and high maintenance costs. Therefore, there is an urgent need for a tie rod fixing fixture that is simple in structure, reliable in positioning, and adaptable to rapid production changeovers, in order to meet the automotive parts industry's demand for efficient and high-precision machining. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a fixing fixture for the pull rod of a glass window lifter, including a base on which two uprights are vertically installed;

[0009] A pull rod is placed on each of the two stands, and each pull rod has a prism structure at both ends. A pressure plate is installed on the base, and the pressure plate presses against the upper side of the pull rod.

[0010] The tie rod to be processed is placed on two uprights, which support the tie rod and fix it by pressing it against the upper side. The tie rod can be fixed quickly through a simple structure.

[0011] Furthermore, the support includes a frame and a column;

[0012] The base is provided with a sliding groove;

[0013] A column is installed on the bottom surface of the support frame. The column passes through a sliding groove and is connected to a limiting nut. At the same time, the column slides along the sliding groove.

[0014] With adjustable spacing, it can meet the clamping requirements of tie rods of different lengths.

[0015] Furthermore, the support frame is provided with an opening;

[0016] The opening is composed of several slots that increase in size from bottom to top. The outer side of each slot is provided with a body. By providing different slots, the prism matching requirements of the ends of pull rods of different sizes can be met.

[0017] Furthermore, the support frame is threaded, and the two support frames are installed by engaging with a double-ended screw through the thread;

[0018] The bidirectional screw is connected to a mounting base at its middle section, and the mounting base is fixed to the base.

[0019] A bearing is fitted into the middle of the bidirectional screw and installed in the shaft hole of the mounting base. After installation, the bidirectional screw rotates around its own axis.

[0020] Furthermore, a handle is installed at one end of the bidirectional screw. By rotating the handle clockwise, the bidirectional screw is driven to rotate synchronously, thereby moving the two supports away from each other.

[0021] Turn the handle counterclockwise to bring the two stands closer together.

[0022] Furthermore, the base is provided with mounting holes, and an annular groove is provided in the mounting holes. A screw is fitted in the mounting holes, and a pressure plate is installed on the screw.

[0023] The screw end is fitted with a convex ring that mates with the annular groove, and the screw with the mounting shaft rotates around its own axis.

[0024] Furthermore, the prism structures at both ends of the pull rod are fitted into the slots.

[0025] This utility model has the following beneficial effects:

[0026] (1) The pull rod to be processed in this utility model is placed on two uprights. The pull rod is supported by the two uprights and fixed by pressing on the upper side of the pull rod. The pull rod can be fixed quickly through a simple structure.

[0027] (2) The column of this utility model passes through the slide groove and is connected to the limiting nut. At the same time, the column slides along the slide groove. The spacing is adjustable to meet the clamping requirements of different lengths of tie rods.

[0038] Please see Figures 1-5 As shown, this utility model is a fixing fixture for the pull rod of a glass window lifter, including a base 1, on which two uprights 2 are vertically installed;

[0039] Two uprights 2 are equipped with pull rods 3. Both ends of the pull rods 3 are provided with prism structures. A pressure plate 4 is installed on the base 1. The pressure plate 4 is pressed against the upper side of the pull rod 3. The pressure plate 4 has a V-shaped groove, which is locked on the outside of the pull rod 3.

[0040] The tie rod 3 to be processed is placed on two uprights 2. The tie rod 3 is supported by the two uprights 2. At the same time, the tie rod 3 is fixed by pressing it on the upper side. The tie rod 3 can be fixed quickly through a simple structure.

[0041] The support 2 includes a frame 201 and a column 202;

[0042] The base 1 has a sliding groove 101;

[0043] A column 202 is installed on the bottom surface of the upright 201. The column 202 passes through the slide groove 101 and is connected to the limit nut 203. At the same time, the column 202 slides along the slide groove 101.

[0044] With adjustable spacing, it can meet the clamping requirements of pull rods of different lengths.

[0045] The upright 201 has an opening;

[0046] The opening is composed of several slots 2011 that increase in size from bottom to top. A side body 2012 is provided on the outside of the slots. The side body 2012 is used to axially limit the prism structure at the end of the tie rod 3. By providing different slots 2011, the prism matching requirements of the ends of tie rods 3 of different sizes can be met.

[0047] The upright 201 is provided with a thread 2013, and the two uprights 201 are installed by cooperating with the double-acting screw 6 through the thread 2013.

[0048] A mounting base 7 is connected to the middle of the bidirectional screw 6, and the mounting base 7 is fixed to the base 1;

[0049] A bearing is sleeved in the middle of the double-ended screw 6 and installed in the shaft hole of the mounting base 7. After installation, the double-ended screw 6 rotates around its own axis.

[0050] A handle 8 is installed at one end of the bidirectional screw 6. By rotating the handle 8 clockwise, the bidirectional screw 6 is driven to rotate synchronously, so that the two supports 2 are moved away from each other.

[0051] Turn the handle 8 counterclockwise to bring the two stands 2 closer together.

[0052] The base 1 is provided with a mounting hole 102, and the mounting hole 102 is provided with an annular groove. A screw 5 is installed in the mounting hole 102, and a pressure plate 4 is installed on the screw 5.
