Description

Technical Field

[0001] This utility model specifically relates to the field of automotive mold processing fixtures, and more specifically to a quick clamping fixture for automotive mold processing. Background Technology

[0002] Automotive mold machining positioning fixtures are key process equipment used to fix workpieces and ensure machining accuracy during mold manufacturing. Their design and application directly affect the dimensional accuracy, surface quality and production efficiency of the mold. The positioning elements of the fixture restrict the degree of freedom of the workpiece, and the clamping device (such as hydraulic pressure plate, pneumatic jaw) applies a stable clamping force to counteract the cutting force, centrifugal force and gravity generated during milling, drilling and other machining processes.

[0003] However, in practice, it has been noted that during positioning, the position of the fixture on the tool table needs to be adjusted according to the size of the mold. Then, the screw mechanism is used to move the ejector pin or jaw of the fixture to the side of the mold. Since the screw structure needs to rotate the lead screw continuously, if the position of the ejector pin or jaw is far from that of the mold, a lot of time is required for rotation, resulting in a long clamping time and thus affecting efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a quick-clamping fixture for automotive mold processing. Through the interaction of a rotating locking tongue and a triangular toothed groove, the movable slide can quickly approach the automotive mold for rapid positioning. Then, with the small-range adjustment of the end-mounted fine-tuning screw, the automotive mold is quickly clamped, reducing the time consumed in clamping the mold and improving clamping efficiency. This solves the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A quick clamping fixture for processing automotive molds includes a machine tool body, on which a workpiece placement table is movably connected via a worktable sliding mechanism, and T-shaped slots are arranged in a rectangular array on the workpiece placement table.

[0007] A horizontal support is also installed above the workpiece placement platform. The horizontal support includes the workpiece placement platform placed above the support frame, and a T-shaped slider that slides in a T-shaped slot is fixedly connected below the support frame. Both ends of the T-shaped slider are threaded with locking screws.

[0008] As a further technical solution of this utility model, the upper part of the support crossbeam is provided with triangular toothed grooves in a rectangular array, and an adjustable clamping seat is also movably connected to the upper part of the support crossbeam.

[0009] The adjustable clamping seat includes a movable slide, with an installation groove on the lower part of the movable slide. A quick-adjusting locking device is movably connected to the inner side of the installation groove, and the end of the quick-adjusting locking device engages with a triangular tooth groove.

[0010] As a further technical solution of this utility model, a clamping top plate is fixedly connected above the movable slide, and a fine-tuning screw is threadedly fitted to the end of the clamping top plate away from the movable slide. One end of the fine-tuning screw is integrally provided with an anti-slip clamping plate, and the other end is fixedly connected with an anti-slip knob.

[0011] As a further technical solution of this utility model, the quick-adjusting locking device includes a rotating locking tongue disposed inside the mounting groove. The end of the rotating locking tongue is provided with a pin hole, and a shaft rod fixedly connected to the movable slide is passed through the pin hole. The end of the rotating locking tongue away from the pin hole is engaged with a triangular tooth groove.

[0012] As a further technical solution of this utility model, the side of the movable slide is also provided with an arc-shaped slide groove, and an adjustment lever is fixedly connected to the side of the rotating lock tongue. The end of the adjustment lever away from the rotating lock tongue extends through the arc-shaped slide groove to the side of the movable slide.

[0013] As a further technical solution of this utility model, the supporting crossbeam is located inside the mounting groove, and a horizontal groove located below the triangular tooth groove is also provided in the supporting crossbeam, and a positioning slider is slidably fitted in the horizontal groove.

[0014] As a further technical solution of this utility model, the positioning slider is provided with locking screws symmetrically at both ends, and the locking screws are respectively symmetrically arranged on both sides of the movable slide block. The end of each locking screw passes through the movable slide block and is threadedly connected to the positioning slider.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model pushes the movable slide block closer to the mold, allowing the movable slide block to slide above the supporting crossbeam. At this time, the rotating locking tongue slides above the triangular tooth groove. Due to the inclined setting of the rotating locking tongue, when the rotating locking tongue is subjected to a reaction force, the end of the rotating locking tongue will be stuck in the triangular tooth groove, preventing the movable slide block from moving in the opposite direction. Furthermore, through the cooperation of the rotating locking tongue and the triangular tooth groove in the mounting groove, the movable slide block can only move towards the side closer to the mold, thereby achieving rapid clamping of the mold and shortening the clamping time.

[0017] 2. In this utility model, the rotating lock tongue is rotated by the adjustment lever provided on the side of the rotating lock tongue, so that the end of the rotating lock tongue rotates from the inside of the triangular tooth groove to the top. Without the obstruction of the rotating lock tongue, the movable slide can slide left and right above the support crossbeam, thereby disassembling the clamped mold, and the movable slide can be moved directly to the maximum position.

[0018] 3. In this utility model, the adjusting clamping seat is quickly moved to the side of the mold. Since the spacing between each triangular tooth groove is the same, there is still a gap between the moving slide and the side of the mold. Then, the fine-tuning screw is rotated, and through the threaded engagement between the fine-tuning screw and the clamping top plate, the fine-tuning screw is made to fit against the side of the mold. Only a small range of adjustment is needed to quickly clamp molds of different sizes, thereby shortening the time consumed when clamping the mold. Attached Figure Description

Detailed Implementation

[0028] 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.

[0029] Please see Figure 1-7 This utility model provides a quick clamping fixture for automobile mold processing, including a machine tool body 1, a workpiece placement table 3 movably connected to the machine tool body 1 via a worktable sliding mechanism 2, and T-shaped slots 4 arranged in a rectangular array on the workpiece placement table 3.

[0030] A horizontal support 5 is also installed above the workpiece placement platform 3. The horizontal support 5 includes the workpiece placement platform 3 placed above the support crossbeam 51. A T-shaped slider 54 that slides with the T-shaped slot 4 is fixedly connected below the support crossbeam 51. Both ends of the T-shaped slider 54 are threaded with locking screws 55.

[0031] Furthermore, the upper part of the support crossbeam 51 is provided with triangular toothed grooves 53 in a rectangular array, and an adjustable clamping seat 6 is also movably connected to the upper part of the support crossbeam 51.

[0032] The adjustable clamping seat 6 includes a movable slide 61, and an installation groove 63 is provided below the movable slide 61. A quick-adjustment locking device 8 is movably connected to the inner side of the installation groove 63, and the end of the quick-adjustment locking device 8 is engaged with the triangular tooth groove 53.

[0033] Furthermore, a clamping top plate 62 is fixedly connected above the movable slide 61, and a fine-tuning screw 7 is threadedly fitted to one end of the clamping top plate 62 away from the movable slide 61. One end of the fine-tuning screw 7 is integrally provided with an anti-slip clamping plate, and the other end is fixedly connected with an anti-slip knob.

[0034] By adopting the above technical solution, the adjusting clamping seat 6 is quickly moved to the side of the mold. Since the spacing between each triangular tooth groove 53 is the same, there is still a gap between the moving slide 61 and the side of the mold. Then, the fine-tuning screw 7 is rotated. Through the threaded engagement between the fine-tuning screw 7 and the clamping top plate 62, the fine-tuning screw 7 is made to fit against the side of the mold. Only a small range of adjustment is needed to quickly clamp molds of different sizes, thereby shortening the time consumed when clamping the mold.

[0035] Furthermore, the quick-adjusting locking device 8 includes a rotating locking tongue 81 disposed inside the mounting slide 63. The end of the rotating locking tongue 81 is provided with a pin hole 82, and a shaft rod fixedly connected to the movable slide 61 passes through the pin hole 82. The end of the rotating locking tongue 81 away from the pin hole 82 is engaged with the triangular tooth groove 53.

[0036] More specifically, the side of the movable slide block 61 is provided with an arc-shaped slide groove 64, and an adjustment lever 83 is fixedly connected to the side of the rotating locking tongue 81. The end of the adjustment lever 83 away from the rotating locking tongue 81 extends through the arc-shaped slide groove 64 to the side of the movable slide block 61.

[0037] By adopting the above technical solution, the rotating lock tongue 81 is rotated by the adjusting lever 83 provided on the side of the rotating lock tongue 81, so that the end of the rotating lock tongue 81 rotates from the inside of the triangular tooth groove 53 to the top. Without the obstruction of the rotating lock tongue 81, the movable slide 61 can slide left and right above the support crossbeam 51, thereby disassembling the clamped mold and directly moving the movable slide 61 to the maximum position.

[0038] Furthermore, the support crossbeam 51 is located inside the mounting groove 63, and the support crossbeam 51 is also provided with a horizontal groove 52 located below the triangular tooth groove 53, in which a positioning slider 9 is slidably engaged.

[0039] More specifically, the positioning slider 9 has locking screws 10 symmetrically arranged at both ends, and the locking screws 10 are respectively symmetrically arranged on both sides of the movable slide 61. The end of each locking screw 10 passes through the movable slide 61 and is threadedly connected to the positioning slider 9.

[0040] By adopting the above technical solution, the movable slide 61 is pushed closer to the mold, so that the movable slide 61 slides above the support crossbeam 51. At this time, the rotating locking tongue 81 slides above the triangular tooth groove 53. Since the rotating locking tongue 81 is set at an angle, when the rotating locking tongue 81 is subjected to a reaction force, the end of the rotating locking tongue 81 will be stuck in the triangular tooth groove 53, so that the movable slide 61 cannot move in the opposite direction. Then, through the cooperation of the rotating locking tongue 81 and the triangular tooth groove 53 connected in the mounting groove 63, the movable slide 61 can only move towards the side closer to the mold, thereby realizing the rapid clamping of the mold and shortening the clamping time.

[0041] Furthermore, the movable slide 61 and the clamping top plate 62 are integrally provided with triangular ribs at the included angle position, and the triangular ribs are located at both ends of the fine-tuning screw 7. The triangular ribs reinforce the included angle between the movable slide 61 and the clamping top plate 62, thereby improving the structural strength.

[0042] Furthermore, the mounting groove 63 is stepped, and the rotating locking tongue 81 is inclined inside the mounting groove 63, so that the movable slide 61 can only move in one direction due to the inclination of the mounting groove 63.

[0043] The working principle of this utility model is as follows: First, adjust the position of the support crossbeam 51 above the workpiece placement platform 3. As the support crossbeam 51 moves above the workpiece placement platform 3, the T-shaped slider 54 below the support crossbeam 51 will slide in the T-shaped slot 4 at the appropriate position. For fixing, simply rotate the locking screw 55. Through the threaded engagement between the locking screw 55 and the T-shaped slider 54, the end of the locking screw 55 is pressed against the T-shaped slot 4. Then, place the car mold above the support crossbeam 51 and push the movable slide block 61 towards the car mold quickly. During the movement, the rotating locking tongue 81, which is movably connected in the mounting groove 63, will slide on the triangular toothed groove 53. Due to the inclined setting of the rotating locking tongue 81, when the movable slide block 61 approaches the mold, the end of the rotating locking tongue 81 will slide along the inclined triangular toothed groove 53. Rotate upwards until the end of the triangular toothed groove 53 passes through the next triangular toothed groove 53. Quickly move the movable slide 61 to the side of the mold, then rotate the fine-tuning screw 7. Through the threaded engagement between the fine-tuning screw 7 and the clamping top plate 62, the end of the fine-tuning screw 7 clamps the car mold. At this time, the reaction force on the movable slide 61 is transmitted to the rotating locking tongue 81. Due to the inclined setting of the rotating locking tongue 81, the end of the rotating locking tongue 81 is stuck in the triangular toothed groove 53, thereby quickly clamping the car mold. To disassemble, first loosen the fine-tuning screw 7, and then rotate the end of the rotating locking tongue 81 above the triangular toothed groove 53 by adjusting the lever 83. This allows the movable slide 61 to be moved in the opposite direction and quickly released. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.
