Description

Technical Field

[0001] This utility model relates to the technical field of sheet metal processing equipment, specifically to a fixture mechanism for sheet metal processing. Background Technology

[0002] In various processing steps of sheet metal parts, a fixture mechanism is generally required to fix them. Some companies use a double-axis lead screw to drive the slide to clamp and fix the sheet metal parts, and then manually rotate the screw to drive the pressure plate to press down and fix the sheet metal parts before processing. However, the method of using the lead screw to drive the pressure plate to move down is relatively troublesome and inefficient, and needs to be improved. Utility Model Content

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] This application discloses a fixture mechanism for sheet metal processing, including a base and a clamping assembly. The clamping assembly includes a dual-axis lead screw, slides, rocker wheels, a pressure plate, and a connecting frame. The dual-axis lead screw is rotatably connected to the base in a horizontal direction. The two slides are slidably connected to the base and connected to the corresponding threaded sections of the dual-axis lead screw. By rotating the dual-axis lead screw, the two slides can move towards or away from each other. A rocker wheel is provided at the end of the dual-axis lead screw. The connecting frame includes a transverse part and longitudinal parts at both ends. The transverse part is telescopic, and the longitudinal parts are slidably connected to the corresponding slides in the longitudinal direction. A pressure plate is provided at the end of the longitudinal part, and a plug-in locking mechanism is provided between the longitudinal part and the slide.

[0005] When in use, place the sheet metal part on the base, then turn the rocker wheel to clamp the sheet metal part with the slide block. Simultaneously, the horizontal part gradually shortens and presses down on the horizontal part to make the pressure plate abut against and fix the sheet metal part. The locking mechanism locks the two together to complete the bidirectional fixation. The operation is convenient and helps to improve efficiency.

[0006] Furthermore, the locking mechanism includes a locking rod and an elastic element. The locking rod is elastically slidably connected to the slide block in the horizontal direction through the elastic element. The longitudinal part of the connecting frame is provided with a locking hole that is inserted and engaged with the end of the locking rod. In use, if the longitudinal part moves down to the point where the locking hole corresponds to the end of the locking rod, the end of the locking rod is inserted into the locking hole under the action of the elastic element to longitudinally limit the connecting frame.

[0007] Furthermore, it also includes an unlocking mechanism, which includes a slider and a connecting rod. The slider is slidably connected to the transverse part of the connecting frame, and the connecting rod connected to the slider is slidably connected to the locking rod. By pushing the slider to both sides, the locking rod can be driven to move through the connecting rod, thereby disengaging from the lock hole and unlocking.

[0008] Furthermore, the longitudinal portion of the connecting frame is covered with a damping layer, which increases resistance and facilitates the connecting frame to stay in the desired position.

[0009] Furthermore, the base includes a base plate and an L-shaped frame. The longitudinal end of the frame is connected to the base plate, and a sliding block is slidably connected to the slot at the transverse end of the frame. The dual-axis lead screw is rotatably connected to the longitudinal end of the frame, facilitating assembly.

[0010] Furthermore, the longitudinal end of the frame is fitted and connected to the insert plate on the base plate and fastened with bolts. Multiple threaded holes are provided at intervals along the longitudinal direction at the longitudinal end of the frame to facilitate adjustment of the height of the frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model improves the structure of the clamping assembly by using a telescopic connecting frame to connect with the pressure plate, which facilitates the quick pressing of sheet metal parts through the pressure plate and helps to improve efficiency. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] In this example, the fixture mechanism for sheet metal processing includes a base and a clamping assembly, wherein the base 1 is as follows: Figure 1 As shown, the device includes a base plate 100 and an L-shaped frame 101. The base plate 100 is a horizontal plate. The longitudinal end of the frame 101 is connected to the base plate 100. The longitudinal end of the frame 101 is fitted and connected to a longitudinally fixed insert plate 102 on the base plate 100. Threaded holes are formed horizontally at the longitudinal ends of the insert plate 102 and the frame 101, and bolts 103 are screwed into the threaded holes to fasten the two. Multiple threaded holes can be formed longitudinally at intervals at the longitudinal ends of the frame to facilitate adjustment of the height of the frame.

[0020] The clamping assembly includes a dual-axis lead screw 8, a slide block 3, a rocker wheel 9, a pressure plate 7, and a connecting frame 2. The dual-axis lead screw 8 is horizontally rotatably connected to the base 1, as shown below. Figure 1 As shown, the dual-axis lead screw 8 is rotatably connected to the longitudinal end of the frame 101. The horizontal end of the frame 101 is formed with a groove. The longitudinal end of the L-shaped slide block 3 is in the groove and is slidably connected to the groove wall. The two slide blocks 3 are connected to the corresponding threaded sections of the dual-axis lead screw 8. By rotating the dual-axis lead screw, the two slide blocks can slide towards each other or away from each other. During the process of sliding towards each other, the sheet metal part in the middle is clamped.

[0021] To facilitate the rotation of the dual-axis lead screw, a rocker wheel 9 can be fixed at the end of the dual-axis lead screw 8, and force can be applied to the rocker wheel to rotate the lead screw.

[0022] In this example, the connecting frame 2 includes a transverse portion 21 and longitudinal portions 22 connected to its two ends. The transverse portion 21 is telescopic, such as a sleeve telescopic type, where the sleeves on both sides engage with the sleeve in the middle. Figure 1 As shown, the sleeves on both sides are connected to the longitudinal section. The longitudinal section 22 is slidably connected to the corresponding slide 3 in the longitudinal direction. For example, the slide 3 has a hole formed along the longitudinal direction, and the end of the longitudinal section 22 passes through the hole and is fixed to the pressure plate 7 below. When the slides move towards each other, the lateral section contracts; when the slides move away from each other, the lateral section extends. Of course, a damping layer 23, such as a rubber layer, can also be covered on the longitudinal section of the connecting frame 2 to increase resistance and facilitate the connecting frame to stay in the desired position.

[0023] In this example, a plug-in locking mechanism is installed between the longitudinal part 22 and the slide block 3. The locking mechanism includes a locking rod 5 and an elastic element 6. The elastic element 6 allows the locking rod 5 to slide elastically with the slide block 3 in the horizontal direction. For example, the longitudinal end of the T-shaped locking rod 5 extends into the cavity formed in the horizontal part of the slide block 3. A spring is fitted at the longitudinal end of the locking rod 5. The spring serves as the elastic element 6, allowing the locking rod 5 and the slide block 3 to form an elastic sliding connection. A lock hole 4 is formed on the longitudinal part 22. When the longitudinal part 22 slides down to correspond to the end of the locking rod 5, the locking rod is inserted into the lock hole to longitudinally limit the longitudinal part. To facilitate unlocking, an unlocking mechanism is added in this example. The unlocking mechanism includes a slider 24 and a connecting rod 25. The slider 24 is slidably connected to the sleeve in the middle of the transverse part 21 of the connecting frame and is in sliding fit. The transverse end of the L-shaped connecting rod 25 is fixed to the slider 24 and its longitudinal end is slidably connected to the locking rod 5. The locking rod 5 passes through the hole formed at the longitudinal end of the connecting rod 25. The predetermined distance between the longitudinal end of the connecting rod and the longitudinal end of the locking rod does not affect the insertion fit between the locking rod and the lock hole. When unlocking is required, push the slider to both sides, and the locking rod will be moved by the connecting rod, thereby disengaging it from the lock hole to achieve unlocking. At this time, the connecting frame can be moved upward.

[0024] When in use, place the sheet metal part on the base, then turn the rocker wheel to clamp the sheet metal part with the slide block. Simultaneously, the horizontal part gradually shortens and presses down on the horizontal part to make the pressure plate abut against and fix the sheet metal part. The locking mechanism locks the two together to complete the bidirectional fixation, which is easy to operate.

All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
