Description

Technical Field

[0001] The utility model belongs to the technical field of grasping, and particularly relates to a clamping device for grasping a cylinder head. Background Art

[0002] In modern industrial production, as an important component for sealing a cylinder, the cylinder head has a wide variety of types. Especially, non-standard cylinder heads play a crucial role in specific application scenarios. However, currently, there are many challenges in the grasping and handling operations of non-standard cylinder heads. On the one hand, non-standard cylinder heads usually have unique dimensions, shapes, and weights, which makes it difficult for traditional general grasping devices to be applicable. Most of the existing grasping devices are designed for standard-sized cylinder heads. For non-standard cylinder heads, the shape and size of their grasping parts may not match well with the existing devices, resulting in unstable grasping or inability to grasp. For example, some non-standard cylinder heads may have complex structures and irregular edges, as Figure 6 and Figure 7 shown, which is a side view of a non-standard cylinder head. The jaws or adsorption mechanisms of traditional grasping devices are difficult to firmly grasp these cylinder heads, and problems such as slipping and damage are likely to occur during the handling process, seriously affecting production efficiency and product quality. On the other hand, with the increasing diversification and personalized needs of industrial production, the use of non-standard cylinder heads is becoming more and more widespread. Currently, enterprises usually adopt manual handling or temporary and unreliable grasping methods, which not only increase labor costs but also pose significant safety risks. Workers may get injured when handling non-standard cylinder heads due to their large weight or irregular shape. At the same time, the low efficiency of manual operation is difficult to meet the requirements of rapid production in modern industry. In summary, in order to meet the requirements of efficient, high-quality, and safe grasping of non-standard cylinder heads in industrial production, it is particularly urgent to develop a special device for grasping non-standard cylinder heads.

Detailed Embodiment

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] As shown in the figure: A clamping device for grasping a cylinder head, comprising a frame; a fixed clamping plate 4 and a sliding clamping plate 7; the fixed clamping plate 4 is vertically and fixedly connected to one end of the frame, and four right-angle blocks 5 with right-angle notches that can cooperate with each other are fixedly installed inside the fixed clamping plate 4. These four right-angle blocks 5 can cooperate with each other to achieve clamping and fixing of the linear edge part on one side of the target grasping object, the cylinder head 14. The cylinder head 14 with a linear edge side is as Figure 6 shown, and it is clamped and fixed. The sliding clamping plate 7 is vertically and fixedly connected to the bottom of the sliding groove 8. The sliding groove 8 is slidably connected to the slider 9. The top of the slider 9 is fixedly connected to the bottom of the frame, at the end opposite to the fixed clamping plate 4. When the device works, the sliding clamping plate 7 can move towards or away from the fixed clamping plate 4. Two right-angle blocks 5 with upward-facing right-angle notches and two cylindrical blocks 11 are fixedly installed inside the sliding clamping plate 7 for clamping and fixing the side of the cylinder head 14 with irregular holes. The side of the cylinder head 14 with irregular holes is as Figure 7 shown.

[0026] The clamping device for grasping the cylinder head further includes a sensor 6 installed on the side of the frame, specifically a proximity switch. In this example, it is mainly used for position detection and control of electrical appliances. When the cylinder head 14 approaches the sensing surface of the sensor 6 to reach the operating distance, the switch can be actuated without mechanical contact and without applying any pressure, thereby driving the clamping device to start working. This is prior art and will not be elaborated further.

[0027] A fixing plate 12 is fixedly installed outside the sliding clamping plate 7; a fixing plate 12 is also installed outside the fixed clamping plate 4, which increases the firmness of the clamping plate.

[0028] The frame includes a top seat 1, a connecting plate 2, and a base 3; the top seat 1 is installed on the robot arm, a cylinder 10 is fixedly installed on the base 3, and a notch is provided in the middle position of the end of the base connected to the slider 9. The top seat 1 and the base 3 are connected by two connecting plates 2.

[0029] The cylinder 10 is connected to the sliding clamping plate 7 through a connecting block 13; in this example, the model of the cylinder 10 is CDLQA63‌CDLQA63, which is a thin-type locking cylinder and is applied to occasions that require precise control and locking‌; this cylinder has the characteristics of single rod double action, can work under low pressure, and has high locking performance‌; the connecting block 13 is placed in the notch of the base 3, with a round hole provided inside one end, connected to the output shaft of the cylinder, and a card slot provided at the bottom of the other end, fixedly connected to the middle position on the upper side of the sliding clamping plate 7. With this setting, when power is given to the cylinder 10, the cylinder 10 will drive the sliding clamping plate 7 to move along the output shaft direction of the cylinder 10.

[0030] Four right-angle blocks 5 are arranged inside the fixed clamping plate 4, two of which are located on the lower side of the fixed clamping plate 4 with their notches facing upward, and the other two are located on the upper side of the fixed clamping plate 4 with their notches facing downward. The connecting line of the central points of the connecting surfaces of these four right-angle blocks 5 is a rectangle. This setting method is conducive to the blocks cooperating with each other to firmly and tightly clamp the side of the cylinder head 14 with a straight edge.

[0031] Two right-angle blocks 5 and two cylindrical blocks 11 are fixedly installed inside the sliding clamping plate 7. The right-angle blocks 5 are above the cylindrical blocks 11 and their notches face upward. The connecting line of the central points of the connecting surfaces of the two right-angle blocks 5 and the two cylindrical blocks 11 is a rectangle with the length of the lower base greater than that of the upper base. This setting method is conducive to the blocks cooperating with each other to firmly and tightly clamp the side of the cylinder head 14 with irregular holes.

[0032] A block inner plane 501 and a block inner inclined plane 502 are arranged inside the right-angle block 5. The right angle formed by the block inner plane 501 and another plane inside the right-angle block 5 is convenient for the block to lift and fix the cylinder head. When the device is working, the block inner inclined plane 502 contacts the cylinder head 14 prior to the block inner plane 501. This setting improves the flexible applicability of the device, can better ensure the product quality, and will not damage because the product directly contacts the edge of the right-angle block; a hole is arranged inside the surface of the right-angle block 5 for connecting with the clamping plate.

[0033] The cylindrical block 11 includes a cylindrical block base 1101, a cylinder 1102, and a frustum 1103. A hole is arranged inside the cylindrical block base 1101 and it has a cylindrical structure. A chamfer is arranged on its upper edge. The cylinder 1102 has a cylindrical structure and mainly functions to lift the cylinder head 14. The frustum 1103 has a cylindrical structure with a chamfer. In this setting method, when the device is working, since the frustum 1103 is arranged at the uppermost side of the extension line of the central axis of the cylindrical block 11, the product first contacts the frustum 1103 with a chamfered inclined plane, avoiding direct contact with the cylinder 1102 with edges, improving the flexible applicability of the device, and can better ensure the product quality, and will not be damaged by friction because the product directly contacts the edge of the edge; in addition, as Figure 5 shown, cylindrical blocks 11 with appropriate sizes can be selected according to the depth and size of the holes of the cylinder head 14.

[0034] When using this device, the top seat 1 is connected to the robot arm. With the cooperation of the sensor 6, the robot arm moves the device to the corresponding position of the cylinder head 14. At this time, the fixed clamping plate 4 is on the side of the cylinder head 14 with a straight edge, as Figure 8As shown in the figure, the two right-angle blocks 5 with upward openings on the lower side of the fixed clamping plate 4 support the straight edge on the lower side of the cylinder head 14, and the two right-angle blocks 5 with downward openings on the upper side of the fixed clamping plate 4 clamp the straight edge on the upper side of the cylinder head 14. The distance from the straight edge on the upper side of the cylinder head to the straight edge on the lower side of the cylinder head is equal to the longitudinal distance of the right-angle blocks provided on the fixed clamping plate 4. The sliding clamping plate 7 is on the side of the cylinder with irregular holes, and the cylinder 10 outputs power to drive the sliding clamping plate 7 to move towards the fixed clamping plate 4; as Figure 7 shown in the figure, the two right-angle blocks 5 with upward openings on the upper side of the sliding clamping plate 7 are correspondingly inserted into the first holes 1401 to support the upper edge of the first holes 1401, and the two cylindrical blocks 11 on the lower side are correspondingly inserted into the second holes 1402, thus completing the clamping and grasping of the cylinder head 14. The cooperation of the above components for grasping has the advantages of safety, high efficiency and reliability.

[0035] This clamping device for grasping the cylinder head makes full use of the shape and internal holes of the cylinder head 14, and designs a reasonable grasping structure to grasp and transport it. During the actual operation process, the positions and sizes of the right-angle blocks 5 and the cylindrical blocks 14 can be adjusted according to the hole positions and edge positions of the non-standard cylinder head 14 to make them correspond to each other, so as to achieve the purpose of clamping the non-standard cylinder head 14, thereby realizing grasping and transportation and improving the applicability of the device.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
