Description

Technical Field

[0001] This utility model belongs to the field of automated processing, and specifically relates to a multi-faceted processing and clamping fixture for automated processing of precision components. Background Technology

[0002] In the production process of injection molded parts, traditional processes typically only allow machining one surface at a time and require multiple clamping operations. For example, for some injection molded parts that require machining multiple surfaces, the traditional method requires machining one surface first, then re-clamping to machine another surface. This not only increases the number of clamping operations but also easily leads to the accumulation of errors due to multiple clamping operations, affecting machining accuracy.

[0003] In addition, traditional tooling can only hold one product at a time. After a product at a workstation is finished, the machine tool needs to be stopped to wait for employees to load and unload the product. Frequent machine stops and loading / unloading operations seriously affect production efficiency.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a multi-faceted machining and clamping fixture for automated processing of precision components. By setting up a movable positioning component, a workstation is provided that can process the workpiece on four sides: left, right, top, and front. Furthermore, by setting up several clamping components and a top limiting component, a precise clamping workstation is provided, avoiding frequent loading and unloading and improving production efficiency.

[0006] Technical Solution: To achieve the above objectives, this utility model provides a multi-faceted machining and clamping fixture for automated processing of precision components, including a base, a first back plate, and a second back plate, the first and second back plates standing on the base; a first positioning component is provided in the middle of the first back plate; several movable positioning components are provided on both sides of the first positioning component; the movable positioning component includes a locking screw and a positioning nut; the locking screw passes through the first back plate; the positioning nut is located on the side of the first back plate away from the second back plate and is connected to one end of the locking screw; a positioning element is provided in the middle of the second back plate; several clamping components are provided around the positioning element; several top limiting components are also provided above the positioning element.

[0007] Furthermore, the movable positioning component does not occupy external space, ensuring that the four surfaces to be processed (left, right, top, and front) of the workpiece will not be affected after assembly, thus fulfilling the requirement of multi-faceted processing, reducing the number of assembly adjustments, and improving production efficiency; the first positioning component can provide fixed positioning points, ensuring that the workpiece can be placed in the same position each time, thereby improving the repeatability and consistency of positioning; the precise positioning function of the clamping component can reduce the vibration and shaking of the component during processing, improve the quality of the processed surface, and reduce surface defects and unevenness; Furthermore, the clamping assembly includes a chuck, an adjusting screw, a guide post, and a clamping block. The chuck is connected to a second back plate via the adjusting screw. The guide post is located on the second back plate. The chuck's center passes through the guide post and its position can be adjusted along the guide post's axial direction. The clamping block is located on the second back plate, beside the guide post. The chuck and clamping block cooperate to complete the clamping. By cooperating with the adjusting screw and guide post, the chuck can quickly adjust its position, achieving rapid clamping and release. This significantly shortens the preparation time before processing and the unloading time after processing, improving production efficiency. Simultaneously, the cooperation between the chuck and clamping block ensures that the workpiece will not loosen or shift during processing, guaranteeing processing accuracy.

[0008] Furthermore, the second back plate is also provided with several clamping blocks along its edge. These additional clamping blocks provide multiple fulcrums for horizontal support of the workpiece, ensuring stability during the workpiece machining process.

[0009] Furthermore, the top limiting assembly includes a connecting block and a limiting screw; the connecting block is disposed on the second back plate; the limiting screw is disposed on the connecting block and can be adjusted vertically. The limiting screw can be adjusted vertically, enabling the top limiting assembly to precisely control the workpiece's position in the vertical direction; by adjusting the limiting screw, it can be ensured that the workpiece will not undergo vertical displacement during processing, thereby improving processing accuracy.

[0010] Furthermore, the first positioning component includes a set of positioning posts; the positioning posts are horizontally disposed on the first back plate for positioning before clamping. The horizontally disposed positioning posts on the first back plate can provide accurate initial positioning for the workpiece, making the workpiece positioning process faster.

[0011] Furthermore, the base is also equipped with two sets of support blocks; the support blocks are respectively located beside the first back plate and the second back plate. The support blocks can evenly distribute the load, better support the workpiece to be processed, reduce the possibility of workpiece deformation during processing, and improve production accuracy.

[0012] Furthermore, a reinforcing support block is provided between the first and second back plates and the base; the reinforcing support block is located beside the support block. The reinforcing support block improves the structural stability and vibration resistance of the tooling, enabling the tooling to better maintain its machining accuracy during long-term use.

[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects: 1. This utility model provides a multi-faceted machining and clamping fixture for automated processing of precision components. By setting up a movable positioning component, it provides a workstation that can process the workpiece from four sides: left, right, top, and front, avoiding frequent loading and unloading and improving production efficiency.

[0014] 2. This utility model provides a multi-faceted processing and clamping fixture for automated processing of precision components. Through the setting of several clamping components and a top limiting component, it provides a precise clamping station. The multi-station setting further improves production efficiency.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] In this embodiment, as Figures 1 to 3 This utility model discloses a multi-faceted machining and clamping fixture for automated processing of precision components, including a base 1, a first back plate 2 and a second back plate 3, the first back plate 2 and the second back plate 3 standing on the base 1; a first positioning component 21 is provided in the middle of the first back plate 2; a plurality of movable positioning components 22 are provided on both sides of the first positioning component 21; the movable positioning component 22 includes a locking screw 221 and a positioning nut 222; the locking screw 221 is provided through the first back plate 2; the positioning nut 222 is provided on the side of the first back plate 2 away from the second back plate 3 and is connected to one end of the locking screw 221; a positioning member 31 is provided in the middle of the second back plate 3; a plurality of clamping components 32 are provided around the positioning member 31; a plurality of top limiting components 33 are also provided above the positioning member 31.

[0018] Specifically, a sensor can be integrated on the top of the locking screw 221 to monitor parameters such as locking force and workpiece position in real time, ensuring that the workpiece is always in a stable clamping state during processing, accurately monitoring the positional deviation of the workpiece, and adjusting the workpiece position or processing parameters in a timely manner to improve the accuracy and quality of processing.

[0019] Specifically, soft materials such as rubber and polyurethane foam are added to the clamping surface of the clamping component 32 to increase the friction between the clamping component 32 and the workpiece to be processed, prevent the component from sliding during processing, and reduce the damage caused by clamping. The clamping component 32 is distributed around the positioning component 31 so that the clamping force is evenly distributed on each force point of the workpiece to be processed, avoiding the deformation of the component due to excessive local force.

[0020] In this embodiment, as Figure 3 The clamping assembly 32 includes a chuck 321, an adjusting screw 322, a guide post 323, and a clamping block 324. The chuck 321 is connected to the second back plate 3 via the adjusting screw 322. The guide post 323 is disposed on the second back plate 3. The chuck 321 passes through the guide post 323 in the middle and its position can be adjusted along the axial direction of the guide post 323.

[0021] Specifically, the adjusting screw 322 can preferably use a double-ended thread design. The double-ended thread can move faster when rotating, which can achieve quick adjustment and improve assembly speed.

[0022] In particular, the guide post 323 is designed to be telescopic, and an adjustment device such as a cylinder is added to realize the telescopic extension of the guide post to adapt to workpieces of different heights.

[0023] In this embodiment, as Figure 3 The second back plate 3 is also provided with several clamping blocks 324 along its edge.

[0024] Specifically, clamping blocks 324 are symmetrically arranged along the edge of the second back plate 3 to form a symmetrical support structure, ensuring the balance of the tooling under stress and reducing deformation caused by asymmetrical stress.

[0026] Specifically, textures can be added to the surfaces of the connecting block 331 and the limiting screw 332, or anti-slip materials can be used to perform anti-slip treatment to increase the friction between them and the workpiece and prevent the workpiece from sliding during processing.

[0027] In this embodiment, as Figure 1 The first positioning component 21 includes a set of positioning posts 211; the positioning posts 211 are horizontally arranged on the first back plate 2 for positioning before clamping.

[0028] Specifically, integrating a displacement sensor into the positioning column 211 is a preferred option to monitor the workpiece position in real time and prevent workpiece displacement during processing from affecting processing accuracy.

[0029] In this embodiment, as Figure 1 The base 1 is also provided with two sets of support blocks 11; the support blocks 11 are respectively located on the sides of the first back plate 2 and the second back plate 3.

[0030] Specifically, it is preferable to add rubber or elastic parts to the upper surface of the support block 11 to reduce vibration during the production process and extend the service life of the equipment.

[0031] In this embodiment, as Figure 1 and Figure 3 A reinforcing support block 12 is provided between the first back plate 2 and the second back plate 3 and the base 1; the reinforcing support block 12 is located on the side of the support block 11.

[0032] Specifically, high-strength bolts can be used to install the reinforcing support block 12 between the first back plate 2, the second back plate 3 and the base 1, which is convenient to install and provides a reliable connection.

[0033] The working principle of the above embodiments is as follows: This utility model discloses a multi-faceted machining and clamping fixture for automated processing of precision components. For the first back plate 2, as shown... Figure 4 During assembly, the workpiece is placed on the support block 11 and positioned by the positioning pin 211 and the positioning nut 222; the locking screw 221 is screwed into the screw hole on the workpiece to complete the assembly before processing. For the second backplate 3, as Figure 5 During assembly, the workpiece is placed on the support block 11 and positioned by the positioning component 31; the chuck 321 is adjusted horizontally along the guide post 323 by adjusting the screw 322, and works with the clamping block 324 to apply pressure in the horizontal direction; at the same time, the limit screw 332 is adjusted vertically to limit the position, thus completing the assembly before processing.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
