Clamp for magnetic material spraying operation

Abstract

The utility model relates to the technical field of clamps, in particular to a clamp for magnetic material spraying operation. In the spraying operation of the magnetic material, the gravity of the magnetic material acts on the gravity sensing device on the upper end face of the sensing plate. When the gravity sensing device detects the pressure change, an electric signal is sent to the driving mechanism; and after receiving the signal, the driving mechanism controls the scraping plate to start to move from the front sides of the two clamping plates and stably move to the rear sides of the two clamping plates in the direction perpendicular to the clamping plates. In the process, the scraping plate can scrape off magnetic scraps possibly adsorbed on the surface of the magnetic material and the induction plate, and the scraps are prevented from influencing the performance and the spraying effect of the magnetic material in the subsequent spraying process. According to the arrangement, magnetic scraps on the surface of the magnetic material and the induction plate can be cleaned in time after the magnetic material is placed, so that the spraying quality of the magnetic material is effectively improved, and the defective rate is reduced. The clamp can be widely applied to the technical field of clamps.

Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of clamp, more particularly to a clamp for magnetic material spraying operation. BACKGROUND

[0002] In the early processing of magnetic materials, a large amount of magnetic debris will inevitably be produced. These debris are easily adsorbed to the surface of the magnetic material. When the magnetic material is sprayed, these debris will seriously affect the performance of the magnetic material and its spraying effect.

[0003] At present, the existing magnetic material spraying operation clamp mainly focuses on the stable clamping of the magnetic material to ensure the position of the material fixed during spraying. However, there is a lack of effective measures to deal with the problem of magnetic material surface easily contaminated by debris. This leads to a high rate of defective products in actual production due to magnetic debris pollution, increasing production costs and reducing production efficiency. Therefore, it is of great practical significance to develop a clamp that can effectively handle magnetic debris during clamping to improve the quality of magnetic material spraying and improve production efficiency. SUMMARY

[0004] In view of the problems existing in the prior art, the utility model provides a clamp for magnetic material spraying operation.

[0005] In order to solve the above technical problems, the utility model solves them through the following technical schemes:

[0006] A clamp for magnetic material spraying operation, comprising a workbench and two clamping plates, an induction plate is arranged on the side wall of the clamping plate, the magnetic material is overlapped on the induction plate, a gravity sensing device is arranged on the upper end surface of the induction plate; A scraper and a driving mechanism are arranged on the workbench, the gravity sensing device is electrically connected with the driving mechanism, the scraper is arranged between the two clamping plates and perpendicular to the two clamping plates, when the gravity sensing device is pressed, the driving mechanism controls the scraper to move from the front side of the two clamping plates to the rear side of the two clamping plates, when the gravity sensing device is not pressed, the driving mechanism controls the scraper to reset to the front side of the two clamping plates.

[0007] In the magnetic material spraying operation, the two ends of the magnetic material are placed on the induction plate of the clamp, and the two clamping plates realize clamping of the magnetic material. The gravity of the magnetic material acts on the gravity sensing device of the upper end surface of the induction plate. When the gravity sensing device detects a change in pressure, it sends an electrical signal to the drive mechanism; after receiving the signal, the drive mechanism controls the scraper to move from the front side of the two clamping plates to the rear side of the two clamping plates in a direction perpendicular to the clamping plates. In this process, the scraper can scrape off the magnetic debris that may be adsorbed on the surface of the magnetic material and the induction plate, so as to avoid the influence of these debris on the performance of the magnetic material and the spraying effect in the subsequent spraying process. When the magnetic material is removed from the induction plate and the gravity sensing device is no longer under pressure, it will send another electrical signal to the drive mechanism. The drive mechanism controls the scraper to reset according to the signal, so that it returns to the front side of the two clamping plates, and prepares for the placement of the next magnetic material and the cleaning of the debris.

[0008] The above arrangement can clean the magnetic debris on the surface of the magnetic material and the induction plate in time after the magnetic material is placed through the linkage design of the gravity sensing device and the scraper, significantly reducing the performance degradation and spraying defects of the magnetic material caused by debris pollution, such as uneven coating, reduced adhesion, etc., thereby effectively improving the spraying quality of the magnetic material and reducing the rate of defective products.

[0009] As a preferred embodiment, the gravity sensing device comprises an induction groove arranged on the upper end surface of the induction plate, and a micro switch is arranged in the induction groove. The trigger button of the micro switch extends to the opening of the induction groove.

[0010] When the magnetic material is placed on the induction plate, its gravity will be transmitted to the trigger button of the micro switch at the opening of the induction groove. As the magnetic material is placed, the pressure gradually increases, and when the pressure reaches the trigger threshold of the micro switch, the micro switch is closed, generating an electrical signal and transmitting it to the drive mechanism, which immediately controls the scraper to move from the front side of the two clamping plates to the rear side of the two clamping plates to clean the magnetic debris. At the same time, the micro switch is arranged in the induction groove, reducing the interference of external environmental factors on the micro switch,

[0011] As a preferred embodiment, the upper end surface of the workbench is provided with two mounting plates perpendicular to the surface of the workbench, and a telescopic rod is fixed on the mounting plate. The other end of the telescopic rod is fixed with a clamping plate.

[0012] The telescopic rod fixed on the mounting plate can be flexibly adjusted according to the size of the magnetic material. When facing magnetic materials of different widths or thicknesses, the distance between the two clamping plates can be accurately adjusted by controlling the extension and retraction of the telescopic rod, so as to firmly clamp the magnetic material.

[0013] As a preferred embodiment, the drive mechanism comprises a suspension, the lower end surface of the suspension is provided with a guide rail, the guide rail is provided with an electric sliding block, the lower end surface of the electric sliding block is fixed with a connecting rod, and the scraper is fixed on the lower end surface of the connecting rod.

[0014] The suspension is positioned above the workbench, providing a stable support structure for the movement of the scraper. The guide rail on the lower end of the suspension defines the movement path of the electric slider, allowing it to move back and forth between the two clamping plates only along the direction of the guide rail.

[0015] Preferably, it also includes bolts, with threaded holes on the side wall of the sensing plate and elongated holes in the vertical direction on the side wall of the clamping plate, so that the bolts can pass through the elongated holes and be screwed into the threaded holes.

[0016] During the movement, the operator can adjust the induction plate to a suitable height according to the thickness of the magnetic material, ensuring that the surface of the magnetic material is slightly higher than the upper surface of the clamping plate after it is placed on the induction plate. This height setting creates favorable conditions for the scraper's cleaning operation, allowing the scraper to clean the surface of the magnetic material without obstruction. After the height is adjusted, the operator tightens the bolts again to firmly fix the induction plate to the clamping plate, ensuring that the induction plate will not shift due to external forces during the entire spraying operation, thereby maintaining the stability of the magnetic material's position and the normal operation of the gravity sensing device. The height is adjusted by the engagement of the bolts with the oblong holes and threaded holes, making the operation simple and intuitive.

[0017] Preferably, there are two threaded holes, which are respectively located at the two edges of the side wall of the induction plate.

[0018] Two threaded holes are located on the two edges of the side wall of the sensor plate, forming a stable two-point support structure. This structure can effectively prevent the sensor plate from tilting when adjusting its height.

[0019] Preferably, the sidewall of the clamping plate has graduations near the elongated hole.

[0020] When adjusting one of the sensor plates, the operator uses the corresponding scale as a reference, loosens the bolts, and then moves the sensor plate up or down to the appropriate height according to the scale. Then, when adjusting the other sensor plate, the operator compares the same scale value to ensure that both sensor plates are at the same height. This ensures that when the magnetic material is placed on the two sensor plates, it is in a horizontal position, laying the foundation for the subsequent even scraping of magnetic debris by the scraper and a high-quality spraying operation.

It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0028] Example

[0029] like Figures 1-4 As shown, the fixture used for magnetic material spraying in this embodiment mainly consists of a worktable 110, two clamping plates 120, a sensing plate 130, a gravity sensing device, a scraper 140, and a driving mechanism. Two mounting plates 150 are vertically mounted on the upper surface of the worktable 110. A telescopic rod 1501 is fixed to the mounting plate 150, and the clamping plate 120 is fixed to the other end of the telescopic rod 1501. The clamping plate 120 has a sensing plate 130 on its side wall, which is connected to the clamping plate 120 by bolts 170. A threaded hole 1303 is provided at each of the two edges of the side wall of the sensing plate 130. A vertically oriented elongated hole 1201 is correspondingly provided on the side wall of the clamping plate 120. The bolt 170 passes through the elongated hole 1201 and is screwed into the threaded hole 1303. A scale is provided on the side wall of the clamping plate 120 near the elongated hole 1201.

[0030] Adjust the height of the induction plate 130 according to the thickness of the magnetic material to be sprayed, so that the upper end face of the magnetic material is in contact with the lower end face of the scraper 140, wherein the height of the upper end face of the mounting plate 150 is lower than the height of the lower end face of the scraper 140.

[0031] The upper end face of the induction plate 130 is provided with a gravity sensing device, which is composed of an induction groove 1301 and a micro switch 1302 in the groove. The trigger button of the micro switch 1302 extends to the opening of the induction groove 1301. The workbench 110 is provided with a scraper 140 and a driving mechanism. The driving mechanism includes a suspension 160 located above the workbench 110. The lower end face of the suspension 160 is provided with a guide rail 1601. The guide rail 1601 is provided with an electric sliding block 1602. The lower end face of the electric sliding block 1602 is fixed with the scraper 140 through a connecting rod 1603. The scraper 140 is located between the two clamping plates 120 and perpendicular to the clamping plates 120.

[0032] The specific use process and principle are as follows:

[0033] The operator can adjust the height of the induction plate 130 according to the thickness of the magnetic material by loosening the bolt 170 and adjusting the scale of the clamping plate 120. After the magnetic material is placed on the induction plate 130, the upper end face is higher than the upper end face of the clamping plate 120. After adjustment, the bolt 170 is tightened to fix it. When adjusting the other induction plate 130, refer to the same scale to ensure that the two induction plates 130 are at the same height, and ensure that the magnetic material is placed horizontally.

[0034] Then place the two ends of the magnetic material on the induction plate 130. The two clamping plates 120 adjust the distance through the telescopic rod 1501 to clamp the magnetic material. The gravity of the magnetic material causes the trigger button of the micro switch 1302 on the induction plate 130 to be pressed. When the pressure reaches the trigger threshold of the micro switch 1302, the micro switch 1302 is closed and sends an electrical signal to the driving mechanism. The electric sliding block 1602 in the driving mechanism is driven by the guide rail 1601 on the lower end face of the suspension 160, and the connecting rod 1603 and the scraper 140 are moved from the front side to the rear side of the two clamping plates 120, and the surface of the magnetic material and the magnetic debris on the induction plate 130 are scraped off. When the magnetic material is removed, the micro switch 1302 is not pressed, and another electrical signal is sent. The driving mechanism controls the scraper 140 to reset to the front side of the two clamping plates 120.

[0035] Advantages

[0036] The above setting uses the gravity sensing device and the scraper 140 linkage to clean the magnetic debris in time, reduces the performance decline of the magnetic material caused by debris pollution, and reduces the spraying defects such as uneven coating and reduced adhesion, effectively improves the spraying quality, and reduces the rate of defective products.

[0037] The height of the induction plate 130 can be adjusted through the cooperation of the bolt 170, the long circular hole 1201 and the threaded hole 1303. The operation is simple and intuitive, and the height can be accurately adjusted to meet the needs of magnetic materials of different thicknesses. The telescopic rod 1501 can flexibly adjust the distance between the clamping plates 120, so that the clamp can adapt to magnetic materials of different widths or thicknesses, improve the universality of the clamp, and reduce the cost of enterprise equipment procurement.

[0038] In summary, the above is only the preferred embodiment of the present embodiment, any changes and modifications made in the scope of the patent application of the present embodiment shall be covered by the scope of the present patent.
