Description

Technical Field

[0001] This utility model relates to the technical field of grinding devices, and in particular to a clamping fixture. Background Technology

[0002] Televisions or computers can be mounted on walls or fixed surfaces using a bracket mechanism. This bracket mechanism includes a mounting plate for mounting the monitor or television. Drilling is required on the mounting plate, and after each drilling operation, the resulting debris must be cleaned up promptly to avoid affecting the surface quality of the next mounting plate.

[0003] Typically, workers use templates or rulers to mark the locations for drilling on the mounting plate, or use drilling fixtures to position and drill the holes. However, in current drilling methods, the mounting plate is usually placed on the fixture, and then manually pressed and fixed before processing. This is not only labor-intensive, but also prone to shifting during processing, leading to substandard drilling results. Utility Model Content

[0004] The purpose of this invention is to provide a clamping fixture. This solves the problems of high labor costs and the tendency for the fixture to shift during processing, leading to substandard results.

[0005] To achieve the above objectives, the present invention employs the following solution: a clamping fixture, comprising a connecting platform, a left clamping device, a right clamping device, a limiting device, and a fixing device. The left clamping device and the right clamping device are respectively provided on the left and right sides of the connecting platform. The left clamping device and the right clamping device are connected to the connecting platform, and the left clamping device and the right clamping device cooperate to clamp and fix the workpiece. The front side of the connecting platform is provided with the limiting device for limiting the front side of the workpiece. The upper end of the left clamping device and / or the right clamping device is provided with a fixing device for fixing the workpiece. The connecting platform is provided with multiple discharge holes. The fixing device is provided at the upper end of the left clamping device; the fixing device includes a movable component and a clamping block. A fixing post is provided at the upper end of the left clamping device, the movable component is provided at the upper end of the fixing post, and the clamping block is provided at the lower end face of the movable component. The movable component is driven to cause the clamping block to press against the upper end face of the workpiece to fix the workpiece.

[0006] In this solution, left and right clamping devices are used to fix the left and right sides of the workpiece. A limiting device then limits the front end of the workpiece to prevent it from moving forward. A fixing device presses down on the top of the workpiece to prevent positional shifts. This ensures the workpiece remains stationary during processing, making machining more accurate and convenient as it eliminates the need for manual pressing. A movable component drives a clamping block to press against the top surface of the workpiece, further preventing movement and ensuring a more stable position.

[0007] Preferably, the left clamping device is fixed to the upper end of the connecting platform, and a sliding groove is provided on the right side of the connecting platform, in which the right clamping device is slidably disposed.

[0008] In this solution, the sliding right clamping device can be used to accommodate workpieces of different widths and sizes, thus improving adaptability.

[0009] Preferably, the left clamping device and the right clamping device are fixed blocks.

[0010] As a further preferred embodiment, the sidewall of the sliding groove is provided with an elastic element, the other end of which is connected to the right clamping device. The bottom wall of the sliding groove is provided with a plurality of insertion holes, into which pins can be inserted. The insertion of the pins restricts the reset of the elastic element.

[0011] In this design, the increased distance between the left and right clamping devices allows for better workpiece fixation. After fixation, the pin is inserted into the socket to prevent the elastic element from continuing to stretch, thus preventing the workpiece from shifting position.

[0012] Preferably, the limiting device is a limiting block, which is located at the upper end of the connecting platform.

[0013] As a further preferred embodiment, two limiting blocks are provided, and the two limiting blocks are respectively located on the left and right sides of the front upper side of the connecting platform.

[0014] In this solution, the front end position of the workpiece is limited and positioned by setting a limit block.

[0015] As a further preferred embodiment, the movable component includes a movable block and a connecting column. The upper end of the fixed column is provided with the movable block, the movable block is hinged to a connecting plate, the lower end of the connecting plate is provided with the connecting column, and the lower end of the connecting column is provided with the clamping block.

[0016] In this solution, a movable block is set to drive the connecting plate to move, which in turn drives the connecting column to move. The connecting column then drives the clamping block to clamp the workpiece.

[0017] Preferably, a counterweight is provided at the lower end of the connecting platform.

[0018] In this solution, by setting a counterweight, the connecting platform can be prevented from moving during processing. Attached Figure Description

[0024] Furthermore, in a preferred embodiment, the left clamping device 2 is fixed to the upper end of the connecting platform 1, and a sliding groove 11 is provided on the right side of the connecting platform 1, within which the right clamping device 3 is slidably disposed. The left clamping device 2 and the right clamping device 3 are fixed blocks. An elastic element 12 is provided on the side wall of the sliding groove 11, and the other end of the elastic element 12 is connected to the right clamping device 3. A plurality of insertion holes 13 are provided on the bottom wall of the sliding groove 11, and pins 14 can be inserted into the insertion holes 13. The insertion of the pins 14 and the pins 14 restrict the repositioning of the elastic element 12.

[0025] Furthermore, as a preferred embodiment, the limiting device 4 is a limiting block, which is located at the upper end of the connecting platform 1. Two limiting blocks are provided, which are located on the left and right sides of the front upper end of the connecting platform 1.

[0026] Furthermore, as a preferred embodiment, a fixing device 5 is provided and located at the upper end of the left clamping device 2. The fixing device 5 includes a movable component 51 and a clamping block 52.

Driving the movable component 51 causes the clamping block 52 to press against the upper end face of the workpiece to fix the workpiece.

[0027] Furthermore, as a preferred embodiment, the movable component 51 includes a movable block 511 and a connecting post 512. The upper end of the fixed post 53 is provided with the movable block 511, the movable block 511 is hinged to the connecting plate 513, the lower end of the connecting plate 513 is provided with the connecting post 512, and the lower end of the connecting post 512 is provided with a clamping block 52.

[0028] Furthermore, as a preferred embodiment, a counterweight 7 is provided at the lower end of the connecting platform 1.

[0029] Specifically, in this embodiment, the connecting platform 1 is a plate-shaped fixed plate. A counterweight 7 is provided at the lower end of the connecting platform 1 so that it can have its own weight and form an operating table without moving during the processing. There are five material feeding holes 6 on the left and right sides, front and back sides and the middle position of the upper end face of the connecting platform 1. A limit device 4 is provided on the front side of the upper end face of the connecting platform 1. The limit device 4 is a bolt-shaped limit block. There are two limit blocks, located on the left and right sides of the same horizontal line. The workpiece is pressed against the limit block to fix its position.

[0030] Specifically, in this embodiment, a left clamping device 2 and a right clamping device 3 are respectively provided on the left and right sides of the upper end face of the connecting platform 1. Both the left clamping device 2 and the right clamping device 3 are fixed blocks. The left clamping device 2 is fixedly connected to the operating platform. A sliding groove 11 with a right-side opening is provided on the right side of the operating platform. An elastic element 12, which is a spring, is provided on the side wall of the sliding groove 11. The other side of the spring is connected to the right clamping device 3. The stretching and rebound of the spring causes the right clamping device 3 to move. When the spring is not stretched, the left clamping device 2 and the right clamping device 3 can clamp smaller workpieces. When the spring is stretched, the distance between the left clamping device 2 and the right clamping device 3 increases, allowing them to clamp larger workpieces. Multiple insertion holes 13 are provided on the bottom wall of the sliding groove 11. A pin 14 can be inserted into each insertion hole 13. When the spring is stretched to the desired position, the pin 14 is inserted into the corresponding insertion hole 13 to fix the spring, so that the right clamping device 3 will not continue to move to the right under the influence of the workpiece.

[0031] Specifically, in this embodiment, a fixing device 5 is provided at the upper end of the left clamping device 2, a fixing post 53 is provided at the upper end of the left clamping device 2, a movable block 511 is provided at the upper end of the fixing post 53, a connecting plate 513 is hinged to the movable block 511, a connecting post 512 is provided at the lower end of the connecting plate 513, and a pressing block 52 is provided at the lower end of the connecting post 512. After the workpiece is placed, the movable block 511 is pried open, and the movable block 511 drives the connecting plate 513 to move. The connecting plate 513 drives the connecting post 512 and the pressing block 52 to move and descend, pressing the pressing block 52 onto the upper end surface of the workpiece to fix it. When disassembling, the movable block 511 is pried open in the opposite direction, and the movable block 511 drives the pressing block 52 to rise and detach from the workpiece, thereby disassembling the workpiece.

[0032] Specifically, in this embodiment, the increased distance between the left clamping device 2 and the right clamping device 3 can better fix the workpiece. After fixing, the pin 14 is inserted into the socket 13 so that the elastic element 12 will not continue to stretch, so that the position of the workpiece will not move.

[0033] Specifically, in this embodiment, the left and right sides of the workpiece are fixed by setting the left clamping device 2 and the right clamping device 3. The sliding left clamping device 2 or the right clamping device 3 can be used to adapt to workpieces of different widths. The limiting device 4 limits the front end of the workpiece to prevent it from moving forward. The fixing device 5 presses on the upper end of the workpiece to prevent it from shifting in position. This makes the workpiece position not move during processing, making the processing more accurate. Since no manual pressing is required, the processing is more convenient. It can adapt to workpieces of different sizes, making it more adaptable.

[0034] Specifically, in this embodiment, a limiting block is used to restrict and position the front end of the workpiece. A movable component 51 drives a clamping block 52 to move, thus clamping the workpiece to its upper surface and preventing any positional movement, resulting in a more fixed position. A movable block 511 drives a connecting plate 513, which in turn drives a connecting column 512, which in turn drives the clamping block 52 to clamp the workpiece. A counterweight 7 is used to prevent the connecting platform 1 from shifting during processing.
