Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a stepped surface fixing clamp. Background Art

[0002] A fixture is a device used to fix the object to be processed in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. It is also called a clamp. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process in the process can be called a fixture.

[0003] When faced with the clamping problem of special-shaped molds, such as stepped molds, existing clamps have limitations due to the single clamping method of traditional clamps. Due to the complex structure of such molds, each step connection requires more precise and stable support, and traditional single-point clamping is difficult to meet this requirement, which can easily lead to loose clamping and mold displacement during subsequent processing, which not only affects the overall quality of the mold, but also significantly reduces production efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the single clamping method of the traditional clamp in the prior art has limitations. When clamping a stepped mold, single-point clamping easily leads to loose clamping, resulting in mold displacement during subsequent processing. For this reason, we propose a stepped surface fixing clamp.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical solution: a stepped surface fixing clamp, comprising a clamp seat, a through groove is opened on the top of the clamp seat, a plurality of connecting rods are slidably connected inside the through groove, a U-shaped clamping block is installed at the bottom of the connecting rod, a fastening plate is slidably connected to the surface of the connecting rod, the fastening plate is located at the top of the clamp seat, a fastening nut is threadedly connected to the top of the fastening nut, a rotating shaft is fixedly connected to the top of the rotating shaft, and a control handle is slidably connected to the surface of the rotating shaft.

[0008] Preferably, a movable clamping block is installed inside the U-shaped clamping block, one side of the movable clamping block is fixedly connected to a control rod, and an end of the control rod away from the movable clamping block passes through one side of the U-shaped clamping block and is fixedly connected to the control block, a plurality of limit grooves are provided on the top of the control rod, and guide rods are installed on the top and bottom of one side of the movable clamping block, and one end of the guide rod away from the movable clamping block is fixedly connected to a connecting plate, a second through hole for use with the control rod is provided on the surface of the connecting plate, a shell is installed on one side of the connecting plate, the interior of the shell is slidably connected to the limit block, the bottom of the limit block is provided with a bevel, the limit block is plugged into the inside of the limit groove, a toggle rod is installed on one side of the limit block, and a limit slide groove for use with the toggle rod is provided on one side of the shell.

[0009] Preferably, a spring is sleeved on the surface of the control rod, one end of the spring is fixedly connected to the connecting plate, and the other end of the spring is fixedly connected to the U-shaped clamping block.

[0010] Preferably, both sides of the limit block are fixedly connected with sliders, and both sides inside the shell are fixedly connected with guide rails used in conjunction with the sliders.

[0011] Preferably, a first clamping piece is installed on one side inside the U-shaped clamping block, and a second clamping piece is installed on a side of the movable clamping block away from the control rod.

[0012] Technical effects and advantages of the utility model:

[0013] In the utility model, multi-point clamping is performed by multiple U-shaped clamping blocks, making the clamping more secure and ensuring that the mold will not be displaced during subsequent processing, thereby ensuring the overall quality of the mold and indirectly improving production efficiency.

[0022] Reference Figure 1-Figure 3 As shown, the utility model provides a technical solution: a stepped surface fixing fixture, including a fixture seat 1, a through slot 2 is opened on the top of the fixture seat 1, a plurality of connecting rods 3 are slidably connected inside the through slot 2, a U-shaped clamping block 4 is installed at the bottom of the connecting rod 3, a fastening sheet 5 is slidably connected to the surface of the connecting rod 3, the fastening sheet 5 is located at the top of the fixture seat 1, a fastening nut 6 is threadedly connected to the top of the connecting rod 3, a rotating shaft 7 is fixedly connected to the top of the fastening nut 6, a control handle 8 is slidably connected to the surface of the rotating shaft 7, gaskets 9 used in conjunction with the fastening sheet 5 are installed on both sides of the top of the fixture seat 1, and when the user needs to clamp the stepped mold, the stepped mold is placed inside the U-shaped clamping block 4 The U-shaped clamping block 4 is then moved to clamp and fix each step position respectively. When the U-shaped clamping block 4 is moved to a suitable position, the fastening nut 6 is rotated by the rotating shaft 7 to move the fastening nut 6 downward through the thread line to tighten the fastening sheet 5, thereby fixing the position of the connecting rod 3 to ensure that the U-shaped clamping block 4 firmly clamps the mold. Multi-point clamping is performed by multiple U-shaped clamping blocks 4 to make the clamping more secure and ensure that the mold will not be displaced during subsequent processing to ensure the overall quality of the mold and indirectly improve production efficiency. By controlling the setting of the handle 8, the friction between the user's hand and the rotating shaft 7 is reduced, thereby facilitating operation.

[0023] Reference Figure 2 As shown, in this embodiment: guide rods 10 are installed on both sides of the inside of the clamp seat 1, and a first through hole 11 is opened on the surface of the U-shaped clamping block 4 for use with the guide rod 10. Through the sliding connection between the guide rod 10 and the first through hole 11, the movement of the U-shaped clamping block 4 is oriented and stabilized, preventing the U-shaped clamping block 4 from shaking when it is moved only by the connecting rod 3.

[0024] Reference Figure 2 and Figure 4 As shown, in this embodiment: a movable clamping block 12 is installed inside the U-shaped clamping block 4, a control rod 13 is fixedly connected to one side of the movable clamping block 12, an end of the control rod 13 away from the movable clamping block 12 passes through one side of the U-shaped clamping block 4 and is fixedly connected to the control block 14, a plurality of limit grooves 15 are provided on the top of the control rod 13, a guide rod 26 is installed on the top and bottom of one side of the movable clamping block 12, an end of the guide rod 26 away from the movable clamping block 12 is fixedly connected to a connecting plate 27, a second through hole 28 used in conjunction with the control rod 13 is provided on the surface of the connecting plate 27, a shell 16 is installed on one side of the connecting plate 27, and the internal sliding connection of the shell 16 A limit block 17 is connected, a bevel 18 is provided at the bottom of the limit block 17, the limit block 17 is plugged into the inside of the limit groove 15, a toggle rod 19 is installed on one side of the limit block 17, and a limit slide groove 20 used in conjunction with the toggle rod 19 is provided on one side of the shell 16. When the mold is placed inside the U-shaped clamping block 4, the control block 14 is pushed to make the control rod 13 drive the movable clamping block 12 to clamp the mold. After the movable clamping block 12 clamps the mold, the limit block 17 is driven to move downward by controlling the toggle rod 19, so that the limit block 17 is inserted into the inside of the limit groove 15, so that the position of the control rod 13 is fixed, so as to achieve the purpose of clamping molds of different sizes.

[0025] Reference Figure 2 and Figure 4 As shown, in this embodiment: a spring 21 is sleeved on the surface of the control rod 13, one end of the spring 21 is fixedly connected to the connecting plate 27, and the other end of the spring 21 is fixedly connected to the U-shaped clamping block 4. Through the setting of the spring 21, when the mold needs to be removed, the limit block 17 is driven to move upward and disengage from the inner diameter of the limit groove 15 by controlling the toggle rod 19, thereby releasing the limit on the control rod 13, and then the elastic force generated by the spring 21 drives the connecting plate 27 to move, and the movement of the connecting plate 27 drives the guide rod 26 to drive the movable clamping block 12 to move, thereby releasing the clamping of the mold, thereby facilitating the user to quickly remove the mold.

[0026] Reference Figure 5As shown, in this embodiment: sliders 22 are fixedly connected to both sides of the limit block 17, and guide rails 23 used in conjunction with the sliders 22 are fixedly connected to both sides of the shell 16. Through the sliding connection between the sliders 22 and the guide rails 23, the moving trajectory of the limit block 17 is limited to prevent the limit block 17 from offset when moving.

[0027] Reference Figure 2 As shown, in this embodiment: a first clamping piece 24 is installed on one side inside the U-shaped clamping block 4, and a second clamping piece 25 is installed on the side of the movable clamping block 12 away from the control rod 13. The arrangement of the first clamping piece 24 and the second clamping piece 25 can prevent the movable clamping block 12 from scratching the surface of the mold when clamping the mold, and at the same time can increase the friction force during clamping, making the clamping more stable. At the same time, the first clamping piece 24 and the second clamping piece 25 are both made of rubber.

[0028] Working principle: when the user needs to clamp the stepped mold, the stepped mold is placed inside the U-shaped clamping block 4, and then the U-shaped clamping block 4 is moved so that the U-shaped clamping block 4 clamps and fixes each step position respectively. When the U-shaped clamping block 4 moves to a suitable position, the fastening nut 6 is rotated by the rotating shaft 7, so that the fastening nut 6 moves downward through the thread line and the fastening sheet 5 is pressed, so that the position of the connecting rod 3 is fixed to ensure that the U-shaped clamping block 4 firmly clamps the mold. Multi-point clamping is performed by multiple U-shaped clamping blocks 4 to make the clamping more secure and ensure that the mold will not be displaced during subsequent processing to ensure the overall quality of the mold and indirectly improve production efficiency. By controlling the setting of the handle 8, the friction between the user's hand and the rotating shaft 7 is reduced, thereby facilitating operation. The sliding connection between the guide rod 10 and the first through hole 11 plays a role in directing and stabilizing the movement of the U-shaped clamping block 4, preventing the U-shaped clamping block 4 from shaking when it is only moved by the connecting rod 3.
