Description

Technical Field

[0001] This invention relates to the field of processing equipment technology, and more specifically, to a clamping device. Furthermore, this invention also relates to a processing method applicable to the aforementioned clamping device. Background Technology

[0002] To improve the machining efficiency of diesel engine cylinder heads, large gantry milling machines are commonly used for milling the upper and lower surfaces of the cylinder head. A single loading can accommodate 3-10 cylinder heads. However, practical experience has shown that the flatness of the milled cylinder head's upper and lower surfaces is typically 0.15-0.25mm, and the parallelism is typically 0.10-0.22mm, often exceeding tolerances significantly. Furthermore, defects such as tool marks of 0.05-0.15mm are highly likely to occur. Subsequent machining processes, such as manifold holes and valve seat holes, are often performed using the upper and lower surfaces of the cylinder head as a reference. Significant deviations in this reference can lead to difficulties in cylinder assembly, lower diesel engine performance and operational stability, poor sealing, and problems such as oil and air leaks. When the upper and lower surfaces of the cylinder head are severely out of tolerance, it directly affects the service life of the diesel engine.

[0003] Through testing, it was found that during the milling of the upper and lower planes of cylinder heads on a gantry milling machine, when milling the upper and lower planes of multiple cylinder heads simultaneously, the clamping fixture of the gantry milling machine is unable to clamp the fastening points of several cylinder heads at the same time. Some positions will be suspended in the air, and the clamping force of several cylinder heads is difficult to keep consistent. During the downward pressing process of the milling cutter, the position of the suspended cylinder head will inevitably change.

[0004] In summary, how to provide a clamping device to improve the stability of diesel engines is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] The core of this invention is to provide a clamping device that improves the stability of a diesel engine when clamping multiple cylinder heads. Another core aspect of this invention is to provide a processing method suitable for the aforementioned clamping device.

[0057] Please refer to Figure 1 This invention provides a clamping device comprising several connecting members 1, several mounting members 3, several positioning rods 4, and two support members 2. Each connecting member 1 has at least two first insertion through holes 121; each support member 2 has several second insertion through holes 21, and the two support members 2 are arranged opposite each other on a milling machine worktable along a first direction; each mounting member 3 has a first limiting portion 31 at its first end to prevent detachment and is slidably disposed inside a T-slot on the milling machine worktable, and its second end is used to mount a corresponding connecting member 1; the several mounting members 3 are arranged sequentially and at intervals between the two support members 2 along the first direction; at least some of the positioning rods 4 can be slidably inserted into or pulled out of the second insertion through holes 21 of the corresponding support member 2, the first insertion through holes 121 of the corresponding connecting member 1, and the corresponding plug holes of the corresponding cylinder head 6 along the first direction, and the remaining positioning rods 4 can be slidably inserted into or pulled out of the first insertion through holes 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 connector 1 can be a rectangular base or a grid-shaped frame structure, and a first insertion through hole 121 with a rectangular or circular cross-section is provided on the connector 1, which extends along its own thickness direction; furthermore, the support 2 can be a base, rod, or plate, and a second insertion through hole 21 with a rectangular or circular cross-section is provided on the support 2, which extends along its own thickness direction.

[0059] Correspondingly, the lower end of the mounting part 3 has a rectangular or trapezoidal boss, which can be engaged in the T-slot above the milling machine table and can move into place along the length of the T-slot. The upper end of the mounting part 3 has a snap-fit ​​structure or a threaded structure, so that the connecting part 1 can be installed on the connecting part 1. Preferably, the mounting part 3 can use a T-slot bolt to reduce the cost of the clamping device. The positioning rod 4 is a straight rod, and at least one end is used to insert the cylinder head 6. The number of first insertion through holes 121 on a connecting part 1 is greater than or equal to two, so that the cylinder head 6 can be clamped by a number of positioning rods 4 inserted on adjacent connecting parts 1.

[0060] When using, such as Figure 1 As shown, two support members 2 are arranged along the X direction and placed on the milling machine's worktable. The second insertion through hole 21 of one support member 2 shares the same diameter as the corresponding second insertion through hole 21 of the other support member 2, and the center line of the second insertion through hole 21 is parallel to the line connecting the two support members 2. Then, the lower ends of several mounting parts 3 are inserted into the corresponding T-slots in the milling machine's worktable between the two support members 2, and the mounting parts 3 are pushed to move along the T-slots to a preset position. Several connecting parts 1 are installed on the upper ends of the corresponding mounting parts 3. The cylinder head 6 is placed on the milling machine's worktable between the two support members 2, so that the mounting parts 3 and the cylinder head 6 are arranged alternately along the line connecting the two support members 2. Among the mounting parts 3 and cylinder heads 6 arranged in rows along the X direction, the mounting parts 3 are located at the two ends. Then, the two ends of the positioning rod 4 inserted on the connecting part 1 can be inserted into adjacent cylinder heads 6, or adjacent cylinder heads 6 and support members 2 can be inserted into each other.

[0061] This configuration allows for the positioning of several cylinder heads 6, enabling simultaneous milling of multiple cylinder heads 6 using a milling machine, while also preventing the cylinder heads 6 from being suspended in the air, effectively avoiding any displacement of the cylinder heads 6 during processing.

[0062] Based on the above embodiment, the connector 1 has a third insertion through hole 111 for inserting the second end of the mounting member 3; it also includes a fixing member 5 for being detachably installed on the second end of the mounting member 3 to cooperate with the second limiting part of the mounting member 3 to clamp the connector 1.

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

[0064] It should be noted that the type of fastener 5 is not limited, as long as it is detachably mounted on the mounting part 3. For example, in some specific embodiments, the fastener 5 can be a pin with an opening tendency. Correspondingly, the mounting part 3 has an elongated through hole, and the dimension of the elongated through hole along the length direction of the mounting part 3 is larger than the dimension along the width direction of the mounting part 3. (Refer to...) Figure 1 As shown, the vertical dimension of the strip-shaped through hole is larger than that of the horizontal dimension. The fastener 5 can be inserted into the elongated through hole of the mounting part 3 and has a tendency to open vertically to press the corresponding connector 1.

[0065] Based on the above embodiments, a portion of the first insertion through holes 121 is located on one side of the third insertion through hole 111, and the remaining first insertion through holes 121 are located on the other side of the third insertion through hole 111; and the connector 1 has a centrally symmetrical structure, with the symmetrical central axis of the connector 1 passing through the midpoint of the center line of the third insertion through hole 111 and parallel to the center line of the first insertion through hole 121.

[0066] like Figure 7 As shown, the axis of symmetry of connector 1 is the center line extending perpendicular to the paper, passing through the midpoint of the axis of the third insertion hole 111. Connector 1 is centered on... Figure 1 The current orientation, after rotating 180° around the aforementioned axis of symmetry, will then be in conjunction with... Figure 1 The connector 1 is aligned with the orientation shown. With this configuration, the connector 1 can be rotated 180° around the aforementioned symmetrical central axis during use, so that the first insertion holes 121 located on both sides of the third insertion hole 111 can be subjected to tension or pressure intermittently, thereby extending the service life of the connector 1.

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

[0068] like Figures 7 to 9 As shown, in connector 1, the main body 11 is used to connect and support the first bracket 12 and the second bracket 13, which have the first insertion through hole 121, and is used to insert and mate the mounting part 3. The main body 11 can be a rectangular or circular column. The first bracket 12 is connected to the left end of the main body 11, the third insertion through hole 111 is opened in the middle 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 be an arch-shaped structure or a cylindrical structure. This arrangement not only makes it easier to ensure the bending resistance of connector 1, but also makes it easier to reduce the manufacturing cost of connector 1.

[0069] Based on the above embodiment, the fastener 5 is a nut structure, which is sleeved on the outside of the second end of the corresponding mounting part 3 and threadedly engaged with it.

[0070] like Figure 2 , Figure 3 and Figure 4 As shown, the fastener 5 adopts a nut structure with a threaded hole. When in use, the fastener 5 is sleeved on the outer side of the upper end of the mounting part 3, and the fastener 5 is rotated to make it abut against the upper end of the connector 1, so as to reduce the installation difficulty of the fastener 5.

[0071] Based on the above embodiments, it also includes a support component, a controller, a first slide rail, a second slide rail, a third slide rail, and a plurality of first positioning components, second positioning components, and third positioning components; the first slide rail, the second slide rail, and the third slide rail can be mounted on the milling machine worktable via the support component; the first slide rail, the second slide rail, the third slide rail, the first positioning components, the second positioning components, and the third positioning components are all signal-connected to the controller; the tail ends of the plurality of first positioning components are installed on the corresponding sliders of the first slide rail, and the free ends of the plurality of first positioning components are used to connect and position the corresponding support member 2, the cylinder head 6, and the mounting member 3; the tail ends of the second positioning components are installed on the sliders of the second slide rail, and the free ends of the second positioning components are used to install the fixing member 5; the tail ends of the third positioning components are installed on the sliders of the third slide rail, and the free ends of the third positioning components are used to pick up the positioning rod 4 and insert it into a preset position.

[0072] The first, second, and third slide rails each include guide rails and sliders, and several guide rails are parallel to each other. Several guide rails are set on the milling machine worktable by a support assembly. For example, the bottom of the support assembly has the aforementioned first limiting part 31, and several sliders can slide along the corresponding guide rails.

[0073] refer to Figure 1 The orientation shown does not limit the arrangement of the first, second, and third slide rails. For example, in some specific embodiments, the first slide rail is located on 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. It should also be noted that the type of support component is not limited, as long as it meets the installation requirements. For example, in some specific embodiments, the support component includes several support legs, and the two ends of the guide rail are connected to the top ends of the corresponding support legs. Or, in other specific embodiments, the support component includes at least two sets of frames, with one end of several guide rails connected to one set of frames and the other end connected to another set of frames.

[0074] Correspondingly, several first positioning components are disposed on the corresponding sliders of the first slide rail, for reference. Figure 1 As shown, when each support member 2 and cylinder head 6 needs to be placed sequentially from left to right, several first positioning components arranged from left to right sequentially clamp one support member 2, one cylinder head 6, another cylinder head 6, another cylinder head 6, ..., another support member 2, and arrange the clamped structures sequentially along the X direction, that is, arrange one support member 2, one cylinder head 6, another cylinder head 6, another cylinder head 6, ..., another support member 2 sequentially from left to right on the milling machine worktable.

[0075] Furthermore, the second positioning component is disposed on the slider of the second slide rail to pick up the fixing member 5 and install the fixing member 5 on the upper end of the corresponding mounting member 3; similarly, the third positioning component is disposed on the slider of the third slide rail to pick up the positioning rod 4 and insert it into the preset position.

[0076] Secondly, the first slide rail, the second slide rail, the third slide rail, the first positioning component, the second positioning component, and the third positioning component 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 component, the second positioning component, and the third positioning component through the controller. For example, the controller can control the direction and distance of movement of the slide rail, or control the positioning component to perform actions such as gripping, releasing, and installing corresponding parts. With this configuration, the clamping device has a high degree of automation, which helps to reduce the labor intensity of operators.

[0077] It should be noted that there are no restrictions on the types of the first positioning component, the second positioning component, and the third positioning component, as long as they can achieve the above functions. For example, a robotic arm with a mechanical gripper at the free end can be used, or a telescopic arm with a vacuum suction cup at the free end can also be used.

[0078] Based on the above embodiments, a plurality of second insertion through holes 21 may extend with the corresponding first insertion through holes 121 of the upright connector 1 to fix the upright cylinder head 6 with the first machining surface facing the top by the positioning rod 4; and a plurality of second insertion through holes 21 may extend with the corresponding first insertion through holes 121 of the inverted connector 1 to fix the inverted cylinder head 6 with the second machining surface facing the top by the positioning rod 4, and the first machining surface and the second machining 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 end of the positioning rod 4 inserted into the cylinder head 6 at the two ends is suspended. The clamping device is provided with a support member 2 for inserting the other end of the positioning rod 4 that is suspended, so as to ensure the clamping performance of the several cylinder heads 6.

[0080] To illustrate this, for example, in order to insert the leftmost positioning rod 4 into the plug hole of the leftmost cylinder head 6 from left to right, a second insertion through hole 21 extending in the X direction is provided on the support member 2. When machining the first machining surface of the cylinder head 6, such as... Figure 2 As shown, the cylinder head 6 is positioned upright so that the first machined surface faces upwards, the connecting piece 1 is positioned upright, and the positioning rod 4 is inserted as shown. Figure 5 and Figure 6 The second insertion through holes 21 in the support member 2, located at the lower left and upper right, are then passed through the corresponding first insertion through holes 121 of the connector 1 and the corresponding plug holes of the cylinder head 6 in sequence; conversely, when machining the second machined surface of the cylinder head 6, as shown... Figure 3 As shown, the cylinder head 6 is inverted so that the second machined surface faces upward, the connecting piece 1 is inverted, and the positioning rod 4 is inserted as shown. Figure 5 and Figure 6 The second insertion through hole 21 in the upper left and lower right of the support member 2 is shown, and then it can be passed through the corresponding first insertion through hole 121 of the connector 1 and the corresponding plug hole of the cylinder head 6 in sequence.

[0081] It should be noted that the number and arrangement of the second insertion holes 21 are not limited, as long as the above functions can be achieved. For example, in some specific embodiments, such as... Figure 5As shown, the support member 2 is provided with two sets of second insertion through holes 21 arranged vertically side by side. Alternatively, in some other specific embodiments, the number of first insertion through holes 121 is two, and the number of second insertion through holes 21 is three. The three second insertion through holes 21 are arranged in a triangular pattern, with two second insertion through holes 21 arranged vertically and the remaining second insertion through hole 21 located at the middle height of the side of the other two second insertion through holes 21. Figure 7 As shown, the connector 1 has two first insertion holes 121 arranged horizontally. Correspondingly, when the connector 1 is upright or inverted, one second insertion hole 21 is used on the left side. When the connector 1 is upright, one second insertion hole 21 is used on the upper right side. When the connector 1 is inverted, one second insertion hole 21 is used on the lower right side.

[0082] Based on the above embodiment, the positioning rod 4 is a cylindrical rod, and the second insertion through hole 21 and the first insertion through hole 121 are both cylindrical through holes. This arrangement helps to improve the positioning accuracy of the cylinder head 6.

[0083] In addition to the clamping device described above, the present invention also provides a processing method applicable to the clamping device disclosed in the above embodiments, the processing method comprising the following steps:

[0084] Step S1: Scribing is performed on the cylinder head 6 to mark the first and second machining surfaces to be machined; it can be understood that marking the surfaces to be machined on the cylinder head 6 is to prepare for aligning the cylinder head 6 at high speed during subsequent machining, so as to ensure machining accuracy.

[0085] Step S2: Arrange the support member 2, mounting member 3, and cylinder head 6 along the first direction on the milling machine worktable, such that the two support members 2 are located at the two ends, and several mounting members 3 and several cylinder heads 6 are alternately arranged between the two support members 2, with adjacent support members 2 being corresponding mounting members 3; and install several connecting members 1 on the top of the corresponding mounting members 3; it can be understood that the clamping device and several cylinder heads 6 to be processed are arranged on the milling machine worktable, such as Figure 1 As shown, a support 2, a mounting 3, a cylinder head 6, another mounting 3, another cylinder head 6, another mounting 3, another cylinder head 6, ..., another mounting 3, and another support 2 are arranged sequentially along the first direction; and several connecting parts 1 are installed on the corresponding mounting parts 3 to facilitate the subsequent installation of positioning parts, so as to position the cylinder head 6.

[0086] Step S3: Insert a portion of the positioning rods 4 into the second insertion through hole 21 of the support member 2, the first insertion through hole 121 of the corresponding connector 1, and the corresponding cylinder head 6, and insert the remaining portion of the positioning rods 4 into the first insertion through hole 121 of the corresponding connector 1 and the two corresponding cylinder heads 6; it can be understood that inserting several positioning rods 4 is to cooperate in pressing several cylinder heads 6 to be processed, such as Figure 1 As shown, at least two positioning rods 4 on the left are inserted into the left end support 2, connector 1 and cylinder head 6; at least two positioning rods 4 on the right are inserted into the right end support 2, connector 1 and cylinder head 6; and several positioning rods 4 in the middle are inserted into the corresponding connector 1 and the two adjacent cylinder heads 6.

[0087] Step S4: Adjust the height of the clamping device so that the first or second machining surfaces of the cylinder heads 6 are coplanar. This can be understood as adjusting the height of some or all of the support members 2, mounting members 3, connecting members 1, and positioning rods 4. For example, inserting shims under the mounting members 3 and support members 2 to adjust their height, and / or, fitting shims or modular connecting terminals on the upper exterior of the mounting members 3 to adjust the height of the connecting members 1 on the mounting members 3. By adjusting the height of the mounting members 3, support members 2, and connecting members 1, the positioning member is adjusted to raise or lower the cylinder heads 6, so that the markings on the cylinder heads 6, such as scribing lines or marking points, extend coplanarly, allowing the coplanar extension of the surfaces of the cylinder heads 6 to be machined. This enables the cylinder heads 6 to be machined in one operation using a milling cutter.

[0088] Step S5: Tighten the fixing member 5 to press the connecting member 1; it can be understood that after adjusting the height of the clamping device, the connecting member 1 is pressed by the fixing member 5 to prevent the cylinder head 6 from shifting during the processing.

[0089] Step S6: Check whether the first or second machining surfaces of the cylinder heads 6 to be machined are coplanar. If so, milling cutter can be used for machining. If not, alignment is performed to ensure that the first or second machining surfaces of the cylinder heads 6 to be machined are coplanar. It is understood that, in order to improve machining accuracy, after the cylinder heads 6 are fixed, the markings of the cylinder heads 6 are checked again to align the cylinder heads 6 that do not meet the height requirements, i.e., fine-tuning the adjacent mounting parts 3, connecting parts 1, positioning rods 4 and fixing parts 5, etc.
