[0004] However, in this patent, if this device is used in the electroplating process of brake discs, then when fixing and loading the brake discs, the contact positions between the device and the brake discs will not be able to contact the electrolyte, so there will be a problem that electroplating cannot be carried out locally. This will cause defects in the finally produced brake discs. Therefore, a loading device is needed to solve this problem. Summary of the Invention

One ends of a plurality of the elastic telescopic rods are respectively fixedly connected to the plurality of arc plates, and the other ends of the plurality of elastic telescopic rods are respectively fixedly connected to the plurality of first sliding seats and the plurality of second sliding seats.

[0010] Preferably, the driving assembly further includes a driving shaft which is rotatably connected to the main shaft, and the bottom end of the driving shaft is fixedly connected to the first rotating cylinder.

[0011] Preferably, the driving assembly further includes an oil delivery pipe and a spring. The two ends of the oil delivery pipe are respectively fixedly connected between the first rotating cylinder and the second rotating cylinder. One of the oil injection holes is communicated with the oil delivery pipe, and the spring is fixedly connected between the second rotating cylinder and the fourth rotating cylinder.

[0012] Preferably, the telescopic assembly includes first fixed cylinders. A plurality of the first fixed cylinders are fixedly connected to the main shaft. A first sliding tube is slidably connected to each of the plurality of first fixed cylinders, and a plug rod is fixedly connected to the inner wall of each of the plurality of first fixed cylinders. One ends of the plurality of plug rods are respectively slidably connected to the inside of the plurality of first sliding tubes, and the plurality of first sliding tubes are respectively fixedly connected to the plurality of arc plates.

[0013] Preferably, the telescopic assembly further includes a connecting pipe and an annular pipe.

[0015] Preferably, the detection component further includes grooves and through holes. The grooves are formed in each of the plurality of arc plates, and two through holes are formed in the interior of each of the plurality of grooves. Each of the plurality of grooves communicates with each first sliding tube and each second sliding tube through the two through holes formed therein.

[0016] Preferably, the detection component further includes power sources and wire conduits. The plurality of power sources are respectively fixedly connected to the interiors of the plurality of grooves, and wire conduits are electrically connected to each of the plurality of power sources. The plurality of wire conduits are respectively electrically connected to the plurality of first sliding seats and the plurality of second sliding seats.

[0017] Compared with the prior art, the present invention has the following remarkable advantages:

[0018] First: In the present invention, the plurality of arc plates can be extended. Since there is a circular hole at the center of the vehicle brake disc, the entire device can be passed through the circular hole on the brake disc after the arc plates are contracted. When the brake disc is located between the first clamping rod and the second clamping rod, the arc plates are then fully extended, and then the first clamping rod and the second clamping rod are brought closer to clamp the brake disc.

[0019] Second: In the present invention, when controlling the extension of the arc plates, hydraulic oil can be injected into the oil injection holes through hydraulic equipment. When the hydraulic oil enters from one of the oil injection holes, it will enter the first fixed cylinder through the annular pipe. As the hydraulic oil increases, the high pressure causes the first sliding tube to be pushed outwards, so that each arc plate is pushed outwards accordingly to complete the extension. After the first sliding tube moves outwards, the insertion rod and the first sliding tube are separated. At this time, the hydraulic oil will enter the first sliding tube, and then enter the grooves inside the arc plates, and finally enter the second sliding tube through the through holes. Since the second fixed cylinder is closed, the increase in hydraulic oil will cause the second sliding tube to move relative to the second fixed cylinder, further causing all the arc plates to be fully extended.

[0020] Third: In the present invention, when controlling the first clamping rod and the second clamping rod to clamp the brake disc, hydraulic oil can be injected into the other oil injection hole. At this time, the hydraulic oil continuously moves downwards and enters the oil delivery pipe, and then the hydraulic oil flows into the space between the second rotating cylinder and the fourth rotating cylinder. As the hydraulic oil continuously increases, the second rotating cylinder and the fourth rotating cylinder will move upwards and downwards respectively, that is, they separate from each other. At this time, the two discs will move upwards and downwards respectively, and then press against each hemisphere, and cause each first sliding seat and each second sliding seat to move upwards and downwards respectively, leaving enough space between the first clamping rod and the second clamping rod to place the brake disc. After the brake disc is placed, the hydraulic oil is sucked out. At this time, under the action of the elastic telescopic rod and the spring, the first sliding seat and the second sliding seat will reset, and the first clamping rod and the second clamping rod will also approach each other, and press against the brake disc during the approaching process, so that the brake disc is fixed.

[0021] Fourth: In the present invention, when the brake disc is being electroplated, the brake disc and the entire device are immersed in the electrolyte. To ensure that the contact points between the brake disc and the device, namely the contact points between the ends of the first clamping rod and the second clamping rod and the brake disc, are in full contact with the electrolyte, the drive shaft can be connected to an external motor to control the rotation of the drive shaft. When the drive shaft rotates, the first rotating cylinder, the second rotating cylinder, the third rotating cylinder, and the fourth rotating cylinder all rotate accordingly. At this time, the two swing rods will rotate. During the swinging process of the swing rods, they will successively press against each hemisphere. When they press against the hemisphere, the hemisphere will be pushed open. At this time, the first sliding seat and the second sliding seat will move away from each other and move away from the brake disc. However, due to the small size of the swing rods, at most only one pair of the first clamping rod and the second clamping rod can be separated from the brake disc at the same time. Therefore, as the swing rods continue to rotate, each pair of the first clamping rod and the second clamping rod will successively disengage from the brake disc, ultimately enabling the entire brake disc to come into contact with the electrolyte, avoiding the problem of local non-contact with the electrolyte, which may lead to non-electroplating and defects.

Specific implementation manner

[0034] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] The present invention provides an automatic loading device for an automobile parts processing machine tool through improvement. The technical solution of the present invention is as follows:

[0036] As Figures 1-9 shown, an automatic loading device for an automobile parts processing machine tool includes a spindle 1 and a fixing component 2. The fixing component 2 includes a plurality of arc plates 21. A first sliding seat 22 and a second sliding seat 24 are slidably connected to each of the plurality of arc plates 21. A first clamping rod 23 and a second clamping rod 25 are respectively fixedly connected to the plurality of first sliding seats 22 and the plurality of second sliding seats 24. A hemisphere 26 is fixedly connected to each of the plurality of first sliding seats 22 and the plurality of second sliding seats 24, and the hemisphere 26 is hemispherical.

[0037] A driving assembly 3 is provided on the main shaft 1. The driving assembly 3 includes a first rotating cylinder 31 which is rotatably connected to the main shaft 1. A second rotating cylinder 32 is slidably connected to the first rotating cylinder 31. A third rotating cylinder 33 is slidably connected to the second rotating cylinder 32. A fourth rotating cylinder 34 is slidably connected to the third rotating cylinder 33. A fifth rotating cylinder 35 is slidably connected to the fourth rotating cylinder 34. Swing rods 39 and discs 310 are fixedly connected to both the second rotating cylinder 32 and the fourth rotating cylinder 34. The two swing rods 39 and the two discs 310 cooperate with a plurality of hemispheres 26. The function of the swing rod 39 is that when it rotates, by contacting each hemisphere 26, the hemisphere 26 is forced to move, and at the same time, the first sliding seat 22 and the second sliding seat 24 are driven to move. The disc 310 can, when moving, simultaneously press against all the hemispheres 26, so that all the first sliding seats 22 and the second sliding seats 24 move simultaneously;

[0038] A telescopic assembly 4 is provided between the main shaft 1 and a plurality of arc plates 21. The telescopic assembly 4 includes an oil injection hole 44. Two oil injection holes 44 are opened on the main shaft 1. A detection assembly 5 is provided on a plurality of first sliding seats 22. The detection assembly 5 includes indicator lights 51. A plurality of indicator lights 51 are respectively fixedly connected to a plurality of first sliding seats 22. The indicator lights 51 can reflect the contact situation between each pair of first clamping rods 23 and second clamping rods 25 and the brake disc.

[0039] Furthermore, the fixing assembly 2 further includes fixing blocks 27 and elastic telescopic rods 28. A plurality of fixing blocks 27 are respectively fixedly connected to the tops and bottoms of a plurality of arc plates 21. One ends of a plurality of elastic telescopic rods 28 are respectively fixedly connected to a plurality of arc plates 21. The other ends of a plurality of elastic telescopic rods 28 are respectively fixedly connected to a plurality of first sliding seats 22 and a plurality of second sliding seats 24. When the first clamping rod 23 and the second clamping rod 25 clamp the brake disc together, the elastic force of the elastic telescopic rod 28 is used to clamp the brake disc tightly.

[0040] Furthermore, the driving assembly 3 further includes a driving shaft 36 which is rotatably connected to the main shaft 1. The bottom end of the driving shaft 36 is fixedly connected to the first rotating cylinder 31. The driving shaft 36 has no power source and can be used to connect to a motor and rotate.

[0041] Furthermore, the driving assembly 3 further includes an oil delivery pipe 37 and a spring 38. The two ends of the oil delivery pipe 37 are respectively fixedly connected between the first rotating cylinder 31 and the second rotating cylinder 32. One of the oil injection holes 44 is communicated with the oil delivery pipe 37. The spring 38 is fixedly connected between the second rotating cylinder 32 and the fourth rotating cylinder 34. When hydraulic oil enters between the first rotating cylinder 31 and the second rotating cylinder 32 through the oil delivery pipe 37, the high pressure can separate the first rotating cylinder 31 and the second rotating cylinder 32. The elastic force of the spring 38 can reset the first rotating cylinder 31 and the second rotating cylinder 32 after the hydraulic oil is pumped away.

[0042] Further, the telescopic assembly 4 includes a first fixed cylinder 41. A plurality of first fixed cylinders 41 are fixedly connected to the main shaft 1. A first sliding tube 42 is slidably connected to each of the plurality of first fixed cylinders 41. A plug rod 43 is fixedly connected to the inner wall of each of the plurality of first fixed cylinders 41. One end of each of the plurality of plug rods 43 is slidably connected to the inside of each of the plurality of first sliding tubes 42. Each of the plurality of first sliding tubes 42 is fixedly connected to one of the plurality of arc plates 21.

[0043] Further, the telescopic assembly 4 further includes a connecting pipe 45 and an annular pipe 46. The connecting pipe 45 is fixedly connected to the inside of the main shaft 1. The connecting pipe 45 is connected to one of the oil injection holes 44. The annular pipe 46 is also fixedly connected to the inside of the main shaft 1. The annular pipe 46 is fixedly connected to the connecting pipe 45 and is in communication with the plurality of first fixed cylinders 41. When hydraulic oil is injected from the oil injection hole 44, the hydraulic oil will enter the annular pipe 46 and then enter each of the first fixed cylinders 41.

[0044] Further, the telescopic assembly 4 further includes a second fixed cylinder 47 and a second sliding tube 48. A plurality of second fixed cylinders 47 are fixedly connected to the fifth rotating cylinder 35. A plurality of second sliding tubes 48 are respectively fixedly connected to the plurality of arc plates 21. Each of the plurality of second sliding tubes 48 is slidably connected to one of the plurality of second fixed cylinders 47. When the hydraulic oil enters from one of the oil injection holes 44, it will enter the first fixed cylinder 41 through the annular pipe 46. As the hydraulic oil increases, the high pressure causes the first sliding tube 42 to be pushed outwards, so that each of the arc plates 21 is pushed outwards accordingly to complete the extension. After the first sliding tube 42 moves outwards, the plug rod 43 and the first sliding tube 42 are separated. At this time, the hydraulic oil will enter the first sliding tube 42 and then enter the second sliding tube 48. Since the second fixed cylinder 47 is closed, the increase in hydraulic oil will cause the second sliding tube 48 to move relative to the second fixed cylinder 47, further causing all the arc plates 21 to fully unfold.

[0045] Further, the detection assembly 5 further includes a groove 54 and a through hole 55. A groove 54 is formed in each of the plurality of arc plates 21. Two through holes 55 are formed in the inside of each of the plurality of grooves 54. Each of the plurality of grooves 54 is in communication with each of the first sliding tubes 42 and each of the second sliding tubes 48 through the two through holes 55 thereon. The hydraulic oil entering the first sliding tube 42 enters the groove 54 through the through hole 55 and then enters the second sliding tube 48 through the other through hole 55.

[0046] Further, the detection assembly 5 further includes a power source 52 and a wire conduit 53. A plurality of power sources 52 are respectively fixedly connected to the inside of the plurality of grooves 54. A wire conduit 53 is electrically connected to each of the plurality of power sources 52. Each of the plurality of wire conduits 53 is electrically connected to each of the plurality of first sliding seats 22 and each of the plurality of second sliding seats 24.

[0047] The specific working method is as follows: Multiple arc plates 21 can be extended. Since there is a circular hole at the center of the vehicle brake disc, after the arc plates 21 are contracted, the entire device can be passed through the circular hole on the brake disc. When the brake disc is located between the first clamping rod 23 and the second clamping rod 25, the arc plates 21 are then fully extended, and then the first clamping rod 23 and the second clamping rod 25 are made to approach each other, thereby clamping the brake disc.

[0048] When controlling the extension of the arc plates 21, hydraulic oil can be injected into the oil injection hole 44 through hydraulic equipment. When the hydraulic oil enters from one of the oil injection holes 44, it will enter the first fixed cylinder 41 through the annular pipe 46. As the hydraulic oil increases, the high pressure pushes the first sliding pipe 42 outwards, thereby causing each arc plate 21 to be pushed outwards to complete the extension. After the first sliding pipe 42 moves outwards, the insertion rod 43 separates from the first sliding pipe 42. At this time, the hydraulic oil will enter the first sliding pipe 42, and then enter the groove 54 inside the arc plate 21, and finally enter the second sliding pipe 48 through the through hole 55. Since the second fixed cylinder 47 is closed, the increase in hydraulic oil will cause the second sliding pipe 48 to move relative to the second fixed cylinder 47, further causing all the arc plates 21 to be fully extended.

[0049] When controlling the first clamping rod 23 and the second clamping rod 25 to clamp the brake disc, hydraulic oil can be injected into the other oil injection hole 44. At this time, the hydraulic oil continuously moves downwards and enters the oil delivery pipe 37, and then the hydraulic oil flows into the space between the second rotating cylinder 32 and the fourth rotating cylinder 34. As the hydraulic oil continuously increases, the second rotating cylinder 32 and the fourth rotating cylinder 34 will move upwards and downwards respectively, that is, they separate from each other. At this time, the two discs 310 will move upwards and downwards respectively, and then press against each hemisphere 26, and cause each first sliding seat 22 and the second sliding seat 24 to move upwards and downwards respectively, leaving enough space between the first clamping rod 23 and the second clamping rod 25 to place the brake disc. After the brake disc is placed, the hydraulic oil is sucked out. Then, under the action of the elastic telescopic rod 28 and the spring 38, the first sliding seat 22 and the second sliding seat 24 will reset, and the first clamping rod 23 and the second clamping rod 25 will also approach each other and press against the brake disc during the approaching process, thereby fixing the brake disc.

[0050] When the brake disc is being electroplated, the brake disc and the entire device are immersed in the electrolyte. To ensure that the contact points between the brake disc and the device, namely the contact points between the ends of the first clamping rod 23 and the second clamping rod 25 and the brake disc, are in full contact with the electrolyte, the drive shaft 36 can be connected to an external motor to control the rotation of the drive shaft 36. When the drive shaft 36 rotates, the first rotating cylinder 31, the second rotating cylinder 32, the third rotating cylinder 33, and the fourth rotating cylinder 34 all rotate accordingly. At this time, the two swing rods 39 will rotate. During the swinging process of the swing rods 39, they will successively press against each hemisphere 26. When it presses against the hemisphere 26, the hemisphere 26 will be pushed open. At this time, the first sliding seat 22 and the second sliding seat 24 will move away from each other and move away from the brake disc. However, due to the small size of the swing rods 39, at most only one pair of the first clamping rod 23 and the second clamping rod 25 can be separated from the brake disc at the same time. Therefore, as the swing rods 39 continue to rotate, each pair of the first clamping rod 23 and the second clamping rod 25 will successively disengage from the brake disc, ultimately enabling the entire brake disc to come into contact with the electrolyte, avoiding the problem of local non-contact with the electrolyte, which may lead to non-electroplating and defects.

[0051] During the whole process, the positive and negative electrodes of the power supply 52 in each arc plate 21 are connected to the first clamping rod 23 and the second clamping rod 25 through the wire conduit 53. Since the brake disc is made of metal and has the ability to conduct electricity, when the first clamping rod 23 and the second clamping rod 25 simultaneously press against the brake disc, the circuit is conducted. The indicator light 51, as a load connected in this circuit, will be lit. Therefore, when each pair of the first clamping rod 23 and the second clamping rod 25 simultaneously presses against the brake disc, the corresponding indicator light 51 will light up to facilitate observing whether the first clamping rod 23 and the second clamping rod 25 are in contact with the brake disc.

[0052] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above technical means, but also include the technical solutions composed of equivalent replacements of the above technical features. Matters not covered in the present invention belong to the common general knowledge of those skilled in the art.
