Description

Technical Field

[0001] The utility model relates to the technical field of fixtures, in particular to a longitudinal positioning device for manufacturing precision fixtures. Background Art

[0002] In the process of manufacturing precision fixtures, it is necessary to reliably fix the precision fixtures. Among them, the longitudinal positioning device for precision fixtures is a device used to position the precision fixtures to be processed, and it has been widely used in the field of precision fixture processing.

[0003] The current positioning device generally fixes the precision fixture through a pneumatic chuck. In order to facilitate the adjustment of the clamping position of the precision fixture, the positioning device is generally set to be movable, that is, it can adjust the longitudinal position of the precision fixture. However, when generally adjusting to a specified position, the precision fixture is directly fixed by the positioning device, lacking a locking mechanism for the positioning device. Therefore, during the manufacturing and processing of precision fixtures, the positioning device is likely to move, affecting the manufacturing of precision fixtures. Summary of the Utility Model

[0007] The positioning component includes a groove opened at the bottom of the moving block, a fixing plate is fixedly installed in the groove, a positioning pin is slidably penetrated through the top of the fixing plate, a magnetic block is fixedly installed at the upper end of the positioning pin, two springs are commonly connected between the magnetic block and the fixing plate, and an electromagnet is fixedly installed at the top of the groove. When the electromagnet is energized, it repels the magnetic block;

[0008] A plurality of positioning grooves are opened at the inner bottom of the fixed track, and the positioning grooves are arranged in a linear array and are engaged with or separated from the positioning pins.

[0009] Preferably, four ear plates are symmetrically and fixedly installed on the outer wall of the fixed track, and mounting holes are opened on the surface of each ear plate.

[0013] Preferably, the pneumatic chuck is electrically connected to the electromagnet.

[0014] Compared with the existing technology, the advantages of the longitudinal positioning device for precision fixture manufacturing provided by the present utility model are as follows:

[0015] After the pneumatic chuck is moved to the designated position in the present utility model, when the pneumatic chuck is controlled to clamp the precision fixture, the electromagnet is energized, and then it starts to repel the magnetic block to push the magnetic block to move in a direction away from it until the positioning pin is driven to move downward and inserted into the corresponding positioning groove, so that the position of the moving block can be fixed, thereby realizing the locking of the pneumatic chuck to ensure the precise positioning of the precision fixture in the longitudinal position and achieving the effect of automatically locking the longitudinal positioning device.

Detailed Embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Refer to Figures 1 to 4, A longitudinal positioning device for precision fixture manufacturing, including a fixed track 1. Four ear plates 11 are symmetrically and fixedly installed on the outer wall of the fixed track 1. Each ear plate 11 is provided with a mounting hole 12 on its surface. During use, screws or rivets can be used to pass through the mounting holes 12 on each corresponding ear plate 11 in turn, and then the fixed track 1 can be installed at a specified position.

[0023] A pneumatic chuck 2 is slidably connected to the top of the fixed track 1. The pneumatic chuck 2 is a clamping device in the prior art and will not be elaborated in detail in this technical solution. During use, the precision fixture to be processed can be placed on the pneumatic chuck 2, and it can be clamped and fixed by controlling the pneumatic chuck 2.

[0024] Two second moving wheels 15 that are symmetrically installed at the bottom of the pneumatic chuck 2 and roll on the top of the fixed track 1 play a supporting role for the pneumatic chuck 2, and can prevent contact between the pneumatic chuck 2 and the fixed track 1 from increasing the frictional resistance during its sliding.

[0025] A moving block 3 that is fixedly installed at the bottom of the pneumatic chuck 2 and slidably arranged in the fixed track 1. First moving wheels 13 are installed on both side walls of the moving block 3, and guide grooves 14 are opened on both inner walls of the moving block 3. The two first moving wheels 13 are respectively arranged to roll in the two guide grooves 14. Under the sliding limit between the two first moving wheels 13 and the corresponding guide grooves 14, it can prevent the pneumatic chuck 2 from detaching from the fixed track 1 during the moving process. At the same time, through the rolling of each first moving wheel 13 in the corresponding guide groove 14, the frictional resistance of the moving block 3 moving in the fixed track 1 can be reduced, and the moving flexibility of the moving block 3 and the pneumatic chuck 2 is improved.

[0026] A positioning component is arranged between the moving block 3 and the fixed track 1; the positioning component includes a groove 4 opened at the bottom of the moving block 3. A fixing plate 5 is fixedly installed in the groove 4. A positioning pin 6 is slidably penetrated through the top of the fixing plate 5. A magnetic block 8 is fixedly installed at the upper end of the positioning pin 6. The outer surface of the magnetic block 8 is slidably attached to the surface of the groove 4, ensuring the stability of the magnetic block 8 during the up and down movement.

[0027] There are two springs 9 connected between the magnetic block 8 and the fixing plate 5. An electromagnet 10 is fixedly installed at the top of the groove 4. When the electromagnet 10 is energized, it repels the magnetic block 8. A plurality of positioning grooves 7 are formed at the inner bottom of the fixed track 1, and the positioning grooves 7 are arranged in a linear array and are engaged or separated from the positioning pins 6. When it is necessary to move the longitudinal position of the pneumatic chuck 2, the pneumatic chuck 2 is pushed to slide on the fixed track 1. After it moves to the designated position, the external power supply of the device is connected, and the electromagnet 10 will be energized. Then it starts to repel the magnetic block 8 and pushes the magnetic block 8 to move away from it until the positioning pin 6 is driven to move downward and inserted into the corresponding positioning groove 7, so that the position of the moving block 3 can be fixed, thereby realizing the locking of the pneumatic chuck 2, ensuring the precise positioning of the precision fixture in the longitudinal position, and achieving the effect of automatically locking the longitudinal positioning device.

[0028] Furthermore, the pneumatic chuck 2 is electrically connected to the electromagnet 10. When the pneumatic chuck 2 is energized, the electromagnet 10 will be energized synchronously, which has a certain degree of automation effect.

[0029] The working principle of the present utility model is as follows:

[0030] During use, when it is necessary to move the longitudinal position of the pneumatic chuck 2, the pneumatic chuck 2 is pushed to slide on the fixed track 1. After it moves to the designated position, the precision fixture to be manufactured is placed on the pneumatic chuck 2, and it can be clamped and fixed by controlling the pneumatic chuck 2;

[0031] At this time, the electromagnet 10 will also be energized. Then it starts to repel the magnetic block 8 and pushes the magnetic block 8 to move away from it until the positioning pin 6 is driven to move downward and inserted into the corresponding positioning groove 7, so that the position of the moving block 3 can be fixed, thereby realizing the locking of the pneumatic chuck 2 to ensure the precise positioning of the precision fixture in the longitudinal position and achieving the effect of automatically locking the longitudinal positioning device.

[0032] Further explanation, the above fixed connection, unless otherwise clearly specified and limited, should be understood in a broad sense. For example, it can be welding, gluing, or integrally formed setting, etc., which are common means well-known to those skilled in the art.

[0033] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
