Description

Technical Field

[0001] This utility model relates to the field of press fitting technology, and in particular to a multi-functional rapid cooling press fitting machine. Background Technology

[0002] A press fitting machine is a mechanical device that uses pressure to press parts into a mold or workpiece.

[0003] A search revealed that Chinese Patent CN109894842A discloses a servo press fitting machine, which includes a press fitting machine body. The press fitting machine body is equipped with a press fitting machine cylinder, a press fitting machine compression component, a press fitting machine guide component, and a press fitting machine platform. The piston rod end of the press fitting machine cylinder is connected to the press fitting machine compression component, and the cylinder end of the press fitting machine cylinder is connected to the press fitting machine body. The press fitting machine guide component passes through the press fitting machine platform, and the press fitting machine cylinder drives the press fitting machine compression component to move.

[0004] Although the aforementioned servo press machine can press workpieces by controlling the extension of the cylinder, the stroke of the cylinder depends on the air source pressure and the limiting mechanism. The compressibility of compressed air causes the piston to be unable to accurately stop at the preset position. The compressed air will undergo elastic deformation, which directly causes deviation in the pressing stroke and reduces the pressing accuracy. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a multifunctional rapid cooling press-fitting machine, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-functional rapid cooling press-fitting machine includes a mounting frame, on which a press-fitting device is provided, and the press-fitting device includes a clamping part.

[0008] The clamping part includes a first motor, a connecting rod and a clamping plate. The top surface of the first motor is fixedly connected to the inner wall of the mounting frame. A limit slider is slidably connected to the inner wall of the clamping plate. An adjustment component is provided between the connecting rod and the adjacent clamping plate. A pressing component is provided on the outer side of the clamping plate.

[0009] The pressing device also includes a power unit;

[0010] The power unit includes a threaded column, a sliding plate, and a pressure block. The bottom surface of the threaded column is fixedly connected to the top surface of the sliding plate. A power component is provided on the left side of the threaded column, and the pressure block is slidably sleeved on the outer surface of the sliding plate.

[0011] Furthermore, the adjustment assembly includes a second slider, a lead screw, and a first slider. A through groove is provided on the outer surface of the mounting frame. The outer surfaces of the first slider and the second slider are slidably connected to the inner wall of the mounting frame. The outer surface of the lead screw is rotatably connected to the outer surface of the first slider through a bearing seat. The inner wall of the second slider is threadedly connected to the outer surface of the lead screw. A positioning nut is threaded onto the outer surface of the lead screw, and the positioning nut is in contact with the outer surface of the second slider. By setting the lead screw, it is convenient to adjust the distance between the first slider and the adjacent second slider, which facilitates the clamping and positioning of workpieces of different proportions.

[0012] Furthermore, the top surface of the first motor is fixedly connected to the inner wall of the mounting bracket, a sleeve is threaded onto the outer surface of the output shaft of the first motor, the outer surface of the bottom end of the connecting rod is hinged to the inner wall of the sleeve, and the top end of the connecting rod is hinged to the bottom surface of the second slider. By setting up the first motor, sleeve, connecting rod and clamping plate, it is convenient to clamp and position the workpiece.

[0013] Furthermore, the extrusion assembly includes rollers, mounting rods, and an extrusion plate. The outer surface of the mounting rod is fixedly connected to the inner wall of the mounting frame, the outer surface of the roller is movably connected to the inner wall of the mounting rod, and the bottom surface of the clamping plate is fixedly connected to the top surface of the extrusion plate. By setting the extrusion plate, mounting rod, and rollers, multiple clamping plates are controlled to move away from each other when loading and unloading workpieces. At this time, the rollers push the extrusion plate downwards, so that the clamping plate moves into the interior of the mounting frame, improving the convenience of use.

[0014] Furthermore, the outer surface of the limiting slider is fixedly connected to the outer surface of the first slider, and a spring is fixedly connected to the inner wall of the clamping plate. The bottom end of the spring is fixedly connected to the top surface of the limiting slider. By setting the spring, when multiple clamping plates approach each other, the elastic force of the spring is used to make the top of the clamping plate extend out of the mounting frame, so as to clamp the workpiece.

[0015] Furthermore, the power unit also includes a threaded sleeve and a limiting post. The threaded sleeve is threaded onto the outer surface of the threaded post. The outer surface of the threaded sleeve is rotatably connected to the inner wall of the mounting frame via a cylindrical roller bearing. A bracket is fixedly connected to the top surface of the limiting post. The inner wall of the mounting frame is fixedly connected to the bracket. The outer surface of the bottom end of the limiting post slides through the top surface of the threaded post and extends into the interior of the threaded post. By setting the threaded post and the threaded sleeve, it is convenient to press the workpiece.

[0016] Furthermore, the power assembly includes a worm gear, a worm, and a second motor. The outer surface of the second motor is fixedly connected to the inner wall of the mounting bracket. The worm gear is fixedly sleeved on the outer surface of the threaded sleeve. The back of the worm is fixedly connected to the front of the output shaft of the second motor. By setting the second motor, the worm, and the worm gear, the pressure block can move up and down easily.

[0017] Furthermore, an external rotor fan is fixedly connected to the top surface of the bracket, and a filter screen is fixedly connected to the inner wall of the mounting frame to facilitate heat dissipation and cooling of the device's interior.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. By cooperating with the power unit, threaded sleeve and threaded column, the movement of the pressure block is made smoother, improving the stability of the pressing process. The use of pressure sensor makes it easy to detect the pressing pressure, which can avoid excessive pressing pressure, which may damage the workpiece, and also avoid insufficient pressing pressure, which may result in incomplete pressing of the workpiece, thereby improving the pressing accuracy.

[0020] 2. By starting the first motor, it is easy to drive the clamping plate to clamp and position the workpiece, thereby improving the stability of the pressing process and thus improving the pressing effect. By adjusting the components, it is easy to adjust the relative positions of multiple clamping plates, so that the device can clamp workpieces with different length and width ratios, thereby improving the adaptability of the device.

[0021] 3. After the workpiece pressing is completed, this utility model only needs to drive the clamping plate away from the workpiece, and through the extrusion component, the clamping plate will automatically move to the bottom of the pressing platform, thereby avoiding the clamping plate from affecting the operator's work and facilitating the loading and unloading of the workpiece.

By starting the first motor 211, the clamping plate 217 can be driven to clamp and position the workpiece, thereby improving the stability of the pressing process and thus improving the pressing effect. By adjusting the components, the relative positions of multiple clamping plates 217 can be adjusted, so that the device can clamp workpieces with different length and width ratios, thereby improving the adaptability of the device.

[0032] An extrusion assembly is provided on the outer side of the clamping plate 217. The extrusion assembly includes a roller 214, a mounting rod 215, and an extrusion plate 216. The outer surface of the mounting rod 215 is fixedly connected to the inner wall of the mounting frame 1, and the outer surface of the roller 214 is movably connected to the inner wall of the mounting rod 215. The bottom surface of the clamping plate 217 is fixedly connected to the top surface of the extrusion plate 216. After the workpiece is pressed, this utility model only needs to drive the clamping plate 217 away from the workpiece. Through the extrusion assembly, the clamping plate 217 is automatically moved to the bottom of the pressing platform, thereby avoiding the clamping plate 217 from affecting the operator's work and facilitating the loading and unloading of the workpiece.

[0033] The pressing device 2 also includes a power unit 22, which includes a threaded post 225, a slide plate 204, and a pressing block 228.

Furthermore, the pressure sensor facilitates the detection of the pressing pressure of the pressing 228, which can avoid excessive pressing pressure, which may damage the workpiece, and also avoid insufficient pressing pressure, which may result in the workpiece not being pressed in place, thereby improving the pressing accuracy.

[0037] In this invention, starting the first motor 211 drives the sleeve 212 to move upward. The sleeve 212 pushes the second slider 201 to move via the connecting rod 213, causing the four second sliders 201 to move away from each other.

The roller 214 pushes the extrusion plate 216 downward, causing the extrusion plate 216 to move the clamping plate 217 downward. This allows the clamping plate 217 to move into the inner side of the mounting frame 1, whereby the workpiece can be placed. On the outer surface of the mounting bracket 1, the first motor 211 is started, causing the sleeve 212 to move downward, so that the clamping plate 217 clamps the outer surface of the workpiece. The second motor 203 is started, and the output shaft of the second motor 203 drives the worm gear 220 to rotate. The worm gear 220 drives the worm wheel 229 to rotate. The worm wheel 229 drives the threaded sleeve 226 to rotate. The threaded sleeve 226 drives the threaded column 225 to move downward. The threaded column 225 drives the slide plate 204 and the pressure block 228 to move downward, so that the pressure block 228 presses the workpiece.
