Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal tool processing technology, and in particular to an adaptive fixture for grinding non-standard metal tools. Background Technology
[0002] Test fixtures are specialized tools used to test and experiment with a product's functionality, power calibration, lifespan, performance, and other aspects. Many fixtures are created out of commercial necessity, as many types are customized to improve productivity, repeat specific actions, or make work more precise. Non-standard fixtures are special tools and equipment used in the manufacturing industry to assist in the production process. They are usually not suitable for general production lines or processing processes. They need to be designed and manufactured in a personalized manner according to specific production processes, product shapes, sizes and other factors. They are highly customizable and can be designed for the special structures and process requirements of different products to meet the needs of precise positioning, clamping, inspection and other requirements. However, non-standard fixtures require the use of clamps during the production process. But for fixtures with shapes that are different from the conventional ones, traditional clamps cannot hold them when using them, which causes the fixtures to shift and be damaged during subsequent processing. Utility Model Content
[0003] The purpose of this invention is to address the aforementioned problems and shortcomings by proposing an adaptive fixture for grinding non-standard metallurgical tools.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: An adaptive fixture for grinding non-standard metal tools includes a worktable. A positioning hole is provided at the center of the top outer wall of the worktable, and a bidirectional screw is rotatably connected to the center of the positioning hole. Both ends of the bidirectional screw are threadedly connected to the outer walls of the two ends of the worktable. A positioning block is installed on the top outer wall of the mounting block. Fixing components are provided on both sides of the outer wall of the worktable at equal intervals, and pressing components are provided at the four corners of the worktable. The fixing components include fixing holes provided on the side outer walls of the worktable, fixing screws rotatably connected to the center of the fixing holes, mounting blocks II threadedly connected to the outer walls of the fixing screws, and fixing blocks installed on the top outer walls of the mounting blocks II.
[0005] Preferably, the outer wall of one side of the fixing block is provided with equally spaced sliding grooves, and the inner wall of the sliding groove is slidably connected to a pop-out rod, one end of which is provided with a soft pad.
[0006] Preferably, a knob is welded to the outer wall of one end of the fixing screw, and the mounting block two is slidably connected to the inner wall of the fixing hole. A support spring is welded to one end of the pop-out rod, and the other end of the support spring is installed on the inner wall of one end of the sliding groove.
[0007] Preferably, a motor is installed on one end of the outer wall of one side of the workbench, and the output shaft of the motor is connected to one end of a bidirectional screw. The outer wall of the mounting block is slidably connected to the inner wall of the positioning hole, and a contact pad is sleeved on the outer wall of the positioning block.
[0008] Preferably, the pressing assembly includes mounting holes at the four corners of the workbench, an electric push rod installed on the inner wall of the mounting hole, and a pressing rod rotatably connected to the outer wall of the top of the electric push rod, and a rubber pad is adhered to the bottom outer wall of the pressing rod.
[0009] Preferably, the electric push rod and the motor are connected to a switch via wires, and the switch is connected to a power source via wires.
[0010] The beneficial effects of this utility model are as follows: After the ejector rod contacts the fixture, the fixing screw continues to rotate, causing the fixture to compress the ejector rod and the support spring. This causes a part of the fixture to be embedded in the ejector rod of the fixing block, which facilitates fixing and allows for deformation according to the shape of the contact surface, thereby improving the fixing stability. The retraction of the electric push rod drives the pressing rod to descend, which in turn acts on the fixture, confining the fixture to the worktable. This facilitates fixture control, aids in machining, and improves stability. Attached Figure Description

Detailed Implementation
[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example
[0014] Reference Figure 1-3As shown, an adaptive fixture for grinding non-standard metal tools includes a worktable 1. The worktable 1 has a positioning hole 2 at the center of its top outer wall, and a bidirectional screw 3 is rotatably connected to the center of the positioning hole 2. The outer walls of both ends of the bidirectional screw 3 are threaded with mounting blocks 4, and the top outer wall of the mounting blocks 4 is fitted with positioning blocks 5. The outer walls of both sides of the worktable 1 are provided with fixing components 8 distributed at equal intervals, and the four corners of the worktable 1 are provided with pressing components 9. A motor 7 is installed on one end of the outer wall of one side of the workbench 1, and the output shaft of the motor 7 is connected to one end of the bidirectional screw 3. The outer wall of the mounting block 4 is slidably connected to the inner wall of the positioning hole 2, and the outer wall of the positioning block 5 is fitted with a contact pad 6. The pressing assembly 9 includes mounting holes 10 at the four corners of the workbench 1, an electric push rod 11 installed on the inner wall of the mounting hole 10, and a pressing rod 12 rotatably connected to the outer wall of the top of the electric push rod 11, and a rubber pad is glued to the bottom outer wall of the pressing rod 12. The electric push rod 11 and the motor 7 are connected to a switch via wires, and the switch is connected to a power source via wires. The retraction of the electric push rod 11 drives the pressing rod 12 to descend and act on the fixture, thus restricting the fixture on the worktable 1. This facilitates the restriction of the fixture, aids in processing, and improves the stability of the fixture. The motor 7 starts and drives the bidirectional screw 3 to rotate. After the bidirectional screw 3 rotates, it drives the positioning blocks 5 to move closer to each other through the mounting block 4. The positioning blocks 5 move closer to each other and cooperate with the contact pad 6 to fix the fixture at the center of the worktable 1. Example
[0015] Reference Figure 1-3 As shown, the fixing component 8 includes a fixing hole 13 opened on the outer wall of the side of the workbench 1, a fixing screw 14 rotatably connected to the center of the fixing hole 13, a mounting block 15 threadedly connected to the outer wall of the fixing screw 14, and a fixing block 17 installed on the top outer wall of the mounting block 15. The outer wall of one side of the fixed block 17 is provided with sliding grooves 18 that are evenly distributed, and the inner wall of the sliding groove 18 is slidably connected to a pop-out rod 20, and one end of the pop-out rod 20 is provided with a soft pad. A knob 16 is welded to the outer wall of one end of the fixing screw 14, and the mounting block 2 15 is slidably connected to the inner wall of the fixing hole 13. A support spring 19 is welded to one end of the pop-out rod 20, and the other end of the support spring 19 is installed on the inner wall of one end of the sliding groove 18. The ejector rod 20 contacts the fixture and continues to rotate the fixing screw 14, causing part of the fixture to compress the ejector rod 20 and the support spring 19, so that part of the fixture is trapped in the ejector rod 20 of the fixing block 17, which facilitates fixation and allows for deformation according to the shape of the contact surface, thereby improving the fixation stability.
[0016] Working principle: During use, the worktable 1 is fixed in the desired position using screws, etc. The fixture to be processed is placed on the top outer wall of the worktable 1. The motor 7 starts and drives the bidirectional screw 3 to rotate. After the bidirectional screw 3 rotates, it drives the positioning blocks 5 to move closer together through the mounting block 1 4. The positioning blocks 5 move closer together and, in conjunction with the contact pad 6, fix the fixture at the center of the worktable 1. According to the shape and size of the fixture, the fixing block 17 is installed on the mounting block 2 15 at the corresponding position. The fixing screw 14 is rotated by the knob 16. After the fixing screw 14 rotates, it drives the ejector rod 20 on the fixing block 17 to move closer to the fixture through the mounting block 2 15. The ejector rod 20 contacts the fixture and continues to rotate the fixing screw 14, causing part of the fixture to compress the ejector rod 20 and the support spring 19, so that part of the fixture is trapped in the ejector rod 20 of the fixing block 17, thereby completely fixing the fixture on the worktable 1, which is convenient for fixing and for deformation according to the shape of the contact surface, thus improving the fixing stability; the pressing rod 12 on the electric push rod 11 is rotated so that the pressing rod 12 is located on the fixture, and the electric push rod 11 retracts and drives the pressing rod 12 to descend and act on the fixture, restricting the fixture on the worktable 1, which is convenient for restricting the fixture, facilitating auxiliary processing, and improving the fixing stability.
