Description

Technical Field

[0001] The utility model relates to the technical field of knife strip processing, in particular to a clamp for loading knife strips. Background Art

[0002] The fixture for loading the blade is usually called a blade fixture, which is used to stabilize the blade for installation, replacement or maintenance. This fixture usually consists of a clamping device, an adjustment device and a fixing device, and can be designed and manufactured according to the size and shape of the blade. However, the blade needs to be coated to improve the hardness of the blade and the wear resistance of the surface, thereby extending the service life of the blade.

[0003] The traditional fixture for loading the blade is hung on the fixture bracket of the coating equipment during coating, ensuring that the fixture is stable and the blade can be fully exposed to the paint, and the paint is evenly applied on the surface of the blade manually;

[0004] The traditional fixture for loading knife strips has the following problems: when manually applying paint, there may be problems of uneven coating and inconsistent thickness, which depends more on the skills and experience of the operator. For this reason, we propose a fixture for loading knife strips. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a clamp for loading a knife strip, thereby avoiding uneven thickness or coating leakage, improving coverage and uniformity, and effectively solving the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamp for loading a blade, comprising a mounting seat and a clamping mechanism;

The left end of the rotating shaft is fixedly connected to the turntable. A sliding groove is provided on the left side of the turntable. Clamping plates are slidably connected to the front and rear ends of the inner wall of the sliding groove respectively. The opposite inner sides of the two clamping plates are provided with evenly distributed anti-skid grooves. A clamp is provided between the two clamping plates to enable the knife strip fixed on the clamp to realize orbital revolution, which helps to form a more uniform coating, avoid uneven thickness or missing coating, and improve coverage and uniformity.

[0009] Furthermore, it also includes a single-chip microcomputer, which is arranged on the front side of the upper surface of the left end of the mounting seat, and the input end of the single-chip microcomputer is electrically connected to an external power supply to facilitate the regulation of electrical operation.

[0010] Furthermore, the clamping mechanism also includes a guide slide, a gear, a rack plate and a rotating shaft. The guide slides are opened on the inner walls at the upper and lower ends of the slide. The inner walls of the guide slides are slidably connected with rack plates. The left end of the upper rack plate is fixedly connected to the front side surface of the rear clamping plate, and the right end of the lower rack plate is fixedly connected to the rear side surface of the front clamping plate. The rotating shaft is rotatably connected to the middle part of the inner wall of the slide. A gear is fixedly sleeved on the outer surface of the left end of the rotating shaft. The outer surface of a gear is meshed with the inner tooth grooves of the two rack plates to provide more precise transmission.

[0011] Furthermore, the clamping mechanism also includes a screw and a fixed plate, the fixed plate is fixedly connected to the front end of the left side of the turntable, the internal thread of the fixed plate is connected to the screw, the rear end of the screw is rotatably connected to the front side of the front clamping plate, and the characteristics of the thread prevent it from loosening after clamping.

[0012] Furthermore, the clamping mechanism also includes a knob, which is fixedly connected to the front end of the screw rod to drive the fixing clamp.

[0013] Furthermore, the clamping mechanism also includes a small-diameter gear, a large-diameter gear and a rotating shaft. The rotating shaft is rotatably connected to the bottom of the mounting seat. A small-diameter gear is fixedly sleeved on the left side of the outer surface of the rotating shaft. The large-diameter gear is fixedly sleeved on the outer surface of the rotating shaft. The left side of the large-diameter gear is fixedly connected to the right side of the turntable. The large-diameter gear is meshed with the small-diameter gear to reduce speed and prevent uneven coating due to excessive rotation speed.

[0014] Furthermore, the clamping mechanism also includes a motor, which is installed at the bottom end of the right side surface of the mounting seat by bolts, the left end of the output shaft of the motor is fixedly connected to the right end of the rotating shaft, and the input end of the motor is electrically connected to the output end of the single-chip microcomputer to drive the clamping mechanism to perform orbital coating.

[0015] Compared with the prior art, the beneficial effects of the utility model are: the clamp for loading the blade has the following advantages:

[0016] The clamp is placed between the two clamps by holding the clamp, and then the knob is rotated. The knob drives the screw rod to rotate. The screw rod is threadedly connected to the fixing plate and rotates with the front side of the front clamp. When the screw rod moves backward, it drives the front clamp to move backward by sliding in the slide groove. The clamp moves backward and drives the rack plate to slide in the guide slide groove, and moves backward synchronously with the clamp. The rack plate moves backward and meshes with the gear and rotates. When the rack plate at the top moves backward and meshes with the gear and rotates, the transmission action of the gear will cause the rack plate at the bottom to move forward, thereby driving the two clamps to move toward the middle until they are close to each other. Until it contacts and squeezes the outer surface of the fixture, the fixture is fixed between the two clamping plates to facilitate stability during subsequent coating, and then the motor operation is regulated by the single-chip microcomputer. The output shaft of the motor drives the rotating shaft to rotate, and the rotating shaft drives the small-diameter gear to rotate. The small-diameter gear meshes and rotates with the large-diameter gear, thereby driving the rotating shaft and the turntable to rotate, ensuring that the appropriate torque and speed provided by the motor are transmitted to the turntable to prevent the speed from being too high. Therefore, during the coating process, the knife strip fixed on the fixture can realize orbital revolution, which helps to form a more uniform coating, avoid uneven thickness or missing coating, and improve coverage and uniformity.
