Description

Technical Field

[0001] This utility model relates to the field of tooling fixtures, and in particular to a cylinder head casting flipping and transfer fixture. Background Technology

[0002] Currently, the transfer of cylinder head casting blanks involves both manual and robotic transfer. Manual transfer is difficult because cylinder heads typically weigh over 100kg. Robotic transfer, on the other hand, suffers from poor versatility when handling different models of cylinder head casting blanks, and the workpieces cannot be flipped vertically. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] This utility model provides a cylinder head casting flipping and transfer fixture, which aims to solve the problem of poor versatility in the prior art when robots handle cylinder head casting blanks of different models.

[0005] (II) Technical Solution

[0006] To solve the above problems, this utility model provides a cylinder head casting flipping and transfer fixture, which includes: a fixture frame, a fixed end pressure arm, a mounting base, a swing end pressure arm, and a drive cylinder.

[0007] The clamp frame is provided with a pair of fixed end pressure arms, a pair of mounting seats, and a pair of driving cylinders, and the fixed end pressure arms, the mounting seats, and the driving cylinders are all in one-to-one correspondence.

[0008] The mounting base is slidably mounted on the clamp frame. The driving cylinder is connected to the mounting base and is used to drive the mounting base to move. Each mounting base is hinged with a swing end pressure arm. The mounting base is used to drive the swing end pressure arm to move and limit the rotation angle of the swing end pressure arm.

[0009] Preferably, the mounting base is provided with a pair of reset holes, the hinge point of the mounting base and the swing end pressure arm is located between the pair of reset holes, a reset spring is provided in the reset hole, and the first end of the reset spring extends out of the reset hole and abuts against the swing end pressure arm.

[0010] Preferably, the reset hole is an internally threaded hole, and a pre-tightening bolt is provided in the reset hole, with one end of the pre-tightening bolt abutting against the second end of the reset spring.

[0011] Preferably, both the fixed end pressure arm and the swing end pressure arm are provided with pressure blocks at their ends, and the pressure blocks are provided with toothed surfaces for contacting the workpiece.

[0016] (III) Beneficial Effects

[0017] In this invention, each swing end pressure arm corresponds to a driving cylinder for control. When clamping the workpiece, the distance between each swing end pressure arm and the fixed end pressure arm can be adjusted individually. In addition, since both swing end pressure arms can swing at a certain angle to adapt to the shape of the workpiece, the two work together to enable the cylinder head casting flipping and transfer fixture provided in this application to clamp, transfer and flip cylinder head casting blanks of different models.

[0028] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0030] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] This utility model provides a cylinder head casting flipping and transfer fixture, which includes: a fixture frame 1, fixed end pressure arms 2, mounting seats 3, swing end pressure arms 4, and drive cylinders 5. The fixture frame 1 is provided with pairs of fixed end pressure arms 2, pairs of mounting seats 3, and pairs of drive cylinders 5, each corresponding to the other. The mounting seats 3 are slidably mounted on the fixture frame 1. The drive cylinders 5 are connected to the mounting seats 3 and are used to drive the mounting seats 3 to move. Each mounting seat 3 is hinged with a swing end pressure arm 4. The mounting seat 3 drives the swing end pressure arm 4 to move and limits the rotation angle of the swing end pressure arm 4. After the swing end pressure arm 4 rotates a certain angle on the mounting seat 3, it can abut against the mounting seat 3, thereby achieving the limitation of the rotation angle of the swing end pressure arm 4 by the mounting seat 3.

[0033] In the technical solution of this utility model, two fixed-end pressure arms 2 and two swing-end pressure arms 4 are provided on the clamp frame 1. The mounting base 3 drives the swing-end pressure arms 4 to move towards or away from the fixed-end pressure arms 2 to clamp or release the workpiece. In this application, each swing-end pressure arm 4 corresponds to a driving cylinder 5 for control. When clamping the workpiece, the distance between each swing-end pressure arm 4 and the fixed-end pressure arm 2 can be adjusted individually. In addition, since both swing-end pressure arms 4 can swing at a certain angle to adapt to the shape of the workpiece, the two work together to enable the cylinder head casting flipping and transfer fixture provided in this application to clamp, transfer and flip cylinder head casting blanks of different models. In the preferred embodiment, the rotation angle of the swing-end pressure arm 4 is ±3°.

[0034] Furthermore, the mounting base 3 is provided with a pair of reset holes 31. The hinge point between the mounting base 3 and the swing end pressure arm 4 is located between the pair of reset holes 31. A reset spring 32 is provided inside the reset hole 31, and the first end of the reset spring 32 extends out of the reset hole 31 and abuts against the swing end pressure arm 4. In this design, two reset springs 32 are provided on the mounting base 3 to abut against the swing end pressure arm 4. When the swing end pressure arm 4 is not abutting against the workpiece, the swing end pressure arm 4 can return to a horizontal state under the action of the reset springs 32, which facilitates the next clamping of the workpiece.

[0035] Furthermore, the reset hole 31 is an internally threaded hole, and a preload bolt 33 is installed inside the reset hole 31. One end of the preload bolt 33 abuts against the second end of the reset spring 32. By turning the preload bolt 33, the position of the preload bolt 33 in the reset hole 31 is adjusted, thereby adjusting the initial preload of the reset spring 32.

[0036] In a preferred embodiment, both the fixed end pressure arm 2 and the swing end pressure arm 4 are provided with pressure blocks 6 at their ends. The pressure blocks 6 are provided with toothed surfaces for contacting the workpiece. The toothed surfaces refer to the array of multiple protrusions on the surface of the pressure block 6 that contacts the workpiece, which increases friction and makes the clamping more secure.

[0037] In addition, the fixture frame 1 is provided with multiple pairs of guide rails 11, and one mounting base 3 corresponds to a pair of guide rails 11. The mounting base 3 is slidably mounted on a pair of guide rails 11.

[0038] Finally, a flange 12 is provided on the fixture frame 1, which is used for connection with the robot. The flange 12 is provided with a through hole for connection with the robot.

[0039] It should be understood that the above description of the specific embodiments of this utility model is only for illustrating the technical route and features of this utility model, and its purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. However, this utility model is not limited to the specific embodiments described above. All changes or modifications made within the scope of the claims of this utility model should be covered by the protection scope of this utility model.
