Description

Technical Field

[0001] The invention relates to the technical field of shock absorber manufacturing equipment, and in particular to a loading and unloading mechanism of a shock absorber piston rod cutting lathe. Background Art

[0002] The shock absorber piston rod is a component that connects the shock absorber cylinder and the vehicle body or wheel, and plays a role in transmission and support. It is responsible for telescopic movement during the operation of the shock absorber, thereby achieving vibration control and absorption. During the manufacturing process, the shock absorber piston rod is usually processed on a high-precision cutting lathe.

[0003] The current shock absorber piston rod cutting lathe often relies on a three-jaw chuck to clamp the piston rod to be processed to achieve the cutting operation when working. However, the traditional three-jaw chuck clamping process usually requires manual intervention, which not only limits the improvement of production efficiency, but also leads to a relatively low degree of equipment automation. For this reason, we propose a loading and unloading mechanism for a shock absorber piston rod cutting lathe. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the shortcomings of the prior art, the present invention provides a loading and unloading mechanism for a shock absorber piston rod cutting lathe, which overcomes the shortcomings of the prior art, has a reasonable design and a compact structure, and solves the problem that the traditional three-jaw chuck clamping process usually requires manual intervention.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a loading and unloading mechanism of a shock absorber piston rod cutting lathe, comprising a lathe base and a three-jaw chuck arranged thereon, the lathe base is provided with a loading track coaxial with the three-jaw chuck, one end of the loading track is provided with a cylinder, one side is provided with an inclined loading box, and the opening side of the loading box is arranged above the side wall of the loading track;

[0008] The output end of the cylinder is connected to a push rod, which is provided with a jaws, in which a push block with an inclined front face is rotatably connected, and one side of the push block is connected to the inner wall of the jaws through a supporting spring, and the push rod is provided with a fixed block against the back of the push block;

[0009] A fixed shaft is provided on the opening side of the charging box, and a blocking plate is rotatably connected to the outer wall of the fixed shaft. The blocking plate is arranged on the opening side of the charging box, and a torsion spring is connected therebetween. A limiting rod cooperating with a push block is provided on the blocking plate.

[0010] Preferably, the push rod is connected to a push block via a push spring, and the push block is slidably arranged on a loading track.

[0016] (III) Beneficial effects

[0017] The embodiment of the present invention provides a loading and unloading mechanism for a shock absorber piston rod cutting lathe. It has the following beneficial effects:

[0018] 1. The push rod drives the push block to move so that the piston rod to be processed in the loading box slides onto the loading track, and then the push plate pushes the piston rod to be processed on the loading track into the three-jaw chuck. The three-jaw chuck clamps the piston rod to be processed, which is convenient for subsequent cutting work. There is no need to manually put the piston rod to be processed into the three-jaw chuck for clamping. This improvement significantly improves the production efficiency and the automation level of the device.

[0019] 2. After the processing is completed, the three-jaw chuck releases the clamp on the piston rod, and the piston rod falls into the net bag, and then falls into the loading chamber. The net bag reduces the shock of the piston rod to prevent the piston rod from falling directly and causing impact damage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Refer to the attached Figure 1-6 A loading and unloading mechanism of a shock absorber piston rod cutting lathe, comprising a lathe base 1 and a three-jaw chuck 2 arranged thereon, the lathe base 1 is provided with a loading track 3 coaxial with the three-jaw chuck 2, the piston rod slides into the three-jaw chuck 2 through the loading track 3, and the piston rod is clamped by the three-jaw chuck 2;

[0029] A cylinder 4 is provided at one end of the feeding track 3, and an inclined loading box 5 is provided at one side. The opening side of the loading box 5 is arranged above the side wall of the feeding track 3. The piston rod to be processed is placed in the loading box 5. During loading, the piston rod to be processed in the loading box 5 slides onto the feeding track 3. The cylinder 4 is started to push the piston rod to be processed in the feeding track 3 into the three-jaw chuck 2, and the three-jaw chuck 2 clamps the piston rod for processing.

[0030] The output end of the cylinder 4 is connected to a push rod 41, and a jaw 42 is provided on the push rod 41. A push block 44 with an inclined front face is rotatably connected in the jaw 42, and one side of the push block 44 is connected to the inner wall of the jaw 42 through a support spring 43. A fixed block 45 is provided on the push rod 41 to abut against the back of the push block 44. A fixed shaft 51 is provided on the opening side of the charging box 5. The outer wall of the fixed shaft 51 is rotatably connected to a blocking plate 52, which is arranged on the opening side of the charging box 5, and a The torsion spring 53 and the cylinder 4 are started. At this time, the push rod 41 drives the push block 44 to move. A limit rod 54 cooperating with the push block 44 is provided on the blocking plate 52. At this time, under the limit of the fixed block 45, the inclined front of the push block 44 will push the limit rod 54 to deflect upward, further making the blocking plate 52 rotate around the fixed axis 51. At this time, the gap between the blocking plate 52 and the loading box 5 can be used for the piston rod to be processed to move out, and the piston rod to be processed in the loading box 5 slides onto the loading track 3;

[0031] The push rod 41 is connected to a push block 47 through a push spring 46. The push block 47 is slidably arranged on the feeding track 3. When the cylinder 4 is started, the push rod 41 pushes the push block 47 through the push spring 46, so that the piston rod to be processed on the feeding track 3 moves into the three-jaw chuck 2 for clamping, which is convenient for subsequent cutting work.

[0032] During this process, after the push block 44 moves beyond the limit rod 54, under the action of the torsion spring 53, the blocking plate 52 is reset to prevent the excess piston rod to be processed from sliding onto the feeding track 3 and affecting the pushing work;

[0033] After the pushing is completed, the cylinder 4 drives the push rod 41 to reset. During this process, the back of the push block 44 is against one side of the limit rod 54, so that the push block 44 rotates inside the tiger's mouth 42. At this time, the blocking plate 52 will not rotate, preventing the piston rod to be processed from sliding onto the feeding track 3 when the push rod 41 is reset, thereby affecting the subsequent feeding work.

[0034] In this embodiment, a counterweight plate 55 is provided at the lower side of the blocking plate 52 to increase the weight of the bottom of the blocking plate 52, so as to facilitate the blocking plate 52 to return to its original position to block the piston rod to be processed.

[0035] In this embodiment, a plurality of track rods 6 are provided on the lathe seat 1, and a plurality of track rods 6 are used to replace the traditional single slide rail to prevent the piston rod to be processed from falling off from the inside of the three-jaw chuck 2 and falling onto the slide rail after processing, thereby causing impact damage;

[0036] A loading chamber 7 is provided on the lathe seat 1, and a net bag 8 is provided in the loading chamber 7. The processed piston rod falls into the net bag 8 of the loading chamber 7 along the gap between the plurality of track rods 6. The net bag 8 performs shock-absorbing and supporting operation on the piston rod to prevent the piston rod from falling directly and causing impact damage.

[0037] In this embodiment, the net bag 8 is Y-shaped, and an opening for unloading the piston rod is provided in the vertical part of the Y-shape, a rubber pad 9 is provided at the bottom of the opening, and a material removal port 10 is provided on the loading chamber 7. The piston rod that falls into the net bag 8 will fall downward along the vertical part of the Y-shape until it falls onto the rubber pad 9, thereby preventing the net bag 8 from storing the piston rod during continuous processing, which may cause collisions between the piston rods.

[0038] In this embodiment, the rubber pad 9 is a trapezoidal structure that is small at the top and large at the bottom. The piston rod that falls onto the rubber pad 9 will slide to both sides along the side of the rubber pad 9, thereby preventing the presence of the piston rod on the rubber pad 9 from affecting the subsequent falling of the piston rod.

[0039] In this embodiment, a baffle 31 is provided on the side of the loading track 3 facing away from the loading box 5 to prevent the piston rod to be processed in the loading box 5 from sliding onto the loading track 3 too fast and causing the piston rod to be processed to slide out of the loading track 3.

[0040] Working principle: the cylinder 4 is started, and the push rod 41 drives the push block 44 and the push block 47 to move. At this time, the push block 44 will first push the limit rod 54, causing the blocking plate 52 to deflect. At this time, the piston rod to be processed in the loading box 5 will slide onto the feeding track 3, and the push block 44 continues to move and disengages from the limit rod 54. At this time, under the action of the torsion spring 53, the blocking plate 52 is reset and blocks the subsequent piston rods to be processed to prevent excess piston rods to be processed from sliding onto the feeding track 3. The cylinder 4 continues to work. At this time, the push block 47 pushes the piston rod to be processed on the feeding track 3 into the three-jaw chuck 2, and the three-jaw chuck 2 clamps the piston rod to be processed to complete the cutting work.

[0041] After the processing is completed, the three-jaw chuck 2 releases the clamping of the piston rod, the cylinder 4 is started, and the processed piston rod is pushed again. At this time, the piston rod will fall into the net bag 8, and then fall into the loading chamber 7. The processed piston rod in the loading chamber 7 can be taken out through the feeding port 10.

[0042] Then the air cylinder 4 is controlled to drive the push rod 41 to reset. During this process, the push block 44 will deflect, which will not cause the blocking plate 52 to deflect. That is, when the push rod 41 is reset, the piston rod to be processed will not slide onto the feeding track 3, which is convenient for subsequent automatic feeding work.
