Technical Field

[0001] This utility model relates to the technical field of steering knuckle processing equipment, specifically a clamping head structure for automatic loading and unloading of steering knuckles. Background Technology

[0002] In the automated machining process of steering knuckles, the clamping head needs to efficiently clamp the upper end seat or external connector of the steering knuckle, thereby improving the efficiency of loading and unloading steering knuckles.

[0003] Currently, most common clamps use hydraulic or pneumatic direct drive to extend and retract the gripper radially, which has problems such as complex structure, large space occupation, and slow response, thus affecting the loading and unloading cycle and efficiency of the steering knuckle.

[0004] To address this, a clamping head structure for automatic loading and unloading of steering knuckles is proposed, namely, a specialized clamping device that is compact, secure, and runs smoothly, in order to improve the loading and unloading efficiency and reliability of automated steering knuckle production lines. Summary of the Invention

[0005] The purpose of this invention is to provide a clamping head structure for automatic loading and unloading of steering knuckles, so as to solve the problems of low loading and unloading efficiency of existing steering knuckle clamping heads, such as complex structure, large space occupation, and slow response, as mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamp head structure for automatic loading and unloading of steering knuckles, the steering knuckle including an end seat and an inner connector, the inner connector being used to connect to an outer connector, including a clamp top plate, a central rod fixedly connected to the bottom surface of the clamp top plate, the central rod being fixedly connected to several short arc rods through several connecting radial rods, short shafts fixedly connected between the short arc rods, and a stop rod rotatably connected to the short shafts;

[0007] The clamp top plate is slidably connected to a top rod at the center rod, and the bottom end of the top rod is fixedly connected to a frustoconical shell;

[0008] The clamp top plate is provided with a telescopic component, which is connected to the top rod to control the top rod to slide on the clamp top plate;

[0009] Several of the aforementioned abutments are located inside the frustoconical housing.

[0010] Preferably, the telescopic assembly includes a cylinder, which is mounted on the top plate of the clamp, and the movable end of the cylinder is fixedly connected to the top end of the top rod via a connecting crossbar.

[0011] Preferably, the top surface of the clamp top plate has several fixing holes on one side for fixing the clamp top plate.

[0012] Preferably, a sliding opening is provided at the center of the top surface of the clamp top plate, and the top rod is slidably connected at the sliding opening on the clamp top plate.

[0013] Preferably, several connecting rods are arranged at equal intervals around the central axis of the central rod.

[0014] Preferably, a plurality of the short arc rods are arranged at equal intervals around the central axis of the central rod, and the common center of the plurality of short arc rods is located on the central axis of the central rod.

[0015] Preferably, the short axis is cylindrical.

[0016] Preferably, a rubber block is provided at the bottom end of the abutment rod.

[0017] Preferably, a roller is rotatably connected to the outer side of the top end of the abutment.

[0018] Preferably, the rubber block is used to abut against the inner wall of the end seat or the outer connector, and the roller is rolled on the inner wall of the frustoconical housing.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This clamp head structure, through the arrangement and cooperation of the push rod, the frustum-shaped housing and the telescopic component, utilizes the up and down movement of the frustum-shaped housing to drive the bottom end of the push rod to expand outward, thereby achieving tight clamping against the inner wall of the upper end seat or outer joint of the steering knuckle, thus making the loading and unloading of the steering knuckle smoother and more efficient. The structure is simple, highly automated, and suitable for widespread application in the loading and unloading of steering knuckles.

[0021] 2. The fixture head structure utilizes rubber blocks and rollers to increase the friction between the bottom end of the push rod and the inner wall of the end seat or outer connector. This makes the push rod more secure against the end seat or outer connector, ensuring smooth loading and unloading of the steering knuckle. Meanwhile, the rollers reduce the resistance between the push rod and the frustoconical housing, making the fixture head structure run more smoothly and improving the efficiency of clamping the end seat or outer connector.

[0031] Reference Figure 1-4 As shown, this utility model provides a technical solution for a clamping head structure for automatic loading and unloading of steering knuckles:

[0032] A clamp head structure for automatic loading and unloading of steering knuckles is provided. The steering knuckle 1 includes an end seat 11 and an inner connector 12. The inner connector 12 is used to connect to an outer connector 13. This is prior art and will not be described in detail here.

[0033] Reference Figure 1-3 As shown, the fixture head structure includes a fixture top plate 2, a central rod 3 is fixedly connected to the bottom surface of the fixture top plate 2, a number of short arc rods 33 are fixedly connected to the central rod 3 through a number of connecting diameter rods 31, a short shaft 32 is fixedly connected between the number of short arc rods 33, and a stop rod 4 is rotatably connected to the short shaft 32.

[0034] It should be noted that a push rod 61 is slidably connected to the top plate 2 of the clamp at the center rod 3, and the bottom end of the push rod 61 is fixedly connected to a frustoconical housing 6. A telescopic assembly is provided on the top plate 2, and the telescopic assembly is connected to the push rod 61 to control the sliding of the push rod 61 on the top plate 2. Several abutment rods 4 are located inside the frustoconical housing 6.

[0035] Reference Figure 3 As shown, in an optional embodiment: the telescopic assembly includes a cylinder 5, which is mounted on the top plate 2 of the fixture. The movable end of the cylinder 5 is fixedly connected to the top end of the push rod 61 via a connecting crossbar 51. When using this fixture head structure, activating the cylinder 5 causes the movable end of the cylinder 5 to move up and down, thereby driving the push rod 61 to slide up and down on the top plate 2 of the fixture.

[0036] Reference Figure 3 As shown, in an optional embodiment, a plurality of fixing holes 22 are provided on one side of the top surface of the clamp top plate 2 for fixing the clamp top plate 2. It should be noted that the plurality of fixing holes 22 are arranged in a circle and are used to fix and connect with the end of the robot arm when using this clamp head structure. It should be noted that the robot and its arm are existing technology. In its actual use, the robot can control the robot arm to move to the steering knuckle, which is existing technology and will not be described in detail here.

[0037] Reference Figure 2 As shown, in an optional embodiment: a sliding through-hole 21 is provided at the center of the top surface of the clamp top plate 2, and the push rod 61 is slidably connected at the sliding through-hole 21 on the clamp top plate 2.

[0038] Reference Figure 3 As shown, in one optional embodiment: a plurality of connecting rods 31 are arranged at equal intervals around the central axis of the central rod 3. It should be further noted that a plurality of short arc rods 33 are arranged at equal intervals around the central axis of the central rod 3, and the common center of the plurality of short arc rods 33 is located on the central axis of the central rod 3. The short axis 32 is cylindrical.

[0039] Reference Figure 3As shown, in an optional embodiment, a rubber block 41 is provided at the bottom end of the abutment rod 4. It should be further noted that the rubber block 41 increases the frictional force when the bottom end of the abutment rod 4 abuts against the inner wall of the end seat 11 or the inner wall of the outer connector 13, thereby increasing the stability of the abutment rod 4 when it abuts against the upper and lower lines of the steering knuckle 1, thus allowing for smoother loading and unloading of the steering knuckle 1. It should also be noted that the steering knuckle 1 does not include the outer connector 13 when loading, but includes the outer connector 13 when unloading. When loading the steering knuckle 1, the clamping head structure abuts against the inner wall of the end seat 11 to secure the steering knuckle 1; when unloading the steering knuckle 1, the clamping head structure abuts against the inner wall of the outer connector 13 to secure the steering knuckle 1.

[0040] Reference Figure 3 As shown, in an optional embodiment, a roller 42 is rotatably connected to the outer side of the top of the abutment 4. It should be further noted that the roller 42 allows the abutment 4 to slide more smoothly and with less resistance on the inner wall of the frustoconical housing 6, thereby improving the flexibility of the frustoconical housing 6 in controlling the movement of the abutment 4 and making the clamp head structure more efficient.

[0041] It should be noted that the rubber block 41 is used to press against the inner wall of the end seat 11 or the outer connector 13, and the roller 42 is rolled on the inner wall of the frustum-shaped housing 6.

[0042] The working principle of this fixture head structure will now be explained through its working process: (Refer to...) Figure 1-4 As shown, when this clamp head structure is in use, the clamp top plate 2 is fixed to the end of the robot arm by means of the fixing port 22 and the bolts in the prior art. When the steering knuckle 1 is loading, the end seat 11 on the steering knuckle 1 is placed facing upward. When the steering knuckle 1 is unloading, the inner connector 12 on the steering knuckle 1 is connected to the outer connector 13. At this time, the outer connector 13 is placed facing upward. The robot controls its arm to move to the end seat 11 or the outer connector 13. Several abutment rods 4 extend into the end seat 11 or the outer connector 13. At this time, only the cylinder 5 needs to be activated. The movable end of the cylinder 5 moves downward, and the push rod 61 moves downward through the connecting crossbar 51, thereby pushing the frustum-shaped housing 6 downward. Under the pressure of the inner wall of the frustum-shaped housing 6, the tops of several abutment rods 4 will come together, that is, the abutment rods 4 rotate on the short shaft 32, thereby causing the bottom ends of several abutment rods 4 to expand outward, and then press against the inner wall of the end seat 11 or the outer connector 13. At this time, the robot controls its arm to move the clamp top plate 2 to the loading position or unloading position of the steering knuckle 1. Then, the cylinder 5 is activated again, causing the movable end of the cylinder 5 to move upward, thereby releasing the bottom end of the abutment rod 4 from the inner wall of the end seat 11 or the outer connector 13, thereby completing the loading and unloading of the steering knuckle 1.

[0043] This clamp head structure, through the arrangement and cooperation of the abutment rod 4, the frustum-shaped housing 6, and the telescopic component, utilizes the up-and-down movement of the frustum-shaped housing 6 to drive the bottom end of the abutment rod 4 to expand outward, thereby achieving tight clamping against the inner wall of the upper end seat 11 or the outer connector 13 of the steering knuckle 1. This makes the loading and unloading of the steering knuckle 1 smoother and more efficient. The structure is simple, highly automated, and suitable for widespread application in the loading and unloading of the steering knuckle 1.

[0044] This clamping head structure, through the setting of rubber blocks 41, rollers 42, etc., utilizes the rubber blocks 41 to increase the friction between the bottom end of the push rod 4 and the inner wall of the end seat 11 or the outer connector 13, thereby making the push rod 4 more firmly pressed against the end seat 11 or the outer connector 13, ensuring the smooth loading and unloading of the steering knuckle 1. Meanwhile, the rollers 42 reduce the resistance between the push rod 4 and the frustoconical housing 6, thereby making the operation of this clamping head structure smoother and improving the efficiency of pressing against the end seat 11 or the outer connector 13.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
