Description

Technical Field

[0002] In the manufacturing process of automobile braking system, the precision and quality of caliper components have an important impact on braking performance and safety.

[0003] In the traditional production process of automobile brake calipers, grinding is one of the key process steps to ensure the dimensional accuracy and surface quality of caliper parts. However, in the actual production process, due to factors such as human operation errors, equipment failures or system control errors, the caliper parts may be misoperated or the system may mistakenly process them again after grinding, which is the so-called secondary processing. Secondary processing will not only reduce the dimensional accuracy of the caliper parts, but may even damage the parts and affect the overall performance of the brake system. Secondary processing will also increase production costs, reduce production efficiency, and cause unnecessary economic losses to the company. For this reason, we propose a device to prevent secondary processing for automobile brake caliper production. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1

[0022] Please refer to Figures 1-4 As shown in the figure, the present utility model provides a device for preventing secondary processing in the production of automotive brake calipers, which includes a processing table 1 and a rotatable turntable 8. A linear motor 2 is installed on the top surface of the processing table 1. An installation rod 3 is installed at the mobile end of the linear motor 2. A U-shaped mounting plate 4 is installed on one side of the installation rod 3. A grinding assembly is arranged on the inner side of the surface of the U-shaped mounting plate 4. A contact rod 7 is welded on one side of the U-shaped mounting plate 4;

[0023] The turntable 8 is located above the processing table 1. A plurality of positioning molds 9 are installed on the surface of the turntable 8. A chute 11 is opened inside the positioning mold 9. A sliding plate 12 is slidably installed inside the chute 11. One side of the sliding plate 12 is provided with an inclined surface. The contact rod 7 is used to contact the inclined surface of the sliding plate 12. A plurality of light-transmitting holes 10 are opened on the surface of the turntable 8. The opening positions of the light-transmitting holes 10 correspond to the installation positions of the positioning molds 9. A photosensitive sensor 13 is embedded on the top surface of the processing table 1.

[0024] Specifically, during the processing, the contact rod 7 contacts the sliding plate 12 to block the light of the photosensitive sensor 13. If secondary processing is performed on the already ground component due to an operation error, since the photosensitive sensor 13 is blocked, the controller cannot control the linear motor 2 and the motor 5 to open, effectively avoiding secondary processing and ensuring the processing accuracy of the brake caliper.

[0025] Among them: The grinding assembly includes a motor 5. The motor 5 is installed outside the U-shaped mounting plate 4. The output end of the motor 5 movably penetrates through the U-shaped mounting plate 4. A grinding wheel 6 is fixedly installed at the output end of the motor 5. One side of the grinding wheel 6 is rotatably installed on one side inside the U-shaped mounting plate 4. Turning on the switch of the motor 5 can drive the grinding wheel 6 to rotate.

[0026] Among them: The motor 5, the linear motor 2 and the photosensitive sensor 13 are all electrically connected to the controller of the device. The controller receives the signal of the photosensitive sensor 13 and can judge whether the motor 5 and the linear motor 2 can be opened according to the information transmitted by the photosensitive sensor 13.

[0027] Among them: The cross-section of the sliding plate 12 is in the shape of a right trapezoid. The sliding plate 12 and the chute 11 are properly sized and matched, and the sliding plate 12 can slide inside the chute 11.

[0028] Among them: A clamping structure for fixing the automotive brake caliper component inside the positioning mold 9 is installed on the surface of the positioning mold 9. The clamping structure can fix the caliper component arranged inside the positioning mold 9.

[0029] Working principle: The utility model is a device for preventing secondary processing in the production of automotive brake calipers. A clamping structure can be arranged on the surface of the positioning die 9 to fix the automotive brake caliper components on the surface of the positioning die 9. During use, the turntable 8 drives the positioning die 9 to rotate to an appropriate position. At this time, the photosensitive sensor 13 is not blocked by the turntable 8 and the sliding plate 12, so it can sense light normally. The photosensitive sensor 13 can transmit a signal to the controller, and the controller can control the linear motor 2 and the motor 5 to turn on. The motor 5 drives the grinding wheel 6 to rotate, and the linear motor 2 drives the mounting rod 3 and the U-shaped mounting plate 4 to move. The U-shaped mounting plate 4 drives the grinding wheel 6 to move and grind the caliper components. When the U-shaped mounting plate 4 moves, it can drive the abutting rod 7 to move. The abutting rod 7 abuts against the inclined surface of the sliding plate 12, so that one end of the sliding plate 12 with the inclined surface installed enters the chute 11, and the other end extends out of the chute 11. The sliding plate 12 extending out of the chute 11 can shield the photosensitive sensor 13;

[0030] After a single grinding is completed, it is necessary to rotate the turntable 8 to continue grinding. If secondary processing of the already ground components is caused by an operation error, since the photosensitive sensor 13 is shaded, the controller cannot control the linear motor 2 and the motor 5 to turn on, effectively avoiding secondary processing. And if the photosensitive sensor 13 is blocked by the turntable 8, the positioning die 9 on the surface of the turntable 8 is not rotated to the appropriate processing position, which can improve the processing safety of the device.

[0031] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0032] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
