Description

Technical Field

[0001] The present application relates to the technical field of positioning jigs, and in particular to a positioning jig. Background Art

[0002] Based on different processing workpieces and processes, different positioning fixtures need to be replaced to fix the workpieces, such as hydraulic dies, punches, concave dies, shear dies, etc.; and when the spark machine is sparking, it is necessary to use measuring tools (such as micrometers, vernier calipers, etc.) for each copper rod and workpiece to measure and confirm the size, position and other parameters of the workpiece. After that, the workpiece needs to be adjusted vertically and divided. Every time a different workpiece is replaced for processing, it is necessary to re-measure, debug and install, which is time-consuming and has low processing efficiency.

[0003] Therefore, based on the above problems, the prior art needs to be improved. Utility Model Content

[0004] The purpose of this application is to facilitate the installation and positioning of workpieces and improve the processing efficiency of workpieces.

[0005] The above technical purpose of the present application is achieved through the following technical solutions: a positioning fixture, including a base, a mounting groove is provided on the base, a positioning column is provided on the side of the base away from the mounting groove, a first slot is recessed on the base, a first pin is detachably installed in the first slot, and there are multiple first slots.

[0006] By adopting the above technical solution, the base is fixed on the machine tool through the mounting groove, and the object to be positioned is inserted through the positioning column and the first pin is installed on the base, which can achieve accurate positioning of the object to be positioned, ensure the accurate position of the object to be positioned during processing or other operations, and reduce the possibility of movement during processing. The first pin can be disassembled, and the jig can be adjusted and reconfigured according to different needs and workpieces, increasing its flexibility and versatility. The positioning column provides additional support, which can enhance the stability of the object to be positioned on the jig and reduce errors caused by movement or vibration. The jig has precise positioning, detachability, and enhanced stability, which helps to improve production efficiency and reduce the time and labor costs of operators.

[0007] Optionally, a second slot is recessed on the base, a second latch is detachably installed in the second slot, the second slot is arranged on a side of the positioning column away from the first slot, and the second slot is arranged corresponding to the first slot.

[0008] By adopting the above technical solution, by setting up a slot and a corresponding pin on the positioning column and the base, the jig provides multiple positioning supports, so that the object to be positioned can be fixed on the jig more stably. The second slot is set to correspond to the first slot, so that the positioning of the second pin is associated with the first pin, further improving the accuracy and stability of positioning. Through the detachability of the second slot and the second pin, the jig has greater applicability and can be adjusted and configured according to different workpiece shapes and sizes, increasing its flexibility and versatility.

[0009] Optionally, the first latch and the second latch have the same structure, and the first latch comprises an inserting portion and a limiting portion, and the inserting portion is connected to the limiting portion.

[0010] By adopting the above technical solution, since the first latch and the second latch have the same structure, including the same plug-in portion and limit portion, this means that they are consistent in manufacturing and use, and can achieve standardized production and operation processes, simplifying the production and maintenance process. The presence of the plug-in portion ensures that the latch is firmly fixed in the slot, avoids inaccurate positioning or accidental damage to the workpiece due to loosening or falling off, and improves the safety and stability of the fixture.

[0011] Optionally, the plug-in portion is provided with an external thread, and the inner walls of the first slot and the second slot are provided with an internal thread, and the plug-in portion is plugged into the first slot or the second slot through the cooperation of the external thread and the internal thread.

[0012] By adopting the above technical solution, the plug-in part can form a firm connection with the slot through the cooperation of the external thread and the internal thread. Threaded connections usually have good tensile strength and vibration resistance, so they can effectively prevent problems such as inaccurate positioning or workpiece falling off caused by loosening of the pin during use. Threaded connections allow the pin to be fine-tuned in the slot to ensure the best positioning effect. By rotating the pin, its depth can be adjusted so that the workpiece can reach the desired position and angle, thereby improving the accuracy of positioning. Due to the use of threaded connections, the pin can be relatively easy to disassemble and replace. This is particularly useful for production lines that require frequent replacement of workpieces or maintenance, which can save a lot of time and labor costs. Threaded connections usually have high wear resistance and corrosion resistance, so they can increase the service life of the pin and slot and reduce the frequency of repairs and replacements due to damage to the connecting parts.

[0013] Optionally, a guide surface is provided at one end of the limiting portion away from the plug-in portion.

[0014] By adopting the above technical solution, the guide surface can help the operator to more easily correctly and accurately install the object to be positioned on the base through the first latch or the second latch, reducing the complexity and time consumption during the operation. It helps to improve the operating efficiency and reduce the possibility of the first latch or the second latch and the object to be positioned being damaged during installation.

[0015] Optionally, the base is provided with ridges.

[0016] By adopting the above technical solution, the presence of the ridges can increase the friction between the base and the operator, thereby reducing the risk of the base slipping during installation or transfer; the addition of the ridges can increase the structural strength and stability of the base, thereby better bearing the weight of the workpiece and external pressure. It helps to extend the service life of the base and reduce the frequency of maintenance and replacement.

[0017] In summary, this application has at least the following beneficial effects:

[0018] 1. The base is fixed on the machine tool through the mounting groove, and the object to be positioned is inserted through the positioning column and the first pin is installed on the base, which can achieve accurate positioning of the object to be positioned, ensure the accurate position of the object to be positioned during processing or other operations, and reduce the possibility of movement during processing. The first pin can be disassembled, and the fixture can be adjusted and reconfigured according to different needs and workpieces, increasing its flexibility and versatility. The positioning column provides additional support, which can enhance the stability of the object to be positioned on the fixture and reduce errors caused by movement or vibration. The fixture has precise positioning, detachability, and enhanced stability, which helps to improve production efficiency and reduce operator time and labor costs.

[0019] 2. Through the cooperation of external and internal threads, the plug-in part can form a firm connection with the slot. Threaded connections usually have good tensile and vibration resistance, so they can effectively prevent problems such as inaccurate positioning or workpiece falling off caused by loosening of the pin during use. Threaded connections allow the pin to be fine-tuned in the slot to ensure the best positioning effect. By rotating the pin, its depth can be adjusted so that the workpiece can reach the desired position and angle, improving the accuracy of positioning. Due to the threaded connection, the pin can be removed and replaced relatively easily. This is particularly useful for production lines that require frequent replacement of workpieces or maintenance, which can save a lot of time and labor costs. Threaded connections usually have high wear resistance and corrosion resistance, so they can increase the service life of the pin and slot and reduce the frequency of repairs and replacements due to damage to the connecting parts.

[0020] 3. The presence of ridges can increase the friction between the base and the operator, thereby reducing the risk of the base slipping during installation or transfer; the addition of ridges can increase the structural strength and stability of the base, thereby better bearing the weight of the workpiece and external pressure. It helps to extend the service life of the base and reduce the frequency of maintenance and replacement. BRIEF DESCRIPTION OF THE DRAWINGS

A first latch 5 is detachably installed in the first slot 4.

[0029] When the operator installs the first latch 5 in the first slot 4 according to the position of the mounting groove on the workpiece to be processed, the operator aligns the mounting groove on the workpiece with the positioning column 3 and the first latch 5, and then installs the workpiece on the base 1. The mounting groove of the workpiece avoids the positioning column 3 and the first latch 5 is installed on the base 1, so that the workpiece is stably set on the base 1 and waits for processing. After the processing of the current workpiece is completed, the first latch 5 is replaced and inserted into the first slot 4 at a different position, so that different workpieces can be accurately and stably installed on the base 1.

[0030] In this embodiment, refer to Figure 1 A second slot 6 is recessed on the base 1, and a second latch 7 is detachably installed in the second slot 6. The second slot 6 is arranged on a side of the positioning column 3 away from the first slot 4. The second slot 6 is arranged corresponding to the first slot 4. Preferably, the positions of the first slot 4 and the second slot 6 are axially symmetrical about the position of the positioning column 3. When the workpiece is mounted on the base 1, the first latch 5 and the second latch 7 are simultaneously limited by the aligned positions, so that the workpiece can be evenly stressed, thereby improving the stability and accuracy of the workpiece installed on the base 1.

[0031] In this embodiment, refer to Figure 3-4 The first latch 5 and the second latch 7 have the same structure. The first latch 5 and the second latch 7 both include an inserting portion 51 and a limiting portion 52. The inserting portion 51 is inserted into the first slot 4 or the second slot 6. The limiting portion 52 is inserted into the mounting groove of the workpiece to limit the workpiece so that the workpiece is stably installed on the base 1. In another embodiment, referring to Figure 4 The plug-in portion 51 of the first plug pin 5 and the second plug pin 7 is provided with an external thread, and the inner wall of the first slot 4 and the second slot 6 is provided with an internal thread. The plug-in portion 51 is inserted into the first slot 4 or the second slot 6 through the cooperation of the external thread and the internal thread. The length of the first plug pin 5 or the second plug pin 7 exceeding the base 1 can also be adjusted through the external thread and the internal thread, so as to cooperate with workpieces with different stable thicknesses.

[0032] In this embodiment, refer to Figure 3-4 A guide surface 8 is provided at one end of the limiting portion 52 away from the plug-in portion 51, that is, an arc spherical surface is provided at one end of the limiting portion 52 away from the plug-in portion 51. When the workpiece is installed, the risk of damage to the workpiece caused by the corners of the limiting portion 52 is reduced, and at the same time, it is convenient for the operator to install the workpiece quickly and accurately.

[0033] In this embodiment, refer to Figure 1 The base 1 is preferably a rectangular parallelepiped, and ridges 9 are provided on the four sides of the base 1. The ridges 9 can increase the friction between the base 1 and the operator, thereby reducing the risk of the base 1 slipping during installation or transfer; the addition of the ridges 9 can increase the structural strength and stability of the base 1, thereby better bearing the weight of the workpiece and external pressure. This helps to extend the service life of the base 1 and reduce the frequency of maintenance and replacement.

[0034] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
