Description

Technical Field

[0001] The present application relates to the technical field of clamping equipment, and in particular to a resistor quick clamping device. Background Art

[0002] Thick film resistors are commonly used in the manufacture of precision resistors and power resistors. Thick film resistors are mainly made by screen printing. The resistor slurry is coated on the alumina ceramic substrate by screen printing. Commonly used thick film resistors are made by printing and sintering metal ruthenium resistor slurry. Therefore, in the manufacturing process of thick film resistors, they need to be placed in an oven for baking and sintering. When the current thick film resistors enter the oven, they are bolted to the hanging plate, and then the hanging plate is placed in the oven. After baking, the material is taken out of the oven and the bolts are removed. The operation is cumbersome and inefficient. Utility Model Content

[0003] In order to improve operating efficiency, the present application provides a resistor quick clamping device.

[0004] The present application provides a resistor quick clamping device that adopts the following technical solution:

[0005] A resistor quick clamping device includes a fixed seat, a fixed ring and a spring claw, wherein a first installation cavity is opened on the side of the fixed seat, the spring is installed in the first installation cavity, the fixed ring is installed on the fixed seat at the opening of the first installation cavity, the side of the spring retaining spring abuts against the side of the fixed ring, and the fixed seat is provided with a driving member for driving the spring claw to deform.

[0006] By adopting the above technical solution, a spring claw is provided on the fixing seat, and the fixing seat is installed on the tray. When the thick film resistor needs to be clamped, the thick film resistor is clamped in the spring claw. When it needs to be disassembled, the spring claw is driven by the driving member to swing around the swing fulcrum, so that the installation opening of the spring claw becomes larger, thereby facilitating the removal of the thick film resistor, thereby improving the operating efficiency.

[0007] Optionally, a vent is formed on a side of the fixing seat away from the first installation cavity, and the vent is connected to the first installation cavity.

[0008] By adopting the above technical solution, a vent is provided, and the vent is connected to the first installation cavity, so as to improve the baking effect.

[0009] Optionally, the driving member is a release cover, which is slidably connected to the fixing seat along the axial direction of the fixing seat, and the release cover has an abutment ring, which abuts against the spring claw.

[0010] By adopting the above technical solution, the release cover is provided with an abutment ring. When the workpiece needs to be disassembled, the release cover is pressed, and the abutment ring forces the elastic sheet on the spring claw to deform, so that the installation opening of the spring claw becomes larger, so as to facilitate the removal of the workpiece.

[0011] Optionally, the side surface of the abutment ring close to the spring claw has a wedge-shaped surface, and the wedge-shaped surface is inclined from the side close to the spring claw to the side away from the spring claw along the axial direction away from the abutment ring.

[0012] By adopting the above technical solution, when the abutment ring forces the spring claw to deform, the closer the elastic sheet is to the axis of the spring claw, the greater the deformation occurs. Therefore, a wedge surface is provided on the abutment ring to better press the spring claw to deform.

[0013] Optionally, the abutment ring has a hooking portion on one side close to the wedge surface, and the fixing ring has a lap block close to the abutment ring, and the lap block and the fixing ring form a lap step for the hooking portion to lap.

[0014] By adopting the above technical solution, a hooking portion is provided on the abutting ring, and the hooking portion is hooked on the overlapping step on the overlapping block, thereby limiting the release cover and reducing the possibility of the release cover being separated from the fixing seat.

[0015] Optionally, a limiting assembly for limiting the fixing ring is provided at the opening of the first mounting cavity of the fixing seat, the limiting assembly includes a blocking plate and an elastic member forcing the blocking plate to rotate to a position to block the fixing ring, the blocking plate is provided with a rotating shaft, the rotating shaft is rotatably connected to the fixing seat, the elastic member is a torsion spring, the torsion spring is coaxially sleeved on the rotating shaft, one end of the torsion spring is connected to the fixing seat, and the other end of the torsion spring is connected to the blocking plate.

[0016] By adopting the above technical solution, after the fixing ring is installed on the fixing seat, the torsion spring forces the blocking plate to rotate, thereby limiting the position of the fixing ring to achieve the installation of the fixing ring.

[0017] Optionally, a joystick is provided on a side of the blocking plate away from the rotating shaft, and the release cover is provided with an avoidance groove for avoiding the joystick.

[0018] By adopting the above technical solution, a joystick is arranged on the blocking plate so as to facilitate the rotation of the limit plate by the joystick, and an avoidance groove for avoiding the joystick is arranged on the release cover.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. When the workpiece needs to be disassembled, press the release cover, and the abutment ring forces the elastic sheet on the spring claw to deform, so that the installation opening of the spring claw becomes larger, so as to facilitate the removal of the workpiece;

[0021] 2. After the fixing ring is installed on the fixing seat, the torsion spring forces the blocking plate to rotate, thereby limiting the fixing ring to achieve the installation of the fixing ring. BRIEF DESCRIPTION OF THE DRAWINGS
