Description

Technical Field

[0001] This utility model relates to the technical field of ship tappet processing equipment, and in particular to a clamping mechanism for ship tappet processing. Background Technology

[0002] Tappets are key components of the valve train of marine diesel engines. As followers of the cam, their core function is to accurately transmit the axial movement and force of the cam to the pushrod or valve, while bearing the lateral force applied by the cam and transmitting it to the engine block or cylinder head. Their structure is divided into two main categories: mechanical tappets and hydraulic tappets. Mechanical tappets include flat tappets and roller tappets. The former has a simple structure and low cost, while the latter reduces wear through rolling friction and is mostly used in large, high-speed internal combustion engines. Hydraulic tappets, on the other hand, automatically compensate for valve clearance through hydraulic pistons to achieve zero-clearance operation, significantly reducing mechanism impact, wear and noise, and improving operational stability.

[0003] In the machining of ship tappets, the core function of the clamping mechanism is to firmly fix the workpiece to ensure machining accuracy, improve efficiency, and ensure operational safety. However, when the existing clamping mechanism can only clamp the outer side of a single edge of the tappet, it will cause significant process stability problems. Ship tappets are usually large in size and heavy in weight, and the surface area to be machined is large. The single-sided clamping method is essentially a cantilever beam fixation. When subjected to the strong cutting forces and periodic vibrations generated by milling, drilling and other processes, this clamping method will cause the workpiece to twist around the clamping point and shake as a whole. The direct consequence is increased machining vibration, which makes it difficult to guarantee the dimensional accuracy and surface finish of the machined surface. It may also cause abnormal tool wear or even chipping. In addition, since the clamping force is concentrated on one side, there is a risk of the workpiece loosening under heavy machining, which constitutes a serious safety hazard. Utility Model Content

Detailed Implementation

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1:

[0030] Reference Figures 1-7 This is the first embodiment of the present invention. This embodiment provides a clamping mechanism for processing ship tappets, including a fixed frame 1 and a tappet body 4. A support plate 2 is fixed to the top of the fixed frame 1. A rotating member 3 is provided on one side of the fixed frame 1. A clamping assembly 5 for clamping the tappet body 4 is provided on one side of the rotating member 3. A stabilizing assembly 6 for cooperating with the clamping assembly 5 is provided on the top of the support plate 2.

[0031] This device uses a fixed frame 1 as a basic support structure, with a support plate 2 set on top to form a processing platform. A rotating component 3 on one side works with a clamping assembly 5 to rotate and clamp the tappet body 4. A stabilizing assembly 6 on the top of the support plate 2 clamps and stabilizes the tappet body 4 from the other side. This two-way cooperation design can effectively disperse the vibration stress during processing, avoid the increased vibration caused by unilateral clamping, thereby improving processing accuracy and reducing the risk of abnormal tool wear, ensuring the safety and stability of the overall operation of the device.

[0032] The clamping assembly 5 includes a column 51 disposed on one side of the rotating member 3. A driving member 52 is disposed inside the column 51. Two sets of toothed plates 53 are disposed on the outer side of the driving member 52. Two sets of connecting plates 54 are fixed to one side of each set of toothed plates 53 by bolts. Two sets of clamping plates 55 for clamping the pusher body 4 are fixed to one side of each set of connecting plates 54. A mounting plate 56 is fixed to one side of the column 51 by bolts, and the outer sides of the two sets of connecting plates 54 are slidably connected to the inner wall of the mounting plate 56.

[0033] The clamping assembly 5 drives the gear 522 to rotate via the second motor 521 inside the column 51. The gear 522 meshes with two sets of toothed plates 53, driving the toothed plates 53 to move in opposite directions. The toothed plates 53 are connected to the clamping plates 55 via the connecting plate 54, so that the two sets of clamping plates 55 clamp the push rod body 4 inward synchronously. By setting the mounting plate 56, the toothed plates 53, the connecting plate 54 and the clamping plates 55 can be easily installed, ensuring that the clamping plates 55 move smoothly and avoid deviation. The inner wall of the clamping plate 55 has a slot, which is designed according to the common outer contour of the push rod body 4. When the push rod body 4 is placed in the slot, it can achieve preliminary positioning.

[0034] The stabilizing component 6 includes a support frame 61 that slides on the top of the support plate 2. A turntable 62 rotates on one side of the support frame 61. A threaded rod 63 is fixed on one side of the turntable 62. A threaded sleeve 64 is threadedly connected to the outer side of the threaded rod 63. A stabilizing rod 65 for stabilizing the tappet body 4 is rotatably connected to one end of the threaded sleeve 64 via a rotating shaft.

[0035] The stabilizing component 6 adjusts its position by sliding the support frame 61 on the support plate 2. The turntable 62 drives the threaded rod 63 to rotate. After being limited by the sliding plate, the threaded sleeve 64 moves axially, causing the stabilizing rod 65 to insert into the slot of the tappet body 4. The fastener 13 tightens the horizontal groove of the support frame 61 by rotating the bolt through the rocker arm, and performs a secondary locking on the threaded sleeve 64 to prevent the stabilizing rod 65 from loosening. This design realizes the extension and retraction of the stabilizing rod 65 through threaded transmission. Together with the adjustable support frame 61, it forms a bidirectional force support, which significantly improves the processing stability.

[0036] It is explained here that the support frame 61 has a rotating bolt inside, and a retaining plate is connected to the outer thread of the lower end of the bolt. This retaining plate is located on the inner wall of the support plate 2, and a nut is connected to the outer thread of the bolt. This nut fits against the bottom of the retaining plate. When the operator loosens the bolt, the retaining plate will not fit tightly against the inner wall of the support plate 2, which makes it easy to adjust the position of the support frame 61. After adjusting the position, tightening the bolt will make the retaining plate fit tightly against the inner wall of the support plate 2, which will lock and limit the position of the support frame 61.

[0037] Two sets of sliding plates are fixed to the outer side of the threaded sleeve 64. These sliding plates are attached to the inner wall of the support frame 61. Figure 7 As can be seen from the cross-sectional view, when the threaded rod 63 rotates, the threaded sleeve 64, after being limited by the sliding plate, can only move to the left or right and will not rotate with the threaded rod 63.

[0038] Example 2:

[0039] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, the rotating component 3 includes a first motor 31 fixed to one side of the fixed frame 1. The output end of the first motor 31 is fixed with a rotating rod 32, and the rotating rod 32 passes through the inner wall of the fixed frame 1 and is fixed to the column 51 by bolts.

[0041] The rotating component 3 drives the rotating rod 32 to rotate via the first motor 31. The rotating rod 32 is bolted to the column 51, which drives the entire clamping assembly 5 to rotate synchronously. This design allows the tappet body 4 to adjust its angle as needed during processing, such as to achieve multi-face milling or drilling without re-clamping, thus improving processing efficiency.

[0042] Specifically, the driving component 52 includes a second motor 521 fixed to the inner wall of the column 51. The output end of the second motor 521 is fixed with a gear 522, and the outer side of the gear 522 meshes with the inner wall of the two sets of toothed plates 53.

[0043] The second motor 521 is designed to drive the gear 522 to rotate. After the gear 522 is driven, it can drive the two sets of toothed plates 53 to move.

[0044] Specifically, a mounting plate 7 is fixed to one side of the mounting plate 56 by bolts, a support rod 8 is fixed to one side of the mounting plate 7, and a limit plate 9 is fixed to the other end of the support rod 8.

[0045] The support rod 8 can be easily fixed by setting the mounting plate 7. The design of the support rod 8 makes it easy to fix the limiting plate 9. The limiting plate 9 can be easily used to limit the position of the tappet body 4, preventing the tappet body 4 from coming out of the slots of the two sets of clamping plates 55.

[0046] Example 3:

[0047] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0048] Specifically, a storage slot 10 is fixed to the top of the fixed frame 1, and a collection frame 11 slides on the inner wall of the storage slot 10.

[0049] By setting up the storage tank 10, water during processing can be easily collected; by setting up the collection box 11, iron filings during processing can be easily collected.

[0050] Specifically, the top of the fixing frame 1 is fixed with four fixing rods 12 by bolts, and the four fixing rods 12 are evenly distributed on both sides of the support plate 2 and connected to the support plate 2 by bolts.

[0051] By setting four fixing rods 12, the stability of the connection between the fixing frame 1 and the support plate 2 can be easily improved.

[0052] Specifically, the inner wall of the support frame 61 is provided with fasteners 13 for securing the threaded sleeve 64.

[0053] Depend on Figure 6 It is known that a transverse groove is provided inside the support frame 61, and two sets of lugs with threaded holes are fixed outside the transverse groove of the support frame 61. The fastener 13 consists of a rocker arm and a bolt. The bolt and the two sets of lugs are threadedly connected. When it is necessary to limit the threaded sleeve 64, simply turn the rocker arm. The rocker arm rotates and drives the bolt to rotate. After the bolt rotates, the transverse groove can be tightened, and the threaded sleeve 64 can be locked.

[0054] When in use, the clamping plate 55 initially clamps the object;

[0055] The staff places the tappet body 4 between two sets of clamping plates 55. The fitting grooves on the inner wall of the clamping plates 55 can fit the outline of the tappet body 4 to achieve initial positioning. After starting the second motor 521, its output end drives the gear 522 to rotate. The gear 522 meshes with the two sets of toothed plates 53 to transmit the rotational motion, which is converted into the linear movement of the toothed plates 53. The toothed plates 53 drive the clamping plates 55 to retract inward synchronously through the connecting plate 54, and the mechanical clamping force is used to complete the initial fixation of the tappet body 4.

[0056] The principle of position adjustment of support frame 61;

[0057] The support frame 61 moves laterally through the sliding engagement between the bottom clamping plate and the inner wall of the support plate 2. During adjustment, the bolts inside the support frame 61 are loosened to reduce the friction between the clamping plate and the inner wall of the support plate 2. At this time, the support frame 61 can be manually pushed to the designated position. After the position is determined, the bolts are tightened to press the nut against the clamping plate. Mechanical locking is achieved by increasing the friction, ensuring that the support frame 61 remains stable under processing vibration, and providing a basis for the subsequent alignment of the stabilizing rod 65.

[0058] The principle of the stabilizing rod 65 clamping;

[0059] Rotating the turntable 62 drives the threaded rod 63 to rotate. Due to the sliding constraint between the outer sliding plate and the inner wall of the support frame 61, the threaded sleeve 64 can only move linearly along the axial direction. When the threaded sleeve 64 moves, it drives the stabilizing rod 65 to insert into the slot of the tappet body 4, forming a mechanical limit. Subsequently, rotating the rocker arm of the fastener 13 causes the threaded engagement of the bolt and the lug of the support frame 61 to tighten the transverse groove. By reducing the gap of the transverse groove, the axial degree of freedom of the threaded sleeve 64 is restricted. This double locking mechanism can effectively resist the cutting force and vibration generated during processing, ensure the connection rigidity between the stabilizing rod 65 and the tappet body 4, and prevent the workpiece from loosening or shifting.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
