Description

Technical Field

[0001] The utility model relates to the technical field of part processing and fixing, in particular to a workbench fixture for part processing that is convenient to adjust. Background Technique

[0002] A workbench fixture for part processing refers to equipment used to fix, position, and clamp workpieces. There are many types and forms of workbench fixtures, which can be selected according to factors such as the shape, size, material, and processing technology of the workpiece. Common workbench fixtures include chucks, fixtures, fixture racks, fixture tables, fixture gaskets, etc. The function of the workbench fixture is to improve processing accuracy and efficiency, reduce errors and waste during the processing process, and improve the quality and stability of products.

[0003] According to the workbench fixture for part processing that is convenient to adjust provided by the publication number: CN219485443U, the other end of the lead screw of this workbench fixture extrudes the movable plate to slide on the outer walls of the two limit plates, so that the movable plate approaches the part and presses the part against the side of the central plate to clamp and fix the part. Such a design makes the fixture convenient to adjust the spacing, facilitates pressing against parts of different sizes, and observes the width or length of the part through the scale embedded on the upper surface of the limit plate, thereby greatly improving the functionality of the workbench fixture.

[0004] Based on the retrieval of the above patent and the combination with the equipment in the prior art, it is found that when the above equipment is applied, although it can solve the problem that different types and specifications of parts require the replacement of different models of fixtures during the processing of workbench fixtures in the current market, which is likely to increase the purchase cost of workbench fixtures.

[0005] However, in the actual use process, the above equipment does not have a structure to assist the operator in fixing the workpiece. As a result, when the operator needs to clamp the workpiece multiple times, the operator needs to continuously manually rotate the lead screw to press and fix the workpiece. This fixing method is too dependent on the operator, resulting in excessive fatigue of the operator. Content of the Utility Model

[0006] To solve the problems raised in the above background technique, the purpose of the present utility model is to provide a workbench fixture for part processing that is convenient to adjust, which has the advantage of auxiliary fixation, and solves the problem that the above equipment does not have a structure to assist the operator in fixing the workpiece. As a result, when the operator needs to clamp the workpiece multiple times, the operator needs to continuously manually rotate the lead screw to press and fix the workpiece. This fixing method is too dependent on the operator, resulting in excessive fatigue of the operator.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A workbench fixture for part processing that is easy to adjust, including a base and a pressing plate. The right side of the top of the base is fixedly connected with a positioning plate. The pressing plate is arranged on the front side of the top of the base. An installation hole is opened inside the positioning plate, and an infrared sensor is fixedly installed inside the installation hole. The front of the base is fixedly connected with a controller, and the controller is electrically connected to the infrared sensor through a wire. The left side of the pressing plate is fixedly connected with a moving mechanism, and the right side of the pressing plate is fixedly connected with a limiting component.

[0008] Preferably, the moving mechanism includes a moving block. The moving block is fixedly connected to the left side of the pressing plate. A lead screw is threadedly connected inside the moving block. The front end of the lead screw is fixedly connected with a driving motor, and the driving motor is electrically connected to the controller through a wire.

[0009] Preferably, the limiting component includes a limiting block. The limiting block is fixedly connected to the right side of the pressing plate. A limiting rod is slidably connected inside the limiting block.

[0010] Preferably, an installation groove is opened on the back of the pressing plate, and a pressure sensor is fixedly installed inside the installation groove. The pressure sensor is electrically connected to the controller through a wire.

[0011] Preferably, both the front side and the rear side of the surface of the lead screw are movably connected with a support plate through bearings, and the right side of the support plate is fixedly connected to the base.

[0012] Preferably, the front side of the front support plate is fixedly connected with an installation disk, and the driving motor is fixedly installed on the front of the installation disk.

[0013] Preferably, both the front end and the rear end of the limiting rod are fixedly connected with a support block, and the left side of the support block is fixedly connected to the base.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. The utility model is provided with a positioning plate, an infrared sensor and a controller. When an operator needs to fix a workpiece for processing, when the operator fits the workpiece against the positioning plate and blocks the detection end of the infrared sensor, the infrared sensor will transmit data to the controller through a wire, enabling the controller to start the moving mechanism. As a result, the moving mechanism drives the pressing plate to press and fix the workpiece, thus ensuring the convenience for the operator to fix the workpiece. It solves the problem that the above-mentioned device does not have a structure to assist the operator in fixing the workpiece. Consequently, when the operator needs to clamp the workpiece multiple times, the operator has to continuously manually rotate the screw rod to press and fix the workpiece. This fixing method is overly dependent on the operator, leading to excessive fatigue for the operator, and achieving the effect of auxiliary fixation.

[0016] 2. The utility model is provided with a moving mechanism. When the workpiece is placed against the positioning plate and blocks the detection end of the infrared sensor, the infrared sensor will transmit data to the controller through a wire, enabling the controller to start the driving motor. Then, the output end of the driving motor drives the screw rod to rotate, and the rotating screw rod drives the moving block to move. Thus, the moving block drives the pressing plate to move towards the position of the workpiece, enabling the pressing plate to press and fix the workpiece, and allowing the operator to clamp and fix the workpiece without manual operation, ensuring the convenience for the operator to clamp and fix.

[0017] 3. The utility model is provided with a limiting component. When the moving block drives the pressing plate to move, the pressing plate drives the limiting block to move on the surface of the limiting rod, so that the limiting block and the limiting rod limit and guide the moving pressing plate and moving block, preventing the pressing plate and the moving block from rotating automatically when the screw rod rotates.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1 to 3 shown, a work fixture for part processing that is convenient to adjust provided by the present invention includes a base 1 and a pressing plate 2. A positioning plate 3 is fixedly connected to the right side of the top of the base 1. The pressing plate 2 is arranged on the front side of the top of the base 1. An installation hole 4 is opened inside the positioning plate 3, and an infrared sensor 5 is fixedly installed inside the installation hole 4. A controller 6 is fixedly connected to the front of the base 1. The controller 6 is electrically connected to the infrared sensor 5 through a wire. A moving mechanism 7 is fixedly connected to the left side of the pressing plate 2, and a limiting component 8 is fixedly connected to the right side of the pressing plate 2.

[0024] Referring Figure 3 to, the moving mechanism 7 includes a moving block 71. The moving block 71 is fixedly connected to the left side of the pressing plate 2. A lead screw 72 is threadedly connected inside the moving block 71. The front end of the lead screw 72 is fixedly connected to a driving motor 73. The driving motor 73 is electrically connected to the controller 6 through a wire.

[0025] As a technical optimization scheme of the present invention, by setting the moving mechanism 7, when the workpiece fits against the positioning plate 3 and blocks the detection end of the infrared sensor 5 for placement, the infrared sensor 5 will transmit data to the controller 6 through the wire, causing the controller 6 to start the driving motor 73. Thereby, the output end of the driving motor 73 drives the lead screw 72 to rotate, and then the rotating lead screw 72 drives the moving block 71 to move, so that the moving block 71 drives the pressing plate 2 to move towards the position of the workpiece, enabling the pressing plate 2 to press and fix the workpiece, ensuring that the operator can clamp and fix the workpiece without manual operation, and guaranteeing the convenience of the operator's clamping and fixing.

[0026] Referring Figure 3 to, the limiting component 8 includes a limiting block 81. The limiting block 81 is fixedly connected to the right side of the pressing plate 2. A limiting rod 82 is slidably connected inside the limiting block 81.

[0027] As a technical optimization scheme of the present invention, by setting the limiting component 8, when the moving block 71 drives the pressing plate 2 to move, the pressing plate 2 will drive the limiting block 81 to move on the surface of the limiting rod 82, so that the limiting block 81 and the limiting rod 82 limit and guide the moving pressing plate 2 and moving block 71, avoiding the situation where the pressing plate 2 and the moving block 71 rotate self - centrically when the lead screw 72 rotates.

[0028] Reference Figure 3 , an installation groove 9 is formed on the back surface of the pressing plate 2, and a pressure sensor 10 is fixedly installed inside the installation groove 9. The pressure sensor 10 is electrically connected to the controller 6 through a wire.

[0029] As a technical optimization scheme of the present utility model, by providing the installation groove 9 and the pressure sensor 10, the operator first sets the maximum pressing pressure value that the workpiece can withstand in the controller 6. When the pressing plate 2 contacts and presses the workpiece, the pressure sensor 10 will first contact the workpiece, and the pressure sensor 10 will transmit the contact signal through the wire to the inside of the controller 6, so that the controller 6 analyzes the result. When the analysis result reaches the set maximum pressure value, the controller 6 will control the driving motor 73 to stop running, thereby avoiding the situation that the workpiece is pressed in place and over-pressed.

[0030] Reference Figure 3 , the front side and the rear side of the surface of the lead screw 72 are both movably connected to the support plate 11 through bearings, and the right side of the support plate 11 is fixedly connected to the base 1.

[0031] As a technical optimization scheme of the present utility model, by providing the support plate 11, the support plate 11 is movably installed on the lead screw 72 through a bearing, and then the support plate 11 is fixedly installed on the base 1. Furthermore, the support plate 11 provides stable support for the use of the lead screw 72, thereby ensuring the stability of the lead screw 72 during rotation.

[0032] Reference Figure 3 , the front surface of the front support plate 11 is fixedly connected with an installation disc 12, and the driving motor 73 is fixedly installed on the front surface of the installation disc 12.

[0033] As a technical optimization scheme of the present utility model, by providing the installation disc 12, the driving motor 73 is fixedly installed on the front support plate 11 through installation. Furthermore, the output end of the driving motor 73 can be fixedly installed on the front end of the lead screw 72 through the installation disc 12, thereby ensuring the necessary conditions for the use of the driving motor 73.

[0034] Reference Figure 3 , the front end and the rear end of the limiting rod 82 are both fixedly connected with support blocks 13, and the left side of the support block 13 is fixedly connected to the base 1.

[0035] As a technical optimization scheme of the present utility model, by providing the support block 13, the support block 13 plays a supporting role in the use of the limiting rod 82, ensuring the stability of the use of the limiting rod 82.

[0036] The working principle and usage process of the present utility model are as follows: When in use, first, the operator sets the maximum tightening pressure value that the workpiece can withstand in the controller 6. Then, the workpiece is placed in contact with the positioning plate 3 and blocks the detection end of the infrared sensor 5. At this time, the infrared sensor 5 will transmit data to the controller 6 through a wire, causing the controller 6 to start the drive motor 73. As a result, the output end of the drive motor 73 drives the lead screw 72 to rotate, and the rotating lead screw 72 drives the moving block 71 to move. Thus, the moving block 71 drives the tightening plate 2 to move towards the position of the workpiece. When the tightening plate 2 contacts and tightens the workpiece, the pressure sensor 10 will first contact the workpiece, and the pressure sensor 10 will transmit the contact signal to the inside of the controller 6 through a wire, causing the controller 6 to analyze the result. When the analysis result reaches the set maximum pressure value, the controller 6 will control the drive motor 73 to stop running, thereby avoiding the situations of the workpiece being squeezed in place and over-squeezed, and ensuring the convenience for the operator to fix the workpiece.

[0037] In summary, for this adjustable fixture for part processing, by setting the positioning plate 3, infrared sensor 5, and controller 6, when the operator needs to fix the workpiece for processing, when the operator places the workpiece in contact with the positioning plate 3 and blocks the detection end of the infrared sensor 5, the infrared sensor 5 will transmit data to the controller 6 through a wire, causing the controller 6 to start the moving mechanism 7. Thus, the moving mechanism 7 drives the tightening plate 2 to tightly fix the workpiece, thereby ensuring the convenience for the operator to fix the workpiece, and solving the problem that the above-mentioned equipment does not have a structure to assist the operator in fixing the workpiece. As a result, when the operator needs to clamp the workpiece multiple times, the operator needs to continuously manually rotate the lead screw to tightly fix the workpiece. This fixing method is overly dependent on the operator, resulting in excessive fatigue for the operator.
