Description

Technical Field

[0001] This application relates to the field of tooling and fixture technology, and in particular to a beveled chip positioning tool. Background Technology

[0002] Inclined blocks are commonly used in mechanical structures to provide support or guidance. As a support element, an inclined block can withstand forces from different directions, ensuring the stability and durability of the mechanical structure. As a guiding element, an inclined block utilizes the sliding or rolling properties of its inclined surface to achieve precise positioning and smooth movement between components, which is crucial for improving the operating efficiency and accuracy of mechanical equipment. Therefore, whether in heavy machinery, precision instruments, or small devices in daily life, inclined blocks have become an indispensable part of mechanical design due to their unique advantages and wide range of applications.

[0003] Currently, the processing of inclined blocks usually involves first fixing the square workpiece on a milling machine using a bench vise, then machining one side of the workpiece using the milling machine, and then changing the position of the workpiece to process the other inclined surfaces. Fixing the workpiece with a bench vise requires the operator to constantly adjust the position of the workpiece so that it tilts in the specified direction. This fixing method is cumbersome and affects processing efficiency.

[0004] Regarding the aforementioned technologies, the inventors believe that there is a drawback: low processing efficiency of inclined blocks. Utility Model Content

[0005] To improve the machining efficiency of inclined blocks, this application provides an inclined chip positioning fixture.

[0006] The inclined plane chip positioning fixture provided in this application adopts the following technical solution:

[0007] A beveled chip positioning fixture includes a base and a positioning groove formed on the base for tilting the workpiece. A limiting mechanism for abutting the workpiece is detachably provided in the positioning groove.

[0008] By adopting the above technical solution, when processing inclined blocks, the operator places the base on the operating table, places the workpiece to be processed in the positioning groove, and then uses the limiting mechanism to abut against the side wall of the workpiece and place it in the positioning groove, which makes it more convenient and faster to fix the workpiece to be processed and improves the efficiency of fixing the workpiece.

[0009] Preferably, the limiting mechanism includes a limiting member detachably disposed in the positioning groove and a locking assembly for fixing the limiting member.

[0010] By adopting the above technical solution, in practical applications, operators only need to place the workpiece to be processed into the positioning groove, then adjust the position of the limiting component to make it fit tightly against the side wall of the workpiece. Then, the locking assembly is used to fix the limiting component in the positioning groove to prevent the limiting component from loosening or shifting due to force during processing, thereby achieving the fixation of the workpiece and improving work efficiency.

[0011] Preferably, the limiting member is a limiting block with its side wall inclined, and the side inclination angle of the limiting block is the same as the angle at which the workpiece to be processed is placed.

[0012] By adopting the above technical solution, a tight fit between the limit stop and the workpiece is achieved, ensuring the stability of the workpiece during processing, avoiding processing errors caused by workpiece shaking or displacement, and improving the operation accuracy. In addition, since the tilt angle of the limit stop is consistent with the tilt angle of the workpiece, after the workpiece is milled along the limit stop, the side wall of the workpiece naturally has a corresponding tilt angle, making the workpiece more convenient and efficient in subsequent use and assembly.

[0013] Preferably, the locking assembly includes a through hole formed on the limiting block and a positioning member disposed in the through hole, and the positioning groove has a positioning hole for the positioning member to be inserted.

[0014] By adopting the above technical solution, the detachable setting of the limiting block and the positioning groove is realized. A through hole is opened on the limiting block, and a positioning hole that matches the through hole is set on the positioning groove. This ensures that the positioning component can be screwed in accurately and without error, so that the limiting block is firmly fixed in the positioning groove. In turn, the workpiece is stably clamped between the limiting block and the positioning groove, ensuring the stability of the workpiece during the processing and greatly improving the processing accuracy and efficiency. In addition, the detachable setting between the limiting block and the positioning groove facilitates timely cleaning and maintenance, and improves the utilization rate of the tooling.

[0015] Preferably, the positioning element is fitted with an elastic element at the bottom of the limiting block to facilitate changing the workpiece direction.

[0016] With the above technical solution, when it is necessary to change the direction of the workpiece, the operator only needs to loosen the screw, and the elastic potential energy stored inside the elastic element begins to be released, pushing the limit block to move away from the inner wall of the positioning groove. As the limit block moves, the contact pressure between it and the side wall of the workpiece gradually decreases until it is completely separated, thus providing the operator with enough space to adjust the direction of the workpiece, improving the flexibility of the work and the convenience of use.

[0017] Preferably, the elastic element is a spring, and the end of the spring abuts against the side of the limiting block near the positioning groove.

[0018] By adopting the above technical solution, the limiting block is fixed in the positioning groove by screws. A spring is sleeved on the outer wall of the screw. During the tightening of the screw, the spring is compressed and stores elastic potential energy. When it is necessary to change the direction of the workpiece, the screw is loosened, and the spring drives the limiting block to move along the height direction under its own rebound force, thereby separating the limiting block from the side wall of the workpiece, which facilitates changing the direction of the workpiece and improves the ease of operation of the tooling.

[0019] Preferably, the positioning groove is provided with a clearance groove to facilitate the fit between the workpiece and the positioning groove.

[0020] By adopting the above technical solution, the workpiece can be placed more smoothly in the positioning groove, avoiding errors caused by sharp corners contacting each other, increasing the contact area and fit between the bottom of the workpiece and the positioning groove, and also making the limiting mechanism fit more tightly with the side wall of the workpiece, thus fixing the workpiece, improving the operation accuracy, and reducing rework and scrap rates caused by errors.

[0021] Preferably, the base is provided with several sets of magnets, and the base is fixed to the operating table by the magnets.

[0022] By adopting the above solution, several sets of magnets are set on the base. The magnets firmly attract the base to the operating table through the magnetic field, which improves the stability of the tooling and makes it less likely to shake or shift during operation, thus ensuring the processing accuracy. At the same time, the use of magnetic attraction to fix the tooling avoids the problem of falling off due to vibration caused by using clamps or screws, thus improving the safety of the tooling.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. This application provides a positioning groove on the base for placing the workpiece, and a limiting block with the same inclination as the side wall of the workpiece can be detachably installed in the positioning groove, which makes it easier and faster to fix the workpiece to be processed and improves the processing efficiency of the inclined block.

[0025] 2. By setting a clearance groove on the positioning groove, this application achieves a tight fit between the positioning groove and the workpiece, avoiding errors caused by sharp corners contacting each other, and further improving the machining accuracy of the inclined block;

[0026] 3. This application provides sufficient space for workers to adjust the direction of the workpiece by fitting an elastic element on the outer wall of the positioning part and having the end of the elastic element abut against the limiting block. When it is necessary to change the direction of the workpiece, the operator only needs to loosen the screw, so that the elastic element's own rebound force drives the limiting block to separate from the side wall of the workpiece. This improves the flexibility and ease of use of the tooling. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a beveled chip positioning fixture.

[0034] A beveled chip positioning fixture, as shown in the reference Figure 1 and Figure 3 It includes a base 1, a positioning groove 2, a limiting mechanism 3, and a positioning hole 4. The limiting mechanism 3 includes a limiting member 31 and a locking assembly 32. The limiting member 31 is a limiting block 311. The locking assembly 32 includes a through hole 321 and a positioning member 322.

[0035] The positioning groove 2 is provided through the upper side wall of the base 1, and several sets are arranged parallel to the long side of the base 1. The limiting block 311 is provided in the positioning groove 2, and the side wall of the limiting block 311 is inclined. The through hole 321 is provided through the limiting block 311. The positioning member 322 is provided on the limiting block 311 through the through hole 321. The positioning hole 4 is adapted to the positioning member 322 and is opened on the end face of the positioning groove 2.

[0036] When machining inclined blocks, the limiting block 311 is placed in the positioning groove 2, and then the workpiece to be machined is inserted into the positioning groove 2 and tightly fitted with the limiting block 311. Then, the positioning component 322 is tightened to fix the limiting block 311, so that the side wall of the limiting block 311 abuts against the side wall of the workpiece, thereby fixing the workpiece to be machined and improving the efficiency of fixing the workpiece. In addition, since the side wall of the limiting block 311 is inclined, the side wall of the workpiece after being milled by the milling machine naturally has a corresponding inclined angle, making the workpiece more convenient and efficient in subsequent use and assembly. Multiple sets of parallel positioning grooves 2 enable the machining of multiple workpieces at once, thereby improving the machining efficiency of metal blocks.

[0037] To further improve machining accuracy, refer to Figure 4 The positioning groove 2 is provided with a clearance groove 6 relative to the two ends of the workpiece. When performing inclined block processing, the workpiece is placed on the positioning groove 2 so that its bottom surface is in close contact with the upper surface of the positioning groove 2. By providing the clearance groove 6, the error caused by sharp corner to sharp corner contact is avoided, which significantly improves the fit between the workpiece and the positioning groove 2 and the limiting block 311, improves the operation accuracy, and reduces the rework and scrap rate caused by errors.

[0038] To further improve the ease of use of tooling, refer to Figure 2 and Figure 3 The outer wall of the positioning member 322 is fitted with an elastic member 5, which is a spring 51. The top end of the spring 51 abuts against the side of the limiting block 311 near the positioning groove 2.

[0039] When machining inclined blocks, the workpiece is placed in the positioning groove 2, and the side wall of the limiting block 311 abuts against the side wall of the workpiece. Then, the positioning component 322 is tightened, so that the spring 51 is compressed and stores elastic potential energy. When it is necessary to change the direction of the workpiece, the positioning component 322 is loosened, so that the spring 51 drives the limiting block 311 to separate from the side wall of the workpiece under its own rebound force, thereby providing the operator with enough space to change the direction of the workpiece and improving the ease of operation of the tooling.

[0040] To further improve the stability of the tooling, refer to Figure 2 The base 1 has several sets of magnets 7 on the side near the operating table. When the base 1 is placed on the operating table, the magnets 7 firmly attract the base 1 to the operating table through the magnetic field, which prevents the tooling from shaking or shifting during operation and improves the stability of the tooling.

[0041] The working process and implementation principle of the inclined chip positioning fixture in Example 1 are as follows: This application achieves the fixation of the workpiece by opening a positioning groove 2 on the side wall of the base 1 and setting a limiting mechanism 3 in the positioning groove 2; by opening an avoidance groove 6 on the positioning groove 2, the machining accuracy of the inclined block is improved; the fixture also has stability, by setting a magnet 7, the base 1 is firmly attached to the operating table, avoiding the fixture from being unstable and shifting during the working process.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
