Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a cushion block for mechanical processing. Background Art

[0002] In the field of mechanical processing, precision and stability are the key to ensuring product quality and processing efficiency. When one end of a mechanical part is in a low position, it is particularly important to accurately adjust its height. At this time, the use of pads becomes indispensable. As an auxiliary tool, the main function of the pad is to steadily lift one end of the part to a preset height to ensure the overall flatness of the part. This step is crucial to the subsequent processing flow because it directly affects the accuracy of the processed surface and the smooth progress of the processing. By using pads, errors caused by uneven positions of parts can be eliminated, allowing the processing tool to operate according to a predetermined trajectory, thereby ensuring the accuracy of the processing size and shape.

[0003] The pads used in existing mechanical processing are generally triangular wooden blocks with fixed angles. However, during use, it is found that the pads lack flexibility due to the fixed angles and are difficult to perfectly match mechanical parts of various shapes, sizes and processing requirements. This forces producers to prepare pads of various angles to cope with changing processing scenarios, which is not only costly but also restricts the improvement of work efficiency. In addition, the problem of uneven force distribution should not be ignored. Limited by the fixed contact angle and small contact area, the pads are often difficult to achieve full fit with the parts, resulting in concentrated force lines and excessive local pressure. This unbalanced force state accelerates the wear of the pads themselves and is also prone to cause unnecessary pressure concentration and damage to the parts, ultimately affecting the accuracy, quality and even overall service life of the finished product.

[0030] (III) Beneficial Effects

[0031] Compared with the prior art, the technical solution of the present application has the following beneficial technical effects:

[0032] This cushion block for mechanical processing realizes high flexibility and adaptability by designing a structure including a bottom plate, an inclined abutting block, a pushing member and a bottom supporting member. Firstly, the inclined abutting block is connected to the end of the bottom plate by a hinge, and this design enables the inclined abutting block to rotate and displace according to the end of the bottom plate, so that the contact angle with the end of the component can be dynamically adjusted according to the specific shape and size requirements of different mechanical processing components. This adjustable angle design completely solves the problem that traditional fixed-angle cushion blocks are difficult to match the changing processing requirements, greatly improves the versatility and flexibility of the cushion block, reduces the cost of producers due to preparing multiple-angle cushion blocks, and significantly improves the work efficiency. Secondly, the pushing member is located between the bottom plate and the inclined abutting block. By adjusting the pushing member, the included angle between the inclined abutting block and the bottom plate can be conveniently changed, so as to achieve precise adaptation to different mechanical processing components. This design not only simplifies the use process of the cushion block, but also improves the accuracy and stability during the processing, ensuring the accuracy of the processing dimensions and shapes. In addition, the addition of the bottom supporting member further enhances the supporting performance of the cushion block. It is arranged on one side surface of the bottom plate and close to one end of the mechanical processing component, contacts with the bottom of the component, and provides additional supporting force. This design not only helps to disperse the force, avoid the concentration of force lines and excessive local bearing pressure, but also enhances the stability between the cushion block and the component, reducing the risk of displacement or damage caused by vibration or impact. At the same time, the bottom supporting member can also protect the bottom of the component to a certain extent, preventing it from being unnecessarily worn or damaged. Description of the Drawings

Detailed implementation mode

[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0038] Combined with Figures 1 - 3 As shown, a cushion block for machining of the present utility model includes:

[0039] A bottom plate 1, which is arranged in a horizontal direction as a whole;

[0040] An inclined abutting block 2, which is hinged to the end of the bottom plate 1 and can rotate and displace according to the end of the bottom plate 1. One side surface of the inclined abutting block 2 can be in contact with the end of the parts in machining;

[0041] A pushing member 3, which is arranged between the bottom plate 1 and the inclined abutting block 2 and is used to adjust the angle between the inclined abutting block 2 and the bottom plate 1 to adapt to various machining parts;

[0042] A bottom supporting member 4, which is arranged on one side surface of the bottom plate 1. One end of the bottom supporting member 4 close to the machining parts is in contact with the bottom of the machining parts and supports the bottom of the machining parts.

[0043] First, the bottom plate 1, as the basic part of the entire cushion block, is arranged horizontally as a whole, providing a stable support platform for other components. The stability of the bottom plate 1 ensures that the cushion block will not undergo unnecessary displacement or inclination due to external forces during use. Next, the inclined abutment block 2 is connected to the end of the bottom plate 1 by means of a hinge. This connection method enables the inclined abutment block 2 to rotate and displace around the hinge point. When one end of the machined part is at a lower position, the rotation function of the inclined abutment block 2 becomes particularly important. By adjusting the rotation angle of the inclined abutment block 2, one side surface thereof can closely contact the end of the machined part, thereby smoothly lifting the part to the preset height and ensuring the overall flatness of the part. To achieve precise adjustment of the angle of the inclined abutment block 2, the pushing member 3 is arranged between the bottom plate 1 and the inclined abutment block 2, thereby changing the included angle between the inclined abutment block 2 and the bottom plate 1. The user can precisely adjust the angle of the inclined abutment block 2 by operating the pushing member 3 according to the specific shape and size requirements of the machined part, so as to achieve a perfect fit between the cushion block and the part. In addition, to further enhance the support performance of the cushion block, the bottom supporting member 4 is arranged on one side surface of the bottom plate 1. One end of the bottom supporting member 4 close to the machined part contacts the bottom of the part and provides additional supporting force. This design not only helps to disperse the force and reduce the load on the inclined abutment block 2, but also improves the stability between the cushion block and the part, preventing displacement or damage caused by vibration or impact. In summary, the cushion block for machining realizes the efficient and stable support of the machined part through the stable support of the bottom plate 1, the rotational displacement of the inclined abutment block 2, the precise adjustment of the pushing member 3, and the additional support of the bottom supporting member 4, ensuring the smooth progress of the machining process and the improvement of the machining quality.

[0044] In a preferred embodiment of the present utility model, it can be further configured as follows: As Figures 1 to 3As shown in the figure; two shaft rods 5 are fixedly installed at the end of the bottom plate 1. A rotating sleeve 6 is sleeved on the outer side of each of the two shaft rods 5. The rotating sleeve 6 is axially rotatably connected to the outer side of the shaft rod 5. One end of one side of the inclined abutting block 2 is fixedly connected to the rotating sleeve 6. The inclined abutting block 2 is rotatably connected to the bottom plate 1 through the shaft rod 5 and the rotating sleeve 6. At the end of the bottom plate 1, two shaft rods 5 are fixedly installed. These two shaft rods 5 are the core components of the rotational connection, providing a stable support point for the rotation of the inclined abutting block 2. The design of the shaft rod 5 needs to ensure its accurate position and firm fixation to withstand various forces and torques generated during the rotation of the inclined abutting block 2. Then, a rotating sleeve 6 is sleeved on the outer side of each shaft rod 5. The rotating sleeve 6 is axially rotatably connected to the outer side of the shaft rod 5 through a specific bearing or sliding structure, enabling the rotating sleeve 6 to freely rotate around the central axis of the shaft rod 5. This rotational connection design allows the rotating sleeve 6 to smoothly perform rotational movement along the axial direction of the shaft rod 5 when subjected to an external force without jamming or damage. One end of one side of the inclined abutting block 2 is fixedly connected to the rotating sleeve 6. This connection method can be welding, bolt connection or other reliable mechanical connection methods to ensure that the inclined abutting block 2 and the rotating sleeve 6 maintain synchronous movement during rotation. Due to the rotational connection between the rotating sleeve 6 and the shaft rod 5, the inclined abutting block 2 can also be rotatably connected to the bottom plate 1 through the shaft rod 5 and the rotating sleeve 6.

[0045] In a preferred embodiment of the present utility model, it can be further configured as follows: As Figures 1 to 3 shown; the pushing member 3 includes:

[0046] A fixed block 31, fixedly installed on the surface of the bottom plate 1 close to the inclined abutting block 2, and a threaded hole is machined on the fixed block 31;

[0047] A screw rod 32, threadedly connected to the threaded hole of the fixed block 31;

[0048] A pushing block 33, arranged at the end of the screw rod 32, and it can be displaced laterally under the drive of the screw rod 32;

[0049] A synchronous rod 34, fixedly installed on the surface of the pushing block 33; and

[0050] The diagonal strut 35 has one end hinged to the outer side of the synchronizing rod 34 and the other end hinged to one side surface of the inclined abutting block 2. The pusher 3 is a key component for adjusting the angle between the inclined abutting block 2 and the bottom plate 1. The fixing block 31 is fixedly installed on one side surface of the bottom plate 1 close to the inclined abutting block 2 and serves as the fixing foundation for the entire pusher 3. A threaded hole is machined on the fixing block 31, which provides the possibility for threaded connection of subsequent components. Then, the screw rod 32 is installed in the threaded hole of the fixing block 31 by means of threaded connection. The rotational movement of the screw rod 32 will be converted into a linear movement along its axis, which is the key to realizing the pushing function. When the user rotates the screw rod 32, due to the meshing effect of the threads, the screw rod 32 will displace along its axis. To push the inclined abutting block 2, a pushing block 33 is provided at the end of the screw rod 32. The pushing block 33 moves laterally as the screw rod 32 displaces, and this lateral displacement will be converted into an adjustment force for the inclined abutting block 2. To provide a stable movement track and connection point for the pushing block 33, the synchronizing rod 34 is fixedly installed on the surface of the pushing block 33. The design of the synchronizing rod 34 ensures the stability and directionality of the pushing block 33 during movement. Finally, the diagonal strut 35 serves as a bridge connecting the synchronizing rod 34 and the inclined abutting block 2. One end of it is hinged to the outer side of the synchronizing rod 34, and the other end is hinged to one side surface of the inclined abutting block 2. This hinged connection method enables the diagonal strut 35 to transmit force and torque between the synchronizing rod 34 and the inclined abutting block 2, and at the same time allows the inclined abutting block 2 to rotate around its hinge point. When the pushing block 33 is driven by the screw rod 32 to displace laterally, the synchronizing rod 34 drives the diagonal strut 35 to move, thereby pushing the inclined abutting block 2 to rotate around its hinge point, so as to change the angle between the inclined abutting block 2 and the bottom plate 1.

[0051] In a preferred embodiment of the present utility model, it can be further configured as: as Figures 1 to 3 shown; a through hole is machined on one side surface of the pushing block 33 close to the screw rod 32, and a bearing is arranged in the through hole. One side surface of the screw rod 32 close to the pushing block 33 is connected to the inner ring of the bearing. In the pusher 3, the pushing block 33 is a key component connecting the screw rod 32 and the diagonal strut 35, and its design is crucial for the smooth operation of the entire pushing system. To reduce the frictional resistance of the pushing block 33 under the rotational drive of the screw rod 32 and improve the accuracy and efficiency of displacement transmission, a through hole is machined on one side surface of the pushing block 33 close to the screw rod 32. A bearing is arranged in this through hole. The inner ring of the bearing is connected to one side surface of the screw rod 32 close to the pushing block 33, and the outer ring is fixed or supported in the through hole of the pushing block 33. When the user rotates the screw rod 32, the rotational movement of the screw rod 32 first drives the inner ring of the bearing to rotate and does not drive the pushing block 33 to rotate. Therefore, this rotational movement can be transmitted to the pushing block 33 with almost no resistance. This displacement is then transmitted to the inclined abutting block 2 through the synchronizing rod 34 and the diagonal strut 35, so as to change the angle between the inclined abutting block 2 and the bottom plate 1.

[0052] In a preferred embodiment of the present utility model, it can be further configured as follows: as Figures 1 to 3 shown; sliding tracks 7 are fixedly installed on the front and rear surfaces of the fixed block 31. The synchronizing rod 34 is slidably connected to the sliding tracks 7. As a key component connecting the pushing block 33 and the diagonal strut 35, the two ends of the synchronizing rod 34 are respectively connected to the pushing block 33 and the diagonal strut 35 by hinge means. And in the middle part of the synchronizing rod 34, it can move smoothly horizontally along the sliding tracks 7. When the screw rod 32 drives the pushing block 33 to move by rotation, the pushing block 33 transmits this displacement to the diagonal strut 35 through the synchronizing rod 34. During the movement of the synchronizing rod 34, its sliding structure closely fits on the sliding tracks 7, ensuring the smoothness and accuracy of the movement of the synchronizing rod 34. This sliding connection not only reduces the frictional resistance during the movement but also improves the response speed and positioning accuracy of the entire pushing system.

[0053] In a preferred embodiment of the present utility model, it can be further configured as follows: as Figures 1 to 3 shown; the bottom support member 4 includes:

[0054] A connecting plate 41, fixedly installed on the surface of the bottom plate 1 away from the inclined abutting block 2, and there is a driving gap between it and the bottom plate 1;

[0055] A threaded rod 42, one end of which penetrates through the bottom plate 1 and extends to the other surface of the inclined abutting block 2, and the other end is located in the driving gap;

[0056] A rotating handle 43, fixedly installed on one end of the threaded rod 42 and located in the driving gap; and

[0057] The support plate 44 is fixedly installed on the other end of the threaded rod 42. The connecting plate 41 is fixedly installed on the surface of the bottom plate 1 away from the inclined abutting block 2, providing a stable installation foundation for the entire bottom support member 4. It should be noted that a driving gap is deliberately left between the connecting plate 41 and the bottom plate 1. This design provides space for the adjustment and movement of subsequent components. Next, the threaded rod 42, as the core adjustment component of the bottom support member 4, has one end passing through the bottom plate 1 and extending to the other surface of the inclined abutting block 2. The other end of the threaded rod 42 is located within the driving gap, maintaining a certain distance from the connecting plate 41 and the bottom plate 1 for subsequent rotational adjustment. The rotating handle 43 is fixedly installed on one end of the threaded rod 42 located within the driving gap, providing an easy-to-operate handle for the user. The user can drive the threaded rod 42 to rotate in the bottom plate 1 by rotating the rotating handle 43. Therefore, the rotational movement of the rotating handle 43 is converted into the linear movement of the threaded rod 42. Finally, the support plate 44 is fixedly installed on the other end of the threaded rod 42, that is, on the side where the rotating handle 43 is not located. With the linear movement of the threaded rod 42, the support plate 44 will also rise or fall accordingly. This design enables the bottom support member 4 to be flexibly adjusted according to the actual height and support requirements of the machining parts. When it is necessary to increase the support force on the bottom of the parts, the user can rotate the rotating handle 43 to raise the threaded rod 42, thereby driving the support plate 44 to rise and closely adhere to the bottom of the parts; conversely, when it is necessary to reduce the support force or adjust the position of the parts, the user can achieve this by rotating the rotating handle 43 in the reverse direction.

[0058] In a preferred embodiment of the present utility model, it can be further configured as: as Figures 1 to 3As shown in the figure; a threaded sleeve 8 is embedded on the surface of the bottom plate 1. An internal thread adapted to the external thread of the threaded rod 42 is provided inside the threaded sleeve 8. The threaded rod 42 is threadedly connected to the inner side of the threaded sleeve 8. In the design of the bottom support member 4, in order to ensure that the threaded rod 42 can move stably and precisely in the vertical direction, so as to adjust the bottom support force of the machined parts on the support plate 44, the threaded sleeve 8 is embedded on the surface of the bottom plate 1. This threaded sleeve 8 not only provides a firm support point for the threaded rod 42, but also realizes precise threaded connection with the external thread of the threaded rod 42 through the internal thread provided therein. Specifically, the threaded sleeve 8 is carefully designed and firmly embedded in the designated position of the bottom plate 1. The inner hole size and thread specification thereof are exactly matched with the external thread of the threaded rod 42. When one end of the threaded rod 42 passes through the reserved hole on the bottom plate 1 and extends into the threaded sleeve 8, its external thread is tightly engaged with the internal thread of the threaded sleeve 8. This engagement relationship ensures that the threaded rod 42 can move linearly along its axial direction, that is, the vertical direction, when rotating, without lateral deviation or shaking. The user can easily drive the threaded rod 42 to rotate inside the threaded sleeve 8 by rotating the rotating handle 43. Due to the engagement of the threads, the rotational movement of the threaded rod 42 is converted into a linear movement along its axial direction. As the threaded rod 42 rises or falls, the support plate 44 fixedly installed thereon will also move accordingly, so as to realize the adjustment of the bottom support force of the machined parts. In addition, due to the self-locking property of the threaded connection, that is, in the absence of external force, the threaded rod 42 will remain in the current position and will not move by itself, which ensures that the support plate 44 can stably support the bottom of the parts after the adjustment is in place.

[0059] In a preferred embodiment of the present utility model, it can be further configured as: as Figures 1 to 3 shown in the figure; a connection hole 9 is provided on the surface of the inclined abutment block 2. The threaded rod 42 and the support plate 44 are located inside the connection hole 9. In the design of the cushion block for machining, the inclined abutment block 2 is one of the key components. It not only provides lateral support for the machined parts, but also cooperates with other components through its structural design to realize the versatility and flexibility of the entire cushion block. To achieve this, a connection hole 9 is specifically provided on the surface of the inclined abutment block 2. Specifically, when the threaded rod 42 passes through the bottom plate 1 and rotates to adjust the height of the support plate 44, both the threaded rod 42 and the support plate 44 will be located inside the connection hole 9. The connection hole 9 provides the necessary space for the vertical movement of the threaded rod 42 and the support plate 44, avoiding interference between them and the inclined abutment block 2. Secondly, the existence of the connection hole 9 enables the support plate 44 to maintain a certain distance from the inclined abutment block 2 when rising or falling, thus ensuring the relative independence between the two. This relative independence is crucial for adjusting the height of the support plate 44 to adapt to machined parts of different heights.

[0060] The specific working principle of a cushion block for machining is as follows:

[0061] In the initial state of the cushion block for machining, the connecting plate 41 is placed horizontally. The inclined abutting block 2 is hinged to the end of the bottom plate 1 through the shaft rod 5 and the rotating sleeve 6, so that the inclined abutting block 2 can rotate and displace around the shaft rod 5. In order to adapt to the shapes and sizes of different machining parts, first, the angle between the inclined abutting block 2 and the bottom plate 1 is adjusted, which is achieved by the pushing member 3. Specifically, the screw rod 32 is rotated so that it moves in the threaded hole of the fixed block 31. Since the end of the screw rod 32 is provided with a pushing block 33, and the pushing block 33 is connected to the screw rod 32 through a bearing, the rotational movement of the screw rod 32 is converted into the lateral displacement of the pushing block 33. The displacement of the pushing block 33 is transmitted to the inclined strut 35 through the synchronizing rod 34. The other end of the inclined strut 35 is hinged to the inclined abutting block 2. Therefore, the inclined abutting block 2 rotates around the shaft rod 5 under the push of the inclined strut 35, thereby changing the angle with the bottom plate 1, so that one side surface of the inclined abutting block 2 can be in contact with the end of the machining part. During the process of adjusting the angle of the inclined abutting block 2, the sliding track 7 provides a stable sliding path for the synchronizing rod 34, ensuring the smoothness and accuracy of the synchronizing rod 34 during movement;

[0062] At the same time, the bottom supporting member 4 is used to support the bottom of the machining part. The connecting plate 41 is fixedly installed on the side surface of the bottom plate 1 away from the inclined abutting block 2, leaving a driving gap with the bottom plate 1. The threaded rod 42 passes through the bottom plate 1 and is threadedly connected to the threaded sleeve 8 embedded on the surface of the bottom plate 1, so that the threaded rod 42 can move in the vertical direction along the internal thread of the threaded sleeve 8 under the drive of the rotating handle 43. The support plate 44 is fixedly installed on the top of the threaded rod 42 and moves with the lifting and lowering of the threaded rod 42. When the machining part is placed on the cushion block, its bottom contacts the support plate 44. By rotating the rotating handle 43, the height of the support plate 44 can be adjusted to adapt to machining parts of different heights. It should be noted that a connecting hole 9 is opened on the surface of the inclined abutting block 2, and the threaded rod 42 and the support plate 44 are located inside the connecting hole 9. This design ensures that the threaded rod 42 and the support plate 44 will not interfere with the inclined abutting block 2 during the lifting and lowering process, and at the same time provides sufficient support space for the bottom of the machining part. In summary, the cushion block for machining can adapt to machining parts of different shapes and sizes and provide stable and reliable support by adjusting the angle of the inclined abutting block 2 and the height of the bottom supporting member 4.
