Description

Technical Field

[0001] The utility model belongs to the technical field of workpiece clamping, and in particular relates to a double-station clamping device for a cylinder head. Background Art

[0002] The cylinder head is a key component of an engine. Its primary function is to seal the upper portion of the cylinder and, together with the piston top and cylinder wall, form the combustion chamber. Cylinder heads are typically made of high-quality gray cast iron or alloy cast iron, while gasoline engines for passenger cars often use aluminum alloy cylinder heads. The production process for a cylinder head primarily involves casting, machining, surface treatment, and testing. To improve production efficiency, conventional cylinder head processing typically utilizes automated assembly lines, employing conveyor rollers instead of traditional pallet transport. This improves transport efficiency, but after the cylinder head is moved to its designated location, it still requires manual handling to the designated processing station. This increases the operator's workload and poses safety risks during handling. While conventional robotic handling methods have been employed, a single robot can only handle cylinder heads for one process step, resulting in low efficiency and high costs. Utility Model Content

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.

[0043] As shown in the figure, a double-station clamping device for a cylinder head includes:

[0044] The base frame 2 has a first station mounting surface 202. Specifically, the base frame 2 also includes an end connection surface 201 perpendicular to the first station mounting surface 202. The flange 1 is connected to the end connection surface 201. The first station mounting surface 202 is mainly used to place the cylinder head in this position, clamp it in this position, and then move it to another designated position;

[0045] A positioning assembly is mounted on the first station mounting surface 202 and is configured to position the cylinder head; specifically, the positioning assembly includes: a first positioning seat 4, of which a plurality is provided. In this example, there are four first positioning seats 4, which serve as a positioning reference for the cylinder head and are mounted on the first station mounting surface 202 and are configured to contact one of the surfaces of the cylinder head to achieve a positioning effect; a second positioning seat 5, of which a plurality is provided, the upper end of which can be inserted into the process hole of the cylinder head to achieve a positioning effect, the second positioning seat 5 includes a positioning rod 501 that matches the process hole on the cylinder head, the positioning rod 501 can be inserted into the process hole, the root of the positioning rod 501 has a step portion 502, the end face of the step portion 502 contacts the surface of the cylinder head, and in this example, there are two second positioning seats 5, which are mainly used to achieve precise clamping and precise positioning of the cylinder head to improve the accuracy of subsequent machining;

[0046] There are multiple clamping assemblies. In this example, there are four clamping assemblies, which are distributed at the four corners of the surface of the first station mounting surface 202 and are configured to clamp the cylinder head after the cylinder head is positioned. Specifically, the clamping assembly includes: a mounting plate 8; a connecting rod 9, one end of which is hinged to the surface of the mounting plate 8; a first cylinder 6, which is fixedly connected to the mounting plate 8, and its telescopic rod can pass through the mounting plate 8 and extend to the outside of the mounting plate 8; a pressure block 10, an end of which is hinged to the telescopic rod of the first cylinder 6, and the middle part of which is hinged to the other end of the connecting rod 9; when the clamping assembly is in operation, the first cylinder 6 is started, and its telescopic rod extends upward, so that the upper end of the pressure block 10 can be flipped downward to press the cylinder head;

[0047] The fixing plate 15 is installed on a side away from the first station installation surface 202 and has a second station installation surface 1501 on its surface;

[0048] A first clamping seat 23, which is slidably connected to one side of the second station mounting surface 1501;

[0049] The second clamping seat 25 is slidably connected to the other side of the second station mounting surface 1501 and moves synchronously with the first clamping seat 23 in opposite directions.

[0050] The area where the second station mounting surface 1501 is located is used to clamp and position another cylinder head (different from the cylinder head set on the first station mounting surface 202 ), and the clamping and positioning components are the first clamping seat 23 and the second clamping seat 25 .

[0051] Specifically, the clamping assembly also includes: a support seat 3, one end of which is fixed on the first workstation mounting surface 202, and the other end is connected to the mounting plate 8. The support seat 3 is mainly used to support the mounting plate 8. When adjusting the pressing height of the pressure block 10, it is only necessary to grind the height of the support seat 3.

[0052] Specifically, a first sensor 7 is provided on the first station mounting surface 202. The first sensor 7 is configured to detect the position of the cylinder head. The first sensor 7 is a photoelectric switch. When the cylinder head is placed at a designated position in the area where the first station mounting surface 202 is located, the first sensor 7 can detect the position of the cylinder head, thereby performing the next clamping action.

[0053] Specifically, the second station mounting surface 1501 of the fixed plate 15 is connected with: a guide rail 16 having at least two rails, on which a slider 17 is slidably connected, and the first clamping seat 23 and the second clamping seat 25 are mounted on the slider 17 to achieve movement of the first clamping seat 23 and the second clamping seat 25 to reduce friction resistance;

[0054] The middle seat 18 has a rotating seat 19 rotatably mounted thereon; wherein, both ends of the rotating seat 19 are hinged with connecting rods 20, and the ends of the connecting rods 20 are respectively hinged to the first clamping seat 23 and the second clamping seat 25. When the rotating seat 19 rotates, the first clamping seat 23 and the second clamping seat 25 can be driven to move by the connecting rod 20. With such an arrangement, the two clamping seats can be moved together when only one of the clamping seats is driven to move, and the two clamping seats can move toward the middle direction at the same time, which can improve the stability of the clamping during the clamping of the workpiece.

[0055] Specifically, a fourth sensor 21 is installed on the second station mounting surface 1501. The fourth sensor 21 is a photoelectric switch. It is mainly used to monitor the position of the cylinder head when the cylinder head is located at the designated position in the area where the second station mounting surface 1501 is located, and then perform the next clamping action.

[0056] The lower surface of the fixed plate 15 is installed with a second sensor 12 and a third sensor 13 arranged at intervals through a bracket 14. The first clamping seat 23 has a vertical plate 22 extending downward. When the vertical plate 22 moves with the first clamping seat 23, the second sensor 12 and the third sensor 13 can monitor the moving position of the vertical plate 22. The second sensor 12 and the third sensor 13 are travel switches for controlling the maximum stroke of the vertical plate 22.

[0057] At least two hydraulic buffers 26 are also installed on the second workstation mounting surface 1501. When the second clamping seat 25 moves, specifically when it moves in the clamping direction, it can contact the hydraulic buffer 26, mainly to avoid the problem of collision between the two clamping seats and the cylinder head.

[0058] A second cylinder 11 is installed on the lower surface of the fixed plate 15. The telescopic rod of the second cylinder 11 is connected to the vertical plate 22. The second cylinder 11 serves as a driving source for the movement of the first clamping seat 23 and the second clamping seat 25. After startup, it can drive the two clamping seats to move simultaneously to complete the clamping action.

[0059] When this double-station clamping device for the cylinder head is in use, the flange 1 at the end face position is used to directly connect to the robot arm, and the robot is used to control the movement of the clamping device. In the actual production process, the cylinder head is transported to the specified position by the conveyor roller, and the robot arm can control the clamping device to move to the specified position, thereby clamping the cylinder head.

[0060] Specifically, the cylinder head in the area where the first station mounting surface 202 is located is the workpiece that needs to be clamped during the finishing process. Therefore, it is necessary to use the first positioning seat 4 and the second positioning seat 5 to jointly position the workpiece, use the pressure block 10 to accurately clamp the workpiece, and then use the robot to move the workpiece to the designated position of the machining center to achieve the effect of precise positioning and precise movement;

[0061] The cylinder head located in the area of ​​the second workstation mounting surface 1501 has a lower processing accuracy than the above-mentioned one, so it only needs to be simply clamped by the first clamping seat 23 and the second clamping seat 25. Positioning blocks 24 are provided on the facing surfaces of the first clamping seat 23 and the second clamping seat 25 for clamping to the specified position of the cylinder head, thereby realizing the clamping action of double workstations and double cylinder heads.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
