Description

Technical Field

[0001] The present invention relates to the technical field of processing equipment, and more specifically, to a clamping device. In addition, the present invention also relates to a processing method suitable for the clamping device. Background Art

[0002] In order to improve the processing efficiency of diesel engine cylinder heads, large gantry milling machines are generally used in the process of milling the upper and lower surfaces of the cylinder heads. 3-10 cylinder heads can be clamped at one time. It is found in practice that the flatness of the upper and lower surfaces of the cylinder heads after milling is generally 0.15-0.25mm, and the parallelism is generally 0.10-0.22mm, which are often seriously out of tolerance, and it is also very likely to have a defect of 0.05-0.15mm cutting marks. All subsequent processes such as processing guide holes and valve seat holes are often carried out based on the upper and lower surfaces of the cylinder head. The deviation of this reference is large, which is likely to cause difficulties in cylinder assembly, low diesel engine performance and operating stability, poor sealing effect, and problems such as oil leakage and air leakage. When the upper and lower surfaces of the cylinder head are seriously out of tolerance, it will directly affect the service life of the diesel engine.

[0003] After testing, it was found that when the gantry milling machine is milling the upper and lower planes of the cylinder head, when milling the upper and lower planes of multiple cylinder heads at the same time, it is difficult for the clamping tooling of the gantry milling machine to clamp the fastening points of several cylinder heads at the same time, and some positions will be suspended in the air. It is also difficult to maintain the clamping force of several cylinder heads consistent. In the process of downward extrusion of the milling cutter disc, the position of the suspended cylinder head will inevitably change.

[0055] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0056] The core of the present invention is to provide a clamping device, which can provide a high stability for a diesel engine when clamping a plurality of cylinder heads. Another core of the present invention is to provide a processing method suitable for the clamping device.

[0057] Please refer to Figure 1 The present invention provides a clamping device, including a plurality of connecting members 1, a plurality of mounting members 3, a plurality of positioning rods 4 and two supporting members 2. The connecting member 1 has at least two first plug-in holes 121; the supporting member 2 has a plurality of second plug-in holes 21, and the two supporting members 2 are used to be arranged on the milling machine worktable opposite to each other along the first direction; the first end of the mounting member 3 has a first limiting portion 31 for preventing slipping and can be slidably arranged inside the T-slot of the milling machine worktable, and the second end is used to install the corresponding connecting member 1, and the plurality of mounting members 3 are used to be arranged sequentially and spaced between the two supporting members 2 along the first direction; at least part of the positioning rod 4 can be slidably inserted or pulled out of the second plug-in hole 21 of the corresponding supporting member 2, the first plug-in hole 121 of the corresponding connecting member 1 and the corresponding plug hole of the corresponding cylinder head 6 along the first direction, and the remaining part of the positioning rod 4 can be slidably inserted or pulled out of the first plug-in hole 121 of the corresponding connecting member 1 and the corresponding plug holes of the two cylinder heads 6 along the first direction.

[0058] like Figure 1 As shown, the connecting member 1 can adopt a rectangular seat or a tic-tac-toe frame structure, and a first plug-in hole 121 is provided on the connecting member 1, which passes through the connecting member 1 along its own thickness direction and has a rectangular or circular cross-sectional shape; furthermore, the supporting member 2 can adopt a seat or a rod or a plate, and a second plug-in hole 21 is provided on the supporting member 2, which passes through the connecting member 1 along its own thickness direction and has a rectangular or circular cross-sectional shape.

[0059] Correspondingly, the lower end of the mounting member 3 has a rectangular or trapezoidal boss so that it can be inserted into the T-slot above the milling machine worktable and can be moved into place along the length direction of the T-slot, and the upper end of the mounting member 3 has a snap-on structure or a threaded structure so that the connecting member 1 can be installed on the connecting member 1. Preferably, the mounting member 3 can adopt a T-slot bolt to reduce the cost of the clamping device; the positioning rod 4 adopts a straight rod body, and at least one end is used to insert the cylinder head 6, and the number of first plug-in through holes 121 on a connecting member 1 is greater than or equal to two, so that the cylinder head 6 can be clamped by inserting a number of positioning rods 4 on adjacent connecting members 1.

[0060] When using, Figure 1 As shown, two support members 2 are arranged along the X direction and placed on the workbench of the milling machine, and the second plug-in hole 21 of one support member 2 has a common diameter with the corresponding second plug-in hole 21 of the other support member 2, and the center line of the second plug-in hole 21 is parallel to the connection direction of the two support members 2; then the lower ends of several mounting members 3 are inserted into the corresponding T-slots located between the two support members 2 in the workbench of the milling machine, and the mounting members 3 are pushed to move to the preset position along the T-slots, and several connecting members 1 are installed on the upper ends of the corresponding mounting members 3; and the cylinder head 6 is placed on the workbench of the milling machine between the two support members 2, so that the mounting members 3 and the cylinder head 6 are alternately arranged along the connection direction of the two support members 2, and the mounting members 3 are located at the two ends of the mounting members 3 and the cylinder head 6 arranged in a row along the X direction, then the two ends of the positioning rod 4 inserted on the connecting member 1 can be inserted into the adjacent cylinder head 6, or, the adjacent cylinder head 6 and the support member 2 can be inserted.

[0061] Such an arrangement can not only position a plurality of cylinder heads 6 so as to facilitate simultaneous milling of the plurality of cylinder heads 6 using a milling machine, but also prevent the cylinder heads 6 from being suspended in the air, thereby effectively avoiding the cylinder heads 6 from being offset during the machining process.

[0062] Based on the above embodiment, the connector 1 has a third plug-in through hole 111 for plugging in the second end of the mounting member 3; and also includes a fixing member 5 for being detachably mounted on the second end of the mounting member 3 to cooperate with the second limiting portion of the mounting member 3 to clamp the connector 1.

[0063] like Figure 2 , Figure 3 and Figure 7As shown, the connector 1 is provided with a third plug-in through hole extending in the vertical direction. The third plug-in through hole 111 can be a cylindrical through hole or a rectangular through hole, etc., for plugging the upper end of the mounting member 3. Correspondingly, the clamping device is equipped with a fixing member 5 for fixing to a part of the structure protruding from the upper surface of the connector 1 at the upper end of the mounting member 3, and the mounting member 3 has a second limiting portion. The second limiting portion can be a plurality of rod-shaped protrusions or annular bosses extending in a direction perpendicular to the length of the mounting member 3. When the connector 1 is sleeved on the outside of the mounting member 3, the lower end of the connector 1 is abutted by the second limiting portion, and the upper end of the connector 1 is abutted by the fixing member 5 fixed on the mounting member 3, so as to realize the clamping of the connector 1. With such a configuration, the clamping device has a simple structure and is easy to use.

[0064] It should be noted that the type of the fixing member 5 is not limited, as long as it is detachably arranged on the mounting member 3. For example, in some specific embodiments, the fixing member 5 can be a latch with an opening tendency. Accordingly, the mounting member 3 is provided with a long strip through hole, and the size of the long strip through hole along the length direction of the mounting member 3 is greater than the size along the width direction of the mounting member 3. Figure 1 In the orientation shown, the vertical dimension of the strip-shaped through hole is larger than that of the through hole in the horizontal direction. The fixing member 5 can be inserted into the long strip-shaped through hole of the mounting member 3 and has a tendency to open vertically to compress the corresponding connecting member 1.

[0065] Based on the above embodiment, part of the first plug-in holes 121 are located on one side of the third plug-in hole 111, and the remaining first plug-in holes 121 are located on the other side of the third plug-in hole 111; and the connector 1 is a centrally symmetrical structure, and the central axis of symmetry of the connector 1 passes through the midpoint of the center line of the third plug-in hole 111 and is parallel to the center line of the first plug-in hole 121.

[0066] like Figure 7 As shown in the figure, the center line extending perpendicular to the paper plane and passing through the middle point of the axis of the third plug-in through hole 111 is the symmetric center axis of the connector 1. Figure 1 The current orientation will rotate 180° around the above symmetry center axis and will be Figure 1 The connectors 1 in the shown orientation overlap. With this arrangement, the connector 1 can be rotated 180° around the above-mentioned central axis of symmetry during use, so that the first plug-in holes 121 located on both sides of the third plug-in hole 111 can be subjected to tension or pressure occasionally, so as to extend the service life of the connector 1.

[0067] Based on the above embodiment, the connector 1 includes a main body 11, a first bracket 12 and a second bracket 13; the main body 11 has a third plug-in hole 111, and the first bracket 12 and the second bracket 13 both have a first plug-in hole 121; the first bracket 12 is located on one side of the third plug-in hole 111, and the second bracket 13 is located on the other side of the third plug-in hole 111.

[0068] like Figures 7 to 9 As shown, in the connector 1, the main body 11 is used to connect and support the first bracket 12 and the second bracket 13 with a first plug-in hole 121, and is used to plug in the matching mounting member 3. The main body 11 can be a rectangular or circular column; and the first bracket 12 is connected to the left end of the main body 11, the third plug-in hole 111 is opened in the middle position of the main body 11, and the second bracket 13 is connected to the right end of the main body 11. The first bracket 12 and the second bracket 13 can adopt an arch-shaped structure or a cylindrical structure, etc. This arrangement is convenient for ensuring the anti-bending performance of the connector 1 and reducing the manufacturing cost of the connector 1.

[0069] On the basis of the above-mentioned embodiment, the fixing member 5 is a nut structure, which is sleeved on the outer side of the second end of the corresponding mounting member 3 and is threadably matched therewith.

[0070] like Figure 2 , Figure 3 and Figure 4 As shown, the fixing member 5 adopts a nut structure with a threaded hole. When in use, the fixing member 5 is sleeved on the outer side of the upper end of the mounting member 3, and the fixing member 5 is rotated to abut the upper end of the connecting member 1, so as to reduce the difficulty of installing the fixing member 5.

[0071] On the basis of the above embodiments, it also includes a support assembly, a controller, a first slide rail, a second slide rail, a third slide rail, several first positioning assemblies, second positioning assemblies and a third positioning assemblies; the first slide rail, the second slide rail and the third slide rail can be arranged on the milling machine worktable through the support assembly, and the first slide rail, the second slide rail, the third slide rail, the first positioning assembly, the second positioning assembly and the third positioning assembly are all connected with the controller signal; the tail ends of several first positioning assemblies are installed on the corresponding sliders of the first slide rail, and the free ends of several first positioning assemblies are used to connect and position the corresponding support members 2, cylinder heads 6 and mounting members 3; the tail end of the second positioning assembly is installed on the slider of the second slide rail, and the free end of the second positioning assembly is used to install the fixing member 5; the tail end of the third positioning assembly is installed on the slider of the third slide rail, and the free end of the third positioning assembly is used to take the positioning rod 4 and insert it in a preset position.

[0072] The first slide rail, the second slide rail and the third slide rail all include guide rails and sliders, and the guide rails are parallel to each other. The guide rails are arranged on the milling machine worktable through the support assembly. For example, the bottom of the support assembly has the above-mentioned first limiting portion 31, and the sliders can slide along the corresponding guide rails.

[0073] refer to Figure 1 The orientation shown does not limit the arrangement of the first slide rail, the second slide rail and the third slide rail. For example, in some specific embodiments, the first slide rail is located at the top of the support member 2, the second slide rail is located on the back side of the support member 2, and the third slide rail is located on the front side of the support member 2, etc.; it should also be noted that the type of support assembly is not limited as long as the installation requirements are met. For example, in some specific embodiments, the support assembly includes a plurality of support legs, and the two ends of the guide rails are connected to the top ends of the corresponding support legs, or, in other specific embodiments, the support assembly includes at least two groups of frames, one end of the plurality of guide rails is connected to one group of frames, and the other end is connected to another group of frames, etc.

[0074] In coordination, a plurality of first positioning components are arranged on the corresponding sliders of the first slide rail, referring to Figure 1 In the orientation shown, when the support members 2 and the cylinder head 6 need to be placed sequentially from left to right, a number of first positioning assemblies arranged from left to right sequentially clamp a support member 2, a cylinder head 6, another cylinder head 6, another cylinder head 6, ..., another support member 2, and arrange the above-mentioned clamped structures sequentially along the X direction, that is, a support member 2, a cylinder head 6, another cylinder head 6, another cylinder head 6, ..., another support member 2 are arranged sequentially from left to right on the milling machine workbench.

[0075] Furthermore, the second positioning component is arranged on the slider of the second slide rail, so that the fixing member 5 can be taken through the second positioning component and the fixing member 5 can be installed on the upper end of the corresponding installation member 3; similarly, the third positioning component is arranged on the slider of the third slide rail, so that the positioning rod 4 can be taken through the third positioning component and inserted into the preset position.

[0076] Secondly, the first slide rail, the second slide rail, the third slide rail, the first positioning assembly, the second positioning assembly and the third positioning assembly are all connected to the controller signal to control the operation of the first slide rail, the second slide rail, the third slide rail, the first positioning assembly, the second positioning assembly and the third positioning assembly through the controller, for example, to control the moving direction and moving distance of the slide rail in the slide rail, or to control the positioning assembly to grasp, release, install corresponding components, etc. With such a setting, the clamping device has a high degree of automation, which is beneficial to reduce the labor intensity of the operator.

[0077] It should be noted that there is no limitation on the types of the first positioning assembly, the second positioning assembly and the third positioning assembly, as long as the above functions can be achieved. For example, a robotic arm with a mechanical gripper at the free end may be used, or a telescopic arm with a vacuum suction cup at the free end may be used.

[0078] On the basis of the above-mentioned embodiment, a plurality of second plug-in through holes 21 may extend with the same diameter as the corresponding first plug-in through holes 121 of the upright connector 1, so as to fix the upright cylinder head 6 with the first processed surface facing the top through the positioning rod 4; and a plurality of second plug-in through holes 21 may extend with the same diameter as the corresponding first plug-in through holes 121 of the inverted connector 1, so as to fix the inverted cylinder head 6 with the second processed surface facing the top through the positioning rod 4, and the first processed surface and the second processed surface are arranged opposite to each other.

[0079] like Figure 1 As shown, among the several cylinder heads 6 arranged along the X direction, the other ends of the positioning rods 4 inserted in the two end cylinder heads 6 are suspended in the air, and the clamping device is provided with a support member 2 for inserting the other suspended end of the positioning rod 4 to ensure the clamping performance of the several cylinder heads 6.

[0080] For example, in order to insert the leftmost positioning rod 4 from left to right into the plug hole of the leftmost cylinder head 6, a second plugging through hole 21 extending along the X direction is opened on the support member 2, and when the first processing surface of the cylinder head 6 needs to be processed, as shown in FIG. Figure 2 As shown, the cylinder head 6 is placed upright so that the first processing surface faces upward, the connecting member 1 is placed upright, and the positioning rod 4 is inserted into the cylinder head 6. Figure 5 and Figure 6 The second plugging through holes 21 located at the lower left and upper right of the support member 2 are then inserted through the corresponding first plugging through holes 121 of the connector 1 and the corresponding plug holes of the cylinder head 6 in sequence; conversely, when the second processing surface of the cylinder head 6 needs to be processed, as shown in FIG. Figure 3 As shown, the cylinder head 6 is inverted so that the second processing surface faces upward, the connecting member 1 is inverted, and the positioning rod 4 is inserted as shown in FIG. Figure 5 and Figure 6 The second plugging through holes 21 located at the upper left and lower right of the support member 2 are shown, and then the corresponding first plugging through holes 121 of the connector 1 and the corresponding plug holes of the cylinder head 6 are sequentially passed through.

[0081] It should be noted that the number and arrangement of the second plug-in holes 21 are not limited, as long as the above functions can be achieved. For example, in some specific embodiments, Figure 5As shown, the support member 2 is provided with two groups of second plug-in through holes 21 arranged in parallel in the vertical direction, or, in other specific embodiments, the number of the first plug-in through holes 121 is two, the number of the second plug-in through holes 21 is three, and the three second plug-in through holes 21 are arranged in a triangle, wherein two second plug-in through holes 21 are arranged vertically, and the remaining second plug-in through hole 21 is located at a middle height position of the side surfaces of the other two second plug-in through holes 21, as shown in FIG. Figure 7 As shown, two first plug-in holes 121 arranged in the transverse direction are provided on the connector 1, and in coordination, when the connector 1 is placed upright or inverted, a second plug-in hole 21 on the left side is used, and when the connector 1 is placed upright, a second plug-in hole 21 on the upper right side is used, and when the connector 1 is inverted, a second plug-in hole 21 on the lower right side is used.

[0082] On the basis of the above-mentioned embodiment, the positioning rod 4 is a cylindrical rod, and the second plug-in through hole 21 and the first plug-in through hole 121 are both cylindrical through holes. Such an arrangement is beneficial to improving the positioning accuracy of the cylinder head 6.

[0083] In addition to the above-mentioned clamping device, the present invention also provides a processing method for the clamping device disclosed in the above-mentioned embodiment, and the processing method comprises the following steps:

[0084] Step S1: marking the cylinder head 6 to mark the first and second machining surfaces to be machined; it is understandable that marking the surface of the cylinder head 6 to be machined by marking the surface to be machined is used to prepare for subsequent machining to align the high-speed position of the cylinder head 6 so as to ensure machining accuracy.
