Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary device technology, and in particular to an auxiliary device for mechanical gear assembly and calibration. Background Technology
[0002] Gear meshing clearance is a key parameter to ensure smooth operation of gear transmission. Adjusting gear meshing clearance is a highly technical and meticulous task. Inappropriate clearance can lead to unstable gear transmission and even start-up jitter, which can easily accelerate gear wear and damage. Therefore, when making adjustments, multiple factors such as gear material, tooth profile, number of teeth, and load must be considered.
[0003] When assembling gears, workers need to use a wedge gauge to insert into the gap between the meshing points of two gears to detect and calibrate the gear meshing clearance. However, the wedge gauge is a single unit, and when the scale markings at its tip or another part become severely worn after prolonged use, workers can only replace the entire gauge, making it difficult to replace the damaged part separately. This can easily increase the operating costs for workers. Therefore, a mechanical gear assembly and calibration auxiliary device is needed. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary device for assembling and calibrating mechanical gears.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A mechanical gear assembly and calibration auxiliary device includes a fixing plate, a base plate fixedly connected to the bottom of one side of the fixing plate, and a measuring mechanism provided on one side of the fixing plate; The measuring mechanism includes a ruler body located on the top of the base plate. The ruler body is composed of a first measuring block and multiple second measuring blocks. The top of both the first and second measuring blocks is provided with scale markings. The first measuring block is located on the side of the base plate away from the fixed plate, and the second measuring blocks are located on the top of the base plate. The side of the base plate away from the fixed plate and the top of the base plate are provided with mating grooves. A mating block is fixedly connected to one side of the first measuring block and the bottom of the second measuring block. The mating block is slidably connected in the mating groove. The front and back of the base plate are detachably connected with baffles for covering the mating grooves.
[0006] By adopting the above technical solution and setting up a measuring mechanism, when the feeler gauge has been used for a long time and its tip or scale marks have been severely worn, the staff can replace the severely worn parts separately, thereby reducing the staff's operating costs.
[0007] Preferably, both the docking groove and the docking block have a T-shaped cross-section.
[0008] By adopting the above technical solution, when the baffle is connected to the base plate and blocks the docking groove, the docking block will not fall off from the docking groove at will, thus making it easier to ensure the stability of the connection between the first measuring block, the second measuring block and the base plate.
[0009] Preferably, two slots are formed between the fixing plate and the base plate, and a plug is fixedly connected to the side of the baffle near the base plate, the plug being inserted into the slot.
[0010] By adopting the above technical solution and setting slots and plugs, it is easy for staff to quickly disassemble and assemble the baffle, thereby facilitating the quick disassembly and assembly of the first measuring block and the second measuring block.
[0011] Preferably, a guide rod is fixedly connected to the other side of the fixing plate, and the insertion block and the fixing plate are both provided with insertion holes on the same side. A sliding sleeve is slidably fitted on the outside of the guide rod, and two insertion rods for cooperating with the insertion holes are fixedly connected to one side of the sliding sleeve.
[0012] By adopting the above technical solution, when the staff inserts the plug rod into the socket, the plug block located in the slot can be positioned so that the plug block cannot fall out of the slot, thereby ensuring the stability of the baffle and preventing the baffle from falling off at will.
[0013] Preferably, a limiting plate is fixedly connected to the other end of the guide rod away from the fixed plate, and a spring is fixedly connected to the side of the limiting plate near the guide rod, with one end of the spring fixedly connected to the other side of the sliding sleeve.
[0014] By adopting the above technical solution, when the sliding sleeve and the insert rod are pulled to move closer to the limiting plate, the spring will be compressed. When the worker releases the sliding sleeve, the compressed spring can rebound, thereby driving the sliding sleeve and the insert block to move quickly back to their original positions, improving the worker's work efficiency.
[0015] Preferably, a handle is fixedly connected to the other side of the fixing plate, and a protective cover is provided on the outside of the handle. The protective cover has anti-slip texture and is made of rubber.
[0016] By adopting the above technical solution, when staff use the device, they can hold the protective cover and handle to prevent their hands from slipping.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting up a measuring mechanism, when the feeler gauge has been used for a long time and its tip or scale marks have been severely worn, the staff can replace the severely worn parts individually, thereby reducing the staff's operating costs.
[0018] 2. By setting up insert blocks, holes, and rods, when the operator inserts the rod into the hole, the insert block located in the slot can be positioned, preventing the insert block from falling out of the slot. This helps to ensure the stability of the baffle and prevents the baffle from falling off at will. In turn, it helps to ensure the stability of the connection between the first measuring block, the second measuring block, and the base plate, and also makes it convenient for the operator to quickly install and remove the baffle.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1 , Figure 2 and Figure 3 A mechanical gear assembly calibration auxiliary device includes a fixing plate 1, a base plate 2 fixedly connected to the bottom of one side of the fixing plate 1, and a measuring mechanism 3 provided on one side of the fixing plate 1. The measuring mechanism 3 includes a ruler 31, which is located on the top of the base plate 2. The ruler 31 is composed of a first measuring block 32 and multiple second measuring blocks 33. The top of both the first measuring block 32 and the second measuring blocks 33 are provided with scale marks 37. The first measuring block 32 is located on the side of the base plate 2 away from the fixed plate 1, and the second measuring blocks 33 are located on the top of the base plate 2. The side of the base plate 2 away from the fixed plate 1 and the top are provided with mating grooves. The bottom of the first measuring block 32 and the second measuring block 33 are fixedly connected to a mating block 34, which is slidably connected in the mating groove. The front and back of the base plate 2 are detachably connected with baffles 35 for covering the mating grooves. This allows for the replacement of severely worn parts when the wedge gauge has been used for a long time and has developed severe wear, thereby reducing the cost of use.
[0023] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the cross-sections of the docking groove and the docking block 34 are both T-shaped, which helps to prevent the first measuring block 32, the second measuring block 33 and the base plate 2 from separating.
[0024] Furthermore, refer to Figure 2 and Figure 3 It can be seen that two slots 38 are formed between the fixed plate 1 and the base plate 2. The baffle 35 is fixedly connected to the side of the base plate 2 with the plug 36 inserted into the slot 38, so that the staff can quickly connect the baffle 35 and the base plate 2.
[0025] Furthermore, refer to Figure 1 It can be seen that the height of the top of the ruler 31 gradually increases from left to right, and the bottoms of the first measuring block 32, the base plate 2 and the baffle 35 are flush, which makes it easy for the staff to insert the device into the meshing of the two gears, thereby facilitating the rapid detection of the gear meshing clearance.
[0026] Furthermore, refer to Figure 3 and Figure 5 It can be seen that a guide rod 4 is fixedly connected to the other side of the fixing plate 1, and the insertion block 36 and the fixing plate 1 are both provided with insertion holes. A sliding sleeve 7 is slidably sleeved on the outside of the guide rod 4, and two insertion rods 8 are fixedly connected to one side of the sliding sleeve 7 for cooperating with the insertion holes, so as to facilitate the positioning of the insertion block 36 and the baffle 35 and prevent the baffle 35 from falling off at will.
[0027] Furthermore, refer to Figure 3 and Figure 5 It can be seen that the guide rod 4 is fixedly connected to the other end away from the fixed plate 1 by a limiting plate 5. The size of the limiting plate 5 is larger than the size of the inner side of the sliding sleeve 7, so as to prevent the sliding sleeve 7 from falling off the outside of the guide rod 4 at will.
[0028] Furthermore, refer to Figure 3 and Figure 5It can be seen that there are at least two guide rods 4, which makes it easier to ensure that the sliding sleeve 7 moves stably.
[0029] Furthermore, refer to Figure 3 and Figure 5 It can be seen that a spring 6 is fixedly connected to the side of the limiting plate 5 near the guide rod 4. One end of the spring 6 is fixedly connected to the other side of the sliding sleeve 7, which makes it easier to prevent the sliding sleeve 7 from moving at will, and thus makes it easier to prevent the insertion rod 8 from falling out of the insertion hole at will.
[0030] Furthermore, refer to Figure 3 and Figure 5 It can be seen that a handle is fixedly connected to the other side of the sliding sleeve 7, which makes it convenient for staff to move the sliding sleeve 7 by pulling the handle.
[0031] Furthermore, refer to Figure 1 and Figure 2 It can be seen that a handle is fixedly connected to the other side of the fixed plate 1. A protective cover is fitted on the outside of the handle. The protective cover has anti-slip texture and is made of rubber, which makes it easy for staff to hold.
[0032] In this utility model, when the worker assembles the gears, the worker can hold the handle and insert the device into the meshing point of the two gears, thereby determining the meshing gap of the two gears by means of the scale mark 37. When the ruler 31 or the scale mark 37 is severely worn after long-term use, the worker can pull the sliding sleeve 7 towards the direction of the limiting plate 5 and squeeze the spring 6. When the sliding sleeve 7 moves, it can drive the insertion rod 8 to move, thereby moving the insertion rod 8 out of the insertion hole and releasing the positioning of the insertion block 36. At this point, the worker can pull the baffle 35. When the baffle 35 is pulled, it can move the insert block 36, thereby moving the insert block 36 out of the slot 38 and quickly removing the baffle 35, exposing the docking groove. At this point, the worker can push the severely worn first measuring block 32 and second measuring block 33. The movement of the first measuring block 32 and second measuring block 33 can move the docking block 34, causing the docking block 34 to move out of the docking groove. Then, the new first measuring block 32 and second measuring block 33 are connected to the base plate 2 through the docking block 34, and the worker can then remove the severely worn first measuring block 32 and second measuring block 33 for individual replacement. After the first measuring block 32 and the second measuring block 33 are replaced, the staff inserts the insert block 36 into the inside of the slot 38, uses the baffle 35 to cover the docking groove to prevent the docking block 34 from falling out of the docking groove, and finally, loosens the sliding sleeve 7 so that the compressed spring 6 rebounds, driving the sliding sleeve 7 and the insert rod 8 to move away from the limit plate 5 until the insert rod 8 is inserted into the socket to position the insert block 36, and then the device can be used normally.
