Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a tooling for processing automotive window lift rails. Background Technology

[0002] Because the car window regulator rail is an irregularly shaped curved component, it cannot be fixed using planar tooling, and fixing holes cannot be directly drilled into its irregular surface. The existing solution is to first drill the holes, then shape the rail using a rolling mill, and finally manually deburr and enlarge the holes. This processing method has a high scrap rate, and the rolling mill bending process affects the accuracy and size of the pre-drilled holes, requiring manual intervention. The cost of labor and materials is too high, making it uncompetitive in the market.

[0003] Chinese utility model patent CN210816863U discloses a bending fixture for car window guide rails. The fixture uses a first positioning block and a second positioning block to position the guide rail. Then, a first cylinder drives a bending die to move towards a bending punch, subjecting the guide rail to pre-bending under the pressure of the bending die and punch. Next, a third cylinder drives a pressure block to move vertically downwards, pressing it onto the guide rail for further compression. Finally, a third cylinder drives a second positioning block to slide along a guide groove, further bending the guide rail. However, this fixture can only process one guide rail at a time, which can easily lead to problems such as excessive tolerances in the separate processing of the left and right guide rails of the car window, making assembly impossible. Utility Model Content

[0004] The purpose of this utility model is to provide a machining fixture for automotive window lift rails. By machining the left and right guide rails symmetrically, product consistency is improved, and the problem of assembly failure due to excessive tolerance caused by separate machining is reduced.

[0005] The above-mentioned objective of this utility model is achieved through the following technical solution: a machining fixture for automobile window lifting guide rail, including a machine tool connecting plate, and further including: bending fixture and drilling fixture; The bending fixture includes: The first base plate is fixed on the machine tool connecting plate, and a bending die is provided on it. The bending die has a first working area symmetrically distributed on its left and right sides. The drilling fixture includes: The second substrate is disposed on one side of the first substrate, and a positioning template is disposed thereon. The positioning template has second working areas symmetrically distributed on its left and right sides. Each work area is equipped with a clamping component on one side, which is used to fix the workpiece in the corresponding work area.

[0006] Preferably, the first working area has a forming surface that curves downwards in an arc and a vertical first pressing surface.

[0007] Preferably, the bending die is configured as two sections, which are distributed at an interval between each other.

[0008] Preferably, the second working area has a horizontal second pressing surface and a vertical third pressing surface, wherein the third pressing surface is an arc-shaped surface that curves laterally.

[0009] Preferably, the positioning template is configured as two segments, which are distributed at an interval between each other.

[0010] Preferably, the clamping assembly includes an upper pressure block, a first cylinder for driving the upper pressure block to move up and down, a side pressure block, and a second cylinder for moving the side pressure block horizontally.

[0011] Preferably, the first cylinder is a spinning cylinder.

[0012] Preferably, both sides of the bending die and the positioning die are provided with positioning supports.

[0013] Preferably, the end of the bending die is provided with a cutting and positioning support.

[0014] The beneficial effects of this utility model are: This utility model integrates two sets of tooling onto a machine tool connecting plate, which connects to the machining center's processing table, saving turnaround time and improving equipment utilization. By using symmetrical machining of the left and right guide rails, product consistency is improved, and the problem of assembly failure due to excessive tolerance caused by separate machining is reduced.

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.

[0018] Example: like Figure 1-4 As shown, a machining fixture for automotive window lift rails includes a machine tool connecting plate 1, a bending fixture, and a drilling fixture. like Figure 2 As shown, the bending fixture includes a first base plate 2 and a bending die 4. The first base plate 2 is fixed on the machine tool connecting plate 1, and the bending die 4 is installed in the middle position of the first base plate 2. The first working areas 401 are symmetrically distributed on the left and right sides of the bending die 4.

[0019] The first working area 401 has a forming surface 4011 that is curved downwards in an arc shape and a vertical first pressing surface 4012.

[0020] The bending die 4 is set in two sections, and the two bending dies 4 are distributed at an interval between front and back.

[0021] like Figure 3 As shown, the drilling fixture includes a second base plate 3 and a positioning template 5. The second base plate 3 is disposed on one side of the first base plate 2 and fixed on the machine tool connecting plate 1. The positioning template 5 is mounted on the second base plate 3. The positioning template 5 has a second working area 501 symmetrically distributed on the left and right sides. The second working area 501 has a horizontal second pressing surface 5011 and a vertical third pressing surface 5012. The third pressing surface 5012 is an arc-shaped surface that bends to the side.

[0022] The positioning template 5 is set in two sections, with the two sections of positioning template 5 distributed at an interval between front and back. The third pressing surface 5012 of the two sections of positioning template 5 fits against the arc surfaces at the front and back ends of the workpiece 9b to be drilled.

[0023] Each working area is equipped with a clamping assembly 6 on one side, which is used to fix the workpiece in the corresponding working area. That is, both the first working area 401 and the second working area 501 are equipped with clamping assemblies 6.

[0024] The pressing assembly 6 includes an upper pressing block 601, a first cylinder 603 that drives the upper pressing block 601 to move up and down, a side pressing block 602, and a second cylinder 604 that moves the side pressing block 602 horizontally. The upper pressing block 601 is located above the forming surface 4011 and the second pressing surface 5011, and the side pressing block 602 is located to the side of the first pressing surface 4012 and the third pressing surface 5012.

[0025] Among them, the first cylinder 603 is a spinning cylinder, and the upper pressure block 601 is connected to the piston rod end of the spinning cylinder through a rotating arm; Both sides of the bending die 4 and the positioning die 5 are provided with positioning supports 7, which are used for preliminary positioning when the workpiece 9a to be bent is placed in the first working area 401 and when the workpiece 9b to be drilled is placed in the second working area 501.

[0026] The end of the bending die 4 is provided with a cutting and positioning support 8.

[0027] like Figure 4 As shown, the bending fixture and drilling fixture are processed simultaneously. After processing is completed, the system automatically opens the cylinder, placing the workpiece processed by the bending fixture (i.e., the workpiece 9b to be drilled) into the drilling fixture, and placing the blank (i.e., the workpiece 9a to be bent) into the bending fixture. After the system is started, the fixture is automatically clamped. After processing is completed, the above steps are repeated.
