Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a cylinder head flipping clamp. Background Technology

[0002] To improve the level of automated manufacturing, current automotive engine production lines are beginning to achieve unmanned automated conveying and processing by using robotic arms and transfer equipment at each processing station, thereby improving production efficiency and freeing up labor.

[0003] The cylinder head is one of the important components of an engine. On the engine cylinder head production line, a flipping fixture is needed to flip the cylinder head to facilitate the processing of different surfaces. Existing flipping fixtures (such as the engine cylinder head flipping hanger disclosed in application number 202420873022.8) are prone to over-flipping during the cylinder head flipping process. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a cylinder head flipping fixture to solve the technical problem that the existing flipping fixture is prone to over-flipping during the cylinder head flipping process.

[0005] To achieve the above technical objectives, the present invention provides a cylinder head flipping fixture, comprising:

[0006] The clamping mechanism includes two lever arms and two clamping members. The two lever arms are arranged opposite to each other and spaced apart. The two clamping members are rotatably connected to the two lever arms in a one-to-one correspondence.

[0007] A first drive mechanism, which is connected to both of the lever arms, is used to drive the two lever arms to move closer to each other or further away from each other, so that the two clamping members clamp or release the cylinder head.

[0008] The second drive mechanism, which is connected to both of the clamping members, is used to drive the two clamping members to rotate synchronously about their axis so as to flip the cylinder head.

[0009] A stop mechanism is used to limit the rotation angle of the two clamping members.

[0010] Furthermore, the two lever arms are vertically arranged, and the mutually distant ends of the two clamping members are rotatably connected to the lower ends of the two lever arms in a one-to-one correspondence.

[0011] Furthermore, the clamping member is a columnar structure, which includes an interconnected mounting part and a clamping part. The mounting part is rotatably connected to the lower end of the lever arm, and the clamping part is used to abut against or separate from the side wall of the cylinder head.

[0012] Furthermore, the diameter of the clamping part is larger than the diameter of the mounting part.

[0013] Furthermore, the clamping member also includes multiple protrusions, each of which is made of rubber and is fixed to the end face of the clamping part.

[0014] Furthermore, the first driving mechanism includes a beam arm and two first telescopic driving members. The upper ends of the two lever arms are slidably connected to the beam arm, the fixed ends of the two first telescopic driving members are connected to the beam arm, and the telescopic ends of the two first telescopic driving members are connected to the upper ends of the two lever arms one by one.

[0015] Furthermore, the lever arm includes a guide sleeve, a lever arm, and an ear seat. The guide sleeve is slidably sleeved on the beam arm. The top of the lever arm is fixedly connected to the guide sleeve. The ear seat is fixedly connected to the bottom of the lever arm. The mounting part of the clamping member is rotatably connected to the ear seat.

[0016] Furthermore, the second driving mechanism includes two connecting rods and two second telescopic driving members. One end of each of the two connecting rods is fixedly connected to the opposite ends of the two clamping members. The fixed ends of the two second telescopic driving members are hinged to the two lever arms. The telescopic ends of the two second telescopic driving members are hinged to the other ends of the two connecting rods, which are used to drive the two connecting rods to rotate synchronously upward or downward.

[0017] Furthermore, the connecting rod has an L-shaped structure, with the shorter end of the connecting rod fixedly connected to the opposite end of the clamping member, and the telescopic end of the second telescopic drive member hinged to the longer end of the connecting rod, for driving the shorter part of the connecting rod to reciprocate between a horizontal and a vertical state.

[0018] Furthermore, the stopping mechanism includes a photoelectric sensor and a photoelectric sensing plate. The photoelectric sensor is fixedly connected to the shorter part of the connecting rod and is used to emit light. The photoelectric sensing plate is fixedly connected to the lower end of the lever arm. When the shorter part of the connecting rod is in a vertical state, the photoelectric sensing plate receives the light emitted by the photoelectric sensor.

[0019] Compared with the prior art, the beneficial effects of this utility model include: In use, the external drive system moves the clamp to the cylinder head to be flipped. By operating the first drive mechanism, the first drive mechanism can drive the two levers to move closer to each other, thereby clamping the cylinder head with the two clamping parts. Then, by operating the second drive mechanism, the second drive mechanism can drive the two clamping parts to rotate synchronously around their axis, thereby flipping the cylinder head. Since the stop mechanism can limit the rotation angle of the two clamping parts, it can prevent the clamping parts from rotating excessively. When using this cylinder head flipping clamp to flip the cylinder head, it can prevent the cylinder head from flipping excessively. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] This utility model provides a cylinder head flipping fixture, the structure of which is as follows: Figure 1 - Figure 3 As shown, the device includes a clamping mechanism 100, a first driving mechanism 200, a second driving mechanism 300, and a stop mechanism 400. The clamping mechanism 100 includes two lever arms 110 and two clamping members 120. The two lever arms 110 are arranged opposite each other and spaced apart. The two clamping members 120 are arranged horizontally and coaxially, and are rotatably connected to the two lever arms 110 in a one-to-one correspondence. The first driving mechanism 200 is connected to both lever arms 110 and is used to drive the two lever arms 110 to move closer to each other or further away from each other, so that the two clamping members 120 clamp or release the cylinder head 1. The second driving mechanism 300 is connected to both clamping members 120 and is used to drive the two clamping members 120 to rotate synchronously around their axes, so that the cylinder head 1 flips over. The stop mechanism 400 is used to limit the rotation angle of the two clamping members 120.

[0028] In use, the external drive system moves the clamp to the cylinder head 1 to be flipped. By operating the first drive mechanism 200, the first drive mechanism 200 can drive the two lever arms 110 to move closer to each other, thereby clamping the cylinder head 1 with the two clamping members 120. Then, by operating the second drive mechanism 300, the second drive mechanism 300 can drive the two clamping members 120 to rotate synchronously around their axis, thereby flipping the cylinder head 1. Since the stop mechanism 400 can limit the rotation angle of the two clamping members 120, it can prevent the clamping members 120 from rotating excessively. During the process of flipping the cylinder head 1 using this cylinder head flipping clamp, the cylinder head 1 can be prevented from being flipped excessively.

[0029] As a preferred embodiment, please refer to Figure 1 The two lever arms 110 are vertically arranged, and the mutually distant ends of the two clamping members 120 are rotatably connected to the lower ends of the two lever arms 110 in a one-to-one correspondence, so that the two clamping members 120 can move from the top of the cylinder head 1 to both sides of the cylinder head 1 to achieve clamping of the cylinder head 1.

[0030] As a preferred embodiment, please refer to Figure 1 The clamping member 120 is a columnar structure, which includes an installation part 121 and a clamping part 122 connected to each other. The installation part 121 is rotatably connected to the lower end of the lever arm 110. The clamping part 122 is used to abut against or separate from the side wall of the cylinder head 1. The clamping member 120 is rotatably connected to the lever arm 110 via the installation part 121. The clamping member 120 clamps or releases the cylinder head 1 via the clamping part 122.

[0031] As a preferred embodiment, please refer to Figure 1 The diameter of the clamping part 122 is larger than the diameter of the mounting part 121, which can increase the contact area with the cylinder head 1 and improve the clamping effect.

[0032] In a preferred embodiment, the clamping member 120 further includes a plurality of protrusions, each of which is made of rubber and is fixedly disposed on the end face of the clamping part 122, which can further improve the clamping effect on the cylinder head 1.

[0033] As a preferred embodiment, please refer to Figure 1 The first drive mechanism 200 includes a beam arm 210 and two first telescopic drive members 220. The beam arm 210 is horizontally arranged. The upper ends of the two lever arms 110 are slidably connected to the beam arm 210. The fixed ends of the two first telescopic drive members 220 are connected to the beam arm 210. The telescopic ends of the two first telescopic drive members 220 are connected one-to-one with the upper ends of the two lever arms 110, thus fixing the beam arm 210 to the external drive system. The beam arm 210 can support and guide the two lever arms 110, and also support the two first telescopic drive members 220. By manipulating the two first telescopic drive members 220, the telescopic ends of the two first telescopic drive members 220 can be extended or shortened, thereby driving the two lever arms 110 to move closer to each other or further away from each other.

[0034] As a preferred embodiment, please refer to Figure 1 The two first telescopic drive members 220 are located between the two lever arms 110, thereby reducing the length of the beam arm 210 and reducing the volume of the fixture.

[0035] In a preferred embodiment, the first telescopic drive 220 is a first cylinder. Hydraulic oil can be injected into the first cylinder through an external hydraulic system, thereby causing the telescopic end of the first cylinder to extend or shorten.

[0036] As a preferred embodiment, please refer to Figure 1 The lever arm 110 includes a guide sleeve 111, a lever 112, and an ear seat 113. The guide sleeve 111 is slidably sleeved on the beam arm 210. The top of the lever 112 is fixedly connected to the guide sleeve 111. The ear seat 113 is fixedly connected to the bottom of the lever 112. The mounting part 121 of the clamping member 120 is rotatably connected to the ear seat 113. By sleeved on the beam arm 210, the upper end of the lever arm 110 can be slidably connected to the beam arm 210, which is convenient for installation. To prevent the guide sleeve 111 from slipping off the end of the beam arm 210, a detachable baffle is provided at the end of the beam arm 210.

[0037] As a preferred embodiment, please refer to Figure 2 and Figure 3The second drive mechanism 300 includes two connecting rods 310 and two second telescopic drive members 320. One end of each of the two connecting rods 310 is fixedly connected to the opposite ends of the two clamping members 120. The fixed ends of the two second telescopic drive members 320 are hinged to the two lever arms 110. The telescopic ends of the two second telescopic drive members 320 are hinged to the other ends of the two connecting rods 310. The two connecting rods 310 are used to drive the two connecting rods 310 to rotate synchronously upward or downward. By operating the two second telescopic drive members 320, the two second telescopic drive members 320 can drive the two connecting rods 310 to rotate synchronously upward or downward, thereby driving the two clamping members 120 to rotate synchronously in the forward or reverse direction, realizing the flipping action of the cylinder head 1.

[0038] In a preferred embodiment, the second telescopic drive 320 is a second cylinder. Hydraulic oil can be injected into the second cylinder through an external hydraulic system, thereby causing the telescopic end of the second cylinder to extend or shorten.

[0039] As a preferred embodiment, please refer to Figure 2 and Figure 3 The connecting rod 310 has an L-shaped structure. The shorter end of the connecting rod 310 is fixedly connected to the opposite ends of the clamping member 120. The telescopic end of the second telescopic drive member 320 is hinged to the longer end of the connecting rod 310, and is used to drive the shorter part of the connecting rod 310 to reciprocate between a horizontal and a vertical state. When this flipping fixture is used to flip the horizontally placed cylinder head 1, by manipulating the two first telescopic drive members 220, the telescopic ends of the two first telescopic drive members 220 can be shortened, thereby driving the two... The lever arms 110 move closer to each other, causing the two clamping members 120 to move closer to each other until the clamping portions 122 of the two clamping members 120 are pressed against the side wall of the cylinder head 1. Then, by manipulating the two second telescopic drive members 320, the telescopic ends of the two second telescopic drive members 320 can be extended, thereby driving the two connecting rods 310 to rotate downward synchronously until the shorter part of the connecting rod 310 is in a vertical state, thereby causing the two clamping members 120 to rotate 90° in opposite directions synchronously, realizing the 90° flipping action of the cylinder head 1.

[0040] As a preferred embodiment, please refer to Figure 2 and Figure 3The stopping mechanism 400 includes a photoelectric sensor 410 and a photoelectric sensing plate 420. The photoelectric sensor 410 is fixedly connected to the shorter portion of the connecting rod 310 and is used to emit light. The photoelectric sensing plate 420 is fixedly connected to the lower end of the lever arm 110. When the shorter portion of the connecting rod 310 is in a vertical state, the photoelectric sensing plate 420 receives the light emitted by the photoelectric sensor 410. During the downward rotation of the connecting rod 310, the photoelectric sensor 410 rotates with the rotation of the connecting rod 310. When the shorter portion of the connecting rod 310 is in a vertical state, the photoelectric sensor 410 corresponds to the photoelectric sensing plate 420. Since light travels in a straight line, the photoelectric sensing plate 420 can receive the light emitted by the photoelectric sensor 410. When the photoelectric sensing plate 420 receives the light emitted by the photoelectric sensor 410, the second telescopic drive member 320 stops extending.

[0041] In another embodiment, please refer to Figure 4 and Figure 5 The stopping mechanism 400 includes a rotating plate 430 and a stop plate 440. The rotating plate 430 is fixedly connected to the far ends of the clamping member, and the stop plate 440 is fixedly connected to the lower end of the lever arm 110. When the shorter part of the connecting rod 310 is in a vertical state, the stop plate 440 abuts against the rotating plate 430. During the downward rotation of the connecting rod 310, it will drive the clamping member 120 to rotate, and the rotating plate 430 will rotate with the rotation of the clamping member 120. When the shorter part of the connecting rod 310 is in a vertical state, the stop plate 440 abuts against the rotating plate 430, and the second telescopic drive member 320 stops extending. The stop plate 440 can restrict the continued rotation of the rotating plate 430.

[0042] To better understand this utility model, the following is combined with... Figure 1 - Figure 5 The working principle of the technical solution of this utility model will be described in detail below:

[0043] In use, the external drive system moves the clamp to the cylinder head 1 to be flipped. When flipping the horizontally placed cylinder head 1 using this flipping clamp, by manipulating the two first telescopic drive members 220, the telescopic ends of the two first telescopic drive members 220 can be shortened, thereby driving the two lever arms 110 to move closer to each other, and driving the two clamping members 120 to move closer to each other, until the clamping parts 122 of the two clamping members 120 are pressed against the side wall of the cylinder head 1. Then, by manipulating the two second telescopic drive members 320, the telescopic ends of the two second telescopic drive members 320 can be extended, thereby driving the two connecting rods 310 to rotate downward synchronously, so that the shorter part of the connecting rod 310 changes from a horizontal state to a vertical state. During the downward rotation of the connecting rod 310... The photoelectric sensor 410 rotates with the rotation of the connecting rod 310. When the shorter part of the connecting rod 310 is in a vertical state, the photoelectric sensor 410 corresponds to the photoelectric sensing plate 420. Since light travels in a straight line, the photoelectric sensing plate 420 can receive the light emitted by the photoelectric sensor 410. When the photoelectric sensing plate 420 receives the light emitted by the photoelectric sensor 410, the second telescopic drive member 320 stops extending, thereby causing the two clamping members 120 to rotate 90° in opposite directions synchronously, realizing a 90° flipping action on the cylinder head 1. This avoids excessive rotation of the clamping members 120. When using this cylinder head flipping fixture to flip the cylinder head 1, excessive flipping of the cylinder head 1 can be avoided.

[0044] The cylinder head flipping fixture provided by this utility model has the following beneficial effects:

[0045] (1) During the process of the shorter part of the connecting rod 310 changing from a horizontal state to a vertical state, the photoelectric sensor 410 will rotate with the rotation of the connecting rod 310. When the shorter part of the connecting rod 310 is in a vertical state, the photoelectric sensor 410 will correspond to the photoelectric sensor 420. Since light travels in a straight line, the photoelectric sensor 420 can receive the light emitted by the photoelectric sensor 410. When the photoelectric sensor 420 receives the light emitted by the photoelectric sensor 410, the second telescopic drive member 320 stops extending, and the extension stroke of the second telescopic drive member 320 is limited, thereby limiting the rotation angle of the clamping member 120.

[0046] (2) During the downward rotation of the connecting rod 310, the clamping member 120 will rotate, and the rotating plate 430 will rotate with the rotation of the clamping member 120. When the shorter part of the connecting rod 310 is in a vertical state, the stop plate 440 abuts against the rotating plate 430, and the second telescopic drive member 320 stops extending, thus limiting the extension stroke of the second telescopic drive member 320, thereby limiting the rotation angle of the clamping member 120.

[0047] (3) When using this cylinder head flipping fixture to flip the cylinder head 1, the cylinder head 1 can be flipped too much.

[0048] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
