Description

Technical Field

[0001] This utility model relates to the field of bearing heat treatment technology, and in particular to a heat treatment device for stainless steel bearings. Background Technology

[0002] Through a proper heat treatment process, stainless steel bearings can achieve ideal mechanical properties, such as a balance of hardness, strength, and toughness, as well as high wear resistance and corrosion resistance. This enables the bearings to withstand greater loads and higher speeds, and to have a longer service life and better reliability, thus improving their mechanical properties and wear resistance.

[0003] In the traditional bearing heat treatment process, workers typically use tools (such as clamps, pliers, and clamps) to place the bearings one by one into the heat treatment water tank for annealing. This process is problematic because it reduces production efficiency by manually handling the workpieces and exposes workers to the high temperatures of the annealing water tank, increasing the risk of burns and other safety accidents. Therefore, this invention proposes a stainless steel bearing heat treatment device to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the problems in the traditional bearing heat treatment process, which typically involves workers using tools (such as clamps, pliers, and clamps) to place the bearings one by one into a heat treatment water tank for annealing. This is problematic because manually handling the workpieces reduces production efficiency, and workers' frequent contact with the high-temperature annealing water tank can easily lead to burns and other safety accidents. Therefore, this invention proposes a stainless steel bearing heat treatment device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A heat treatment apparatus for stainless steel bearings, comprising:

[0007] Base plate;

[0008] A heat treatment chamber, wherein the heat treatment chamber is located on top of the base plate, and the number of heat treatment chambers is three;

[0009] A loading platform is fixedly installed on the left side of the top of the base plate;

[0010] A material unloading platform is fixedly installed on the right side of the top of the base plate;

[0011] A support plate, wherein the rear side of the top of the base plate is fixedly connected to the support plate;

[0012] Top plate, the top of the support plate is fixedly connected to the top plate;

[0013] A conveying mechanism, located on top of the support plate, is used to convey workpieces.

[0014] A clamping mechanism is located at the bottom of the conveying mechanism and is used to position the workpiece.

[0015] As a preferred embodiment of this utility model, the conveying mechanism includes: a housing, a first motor lead screw, a threaded sleeve, and an electric push rod;

[0016] The housing is fixedly installed on the front side of the bottom of the top plate. The first motor is fixedly installed on the left side of the inner cavity of the housing. The output end of the first motor is fixedly connected to the lead screw. The right side of the lead screw is rotatably connected to the right side of the inner cavity of the housing through a rotating shaft. The threaded sleeve is movably sleeved on the surface of the lead screw. The bottom of the threaded sleeve penetrates the housing and is fixedly connected to the electric push rod.

[0017] As a preferred embodiment of this utility model, the clamping mechanism includes: a housing, a transmission frame, a transmission plate, a guide wheel, a clamping plate, a second motor, and a threaded rod;

[0018] The housing is fixedly installed at the bottom of the electric push rod output shaft. The bottom of the housing has an opening. The transmission frame is slidably installed at the bottom of the housing cavity. The top of the transmission frame has a threaded hole. The front and rear sides of both sides of the transmission frame have inclined grooves. The front and rear sides of the opening cavity are slidably connected to the transmission plate. The top of the transmission plate extends through the inner cavity of the transmission frame. Both sides of the transmission plate are rotatably connected to guide wheels. There are four guide wheels. The end of the guide wheel away from the transmission plate extends through the inner cavity of the inclined groove. The bottom of the two transmission plates on opposite sides is fixedly connected to the clamping plate. The second motor is fixedly installed at the top of the housing cavity. The output end of the second motor at the bottom is fixedly connected to the threaded rod. The bottom of the threaded rod extends through the inner cavity of the transmission frame. The surface of the threaded rod is threadedly connected to the threaded hole.

[0019] As a preferred embodiment of this utility model, a limiting port is provided at the bottom of the housing, and the limiting port is adapted to the threaded sleeve.

[0022] Beneficial effects:

[0023] 1. By starting the first motor to drive the lead screw to rotate, the lead screw then drives the threaded sleeve and electric push rod to move, which can facilitate the conveying of the workpiece. Activating the electric push rod sinks the workpiece into the heat treatment box for heat treatment. The automation level is high, which improves the heat treatment efficiency.

[0024] 2. By turning on the second motor, the threaded rod is driven to rotate. The threaded rod engages with the threaded hole and drives the transmission frame to move. When the transmission frame moves, it engages with the guide wheel through the inclined groove and drives the transmission plate and clamping plate to move. This allows workpieces of different sizes to be clamped and fixed without the need for workers to use tools to move the workpieces, thus improving the safety of workpiece heat treatment.

[0025] In this invention, by using the clamping mechanism and the conveying mechanism in combination, workpieces of different specifications can be fixed and conveyed to heat treatment chambers of different temperatures for heat treatment, thereby improving the efficiency of workpiece heat treatment and enhancing the safety of heat treatment processing.
