Description

Technical Field

[0001] The utility model relates to a jig, in particular to a magnetization jig with high stability. Background Art

[0002] In the process of industrial production, sometimes it is necessary to perform unified magnetization treatment on relatively small workpieces. The traditional operation method is as follows: Place multiple workpieces to be magnetized in a long groove opened in a box body, then close the upper cover on the top of the box body. The operator holds the box body and the upper cover with both hands and applies a certain pressure to the upper cover to press and fix all the workpieces. In this state, let the box body approach the magnetic field and move the box body in the magnetic field, so that all the workpieces inside it are magnetized.

[0003] However, this operation method has many problems: First, due to problems such as tolerances, there are certain deviations in the actual heights of different workpieces. Therefore, it is impossible to ensure that all workpieces will be pressed by the upper cover at the same time. Moreover, by applying pressure manually to press the workpieces, the farther the workpiece is from the force application point, the worse the pressing effect is. That is to say, it is impossible to ensure that all workpieces can be pressed and positioned. The magnetization of the workpieces is in sequence. After the first workpiece is magnetized, the second workpiece adjacent to it will tend to approach the first workpiece under the action of magnetic force. If the second workpiece is not pressed, it will tilt under the action of magnetic force, thus affecting the magnetization effect.

[0004] Therefore, there is a need for a method or device that can solve the above problems now. Summary of the Invention

[0005] The utility model is to solve the above-mentioned deficiencies existing in the prior art, and proposes a magnetization jig with a simple structure, ingenious design, reasonable layout, which can stably and efficiently position and fix workpieces, so as to ensure the magnetization effect.

[0006] The technical solution of the utility model is: A magnetization jig with high stability, including a base 1, characterized in that: a lower box body 2 is arranged on the base 1, an upper cover body 3 is arranged to match the lower box body 2, an electric cylinder 4 is arranged below the lower box body 2, the working end of the electric cylinder 4 is connected to a support frame 5, and a permanent magnet 6 is arranged on the top of the support frame 5.

[0007] n positioning grooves 7 are arranged in the lower box body 2 at equal intervals along its length direction.

[0008] A card slot body 8 is provided on the bottom end surface of the upper cover body 3. n card slots 9 are provided in the card slot body 8. A top column 10 is movably connected in the card slot 9. A spring 11 is provided above the top column 10. At the same time, a rubber gasket 12 located outside the card slot 9 is also provided at the bottom end of the top column 10. The n rubber gaskets 12 correspond to the n positioning slots 7 one by one. The upper cover body 3 is fixedly connected to the lower box body 2 through a bolt 15 provided on its side wall.

[0009] A control box 13 is further provided on the base 1. The control system in the control box 13 can control the electric cylinder 4.

[0010] Compared with the prior art, the present utility model has the following advantages:

[0011] The magnetic attachment jig with high stability of this structural form has a simple structure, ingenious design and reasonable layout. It aims at the problems existing in the traditional workpiece magnetic attachment operation process and designs a special structure. It uses the positioning slots in the lower box body to limit the freedom degree of the workpiece in the horizontal direction, and then uses the top column with a spring in the upper cover body to limit the freedom degree of the workpiece in the vertical direction. That is to say, as long as the box body and the cover body are in the closed state, all the workpieces in the box body will be positioned and clamped. This structure can ensure that the workpiece will not be displaced during the magnetic attachment process, thus ensuring the magnetic attachment effect. Moreover, it can also improve the unity of magnetic attachment treatment of multiple workpieces, avoiding inconsistent magnetic attachment effects of workpieces and the need to add a step to adjust the magnetic attachment effect. And its manufacturing process is simple and the manufacturing cost is low. Therefore, it can be said that it has multiple advantages and is especially suitable for popularization and application in this field, and its market prospect is very broad.

[0014] Figure 3 is a partial cross-sectional view of an embodiment of the present utility model. Detailed Embodiment

[0015] The following will describe the detailed embodiment of the present utility model in conjunction with the drawings. As Figures 1 to 3 shown: A magnetic attachment jig with high stability includes a base 1 as a foundation. A lower box body 2 is provided on the base 1. An upper cover body 3 is provided to match the lower box body 2. An electric cylinder 4 is provided below the lower box body 2. The working end of the electric cylinder 4 is connected to a support frame 5. A permanent magnet 6 is provided at the top of the support frame 5.

[0016] There are n positioning grooves 7 arranged at equal intervals along the length direction in the lower box body 2.

[0017] On the bottom end surface of the upper cover body 3, there is a clamping groove body 8. There are n clamping grooves 9 arranged in the clamping groove body 8. A top column 10 is movably connected in the clamping groove 9. A spring 11 is arranged above the top column 10. At the same time, a rubber gasket 12 located outside the clamping groove 9 is also arranged at the bottom end of the top column 10. The n rubber gaskets 12 correspond to the n positioning grooves 7 one by one. The upper cover body 3 is fixedly connected to the lower box body 2 through bolts 15 arranged on its side wall.

[0018] A control box 13 is also arranged on the base 1. The control system in the control box 13 can control the electric cylinder 4.

[0019] The working process of the high-stability magnetization fixture in the embodiment of the present utility model is as follows: First, a plurality of workpieces 14 to be magnetized are placed one by one in the positioning grooves 7 arranged on the lower box body 2. Then, the upper cover body 3 is buckled on the lower box body 2, and all the bolts 15 are tightened. At this time, the upper cover body 3 and the lower box body 2 are combined into an integral structure. In the initial state, under the action of the spring 11, all the top columns 10 are in the lower limit position. When the upper cover body 3 is buckled on the lower box body 2, the rubber gasket 12 at the bottom end of the top column 10 will contact the upper surface of the workpiece 14, and the top column 10 moves upward, and the spring 11 is compressed. That is to say, all the workpieces 14 will be pressed by the corresponding top columns 10 in the positioning grooves 7, and the pressing force is provided by the spring 11.

[0020] Then, the operator issues an instruction to the control system through the control box 13. The control system sends a signal to the electric cylinder 4. The electric cylinder 4 drives the support frame 5 to move from one end to the other end along the length direction of the lower box body 2. During the movement, the magnetic field generated by the permanent magnet 6 arranged on the support frame 5 will magnetize the multiple workpieces 14 located in the lower box body 2. During the magnetization process, since each workpiece 14 is pressed by the rubber gasket 12 and cannot displace, it can effectively ensure that each workpiece 14 maintains a stable posture during the process of passing through the magnetic field, so as to obtain a higher magnetization effect; at the same time, it can effectively improve the uniformity of workpiece magnetization.

[0021] After the support frame 5 moves to the other end, there is no interference from any object above the upper cover body 3. At this time, the upper cover body 3 can be opened, and all the magnetized workpieces 14 can be taken out from the positioning grooves 7.
