Description

Technical Field

[0001] This utility model relates to the field of metal sheet processing and positioning technology, specifically a metal sheet processing and positioning fixture. Background Technology

[0002] Metal sheet refers to a plate-shaped material made of metal. It is a common type of workpiece. During the processing and production of metal sheet, positioning fixtures are needed to hold and position the metal sheet to prevent displacement and shaking during deep processing.

[0003] The announcement number "CN218082331U" provides a positioning and clamping device for metal plate manufacturing. In use, the swing component is activated according to the length of the plate. The swing component drives the rotating plates on the left and right sides to rotate inward at the same time. At this time, the clamping rods on the left and right sides will move relative to each other. Then, the clamping plates on the left and right sides will position the plate in the left and right direction. Then, the positioning component is activated according to the width of the plate. The positioning component will position the plate in the front and back direction, thus adapting to the positioning of plates of different sizes.

[0004] However, the above technical solutions and existing technologies have the following drawbacks:

[0005] Although this positioning and clamping device can clamp and position the sheet metal, the swing component makes the connection between the rotating plate and the clamping rod and the mating rod prone to loosening after a period of use. Once there is looseness or play at the connection between the rotating plate and the clamping rod and the mating rod, it will affect the clamping stability of the clamping plate. Therefore, the clamping stability needs to be further improved. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution:

The positioning platform is installed on the upper surface of the support box, and the metal sheet is placed on the upper surface of the positioning platform.

[0011] Preferably, the auxiliary positioning component includes an electromagnetic adsorption seat, a through cavity, a support partition, an electric push rod, a support plate, a support column, and a limiting cavity. A limiting cavity is formed in the middle of the positioning platform. A support plate is inserted into the lower side of the limiting cavity. An electric push rod is installed in the middle of the lower end face of the support plate. Support columns are symmetrically arranged on the front and rear sides of the upper end face of the support plate.

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

[0016] 1.

The reverse-rotating double threaded screw will drive the positioning clamps on the left and right sides to move inward synchronously through the slide to clamp and position the metal plate. Then, by rotating the downward screw forward, it can be lowered to press down and fix the metal plate. Conversely, it can release the clamping and positioning of the metal plate. Since this structure does not have a corresponding swing structure, there will be no loosening during actual use, and the clamping stability is good.

[0024] 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.

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] Example 1:

[0027] A metal sheet processing positioning fixture includes a metal plate body 1, a positioning platform 2, and a support box 3. The positioning platform 2 is installed on the upper surface of the support box 3. The positioning platform 2 can support the clamping components and auxiliary positioning components. The positioning platform 2 is a detachable structure, which facilitates the removal, maintenance, and replacement of the auxiliary positioning components by the staff later. The metal plate body 1 is placed on the upper surface of the positioning platform 2. The metal plate body 1 is made of iron, which facilitates the adsorption and fixation of the electromagnetic adsorption seat 51. A control panel is installed on the right side of the front face of the positioning platform 2. The control panel is connected to the low-speed motor 411, the electric push rod 54, and the electromagnetic adsorption seat 51 through wires. The control panel allows the staff to control the operation of the low-speed motor 411, the electric push rod 54, and the electromagnetic adsorption seat 51 according to the needs.

[0028] The upper surface of the positioning table 2 is provided with a clamping component, which is used to clamp and position the metal plate 1 placed on the upper surface of the positioning table 2 to prevent the metal plate 1 from shifting during the deep processing. The middle position inside the positioning table 2 is provided with an auxiliary positioning component, which is used to adsorb and position the metal plate 1 to further position the metal plate 1.

[0029] The clamping assembly includes a positioning clamping plate 41, a double-threaded lead screw 49, a low-speed motor 411, a transmission worm gear 412, a transmission worm 413, and a slide block 414. The double-threaded lead screw 49 is installed in the middle of the positioning table 2. Slide blocks 414 are installed on both the left and right sides of the annular side of the double-threaded lead screw 49. The slide blocks 414 have internal threaded through holes (not shown in the figure) and the internal threaded through holes mesh with the double-threaded lead screw 49. The external threads on the left and right sides of the annular side of the double-threaded lead screw 49 rotate in opposite directions. When the double-threaded lead screw 49 rotates, it can drive the slide blocks 414 on the left and right sides to move synchronously and in opposite directions through the internal threaded through holes.

[0030] A positioning clamp 41 is provided on the upper end face of the slide 414. The positioning clamp 41 is connected to the slide 414 by welding. The positioning clamp 41 can clamp and position the metal plate 1. A transmission worm gear 412 is provided on the right side of the annular side of the double threaded screw 49. A transmission worm 413 is meshed on the rear side of the annular side of the transmission worm gear 412. The transmission worm 413 is connected to the double threaded screw 49 by welding. A low-speed motor 411 is installed at the lower end of the transmission worm 413. When working, the low-speed motor 411 can drive the double threaded screw 49 to rotate at a low speed through the transmission worm 413 and the transmission worm gear 412. The meshing transmission worm 413 and the transmission worm gear 412 also have self-locking capability.

[0031] An extension plate 42 is inserted into the upper side of the positioning clamp 41. The extension plate 42 supports the pressing screw 43. The pressing screw 43 is installed on the left side inside the extension plate 42. A vertical internal threaded through hole (not shown in the figure) is opened inside the extension plate 42, and the vertical internal threaded through hole engages with the pressing screw 43. The vertical internal threaded through hole allows the forward-rotating pressing screw 43 to apply downward pressing force to the metal plate 1, so as to further position the metal plate 1. An installation screw 48 is installed at the middle position of the upper end face of the positioning clamp 41. The installation screw 48 can install and fix the extension plate 42 inserted inside the positioning clamp 41. An anti-slip plate 44 is provided on the inner wall of the positioning clamp 41. The anti-slip plate 44 is connected to the positioning clamp 41 by adhesive. The anti-slip plate 44 makes the inner wall of the positioning clamp 41 more slip-resistant.

[0032] The upper surface of the positioning table 2 has symmetrical limit grooves 47 on both the left and right sides. The limit grooves 47 facilitate the lateral movement of the slide 414 inside the positioning table 2. Dust-blocking brushes 45 are installed on both the front and rear sides of the inner wall of the limit grooves 47. The dust-blocking brushes 45 can not only protect the upper end of the limit grooves 47 from dust, preventing external dust from falling directly into the annular side of the double threaded screw 49 and the inside of the limit grooves 47, but also will not hinder the lateral movement of the slide 414 during use. The dust-blocking brushes 45 are individually detachable, which facilitates replacement later. A protective cover 46 is installed on the right end face of the positioning table 2. The protective cover 46 is also detachable. The protective cover 46 can not only support and protect the low-speed motor 411, but also protect the transmission worm gear 412 and the transmission worm 413.

[0033] Example 2:

[0034] Based on Embodiment 1, in this embodiment, by energizing the electromagnetic adsorption seat 51 to generate magnetic adsorption force, the metal plate 1 can be further adsorbed and positioned, thereby stabilizing the metal plate 1. When the electric push rod 54 is extended or retracted, the electric push rod 54 can raise and lower the electromagnetic adsorption seat 51 through the support plate 55 and the support column 56, so that the staff can finely adjust the placement height of the metal plate 1 as needed.

[0035] The auxiliary positioning components include an electromagnetic adsorption seat 51, a through cavity 52, a support partition 53, an electric push rod 54, a support plate 55, a support column 56, and a limiting cavity 57. A limiting cavity 57 is formed in the middle of the positioning platform 2. The limiting cavity 57 matches the support plate 55 and can limit the support plate 55 to prevent it from shifting or shaking during lifting and lowering. The support plate 55 is inserted into the lower side of the limiting cavity 57. The support plate 55 is connected to the support column 56 by welding. The support plate 55 can support the support column 56. An electric push rod 54 is installed in the middle of the lower end face of the support plate 55. The electric push rod 54 can drive the support plate 55 to rise and fall during operation.

[0036] Support columns 56 are symmetrically arranged on both sides of the upper end of the support plate 55. The support columns 56 can support the electromagnetic adsorption seat 51. The electromagnetic adsorption seat 51 is installed on the upper end of the support column 56. The electromagnetic adsorption seat 51 is an electromagnet. When the electromagnet is energized, the electromagnetic adsorption seat 51 can adsorb and assist in positioning the iron metal plate 1 in contact. When the power is off, it can release the adsorption and positioning force on the metal plate 1. The upper end of the positioning platform 2 has symmetrical through cavities 52 on both sides of the upper end. The through cavities 52 match the support columns 56 and are connected to the limiting cavity 57. The through cavities 52 facilitate the lifting and lowering of the support columns 56 inside the positioning platform 2. The support box 3 is fixedly connected to the support partition 53. The support partition 53 can not only support the electric push rod 54, but also divide the internal storage space of the support box 3.

[0037] Working Principle: During the processing of metal plate 1, the operator first places the metal plate 1 flat on the upper surface of the positioning table 2. After placement, the operator controls the low-speed motor 411 to rotate forward via the control panel. The forward-rotating low-speed motor 411 drives the double-threaded screw 49 to rotate in reverse via the transmission worm gear 413 and transmission worm wheel 412. The reverse-rotating double-threaded screw 49 drives the slide blocks 414 on both sides to move inward synchronously through the internal threaded through hole. This causes the slide blocks 414 to drive the positioning clamping plate 41 to move inward synchronously to clamp and position the metal plate 1. Then, with the help of an external wrench, the operator rotates the pressing screws 43 on both sides forward to lower them and press down to fix the metal plate 1. During this process, after the operator loosens the mounting screws 48 and the pressing screws 43 with an external wrench, the extension plate 42 can be disassembled so that the operator can decide whether to use the extension plate 42 and the pressing screws 43 to clamp the metal plate 1 according to the clamping requirements. The process involves pressing down for positioning. Once the metal plate 1 is clamped and positioned by the clamping assembly, the electromagnetic adsorption seat 51 can be energized to generate magnetic adsorption force to further adsorb and position the metal plate 1, thus preventing displacement of the metal plate 1 during processing. During the use of the electromagnetic adsorption seat 51, the operator only needs to control the extension and retraction of the electric push rod 54 to raise and lower the electromagnetic adsorption seat 51 through the support plate 55 and support column 56, allowing the operator to fine-tune the placement height of the metal plate 1 as needed. After the metal plate 1 is processed, the operator first stops the operation of the electromagnetic adsorption seat 51, causing it to lose its magnetic adsorption force. Then, the pressing screw 43 is loosened to raise it. Finally, the low-speed motor 411 is reversed, causing the double threaded screw 49 to drive the positioning clamps 41 on both sides to move outward synchronously through the slide 414, thereby releasing the clamping and positioning of the metal plate 1, which can then be removed.
