Description

Technical Field

[0001] This utility model belongs to the field of tooling and fixtures, specifically relating to a pressure plate used in drilling operations. Background Technology

[0002] In drilling, the pressure plate is an important auxiliary tool. It is mainly used to fix the workpiece and ensure that the workpiece does not shift during the drilling process. By applying appropriate pressure, the pressure plate can fix the workpiece tightly on the worktable, so that the drill bit can drill the required hole in the workpiece, thereby ensuring the accuracy and quality of the drilling.

[0003] The most commonly used pressure plates currently have a flat bottom surface and a through hole. A bolt passes through the through hole and the lower end of the bolt is connected to the worktable. A nut is then screwed onto the bolt. By rotating the nut, the pressure plate can be moved downward to press and position the workpiece below. When drilling is required, in order to improve drilling efficiency, several workpieces are usually stacked on the worktable first. Then, a template is placed on top, and the pressure plate applies downward pressure to the template to position the stacked workpieces.

[0004] However, during the machining process, vibrations during drilling often cause the workpieces to fall off, resulting in significant deviations in the hole position on the bottom workpiece when drilling is finally completed. In severe cases, this can even lead to the scrapping of the workpiece. Therefore, a pressure plate that can increase stability during drilling is needed. Utility Model Content

[0005] The purpose of this invention is to provide a pressure plate that can improve the stability of drilling operations on workpieces.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is a pressure plate for drilling operations, comprising a hanging plate located above a processing platform, a clamping plate disposed between the hanging plate and the processing platform, the clamping plate being vertically movable, the bottom working surface of the clamping plate being in close contact with the workpiece to be processed, and elongated notches and positioning auxiliary components respectively disposed at both ends of the clamping plate, a side stop being disposed within the elongated notch, the side stop being axially connected to the clamping plate, and the upper end of the side stop passing through the hanging plate, a locking rod being disposed on the hanging plate, the locking rod applying downward pressure to the clamping plate when screwed, a locking plate being screwed onto the locking rod, the locking plate being located above the hanging plate, the locking plate being vertically movable, and during this process, the locking plate causing the lower end of the side stop to move towards the workpiece to be processed.

[0007] Furthermore, the positioning auxiliary component includes a long strip-shaped positioning plate connected to the clamping plate, with the positioning plate and the clamping plate extending in the same straight line direction.

[0008] Furthermore, the clamping plate is provided with a sliding groove extending along its length, and a positioning groove is provided on the bottom surface of the sliding groove. The positioning plate is located in the sliding groove and can slide in the sliding groove.

[0009] Furthermore, the positioning plate is provided with a vertical through opening, and a calibration component is provided inside the opening. The calibration component can cooperate with the positioning groove in the slide.

[0010] Furthermore, a threaded opening is provided at the end of the positioning plate away from the clamping plate, and a standard ring is screwed into the threaded opening, with a positioning pin passing through the standard ring.

[0011] Furthermore, a side support plate is axially connected to the side stop, and an end notch extending upward from the lower end is provided on the side stop. The side support plate passes through the end notch and is axially connected to the side stop at its middle position.

[0012] Furthermore, the locking plate includes a lower plate and an upper plate. The lower plate is a conical platform that can move along the axis of the locking rod. The conical platform is movably connected to the upper plate.

[0013] Furthermore, the lower diameter of the conical platform is smaller than the upper diameter, and a vertically penetrating slide is provided on the side of the conical platform, through which the upper end of the side stop can pass.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When performing batch drilling of wheel disc parts, the wheel disc parts can be stacked on the worktable, and then the working surface of the clamping plate is adjusted to contact the uppermost template part. Then, pressure is applied to the clamping plate by the locking rod, and the locking plate locks the locking rod. At this time, the locking plate applies force to the side baffle, so that the side baffle contacts the circumferential surface of the stacked wheel disc parts. In this way, when drilling the stacked wheel disc parts, the wheel disc parts can be prevented from shifting, thereby increasing the accuracy of the drilling process. Attached Figure Description

The components of the embodiments of the present utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. In the embodiments, the components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application.

[0023] See Figures 1 to 6 As shown, a pressure plate for drilling includes a lifting plate 1 and a clamping plate 2. Both the lifting plate 1 and the clamping plate 2 are located above the worktable 3. The lifting plate 1 is connected to the worktable 3 through a support arm 4, forming a gap space between the lifting plate 1 and the worktable 3. The clamping plate 2 is located in the gap space, where stacked wheel disc parts 5 and template parts 6 can be placed. Then, the clamping plate 2 is used to press and position the stacked wheel disc parts to be processed.

[0024] A flat opening 7 is provided on the hanging plate 1, and a translation seat 8 is provided inside the flat opening 7. The translation seat 8 is provided with a standard hole 9 and a locking screw hole 10. A lifting rod 11 passes through the standard hole 9 and can move within the standard hole 9. The lower end of the lifting rod 11 is connected to the clamping plate 2. Specifically, a U-shaped and inverted curved lifting arm 12 is connected to the lower end of the lifting rod 11. The end of the curved lifting arm 12 is axially connected to the clamping plate 2, and a locking rod 13 is screwed into the locking screw hole 10. The locking rod 13 will move axially when rotating, and its lower end will move towards the clamping plate 2. After the stacked wheel discs to be processed are placed in the interval space, the clamping plate 2 is controlled to move downward by the lifting rod 11 so that the working surface of the clamping plate 2 contacts the uppermost template part. Then, by screwing the locking rod 13, the locking rod 13 applies a certain pressure to the clamping plate. At this time, the stacked wheel discs cannot be separated.

[0025] Before tightening the stacked wheel components, several wheel components need to be stacked and aligned. This requires elongated notches 14 and positioning auxiliary components 15 at both ends of the clamping plate 2. The positioning auxiliary components 15 connect to the mold holes on the template component. A side stop 16 is installed inside the elongated notch 14, and the side stop 16 is axially connected to the clamping plate 2. The upper end of the side stop 16 passes through the flat opening 7 on the hanging plate 1, first contacting the circumferential surface of the wheel component. Then, the locking rod 13 is tightened. A locking plate is screwed onto the locking rod 13, and the locking plate is located above the hanging plate 1. The locking plate includes a lower plate. The lower plate 17 consists of a body 17 and an upper plate 18. The lower plate 17 has a central channel, and a limiting protrusion is provided in the central channel of the lower plate 17. The locking rod 13 has a limiting groove extending axially, and the limiting block is located in the limiting groove. At this time, the lower plate 17 can move along the axial direction of the locking rod 13, but the lower plate 17 cannot rotate. Meanwhile, a threaded hole is provided at the center of the upper plate 18, and the locking rod 13 passes through the threaded hole on the upper plate 18, and the two are screwed together. The lower surface of the upper plate 18 has an annular track groove, and the upper surface of the lower plate 17 has at least three T-shaped connecting blocks 19. Both 19 are connected within the track groove. When the upper plate 18 rotates, it can drive the lower plate 17 to move axially, thereby allowing the lower plate 17 to move towards the hanging plate 1. The lower plate 17 is a conical platform with a lower diameter smaller than the upper diameter. A through slide 20 is provided on the side of the conical platform. The upper end of the side stop 16 is located within the slide 20 and contacts the bottom surface of the slide 20. When the lower plate 17 moves vertically, the upper end of the side stop 16 can pass through the slide 20. During this process, the lower plate 17 applies an external supporting force to the upper end of the side stop 16. Since the side stop 16 is axially connected to the clamping plate 2, at this time... The lower end of the side stop 16 moves toward the workpiece to be processed. The side stop 16 is a curved arm. The side stop 16 is provided with an end notch extending upward from the lower end, and a side plate 21 is connected through the end notch. The side plate 21 is located inside the end notch. The middle position of the side plate 21 is axially connected to the side stop 16. At this time, the side plate 21 can be flipped. During its flipping process, the upper part of the side plate 21 can pass through the end notch. In use, the side plate 21 is in a vertical state. The side plate 21 is in contact with the circumferential surface of several stacked wheel parts at the same time. At this time, the wheel parts are limited by the side plate 21.

[0026] A push plate 22 can be installed inside the slide 20. The lower end of the push plate 22 is hinged to the slide 20. A compression return spring 23 is connected between the upper end of the push plate 22 and the slide 20. The upper end of the side stop 16 can contact the push plate 22. While applying force to the upper end of the side stop 16, the lower plate 17 can be moved to close contact with the translation seat.

[0027] Before the wheel disc is positioned by the side stop 16, the position of the hole in the template needs to be determined. The positioning auxiliary component 15 includes a long positioning plate 24. The clamping plate 2 is provided with a groove 25 extending along its length. The bottom surface of the groove 25 is provided with a positioning groove 26. The positioning grooves 26 are arranged at equal intervals along the length of the groove 25. The positioning plate 24 is located in the groove 25 and can slide in the groove 25. At this time, the positioning plate 24 and the clamping plate 2 extend in the same straight line direction. A threaded opening is provided at the end of the positioning plate 24 away from the clamping plate 2. A standard ring 27 is screwed into the threaded opening. A positioning pin 28 passes through the standard ring 27. The positioning pin 28 can be inserted into the mold hole on the template. Then the position of the positioning plate 24 is locked, and the side stop 16 contacts the circumferential surface of the wheel disc. At this time, the clamping plate 2 can be locked, thereby ensuring the position of the mold hole on the template and aligning the stacked wheel discs to be processed with the template.

[0028] When the positioning plate 24 is locked, the positioning plate 24 is provided with a vertical through opening 29. A calibration component is provided in the opening 29. The calibration component includes a calibration seat 30, which is located in the opening. Vertical grooves 31 are provided on two opposite side surfaces in the opening. A flat edge block 32 is provided on the calibration seat 30, which is located in the vertical groove 31. A return spring 33 is connected between the flat edge block 32 and the lower end of the vertical groove 31. A protrusion 34 is provided on the lower surface of the calibration seat 30. When the calibration seat 30 is pressed down until its upper surface is flush with the upper surface of the positioning plate 24, the protrusion 34 is inserted into the positioning groove. A horizontally flipping locking arm 35 is axially connected to the upper surface of the positioning plate 24. After the locking arm is flipped, one end is located above the calibration seat. At this time, the calibration seat 30 cannot be reset, and the positioning plate 24 cannot slide in the groove.

[0029] Additionally, it should be noted that the groove on the clamping plate is located between the two ends of the curved boom, at which point the positioning plate can pass between the two ends of the curved boom.

[0030] Several of these devices can be set on the worktable. When several of these devices are arranged in a circular array, the stability of the disc-shaped workpiece to be processed can be increased.
