[0037] The utility model discloses a conveying device of a retaining frame, which can detect whether the clamping claws fail to clamp. In addition, the utility model also discloses a processing device with the conveying device of the retaining frame.

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0040] Rolling bearings consist of four components: inner ring, outer ring, rolling element and cage. The inner ring is used to match the shaft and rotate with the shaft; the outer ring is used to match the bearing seat and play a supporting role; the rolling element is evenly distributed between the inner ring and the outer ring with the help of the cage, and its shape, size and number directly affect the performance and life of the rolling bearing; the cage plays the role of isolating the rolling element and guiding its movement in the rolling bearing.

[0041] In the cage processing process, the required shape of the cage is usually stamped out from the cage raw material by stamping, and then the stamped cage is subsequently shaped and punched. In the clamping frame processing process, in order to achieve mechanization, the cage is usually transported by a clamping claw to realize the transfer of the cage between different processes.

[0042] like Figure 1 and Figure 2 As shown, the processing device of the retainer includes a machine tool body 2 and a conveying track 1. A processing mold is arranged on the machine tool body 2. In some embodiments, the processing mold includes: a forming mold 21, a shaping mold 22, a punching mold 23 and a nailing mold 24. These molds are arranged in sequence and arranged on the same straight line. The conveying track 1 is arranged in the same direction as the processing mold, and the processing mold and the conveying track 1 overlap in the vertical direction. It can be understood that part of the position of the conveying track 1 is opposite to the processing mold, so that the retainer can be transported between the processing molds through the conveying track 1.

[0043] Combination Figure 3 As shown, the conveying track 1 in some embodiments includes a first conveying track 12, a second conveying track 11, and a third conveying track 13. The second conveying track 11, the first conveying track 12, and the third conveying track 13 are sequentially connected to form a straight track, which passes through the machine tool body 2. A first clamp 15 is provided at the first conveying track 12, a second clamp 14 is provided at the second conveying track 11, and a conveyor belt is provided at the third conveying track 13.

[0044] Combination Figure 6 and Figure 7 As shown, the first conveying track 12 of the conveying device of the retaining frame disclosed in the present application can move along the arrangement direction of the processing mold, and the first conveying track 12 is arranged opposite to the processing mold; the first clamp 15 is installed on the first conveying track 12, moves with the first conveying track 12, and the first clamp 15 can clamp and release the retaining frame, there are multiple first clamps 15, and are arranged in sequence along the mold arrangement direction in the processing mold, along the arrangement direction of the first clamps 15, the distance between adjacent first clamps 15 is the same as the distance between adjacent molds in the processing mold, so as to realize that the first clamp 15 can be arranged one-to-one with the molds in the processing mold (forming mold 21, shaping mold 22, punching mold 23 and nailing mold 24).

[0045] The cage conveying device in the present application also includes a first detection device 153 disposed on the first clamp 15, and the cage on the first clamp 15 is detected when the first clamp is in the startup state, and the first detection device 153 is connected to the machine tool control system. If the first clamp 15 does not clamp the cage when it is in the startup state, it means that the clamping of the first clamp 15 fails, and the first detection device detects that the cage is not clamped on the first clamp 15, and then controls the machine tool to stop working through the control system.

[0046] The conveying device of the retaining rack in the present application is configured with a first detection device on the first clamp 15 of the first conveying track 12 opposite to the processing mold. It can detect whether there is a retaining rack on the first clamp 15 when the first clamp is in a started state, and control the machine tool to stop working when the retaining rack is not detected, so as to prevent the problem of clamping failure of the first clamp.

[0047] It should be noted that the first detection device 153 detects only when the first clamp 15 is in the startup state to avoid the problem of misoperation. The startup process of the first clamp 15 is when the first clamp 15 is clamping. For example, when the clamping parts of the first clamp 15 are close to each other to a preset distance, the first clamp 15 is in the startup state.

[0048] In some embodiments, the first detection device 153 is a detection switch, and when the first clamping jaw 15 clamps the holder, the first detection device 153 is not triggered; when the first clamping jaw 15 does not clamp the holder, the first detection device 153 is triggered. It can be understood by those skilled in the art that the first detection device 153 in the present application can also be other structures, for example, it is an optical coupling sensor, when the first clamping jaw 15 clamps the holder and is located between two photosensitive elements of the optical coupling sensor, the optical coupling sensor is not triggered; and when the first clamping jaw 15 does not clamp the holder, the light between the two photosensitive elements cannot be blocked, and the optical coupling sensor is triggered.

[0049] The specific structure of the first detection device 153 can be set according to different needs. The method of using a detection switch has a simple structure and a low failure rate; while the method of using an optical coupling sensor for detection has a high detection sensitivity and a high accuracy rate of the detection result.

[0050] On the basis of the above technical solution, the conveying device in the present application also includes an alarm device, wherein the alarm device is connected to the first detection device 153, and when the first detection device 153 detects that no retaining frame is provided on the first clamping jaw 15, the alarm device is activated.

[0051] By adding an alarm device, the operator can be reminded to manually intervene in the conveying device. Optionally, the alarm device includes but is not limited to sound and light alarms.

[0052] In some embodiments, the distances between adjacent molds in the processing mold are the same, which can be specifically understood as the distances between adjacent molding molds 21, shaping mold 22, punching mold 23 and nailing mold 24 are the same. On this basis, the distances between adjacent first clamps 15 are the same, so that during the movement of the first clamps 15, all first clamps 15 move the same distance and can reach the next station.

[0053] The first conveying track 12 in the present application includes: a first track and a second track, wherein the first track and the second track are parallel and arranged opposite to each other; the first clamp 15 includes a first side clamp 151 and a second side clamp 152, wherein the first side clamp 151 is arranged on the side of the first track facing the second track, and the second side clamp 152 is arranged on the side of the second track facing the first track, and the first side clamp 151 and the second side clamp 152 are arranged opposite to each other, and the first side clamp 151 and / or the second side clamp 152 have a first detection device 153.

[0054] By providing two first clamping jaws 15 and arranging them opposite to each other, it is convenient to clamp both sides of the holder at the same time, thereby ensuring the stability of the first clamping jaw 15 clamping the holder. The specific structure of the first clamping jaw 15 can be set according to different needs and is within the protection range. When the first side clamping jaw 151 and the second side clamping jaw 152 are clamping, the first clamping jaw 15 is in the starting state.

[0055] On the basis of the above technical solution, the first track and the second track in the present application can move in a relatively distant direction to release the retaining frame clamped by the first side clamp 151 and the second side clamp 152;

[0056] The first track and the second track can move synchronously along the direction of the processing mold arrangement, driving the first side clamp 151 and the second side clamp 152 to move synchronously to transport the holder on the first clamp 15 to the next process and return. The movement of the first track and the second track can be driven by a servo motor.

[0057] During the operation, the first rail and the second rail move away from each other, releasing the clamped retainer so that the retainer is located on the mold of the corresponding processing mold. The upper template of the machine tool body 2 is pressed downward, driving the upper mold of the processing mold (exemplarily, the upper mold of the forming mold 21, the upper mold of the shaping mold 22, the upper mold of the punching mold 23 and the upper mold of the nail piercing mold 24) to move downwardly of the processing mold, and stamping the retainer on the lower mold to complete the corresponding process.

[0058] Exemplarily, the holder on the lower die of the forming die 21 can complete the forming process, the holder on the lower die of the shaping die 22 can complete the shaping process, the lower die of the punching die 23 can complete the punching process, and the lower die of the nailing die 24 can complete the nailing process. During the stamping process, the first track and the second track move in the opposite direction along the arrangement direction of the processing die by a preset distance, which is the distance between adjacent first clamping jaws 15.

[0059] After the processing is completed, the first rail and the second rail are close to each other, and the first side clamp 151 and the second side clamp 152 are close to each other and clamp the corresponding retainer to complete the clamping. After the clamping is completed, the first rail and the second rail move along the arrangement direction of the processing mold by a preset distance, which is the distance between adjacent first clamps 15, and then the first rail and the second rail move away from each other, and the above content is repeated.

[0060] Combination Figure 4 and Figure 5 As shown, the conveying track 1 further includes a second conveying track 11, a second clamping jaw 14 and a second detection device (not shown in the figure).

[0061] Among them, the second conveying track 11 is connected to the first conveying track 12, and is used to convey the retaining frame to the first conveying track 12; the second clamp 14 is installed on the second conveying track 11, and is used to clamp the retaining frame; the second detection device is arranged on the second clamp 14, and can detect the retaining frame on the second clamp 14, and the second detection device is connected to the machine tool control system.

[0062] The accuracy of detection can be further improved by arranging a second detection device on the second clamping jaw 14 of the second conveying track 11. When the retaining rack is not detected on the second clamping jaw 14, the control system reminds the operator to refill the material according to the detection result.

[0063] In some embodiments, the second clamping jaw 14 may not be provided with a detection device to avoid erroneous operation caused by the second clamping jaw 14 when only working at the processing mold.

[0064] It should be noted that in some embodiments, the second detection device has the same structure as the first detection device. Therefore, the structure and detection principle of the second detection device can refer to the above description of the structure and detection principle of the first detection device 153, which will not be repeated here.

[0065] In some embodiments, the retainer in the present application is a retainer of a deep groove ball bearing, and the retainer of the deep groove ball bearing is wavy in shape, which can be understood as an annular member with protrusions (or grooves).

[0066] In addition, the present application also discloses a processing device for a retaining frame, including a processing mold and a conveying device, wherein the conveying device is the conveying device disclosed in the above embodiment. Therefore, the processing device for the retaining frame having the conveying device also has all the above-mentioned technical effects, which will not be repeated here one by one.

[0067] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0068] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
