[0002] The production process of bearing cages requires the process of cage slope pressing. The current cage slope pressing work is generally completed by a robot. The robot grabs the cage to be sloped and places it on the slope pressing die. Then the stamping mechanism is activated. After the stamping is completed, another group of robots will remove the cage after slope pressing and place it on the conveyor belt for transportation to the next step.

[0003] A Chinese invention patent with publication number CN103433389B discloses a bearing retainer slope pressing process production line, including a first manipulator assembly and a second manipulator assembly. This solution achieves the purpose of transferring the retainer by driving the manipulator to and fro via a rotating device. The installation cost and maintenance cost of the rotating device are significantly lower than those of an expensive ball screw mechanism. However, the use of a manipulator to pick up and place the retainer is only suitable for small retainers, which are light in weight and can be loaded and unloaded by a manipulator. However, for medium and large retainers, the diameter reaches 70 cm and the weight is dozens of times that of a small retainer. This solution is not suitable for medium and large retainers.

[0022] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0023] Embodiment 1 In a typical embodiment of the present invention, reference is made to Figure 1As shown, a medium-to-large bearing retainer slope pressing device includes a stamping machine 1, which is equipped with a slope pressing die 14 and a stamping mechanism 12 above the slope pressing die 14; one end of the support seat 2 is fixed on the workbench of the stamping machine 1, and the other end extends outward and is provided with a propulsion cylinder 3. A fixed seat 71 is slidably provided on the top of the support seat 2, and a tensioning cylinder 8 is provided on the side of the fixed seat 71 away from the slope pressing die 14, and a driven wheel 72 is provided on the other side. A motor 9 is provided on the outer side of the fixed seat 71, and a tensioning shaft 83 of the tensioning cylinder 8 passes through the fixed seat 71 and the driven wheel 72. The motor 9 is connected to the driven wheel 72 through a transmission mechanism. The driven wheel 72 is used to abut the retainer 13, and a clamping block is provided at the end of the tensioning shaft 83. The clamping block is used to abut the pressure block 82. Under the action of the tensioning shaft 83, the pressure block 82 cooperates with the driven wheel 72 to clamp the retainer 13; the propulsion cylinder 3 drives the fixed seat 71 to move so that the retainer 13 is close to the slope pressing die 14 and completes the slope pressing process through the stamping mechanism.

[0024] like Figure 1 As shown, a die mounting seat 11 is provided on the workbench of the punching machine 1, and a slope pressing die 14 is detachably provided on the die mounting seat 11. The slope pressing die 14 is connected to the die mounting seat 11 through a mounting hole at the bottom, and different slope pressing dies 14 can be replaced according to the type of the retainer. The slope pressing die 14 is arranged directly below the punching mechanism 12, and the punching mechanism 12 is the prior art.

[0025] like Figure 1 As shown, one end of the support seat 2 is fixed on the workbench, and the other end extends laterally outward. A transverse slide rail 4 is provided on the top of the support seat 2, and a thrust cylinder 3 is fixed on the outer end of the support seat 2. The output end of the thrust cylinder 3 is connected to a slide seat 5, and the slide seat 5 is provided on the transverse slide rail 4. The thrust cylinder 3 drives the slide seat 5 to slide on the transverse slide rail 4.

[0026] like Figure 1 As shown, a fixed frame 6 is provided on the top of the slide seat 5, and a support frame 7 is slidably provided inside the fixed frame 6, wherein both the fixed frame 6 and the support frame 7 are rectangular frames, the size of the support frame 7 is smaller than that of the fixed frame 6, and the fixed seat 71 is fixed in the support frame.

[0027] A tensioning cylinder 8 is provided on the side of the fixing seat away from the mold mounting seat 11, and a driven wheel 72 is rotatably provided on the side close to the mold mounting seat 11. The end of the driven wheel close to the fixing seat 71 is rotatably matched with the fixing seat 71 through a sleeve structure and a bearing.

[0028] like Figure 1 and Figure 2 As shown, the top of the support frame 7 is connected to an adjusting piece, and the adjusting piece is preferably a pin 62, through which the relative position of the fixed frame 6 and the support frame 7 is achieved.

[0029] A vertical slide rail 61 is provided on the outside of the fixed frame 6, and the motor 9 is slidably installed on the vertical slide rail 61 through a motor mounting seat. A vertical slide rail 61 is also relatively provided on the other side of the fixed frame 6 for slidably installing an origin detection member 15 for detecting the origin of the retaining frame.

[0030] It is understandable that the motor 9 and the fixed seat 71 are raised and lowered synchronously to achieve the height adjustment of the retaining frame to be pressed. When adjusting the position of the motor and the fixed seat, it is necessary to fix their positions. Pin holes are provided at corresponding positions on the fixed frame 6 and the support frame 7 of this embodiment, and the motor 9 and the fixed seat 71 are fixed after the height adjustment through the pin shaft. The pin shaft is used for positioning to prevent the motor 9 and the fixed seat 71 from rising and falling.

[0031] The driven wheel of this embodiment is rotatably matched with the fixing seat, and the outer side of the driven wheel 72 is matched with the driving wheel at the output end of the motor 9 through a belt 91.

[0032] like Figure 1 and Figure 3 As shown, the tensioning shaft of the tensioning cylinder 8 passes through the fixed seat 71 and the driven wheel 72. A clamping block is provided at the end of the tensioning shaft. The clamping block is circular and has a radius larger than the diameter of the tensioning shaft. The clamping block is used to cooperate with the pressing block. Figure 3 As shown, the main body of the pressure block 82 is a circular block with a notch at one place. By setting the notch, the pressure block can be clamped on the tensioning shaft. The radius of the pressure block is larger than the radius of the clamping block. After the center position of the retaining frame is sleeved on the tensioning shaft, the pressure block 82 is sleeved on the tensioning shaft 83 from the inner side of the retaining frame 13, and then the tensioning cylinder 8 is pulled backward, so that the clamping block pushes the pressure block 82 to cooperate with the driven wheel 72 to clamp the retaining frame 13. After that, the driven wheel 72 rotates to drive the retaining frame 13 to rotate synchronously. It can be understood that the tensioning shaft 83 is set as two rotatable sections, and the section with the clamping block is rotatably matched with the section connected to the output end of the tensioning cylinder 8 through the bearing to ensure that the retaining frame can rotate smoothly.

[0033] It also includes a control unit installed on the side of the punching machine to control the slope pressing work. The height of the origin detection member 15 is the same as the height of the tension shaft 83. When the servo motor 9 rotates the product, the origin of the material is detected by the origin detection member 15, so as to facilitate the determination of the initial position of the rotation of the retainer, and then the angle can be rotated in sequence to stamp each rib position of the product step by step. The setting of the origin detection member 15 ensures the accuracy of the position of the retainer during the first stamping. The origin detection member 15 can use a laser sensor.

[0034] The medium and large bearing retainer slope pressing device of this embodiment can realize the slope pressing of medium and large retainers. When the model or size of the medium and large retainers changes, the height of the motor and the fixed seat can be adjusted, so as to adjust the height of the retainer after clamping accordingly, to ensure that the position of the retainer to be stamped corresponds to the position of the slope pressing mold when stamping.

[0035] Embodiment 2 In a typical embodiment of the present invention, reference is made to Figure 1-Figure 3 As shown, a slope pressing method for a medium-to-large bearing cage adopts the slope pressing device for the medium-to-large bearing cage described in the first embodiment, and comprises the following steps: The retainer is installed on the tensioning shaft, and then the pressure block is installed. The tensioning cylinder 8 drives the tensioning shaft to tighten backward to realize that the clamping block pushes the pressure block backward, and finally the pressure block and the driven wheel clamp the retainer; the motor 9 drives the retainer to rotate, and the origin detection part is used to detect the origin of the material, so as to facilitate the determination of the initial position of the retainer rotation, so as to achieve the purpose of adjusting the position of the retainer to be pressed, and then the angle can be rotated in sequence to stamp each rib position of the product step by step; the retainer is rotated at the specified angle and the stamping steps are carried out in sequence.

[0036] The slide is driven to move by the thrust cylinder, and then the retainer is moved to the slope pressing die. The stamping mechanism 2 presses down to perform slope pressing, and each rib position of the product is stamped step by step by rotating the angle in sequence. After all the stamping is completed, the thrust cylinder drives the retainer to return, and the tensioning cylinder loosens the retainer, and the retainer can be removed.

[0037] When the size of the cage changes, the height of the motor and the fixing seat is adjusted, and then the pin shaft is used to limit the position, thereby achieving universal use for medium and large cages of different sizes.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
