Description

Technical Field

[0001] This utility model relates to the field of machining tooling technology, specifically to an auxiliary tooling for machining an L-shaped slider of an expansion mold. Background Technology

[0002] A wheel rim, commonly known as a wheel hub, is the component on a wheel that mounts and supports the tire, forming the wheel together with the spokes. It is the foundation for tire assembly and fixation, and is crucial for driving safety. During rim manufacturing, an expansion die is used to precisely expand the initially formed rim blank, ensuring its diameter and surface dimensions meet product design requirements, guaranteeing roundness and accuracy. The L-shaped slider is the core actuating component of the expansion die. Through an "L"-shaped sliding trajectory at a specific angle, it converts the axial linear motion of the die into radial expansion motion, thereby precisely expanding the rim workpiece.

[0003] The L-shaped slider has a pressure plate groove and three oil grooves on each side. The current processing method is to fix the L-shaped slider on the machine tool with a fixture, process one side, and then turn the L-shaped slider over to process the other side. Each time, the L-shaped slider needs to be aligned and positioned. The alignment process requires repeated measurements, which is slow and affects the processing efficiency. Utility Model Content

[0004] This utility model addresses the aforementioned shortcomings of existing technologies by providing an auxiliary tooling for machining L-shaped sliders in expanding molds. It eliminates the need for repeated measurement and alignment, and the fixture can simultaneously clamp two L-shaped sliders, completing the machining of two workpieces on the same side in one clamping, greatly shortening the clamping time and improving clamping efficiency. To achieve the above objectives, this utility model provides the following technical solution: An auxiliary tooling for machining an L-shaped slider in an expansion mold includes a fixture and a gauge. The fixture includes a base plate, a partition plate at the upper end of the base plate, and first stops on both sides of the partition plate. The sidewalls of the first stops are provided with inclined blocks for pressing the L-shaped slider. One end of the partition plate is provided with a second stop for positioning the end of the L-shaped slider. The gauge is used to inspect the pressure plate groove and oil groove of the L-shaped slider.

[0005] Preferably, the first stop block has a first inclined surface on its side wall, the inclined plug has a second inclined surface on its side wall that slides with the first inclined surface, the upper end of the first stop block has a support plate, and the support plate is connected to a clamping bolt that pushes the inclined plug downward along the first inclined surface. Preferably, the upper end of the inclined plug is provided with a sliding groove, and the lower end of the clamping bolt is provided with a pull block that cooperates with the sliding groove. Preferably, the first stop block has a fixing plate on its side wall, a guide plate at one end of the fixing plate, and a guide groove on its side wall that cooperates with the guide plate.

Detailed Implementation The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] like Figure 1 As shown, an auxiliary tooling for machining an L-shaped slider 7 of an expansion mold includes a fixture and a gauge 6. The fixture is used to clamp and position the L-shaped slider 7. A pressure plate groove 701 and an oil groove 702 are machined on the side wall of the L-shaped slider 7. After machining, the gauge 6 is used to detect the machining position of the pressure plate groove 701 and the oil groove 702.

[0013] The fixture includes a base plate 1, a partition plate 5 at the upper end of the base plate 1, a first stop block 2 on both sides of the partition plate 5, and a slanted plug block 3 on the side wall of the first stop block 2 to press the L-shaped slider 7. The slanted plug block 3 pushes the L-shaped slider 7 toward the partition plate 5 and clamps it. A second stop block 4 is provided at one end of the partition plate 5 to position the end of the L-shaped slider 7.

[0014] like Figure 2 , Figure 3 As shown, the first stop block 2 has a first inclined surface 205 on its side wall, and the inclined block 3 has a second inclined surface 303 on its side wall that slides with the first inclined surface 205. The end of the inclined block 3 facing the L-shaped slider 7 is a vertical plane. The upper end of the first stop block 2 has a support plate 201, and the support plate 201 is connected to a clamping bolt 202 that pushes the inclined block 3 downward along the first inclined surface 205.

[0015] A fixing plate 203 is provided on the side wall of the first stop block 2, and a guide plate 206 is provided at one end of the fixing plate 203. A guide groove 302 that cooperates with the guide plate 206 is provided on the side wall of the inclined block 3 to ensure that the inclined block 3 slides along the first inclined surface 205.

[0016] To ensure that the clamping bolt 202 can pull the inclined plug 3 upward, such as Figure 4 As shown, a sliding groove 301 is provided at the upper end of the inclined plug 3, and a pull block 204 that cooperates with the sliding groove 301 is provided at the lower end of the clamping bolt 202. The pull block 204 is a cylindrical structure. When the clamping bolt 202 is rotated, the pull block 204 can move in the sliding groove 301 and can drive the inclined plug 3 to move up and down. like Figure 6As shown, the gauge 6 has a first detection groove 601 and a second detection groove 602 on both sides. The first detection groove 601 and the second detection groove 602 are used to detect the distance between the side wall of the pressure plate groove 701 and the side wall of the L-shaped slider 7. The first detection groove 601 is the minimum allowable tolerance, and the second detection groove 602 is the maximum allowable tolerance. In this utility model, the width of the first detection groove 601 is 22.9±0.02, and the width of the second detection groove 602 is 22.95±0.02. During the inspection, if the first detection groove 601 cannot be inserted but the second detection groove 602 can be inserted, then the pressure plate groove 701 is qualified.

[0017] like Figure 7 As shown, the bottom of the first detection groove 601 and the second detection groove 602 are provided with detection strips 603 for detecting oil grooves 702. There are three detection strips 603 (corresponding to three oil grooves 702). During the detection, the gauge 6 can slide along the pressure plate groove 701 to make the detection strips 603 cooperate with the oil grooves 702. If the detection strips 603 can be inserted into the oil grooves 702, it means that the processing position of the oil grooves 702 is qualified.

[0018] like Figure 5 As shown, during use, the base is aligned and fixed to the machine tool. The fixture can clamp two L-shaped sliders 7 at the same time. The side walls of the two L-shaped sliders 7 can be processed in one clamping. Then, the L-shaped sliders 7 can be flipped to process the other side. When replacing or flipping the L-shaped sliders 7, there is no need to align the base again, which can realize the rapid positioning and clamping of the L-shaped sliders 7.

[0019] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
