Description

Technical Field

[0001] The utility model belongs to the technical field of coating clamping fixtures, and in particular relates to a valve mold coating fixture. Background Art

[0002] The coating on the engine valve has a variety of special properties that can protect the valve and ensure its smooth transportation. Specifically, the coating can effectively prevent dust adhesion and static electricity accumulation, which is crucial for keeping the valve clean and preventing malfunctions caused by static electricity. The coating can also reduce the adhesion of colloidal substances, which is important for preventing valve clogging and sticking. In addition to the function of the coating itself, the valve shaft is also coated with a layer of special lubricant to further ensure the smooth operation of the valve. At present, the valve coating operation generally uses a magnet block to adsorb the bottom of the mold for clamping. The valve is directly adsorbed on the magnet block at the bottom. If the magnet block breaks during repeated clamping, it will contaminate the valve product. Moreover, as the magnetism of the magnet block decays, the adsorption becomes weaker, and the valve product can easily fall off during the coating process, causing losses. The magnet block fixture can generally only clamp valve products of fixed size, with poor versatility and insufficient utilization. Therefore, it is necessary to improve the existing valve coating fixture. Utility Model Content

[0003] In response to the above problems and technical requirements, the utility model provides a valve mold coating fixture that can eliminate the influence of the state of the magnet on the clamped product, improve the adaptability of the fixture to valve products of different sizes, and improve the versatility of the fixture.

[0004] The technical solution of the present utility model is as follows: A valve mold coating fixture includes a bottom connecting seat, a top connecting seat, a magnetic integrated plate and a workpiece clamping plate. The top connecting seat and the bottom connecting seat are connected by a magnetic integrated plate and a workpiece clamping plate. The magnetic integrated plate and the workpiece clamping plate are arranged in parallel. A plurality of loading holes are provided on the workpiece clamping plate. The valve workpiece is inserted into the loading holes for clamping, and the bottom of the valve workpiece is adsorbed and fixed on the magnetic integrated plate. Two spacing adjustment slides are provided on the top connecting seat and the bottom connecting seat respectively. The two ends of the magnetic integrated plate and the workpiece clamping plate are detachably connected to the spacing adjustment slides by bolts, and the clamping spacing between the magnetic integrated plate and the workpiece clamping plate is adjustable. In this solution, the spacing between the magnetic integrated plate and the workpiece clamping plate is adjustable. When clamping, the spacing between the two can be adjusted to adapt to products of different sizes, thereby solving the problem of poor versatility of the fixture. In addition, since the workpiece clamping plate is detachably connected to the bottom connecting seat and the top connecting seat, workpiece clamping plates of different specifications can be replaced according to the diameter of the valve workpiece, further improving the versatility of the fixture.

[0005] Furthermore, the magnetic integrated plate includes a magnetic plate, a magnetic plate base plate and a magnetic plate cover plate. The magnetic plate is magnetic. Both ends of the magnetic plate are connected to the spacing adjustment slots. The bottom surface of the magnetic plate is attached with a magnetic plate base plate, and the upper surface of the magnetic plate is attached with a magnetic plate cover plate. The magnetic plate cover plate, the magnetic plate and the magnetic plate base plate are fixedly connected by a circle of screws, and the bottom of the valve workpiece is adsorbed on the magnetic plate cover plate.

[0006] Furthermore, the magnetic plate includes a fixed frame and circular magnetic pieces. The area enclosed by the fixed frame is rectangular. The fixed frame is filled with circular magnetic pieces in an array structure. A circle of screw holes is provided along the fixed frame. The magnetic plate cover and the magnetic plate bottom plate are respectively connected to the top and bottom surfaces of the fixed frame. The magnetic plate cover and the magnetic plate bottom plate enclose all the circular magnetic pieces inside.

[0007] In the above scheme, the circular magnetic pieces are enclosed by a magnetic plate bottom plate and a magnetic plate cover plate, so that the magnetic circular magnetic pieces will not come into contact with the workpiece, and will not contaminate the product due to breakage, thereby reducing the risk of product contamination. After disassembling the magnetic plate bottom plate or the magnetic plate cover plate, the circular magnetic pieces can be replaced, and some circular magnetic pieces with weakened magnetism or damage can be replaced, so that the magnetic plate maintains a stable adsorption state, reducing the risk of product falling.

[0008] Furthermore, two grooves are provided on the end faces of both ends of the fixed frame, and two locking blocks are welded in the two grooves. The thickness of the locking block is greater than the thickness of the fixed frame. A transverse locking screw hole is provided in the locking block. The locking block is arranged corresponding to the spacing adjustment slot, and the locking screw hole is opposite to the spacing adjustment slot. The locking screw hole and the spacing adjustment slot are locked by bolts.

[0009] Furthermore, two end faces of the workpiece clamping plate are also provided with two grooves, rectangular blocks are welded in the grooves, the rectangular blocks are arranged correspondingly to the locking blocks, and the middle of the rectangular blocks is also provided with screw holes corresponding to the spacing adjustment slots.

[0010] Furthermore, a circular raised base is provided at the center of the bottom surface of the bottom connecting seat.

[0011] Furthermore, a fixed support shaft is provided at the center of the top surface of the top connecting seat.

[0012] The beneficial effects of the present invention are: 1) The structure of the fixture is simple, and the clamping distance between the workpiece clamping plate and the magnetic integrated plate is adjustable, which can adapt to products of different sizes, thereby improving the versatility and compatibility of the fixture; 2) The magnetic integrated plate seals the circular magnetic piece inside, and the magnetic plate cover and the magnetic plate bottom plate protect the magnetic plate from both sides. The workpiece contacts the magnetic plate cover plate instead of directly contacting the magnetic plate, which can eliminate the risk of contaminating the product after the magnet is broken; 3) The circular magnetic piece that provides magnetism can be replaced. When the magnetism weakens, a stable adsorption force can be maintained by replacing the circular magnetic piece, which can eliminate the risk of the product falling during the clamping process. Moreover, since the circular magnetic piece does not directly contact the workpiece, it is not easily damaged after long-term use. Therefore, the fixture has a long service life and low maintenance frequency, thereby improving the clamping efficiency and reducing the production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-5 The figure shows a valve mold coating fixture of the utility model, which includes a bottom connecting seat 4, a top connecting seat 1, a magnetic integrated plate 3 and a workpiece clamping plate 2. The top connecting seat 1 and the bottom connecting seat 4 are connected by the magnetic integrated plate 3 and the workpiece clamping plate 2. The magnetic integrated plate 3 and the workpiece clamping plate 2 are arranged in parallel. A plurality of loading holes 21 are provided on the workpiece clamping plate 2. The valve workpiece is inserted into the loading hole 21 for clamping, and the bottom of the valve workpiece is adsorbed and fixed on the magnetic integrated plate 3.

[0021] The magnetic integrated plate 3 includes a magnetic plate 32, a magnetic plate base 33, and a magnetic plate cover 31. The magnetic plate 32 is magnetic, and both ends of the magnetic plate 32 are connected to the spacing adjustment slot 5. The magnetic plate base 33 is attached to the bottom surface of the magnetic plate, and the magnetic plate cover 31 is attached to the upper surface of the magnetic plate 32. The magnetic plate cover 31, the magnetic plate 32, and the magnetic plate base 33 are fixedly connected by a circle of screws, and the bottom of the valve workpiece is adsorbed on the magnetic plate cover 31. The magnetic plate 32 includes a fixed frame 321 and circular magnetic pieces 322. The area enclosed by the fixed frame 321 is rectangular. The fixed frame 321 is filled with circular magnetic pieces 322 in an array structure. A circle of screw holes is provided along the fixed frame 321. The magnetic plate cover 31 and the magnetic plate base 33 are respectively connected to the top and bottom surfaces of the fixed frame 321. The magnetic plate cover 31 and the magnetic plate base 33 enclose all the circular magnetic pieces 322.

[0022] The circular magnetic piece 322 is enclosed in the magnetic plate bottom plate 33 and the magnetic plate cover plate 31, so that the magnetic circular magnetic piece 322 will not come into contact with the workpiece, and will not contaminate the product due to breakage, thereby reducing the risk of product contamination. After disassembling the magnetic plate bottom plate 33 or the magnetic plate cover plate 31, the circular magnetic piece 322 can be replaced to replace some circular magnetic pieces 322 with weakened magnetism or damage, so that the magnetic plate 32 maintains a stable adsorption state, reducing the risk of product falling.

[0023] Two spacing adjustment slots 5 are provided on the top and bottom connecting bases 1 and 4, respectively.

The rectangular blocks 22 are arranged corresponding to the locking blocks 324, and the middle portion of the rectangular blocks 22 is also provided with a screw hole corresponding to the spacing adjustment slots 5. The distance between the magnetic integrated plate 3 and the workpiece clamping plate 2 is adjustable. During clamping, the distance between the two can be adjusted to adapt to products of different sizes, solving the problem of poor versatility of the fixture; in addition, since the workpiece clamping plate 2 and the bottom connecting seat 4 and the top connecting seat 1 are all detachably connected, workpiece clamping plates of different specifications can be replaced according to the diameter of the valve workpiece, further improving the versatility of the fixture.
