Description

Technical Field

[0001] The utility model belongs to the technical field of machining fixtures, and more specifically, relates to a fixture for machining peripheral holes of a prism seat. Background Art

[0002] like Figure 5 The figure shows a prism holder used in a conventional handheld antifreeze cryostat. During manufacturing, the holder requires a machining center or machine tool to perform surface finishing and peripheral drilling. During processing, the holder requires a fixture to secure the holder. Conventional fixtures typically can only hold one prism holder at a time, requiring a separate fixture for each prism holder. This is inefficient for large-scale prism holder production.

[0003] Therefore, in view of this, the existing structure and defects are studied and improved, and a tooling fixture for machining peripheral holes of a prism seat is provided, in order to achieve the purpose of having more practical value. Utility Model Content

[0004] In order to solve the above technical problems, the present invention provides a fixture for machining peripheral holes of a prism seat, which is achieved by the following specific technical means:

[0005] A fixture for processing peripheral holes of a prism seat includes a positioning block and multiple groups of pull plates. One side of the pull plate is provided with multiple groups of through slots, and each group of through slots is provided with two; clamping jaws are slidably installed in the through slots, and one end of the clamping jaws in each group of through slots is commonly connected to the pull plate. A threaded hole is provided in the center of the pull plate, and a screw is connected through the threaded hole. One end of the screw is rotatably contacted with one side of the positioning block.

[0006] Furthermore, mounting shafts are provided at both left and right ends of the positioning block.

[0007] Furthermore, the positioning block is provided with two mounting holes near each set of through slots, and positioning pins are fixedly inserted in the mounting holes; the positioning pins are installed on a side of the positioning block away from the pull plate.

[0008] Furthermore, the clamping jaw is L-shaped.

[0009] Furthermore, both ends of the pull plate are provided with through holes, fastening screws are installed in the through holes, and one end of the clamping jaws is provided with screw holes that can be connected to the fastening screws.

[0010] Furthermore, the screw is a hexagon socket screw.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The utility model can clamp multiple groups of prism seats on the side of the positioning block at one time by using the pulling plate, the clamping claws and the screws in coordination, so as to ensure that the processing equipment can process multiple groups of prism seats in sequence at one time during processing without stopping the machine for clamping in the middle, which has high processing efficiency and can enable the processing equipment to be in a processing state for a longer time, thereby improving the utilization rate of the processing equipment and reducing the processing cost.

[0020] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] In the description of this utility model, unless otherwise specified, "plurality" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction, and therefore should not be construed as limiting this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances. Example

[0023] As attached Figure 1 To the attached Figure 4 As shown:

[0024] The utility model provides a fixture for processing peripheral holes of a prism seat, comprising a positioning block 1 and multiple groups of pull plates 3, one side of the pull plate 3 is provided with multiple groups of through grooves, and each group of through grooves is provided with two; clamping jaws 4 are slidably installed in the through grooves, one end of the clamping jaws 4 in each group of through grooves is commonly connected to the pull plate 3, a threaded hole is provided in the center of the pull plate 3, and a screw 5 is connected through the threaded hole, and one end of the screw 5 is rotatably contacted and connected with one side of the positioning block 1.

[0025] Among them, the left and right ends of the positioning block 1 are both provided with mounting shafts 2 to facilitate connection with the main shaft of the processing equipment and to facilitate adjustment of the position of the fixture during processing.

[0026] Among them, the positioning block 1 is provided with two mounting holes near each group of through grooves, and a positioning pin 6 is fixedly inserted in the mounting holes; the positioning pin 6 is installed on the side of the positioning block 1 away from the pull plate 3. Through the setting of the positioning pin 6, it can be connected with the positioning hole on one side of the prism seat to achieve precise positioning of the prism seat and improve processing and tightening.

[0027] The clamping jaw 4 is L-shaped so as to quickly and effectively clamp the flange of the prism seat.

[0028] Among them, both ends of the pull plate 3 are provided with through holes, and fastening screws are installed in the through holes. One end of the clamping jaw 4 is provided with a screw hole that can be connected to the fastening screw, so as to facilitate the fast and effective fixing connection of the clamping jaw 4. At the same time, the structure is relatively simple and the production cost is low.

[0029] The screw 5 is a hexagon socket screw, so that the operator can quickly rotate and adjust the screw 5 using a hexagonal wrench.

[0030] The working principle of this embodiment is as follows: when in use, first connect the mounting shaft 2 of the fixture to the main shaft of the processing equipment, then place the prism seat on one side of the positioning block 1, and connect the positioning pin 6 to the positioning hole on one side of the prism seat. Then use a hexagonal wrench to tighten the screw 5 so that the screw 5 drives the pull plate 3 to move away from the positioning block 1, thereby driving the clamping jaw 4 to clamp the flange of the prism seat. Repeat this several times to fix and clamp multiple groups of prism seats. After clamping is completed, processing can begin.
