Description

Technical Field

[0001] The present invention relates to the technical field of the processing of explosion-proof fluorescent lamps for mines, and particularly to a fine grinding device for the lamp cover of an explosion-proof fluorescent lamp for mines. Background Art

[0002] The explosion-proof fluorescent lamp for mines has the characteristics of high luminous brightness, high efficiency, long service life, no stroboscopic effect, and convenient maintenance. It is used in the environments with the risk of gas or coal dust explosion in coal mines, such as the main haulage roadway, the bottom of the shaft, the motor chamber, the return airway, the fixed lighting lamp, the lighting lamp for the coal preparation plant, and can also be used in the places where explosion-proof equipment is required for lighting in industries such as metallurgy, building materials, and chemical engineering.

[0003] During the production and processing of the lamp cover of the explosion-proof fluorescent lamp for mines, when grinding it, a fine grinding device is needed. However, during the use of the existing fine grinding device, when fixing the lamp cover, it is necessary to gradually operate the fasteners to clamp and fix the lamp cover, and it cannot be operated synchronously, which makes the operation rather inconvenient. At the same time, when grinding the lamp cover, most of the existing devices have only one grinder, so when the lamp cover needs to be ground, the grinding efficiency is relatively low. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems that during the use of the existing fine grinding device, when fixing the lamp cover, it is necessary to gradually operate the fasteners to clamp and fix the lamp cover, and it cannot be operated synchronously, which makes the operation rather inconvenient, and when grinding the lamp cover, most of the existing devices have only one grinder, so when the lamp cover needs to be ground, the grinding efficiency is relatively low, and to propose a fine grinding device for the lamp cover of an explosion-proof fluorescent lamp for mines.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A finishing device for grinding the lampshade of a mine flameproof fluorescent lamp, comprising a bottom plate. On one side surface of the bottom plate, a side plate is fixedly installed. On one side surface of the side plate, a sliding rod is fixedly installed. On the outer surface of the sliding rod, a slider is slidably installed. On one side surface of the slider, a connecting block is fixedly installed. On one side surface of the connecting block, a first ejector rod is fixedly installed. On one side surface of the side plate, a threaded rod is rotatably installed. On one side surface of the side plate, a first motor is fixedly installed. On the outer surface of the threaded rod, a transmission gear is fixedly installed. On the outer surface of the sliding rod, a fixed block is fixedly installed. On one side surface of the fixed block, a second ejector rod is fixedly installed. On one side surface of the fixed block, a placement plate is fixedly installed. On one side surface of the bottom plate, a first limiting rod is fixedly installed. On the outer surface of the first limiting rod, a ring plate is slidably installed. On one side surface of the ring plate, a first limiting groove is opened. On one side surface of the ring plate, a ring gear is fixedly installed. On one side surface of the bottom plate, a column is fixedly installed. At the upper end of the column, a top plate is fixedly installed. On one side surface of the top plate, a turntable is rotatably installed. On one side surface of the turntable, a vertical rod is slidably installed. At the lower end of the vertical rod, a bracket is fixedly installed. On one side surface of the bracket, a circular ring is fixedly installed. On the outer surface of the circular ring, a cross bar is slidably installed. At one end of the cross bar, a vertical plate is fixedly installed. On one side of the vertical plate, a spring is fixedly installed. On one side surface of the vertical plate, a grinding device is fixedly installed. At the upper end of the vertical rod, a limiting plate is fixedly installed. On one side surface of the limiting plate, a second limiting groove is opened. On one side surface of the turntable, a second motor is fixedly installed. At the output end of the second motor, a crankshaft is fixedly installed. At the other output end of the second motor, a bevel gear is fixedly installed. On one side surface of the turntable, a fixed rod is fixedly installed. At the upper end of the fixed rod, a bevel gear ring is fixedly installed.

[0007] As a preferred embodiment of the present invention, four side plates are symmetrically arranged. On a single side plate, two sliding rods are symmetrically arranged. One end of the threaded rod penetrates through the connecting block and extends to the other side of the connecting block. The threaded rod is in threaded connection with the connecting block. The output end of the first motor is fixedly installed at one end of the threaded rod. The first motor can drive the threaded rod to rotate, so that the threaded rod can drive the connecting block in threaded connection with it to slide and adjust. The sliding adjustment of the connecting block can drive the sliding adjustment of the first ejector rod.

[0008] As a preferred embodiment of the present invention, the first ejector rod and the second ejector rod are located at the same horizontal position. The corresponding ends of the first ejector rod and the second ejector rod are in a hemispherical structure. When the first ejector rod slides towards the side close to the second ejector rod, the first ejector rod and the second ejector rod can clamp and fix the lampshade, making the clamping and fixing of the lampshade simple. On one side surface of the placement plate, a placement groove is opened. The placement groove is in an arc-shaped structure for placing the lampshade.

[0009] As a preferred embodiment of the present invention, a sliding connection is formed between the first limiting rod and the first limiting groove. The ring plate forms a circumferential rotation structure through the first limiting rod, and the ring plate makes a circumferential motion around the center. Four transmission gears are provided, and all four transmission gears are in an intermeshing structure with the ring teeth, so that synchronous rotation adjustment is achieved between the screw transmission gears. The rotation adjustment of the ring teeth can drive the rotation adjustment of the four transmission gears simultaneously.

[0010] As a preferred embodiment of the present invention, the vertical rod and the turntable are relatively fixed in the circumferential direction, so that when the turntable rotates, the rotation of the turntable can drive the rotation of the vertical rod. The vertical plate and the grinder both form a sliding adjustment structure through the cross bar. One end of the spring away from the vertical plate is fixedly installed on one side surface of the ring, and the spring is sleeved on the outer surface of the cross bar, so that the spring can apply an elastic force between the ring and the vertical plate, and the spring can drive the vertical plate to always move away from the ring. A grinder is fixedly installed on one side surface of the vertical plate. Under the action of the spring, the grinder always fits on the surface of the lampshade, so that when the grinder grinds the lampshade, the grinding effect is better.

[0011] As a preferred embodiment of the present invention, the crankshaft forms a rotation adjustment structure through the second motor. One end of the crankshaft away from the second motor is slidably installed in the second limiting groove. When the second motor drives the crankshaft to rotate, one end of the crankshaft away from the second motor slides and adjusts in the second limiting groove, so that the limiting plate forms an up-and-down reciprocating sliding adjustment structure through the second motor, the vertical rod forms an up-and-down reciprocating motion structure through the second motor, the bracket forms an up-and-down reciprocating movement adjustment structure, and the grinder forms an up-and-down reciprocating movement adjustment structure. When the grinder grinds the lampshade, the grinder can repeatedly grind the upper and lower positions of the lampshade, so that the grinding effect is better and the efficiency is higher.

[0012] As a preferred embodiment of the present invention, the bevel gear forms a rotation adjustment structure through the second motor. The bevel gear meshes with the bevel gear ring. When the second motor drives the bevel gear to rotate and adjust, under the action of the bevel gear ring meshing with the bevel gear, the second motor and the turntable 19 can rotate and adjust, so that the turntable drives the vertical rod to rotate and adjust, the vertical rod drives the bracket to rotate and adjust, and the bracket drives the grinder to rotate and adjust. When the grinder grinds the lampshade, the grinder can rotate around the lampshade, so as to realize grinding of different positions of the lampshade by the grinder, so that the grinding effect is better and the grinding efficiency is higher. The turntable forms a rotation adjustment structure through the second motor.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The first motor drives the threaded rod and the transmission gear to rotate. The transmission gear drives the ring gear meshing with it to rotate, and the ring gear drives the other transmission gears to rotate, enabling synchronous rotation among the four transmission gears. The synchronous rotation of the transmission gears is the synchronous rotation of the threaded rod, which drives the connecting block and the first ejector rod to move and adjust. The four first ejector rods move synchronously. When the lampshade is placed in the placement groove, the first ejector rod and the second ejector rod can fix the lampshade, simplifying the fixation of the lampshade.

[0015] 2. The second motor drives the crankshaft to rotate. The crankshaft drives the limit plate to move up and down reciprocally, and the limit plate drives the vertical rod to slide up and down reciprocally for adjustment, enabling the grinding device to move up and down reciprocally. The second motor drives the bevel gear to rotate, and under the action of the bevel gear ring meshing with the bevel gear, the turntable can rotate. The turntable drives the vertical rod and the bracket to rotate, enabling the grinding device to rotate for adjustment. When the grinding device grinds the lampshade, it can move up and down and rotate around the lampshade simultaneously, improving the grinding efficiency of the lampshade.

[0030] Embodiment 2

[0031] Please refer to Figure 1 - Figure 5 As shown in the figure, there are four side plates 2 symmetrically arranged. Two sliding rods 3 are symmetrically arranged on a single side plate 2. One end of the threaded rod 7 penetrates through the connecting block 5 and extends to the other side of the connecting block 5.

[0032] Embodiment 3

[0033] Please refer to Figure 1 - Figure 5As shown, the vertical rod 20 is relatively fixed in the circumferential direction with respect to the turntable 19, so that when the turntable 19 rotates, the vertical rod 20 can be driven to rotate.

One end of the spring 25 away from the vertical plate 24 is fixedly installed on one side surface of the ring 22, and the spring 25 is sleeved on the outer surface of the cross bar 23, so that the spring 25 can apply an elastic force between the ring 22 and the vertical plate 24, and the spring 25 can drive the vertical plate 24 to always move away from the ring 22. A grinder 26 is fixedly installed on one side surface of the vertical plate 24. Under the action of the spring 25, the grinder 26 always fits on the surface of the lamp shade, so that when the grinder 26 grinds the lamp shade, the grinding effect is better. The crankshaft 30 forms a rotational adjustment structure through the second motor 29. One end of the crankshaft 30 away from the second motor 29 is slidably installed in the second limit groove 28, so that when the second motor 29 drives the crankshaft 30 to rotate, the crankshaft 30 can drive the limit plate 27 and the vertical rod 20 to perform vertical reciprocating sliding adjustment, so that the second motor 29 can be used to drive the grinder 26 to perform vertical reciprocating movement adjustment, so that when the grinder 26 grinds the lamp shade, the grinding effect is better and the efficiency is higher.

The threaded rod 7 drives the transmission gear 9 to rotate, and the transmission gear 9 can drive the ring gear 16 meshing with it to rotate, so that the ring plate 14 slides circumferentially on the surface of the limiting rod 13. The ring gear 16 drives other transmission gears 9 meshing with it to rotate, and the remaining transmission gears 9 drive the remaining threaded rods 7 to rotate. The rotation of the threaded rod 7 drives the connecting block 5 meshing with it to slide under the action of the slider 4, so that the connecting block 5 drives the first ejector rod 6 to slide. The first ejector rod 6 can cooperate with the second ejector rod 11 to fix the lampshade. The four first ejector rods 6 move synchronously, making it easier to fix the lampshade. After the lampshade is fixed, control the second motor 29 to drive the crankshaft 30 and the bevel gear 31 to rotate. The rotation of the crankshaft 30 drives the limiting plate 27 to slide up and down reciprocally, so that the vertical rod 20 and the bracket 21 slide up and down reciprocally, and the grinder 26 can move up and down reciprocally. Control the grinder 26 so that the grinder 26 can repeatedly grind the upper and lower parts of the lampshade. The rotation of the bevel gear 31 causes the second motor 29 as a whole to rotate under the action of the meshing bevel gear ring 33, so that the turntable 19 drives the vertical rod 20 and the bracket 21 to rotate, and the grinder 26 rotates, so that the grinder 26 can rotate around the lampshade, making the grinding efficiency of the lampshade higher. Through the arranged spring 25, the spring 25 can generate an elastic force between the vertical plate 24 and the ring 22, making the vertical plate 24 always move away from the ring 22. When the grinder 26 grinds the lampshade, the grinder 26 can always fit on the outer side of the lampshade, making the grinding effect of the lampshade better.

[0035] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly.
