Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a robot clamping mechanism. Background Art

[0002] The robot gripping mechanism refers to a device used to fix the processing object in the mechanical manufacturing process so that it occupies the correct position to accept construction or inspection;

[0003] However, in actual application, when clamping and processing materials, vibrations will occur during the processing, which will cause the materials to shift, etc., making it difficult to meet the needs of modern life and production. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the main purpose of the utility model is to provide a robot clamping mechanism to solve the problem in the prior art that when processing materials, vibration will be generated during the processing, which makes the locking screw very easy to loosen, thereby causing the lower pressure plate to be unable to maintain stable downward pressure on the material, thereby causing the material to shift, etc.

[0005] The technical solution of the utility model is as follows: a robot clamping mechanism comprises a base plate, the top of the base plate is rotatably connected to two moving rods, the top of the base plate and one side of the moving rod are rotatably connected to a hydraulic cylinder, the outer sides of the moving rods are sleeved with sleeves, the sleeves are slidably connected to the corresponding moving rods, the piston rods of the hydraulic cylinders are rotatably connected to the corresponding sleeves, the outer sides of the sleeves and above the hydraulic cylinders are rotatably connected to connecting rods, the tops of the moving rods are rotatably connected to pressure rods, the ends of the connecting rods away from the sleeves are rotatably connected to the corresponding pressure rods, and the sides of the two moving rods close to each other and below the sleeves are fixedly connected to an L-shaped rod.

[0006] Through the above technical scheme, by starting the hydraulic cylinder, the hydraulic cylinder pushes the sleeve, so that it can drive the moving rod to move. During the movement of the moving rod, the L-shaped rod can hold the material to fix it. When the L-shaped rod holds the material, the moving rod will not move, so that the hydraulic cylinder can push the sleeve to move upward. When the sleeve moves upward, it drives the connecting rod to make one end of the pressure rod move downward, so that the material can be pressed and kept stable. Even if vibration occurs during the processing, it will not affect the hydraulic cylinder to push the sleeve. Since the pressure rod, the moving rod and the sleeve are in a linkage relationship, the occurrence of offset when the material is produced is avoided.

[0007] As a preferred implementation, one side of the L-shaped rod is fixedly connected to a second rubber block, and the bottom of the pressure rod and one end away from the connecting rod is fixedly connected to a first rubber block.

[0008] Through the above technical solution, the second rubber block can prevent the L-shaped rod from causing damage to the material when fixing the material, and the first rubber block can also play an anti-slip role while protecting the material.

[0009] As a preferred embodiment, a spring is sleeved on the outer side of the moving rod and between the sleeve and the pressure rod.

[0010] Through the above technical solution, during the upward movement of the sleeve, since the outer side of the moving rod is sleeved with a spring, the elasticity of the spring enables the pressing rod to play a buffering role when pressing the material downward.

[0011] As a preferred embodiment, an operating platform is fixedly connected to the top of the base plate and located between the two L-shaped rods.

[0012] Through the above technical solution, by placing the material above the operating platform, the equipment can operate the material.

[0013] As a preferred implementation, fixing holes are provided at four corners of the bottom of the base plate.

[0014] Through the above technical solution, the device can be fixed inside the numerical control device through the fixing hole.

[0015] As a preferred implementation, the hydraulic cylinders are all electrically connected to an external control panel.

[0016] Through the above technical solution, the hydraulic cylinder can be controlled through an external control panel.

[0017] Compared with the prior art, the advantages and positive effects of the utility model are:

[0018] In the utility model, by starting the hydraulic cylinder, the hydraulic cylinder pushes the sleeve, so that it can drive the moving rod to move. During the movement of the moving rod, the L-shaped rod can hold the material to fix it. When the L-shaped rod holds the material, the moving rod will not move, so that the hydraulic cylinder can push the sleeve to move upward. When the sleeve moves upward, it drives the connecting rod to make one end of the pressure rod move downward, so that the material can be pressed and kept stable. Even if vibration occurs during the processing, it will not affect the hydraulic cylinder pushing the sleeve. Since the pressure rod, the moving rod and the sleeve are in a linkage relationship, the occurrence of deviation of the material when it is produced is avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example

[0028] As shown in the figure, the utility model provides a technical solution: it includes a base plate 1, the top of the base plate 1 is rotatably connected to two moving rods 2, the top of the base plate 1 and one side of the moving rod 2 are rotatably connected to the hydraulic cylinder 3, the outer side of the moving rod 2 is sleeved with a sleeve 5, the sleeve 5 is slidably connected to the corresponding moving rod 2, the piston rod of the hydraulic cylinder 3 is rotatably connected to the corresponding sleeve 5, the outer side of the sleeve 5 and the upper part of the hydraulic cylinder 3 are rotatably connected to the connecting rod 4, the top of the moving rod 2 is rotatably connected to the pressure rod 7, the end of the connecting rod 4 away from the sleeve 5 is rotatably connected to the corresponding pressure rod 7, and the side close to the two moving rods 2 and located below the sleeve 5 are fixedly connected with an L-shaped rod 9.

[0029] In this embodiment, the hydraulic cylinder 3 is started to push the sleeve 5, so that it can drive the moving rod 2 to move. During the movement of the moving rod 2, the L-shaped rod 9 can hold the material against the material, thereby fixing it. When the L-shaped rod 9 holds the material, the moving rod 2 will not move, so that the hydraulic cylinder 3 can push the sleeve 5 to move upward. When the sleeve 5 moves upward, it drives the connecting rod 4, so that one end of the pressure rod 7 can move downward, so that the material can be pressed and kept stable. Even if vibration occurs during the processing, it will not affect the hydraulic cylinder 3 from pushing the sleeve 5. Since the pressure rod 7, the moving rod 2 and the sleeve 5 are in a linkage relationship, the occurrence of material displacement when it is produced is avoided.

[0030] As shown in the figure, a second rubber block 10 is fixedly connected to one side of the L-shaped rod 9 , and a first rubber block 8 is fixedly connected to the bottom of the pressure rod 7 and one end away from the connecting rod 4 .

[0031] In this embodiment, the second rubber block 10 is used to prevent the L-shaped rod 9 from causing damage to the material when fixing the material, and the first rubber block 8 can also play an anti-slip role while protecting the material.

[0032] As shown in the figure, a spring 6 is sleeved on the outer side of the moving rod 2 and between the sleeve 5 and the pressure rod 7 .

[0033] In this embodiment, during the upward movement of the sleeve 5, since the outer side of the moving rod 2 is sleeved with a spring 6, the elasticity of the spring 6 enables the pressing rod 7 to play a buffering role when pressing the material downward.

[0034] As shown in the figure, an operating platform 11 is fixedly connected to the top of the base plate 1 and located between the two L-shaped rods 9 .

[0035] In this embodiment, by placing the material above the operating platform 11 , the device can operate the material.

[0036] As shown in the figure, fixing holes 12 are formed at four corners of the bottom of the base plate 1 .

[0037] In this embodiment, the device can be fixed inside the numerical control device through the fixing hole 12 .

[0038] As shown in the figure, the hydraulic cylinders 3 are electrically connected to the external control panel.

[0039] In this embodiment, the hydraulic cylinder 3 can be controlled through an external control panel.

[0040] Working principle:

[0041] As shown in the figure, by placing the material on the top of the operating platform 11, the hydraulic cylinder 3 is started, so that the hydraulic cylinder 3 pushes the sleeve 5, so that it can drive the moving rod 2 to move. During the movement of the moving rod 2, the L-shaped rod 9 can hold the material to fix it. When the L-shaped rod 9 holds the material, the moving rod 2 will not move, so that the hydraulic cylinder 3 can push the sleeve 5 to move upward. When the sleeve 5 moves upward, it drives the connecting rod 4, so that one end of the pressure rod 7 can move downward, so that the material can be pressed and kept stable. Even if vibration occurs during the processing, it will not affect the hydraulic cylinder 3 pushing the sleeve 5. Since the pressure rod 7, the moving rod 2 and the sleeve 5 are in a linkage relationship, the occurrence of deviation and the like when the material is produced is avoided;

[0042] During the upward movement of the sleeve 5, since the outer side of the moving rod 2 is sleeved with a spring 6, the elasticity of the spring 6 enables the pressing rod 7 to play a buffering role when pressing the material downward.

Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
