Description

Technical Field

[0001] This utility model belongs to the technical field of protective devices, specifically, it relates to a protective device for an active measuring instrument for grinding. Background Technology

[0002] An active measuring instrument for grinding is an online measuring instrument used in manual grinding machines, primarily measuring the outer diameter parameters of workpieces. This equipment consists of a measuring device (including a manual measuring device), a drive device, and a controller. The controller employs DSP (Digital Signal Processor) technology and has functions for rough grinding, fine grinding, finishing grinding, and dimensional signal output. The finishing of motor rotor shafts requires grinding, and the dimensional changes of the motor rotor shaft need constant monitoring to prevent over-machining. Therefore, an active measuring instrument for grinding is used in the machining of motor rotor shafts. Application number CN201310535489.8 discloses an automatic calibration device for grinding motor rotor shafts. The active measuring instrument is typically mounted on the grinding machine frame and is not removed even when the machine is stopped. However, the high dust content in machining workshops and long-term exposure to the external environment can affect the adjustment position and the detection mechanism.

[0003] In view of this, this utility model is proposed. Utility Model Content

Side sliding grooves 2 are correspondingly provided on both sides of the fixed mounting base 1. A movable bracket 3 is installed within the side sliding grooves 2. The upper end of the movable bracket 3 is fixedly connected to the outer side of the movable frame 5 via a fixed connecting rod 25. An opening and closing top plate 7 is provided on the top of the movable frame 5. A telescopic cover 6 is provided at the connection point between the opening and closing top plate 7 and the movable frame 5. An upper sliding groove 16 is provided on the top surface of the fixed mounting base 1. An installation groove 22 is provided on the bottom surface of the movable frame 5. Multiple sets of movable pulleys 21 are installed within the installation groove 22. The movable pulleys 21 effectively cooperate with the upper sliding groove 16. A locking extension plate 17 is fixedly provided below the movable bracket 3. The locking extension plate 17 is parallel to the outer wall of the fixed mounting base 1. A locking screw 18 is installed on the locking extension plate 17. A wear-resistant anti-slip pad 19 is provided at the end of the locking screw 18. The relative position of the movable bracket 3 and the fixed mounting base 1 can be locked by the locking screw 18.

[0019] The movable support 3 and the side movable slide 2 are respectively equipped with an upper support wheel 20, a side support wheel 23 and a lower support wheel 24. The upper support wheel 20 is engaged with the top wall of the side movable slide 2, the side support wheel 23 is engaged with the side wall of the side movable slide 2, and the lower support wheel 24 is engaged with the bottom of the side movable slide 2, so that the movable support 3 can move stably along the side movable slide 2.

[0020] Two sets of movable supports 3 are provided on one side of the movable frame 5. The cross-section of the side movable slide 2 is a convex structure. Both ends of the side movable slide 2 are provided with end blocks 4. The end blocks 4 are fixedly connected to the fixed mounting base 1 by screws.

[0021] A display instrument 14 is provided on the outer side of one end of the fixed mounting base 1. The display instrument 14 is connected to the detection structure through a signal transmission line 9. A through hole for the signal transmission line 9 is provided on the end plate of the fixed mounting base 1, and a soft sealing sleeve is provided at the through hole.

[0022] A through hole is provided on the end plate of the movable frame 5 near the display instrument 14. A grinding fluid pipe 15 is installed through the through hole. A rotating adjustment seat 8 is fixedly provided on the outside of the movable frame 5. The opening and closing top plate 7 and the movable frame 5 are rotatably connected through the rotating adjustment seat 8. One end of the opening and closing top plate 7 can be rotated relative to the seat for adjustment.

[0023] A support bracket 10 is fixedly installed at one end of the movable frame 5 away from the rotation adjustment seat 8. A support slot 11 is provided on the support bracket 10. The support slot 11 has a U-shaped structure. An end baffle 12 is provided in the support slot 11. A mating groove 13 is provided on the end baffle 12 to match the holding device.

[0024] The working principle of this utility model is as follows: The fixed mounting base 1 of the device is fixedly installed on the frame on the side of the display instrument 14. The position adjustment device of the clamping device of the grinding active measuring instrument is located between the fixed mounting bases 1. According to the installation conditions of the frame, the moving frame 5 and the fixed mounting base 1 can be aligned or misaligned. The position of the moving frame 5 can be adjusted relative to the fixed mounting base 1. The specific adjustment process is as follows: Loosen the locking screw 18 so that the wear-resistant anti-slip pad 19 of the locking screw 18 forms a certain gap with the outer side of the fixed mounting base 1, and release the lock on the moving bracket 3. Then the position of the moving frame 5 can be adjusted horizontally. The upper support wheel 20, the lower support wheel 24 and the side moving slide 2 are provided at the matching position between the moving bracket 3 and the side moving slide 2. The upper moving slide 16 and the moving pulley 21 are provided at the matching position between the moving frame 5 and the top surface of the fixed mounting base 1. The frictional resistance is small during the movement process and the adjustment is convenient. After adjustment, tighten the locking screw 18 so that the wear-resistant anti-slip pad 19 abuts against the outer wall of the fixed mounting base 1 and locks the position of the moving bracket 3. When the active measuring instrument for grinding is in standby or under use, the position adjustment device of the clamping device needs to be adjusted. The opening and closing top plate 7 can meet the space requirements for adjustment. During the working period, the clamping device is located outside the moving frame 5. During the non-working period, when the machine is stopped, the clamping device is adjusted and stored inside the moving frame 5. The end baffle 12 is provided with two specifications: one with a mating groove 13 and the other without a mating groove 13. The end of the moving frame 5 is shielded and protected as needed. In the stored state, the moving frame 5 can be adjusted to be flush with the fixed mounting base 1. This utility model has a reasonable structural design and is easy to install and use. By setting a fixed mounting base 1 and a movable frame 5 outside the measuring structure of the active measuring instrument, the measuring structure is protected. The movable frame 5 is equipped with a movable bracket 3 and a movable pulley 21 at the mating position with the fixed mounting base 1. The movable bracket 3 is equipped with a support wheel to facilitate the adjustment of the position of the movable frame 5. The top of the movable frame 5 is equipped with an opening and closing top plate 7, and a telescopic cover 6 is provided at the connection position between the opening and closing top plate 7 and the movable frame 5. When the position of the holding device is adjusted, the flip-opening and closing structure can meet the adjustment requirements. Although this protective device cannot completely prevent dust from entering during working use, it still has a good effect on overall dust prevention.
