Description

Technical Field

[0001] The utility model relates to the technical field of brakes, in particular to a front base processing tool for a weather vane brake. Background Art

[0002] A wind vane brake is a device used to control the movement of a tower crane. During field construction, tower cranes are often very tall and have very long booms. To ensure safety when stopping operations, the boom should be positioned downwind and locked. The wind vane brake is a key device for this purpose. It automatically aligns the boom with the wind and locks it in position, reducing wind impact on the crane and improving safety. The front frame is the foundational support structure for the wind vane brake, playing a crucial role in supporting, securing, and connecting other components. Its machining precision and quality directly determine the overall performance and service life of the brake. To ensure the wind vane brake can be easily and accurately installed on the front frame, holes are drilled on the end face of the front frame. These holes allow for precise positioning of the wind vane brake, ensuring accurate docking between the brake and other components on the frame. The accuracy of the end face holes is crucial for brake installation, effectively improving installation accuracy and thus ensuring reliable operation of the entire tower crane.

[0003] When drilling the end face of the front base, the traditional method of positioning and clamping the front base mainly relies on a mechanical clamping device, that is, a combination of general tools and fixtures is used to process the front base. The specific method is to fix the front base to a platform or a larger component by rotating bolts or using fixtures. This method usually requires the use of tools (such as wrenches or screwdrivers) to rotate to apply the necessary pressure to ensure the fixing effect. However, this method has certain limitations. The combined processing method may result in insufficient positioning accuracy and cannot fully meet the specific requirements of the front base. It will cause an impact in subsequent operations and may cause additional vibration and wear due to inaccurate positioning, which will further lead to displacement problems.

[0004] Specifically, when machining the front base of a wind vane brake, a combination of general-purpose tools and fixtures is still commonly used for positioning and clamping. While this method can accomplish basic machining tasks, it may be insufficient when faced with the higher precision and more stringent quality requirements, and cannot fully meet the high-precision machining demands of modern manufacturing. Therefore, to improve machining accuracy and efficiency, it may be necessary to consider using a dedicated front base positioning and clamping device. Utility Model Content

[0005] The utility model aims to provide a front base processing tool for a wind vane brake, which can realize accurate positioning and reliable pressing of the front base, thereby improving production efficiency and processing accuracy.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A front base processing tool for a weather vane brake, comprising a base plate for supporting a product, a positioning mechanism for circumferentially contacting the surface of the product and positioning the product on the base plate, a clamping mechanism for pressing the product from top to bottom provided above the positioning mechanism; the clamping mechanism comprises a tightening bolt passing through the base plate, a detachable movable pressure plate provided on the upper portion of the tightening bolt, the tightening bolt comprising an integrally connected screw and a screw head; the slot width of the movable pressure plate is larger than the screw diameter and smaller than the screw head; the bottom surface of the movable pressure plate contacts the upper end surface of the product, and the top surface of the base plate contacts the lower end surface of the product; the area where the upper end surface of the product contacts the movable pressure plate is the clamping area, and the area where the upper end surface of the product does not contact the movable pressure plate is the exposed area to be processed.

[0008] The principles and advantages of this solution are: the base plate can support the positioning and pressing functions of the product, the positioning mechanism contacts the outer surface of the product to circumferentially position the product, ensuring that it does not shift during processing, and the pressing mechanism is used to press the product in the vertical direction to ensure that it is stable and motionless during processing. The base plate, pressing mechanism, and positioning mechanism work together on the product, and a force balance is achieved between the three forces, thereby improving the overall pressing, positioning, and stabilization effects of the product.

[0009] When the movable platen is pressed, the product is divided into two areas: the pressing area and the area to be processed. The area where the upper end of the product contacts the movable platen is the pressing area, while the area where the upper end of the product does not contact the movable platen is the exposed area to be processed. When the pressing area presses the product, the area to be processed is revealed, and the two complement each other. The exposed area to be processed allows the processing tool to directly contact the product and can process different sizes of the same product, reducing the time required to adjust the product position and improving production efficiency. The pressing area ensures that the product will not be displaced or vibrated by external forces during processing, improving the stability of the processing process.

[0010] In this solution, when the tightening bolts and the movable pressure plate work together to tighten the product, they serve as a part of the entire special tooling. Compared with scattered tools, the tightening bolts make the various components of the tooling constitute the tooling as a whole, and the front base of the wind vane brake is used in a targeted manner, which can fix the product more quickly.

[0011] Preferably, as an improvement, the positioning mechanism includes a central positioning boss arranged on the top surface of the substrate, the central positioning boss has a boss side surface that can be in contact with the side surface of the product, and there is a gap between the boss side surface and the inner side surface of the product.

[0012] Beneficial effects: By positioning the product through the center positioning boss, the product can be installed quickly and accurately with simple operation, which can reduce product installation time and improve production efficiency.

[0013] Preferably, as an improvement, the positioning mechanism further includes a positioning member connected to the base plate, and the positioning member is used to abut against the outer side surface of the product.

[0014] Beneficial effect: In conjunction with the outward supporting force of the boss, the positioning member provides an inward balancing supporting force, which prevents the product from displacement or vibration during processing, reduces processing errors caused by displacement or vibration, and thus improves the stability of the processing process.

[0015] Preferably, as an improvement, the positioning member includes a rotating positioning pin and a positioning block, the positioning block is provided with a threaded through hole for the rotating positioning pin to pass through and be threadedly connected, one end of the rotating positioning pin after passing through the threaded through hole can abut against the outer side surface of the product, and the rotating positioning pin is rotated to adjust the length of the protruding part of the rotating positioning pin; the positioning block is fixedly connected to the base plate.

[0016] Beneficial effect: The length of the protruding portion of the rotary positioning pin can be adjusted by rotating the rotary positioning pin, and the positioning of the product can be adjusted accordingly, thereby improving the positioning effect.

[0017] Preferably, as an improvement, the bottom of the tightening bolt is connected to a cylinder for driving the tightening bolt to move up and down, and the piston rod of the cylinder is connected to the bottom of the tightening bolt.

[0018] Beneficial effect: The tension bolt driven by the cylinder is tightened up and down, which can realize automatic clamping and separation of products, thereby improving production efficiency.

[0019] Preferably, as an improvement, a limit block is provided at the bottom of the tightening bolt, the limit block is fixedly connected to the piston rod of the cylinder, and the diameter of the limit block is larger than the diameter of the tightening bolt.

[0020] Beneficial effect: The limit block is used to prevent the tensioning bolt from being completely pulled out, thereby preventing the cylinder piston rod from being pulled out and damaging the cylinder, thereby protecting the cylinder.

[0021] Preferably, as an improvement, a "U-shaped" opening passing through the center is provided on the side of the movable pressure plate, and the opening is used to clamp the tightening bolt.

[0022] Beneficial effect: By clamping the "U-shaped" opening with the tightening bolt, the position of the movable pressure plate can be easily and quickly fixed or removed, thereby achieving rapid installation and removal of the product.

[0023] Preferably, as an improvement, the movable pressure plate is shaped like a "shuttle", and the cross-section of the movable pressure plate consists of an isosceles trapezoid with two overlapping bases. Both sides of the movable pressure plate have two isosceles sides connected at an obtuse angle, and the "U-shaped" opening is located at the connection of the two isosceles sides on one side.

[0024] Beneficial effect: The shuttle-shaped design enables the movable pressing plate to have a larger contact surface, which can distribute the pressure more evenly, avoid applying excessive local pressure to the product, and thus reduce damage to the product.

[0025] Preferably, as an improvement, the gap ranges from 0.05 mm to 0.10 mm.

[0026] Beneficial effect: The gap ensures that the product is neither too loose to cause shaking during positioning, nor too tight to cause difficulty in assembly or damage the product, making it easier to load and remove the product and reducing friction resistance during installation and removal.

[0027] Preferably, as an improvement, the front base of the weather vane brake includes a cylindrical shell and an ear seat provided on the shell and protruding radially outward, and the rotating positioning pin presses against the ear seat.

[0028] Beneficial effect: The use of the rotating positioning pin in conjunction with the ear seat can effectively fix the position of the front machine base, ensuring that the product will not shift during processing and improving the stability of the processing process.

[0029] Beneficial effects of the utility model:

[0030] In this case, the processing tooling is used to achieve force balance during product processing, that is, during processing, when the base plate supports the product, it provides an upward force for the product; the cylinder in the clamping mechanism drives the tightening bolt to move from top to bottom, so that when the tightening bolt cooperates to move the pressure plate to clamp the product, it provides a downward force for the product; when the positioning block and the rotating positioning pin in the positioning mechanism are pressed against the ear seat on the product shell for radial positioning, it provides an inward force for the product; when the boss side of the center positioning boss in the positioning mechanism contacts and presses against the inner side of the product, it provides an outward force for the product. The four jointly apply force to the product to achieve force balance, so that the product is evenly stressed during processing, thereby improving the processing quality and stability of the product.

The design of this fixture takes into account the specific structural characteristics, material properties, and processing requirements of the front base of the weathervane brake. This specialized fixture ensures higher precision and efficiency during production, reduces machining errors, and adapts to the needs of mass production. Furthermore, the synergistic effect between the fixture's cylinder, tensioning bolts, and movable pressure plate results in a simple fixture structure and easy operation. This fixture not only helps improve production efficiency but also effectively reduces production costs, ensuring that the quality and performance of the final product meet industry standards and customer requirements.

[0040] The following is further described in detail through specific implementation methods:

[0041] The reference numerals in the drawings of the specification include: base plate 1, tightening bolt 2, movable pressure plate 3, rotating positioning pin 4, center positioning boss 5, positioning block 6, cylinder 7, limit block 8, and processing hole 9.

[0042] Example 1:

[0043] The embodiment is basically as shown in the attached Figure 1 As shown: A front base processing tool for a wind vane brake, including a base plate 1 for supporting the product, a positioning mechanism for circumferentially contacting the product surface and positioning the product, and a pressing mechanism for pressing the product from top to bottom.

[0044] Specifically, such as Figure 1 As shown, the positioning mechanism is installed above the base plate 1, and the positioning mechanism includes a center positioning boss 5. The center positioning boss 5 is fixedly connected to the top surface of the base plate 1. When the product is placed, there is a certain gap between the side of the center positioning boss 5 and the side of the product, and the gap ranges from 0.05mm to 0.10mm. The design of the center positioning boss 5 allows the operator to quickly install the product. At the same time, the reasonable design of the gap will not cause the cylindrical shell to shake due to being too loose, nor will it be difficult to assemble or damage the product due to being too tight, so that the product can be quickly positioned and the product processing operation is simple. In this embodiment, the base plate 1 is a rectangular parallelepiped with equal length and width, the center positioning boss 5 is in the shape of a pancake, and the processed product is a front base for a weather vane brake. The front base for a weather vane brake includes a cylindrical shell and an ear seat that protrudes radially outward on the shell. The length of the movable pressure plate 3 is greater than the inner diameter of the upper end of the front base. When removing and installing the front base, the movable pressure plate must be removed.

[0045] The clamping mechanism is installed above the positioning mechanism and passes through the center of the base plate 1. The clamping mechanism includes a tightening bolt 2 that passes through the center of the base plate 1. The tightening bolt 2 includes an integrally connected screw and a screw head. A detachable movable pressure plate 3 is installed on the upper part of the tightening bolt 2. A "U-shaped" opening passing through the center is provided on the side of the movable pressure plate 3. The opening is used to clamp the screw of the tightening bolt 2. A limit block 8 is welded at the bottom of the tightening bolt 2, and the diameter of the limit block 8 is larger than the diameter of the tightening bolt 2. The bottom of the limit block 8 is connected to the cylinder 7 that drives the tightening bolt 2 to move up and down. The piston rod of the cylinder 7 is fixedly connected to the bottom of the limit block 8. When the cylinder 7 drives the tightening bolt 2 to move downward to press the product, the tightening bolt 2 cooperates with the movable pressure plate 3 to press the product, so that the screw head of the tightening bolt 2 contacts the top surface of the movable pressure plate 3, the bottom surface of the movable pressure plate 3 contacts the upper end surface of the product, the top surface of the base plate 1 contacts the lower end surface of the product, the area where the upper end surface of the product contacts the movable pressure plate 3 is the clamping area, and the area where the upper end surface of the product does not contact the movable pressure plate 3 is the exposed area to be processed.

[0046] The clamping mechanism, the base plate 1 and the positioning mechanism work together on the product surface, and the forces among the three are balanced, so that the product can be accurately positioned while being reliably clamped, thereby improving the stability of product processing.

[0047] like Figure 2As shown, the length of the movable pressure plate 3 is smaller than the diameter of the center positioning boss 5 to ensure that the movable pressure plate 3 can be accurately positioned in the countersunk hole of the product during installation to avoid offset or misalignment; the screw head of the tightening bolt 2 contacts the top surface of the movable pressure plate 3, and the slot width of the movable pressure plate 3 is larger than the screw diameter and smaller than the screw head, so that the movable pressure plate 3 can be better fixed and supported, and the tightening bolt 2 can be better clamped to prevent it from being displaced or loosened when subjected to force.

[0048] The clamping mechanism, the base plate 1 and the positioning mechanism work together on the product surface, and the forces among the three are balanced, so that the product can be accurately positioned while being reliably clamped, thereby improving the stability of product processing.

[0049] like Figure 3 As shown, the height of the tensioning bolt 2 is greater than the total height of the product and the movable platen 3. When the product is placed on the fixture, the bottom surface of the movable platen 3 contacts the upper end surface of the product, and the top surface of the base plate 1 contacts the lower end surface of the product. In other words, the movable platen 3 is located between the product and the tensioning bolt 2. When the movable platen 3 is inserted into the countersunk hole of the product, there is a certain distance between the bottom of the screw head of the tensioning bolt 2 and the top surface of the movable platen 3. This distance provides additional space for product processing, allowing for fine-tuning during installation or adjustment, and facilitating product installation and removal. Figure 4 As shown, when the movable pressing plate 3 presses the product, the movable pressing plate 3 divides the product into two areas: a pressing area and an area to be processed; the area where the upper end surface of the product contacts the movable pressing plate 3 is the pressing area, and the area where the upper end surface of the product does not contact the movable pressing plate 3 is the exposed area to be processed. There are several processing holes 9 in the area to be processed, so that the processing instrument can directly contact the processing holes 9 for processing.

[0050] The specific implementation process of this embodiment is as follows:

[0051] 1. Before machining: Align the product to be machined from the hole end to the center positioning boss 5 of the tooling, ensuring that the product's side faces contact the side faces of the center positioning boss 5. This prevents the product from shifting during machining and ensures the product's circumferential positioning. Then, place the movable pressure plate 3 in the product's countersunk hole and engage it with the tensioning bolt 2. In other words, the movable pressure plate 3 engages the bolt shank of the tensioning bolt 2 and lies below and in contact with it. The tensioning bolt 2 is driven up and down by the cylinder 7, so that the tensioning bolt 2 and the movable pressure plate 3 together compress the product, achieving precise positioning and reliable clamping of the product.

[0052] 2. During processing: Utilize CNC equipment to automatically change tools and position the product accurately to process the end face of the product hole 9. When processing hole 9, the 8-M6 thread bottom hole processing and 4-M8 thread bottom hole processing will be carried out in sequence, and the M6 thread bottom hole will be chamfered. The ф12 through hole processing, the M8 thread bottom hole will be chamfered, and the ф12 through hole will be chamfered. Finally, the M6 and M8 threads will be tapped.

[0053] 3. After processing is completed: the cylinder 7 drives the tensioning bolt 2 away from the product, releasing the clamping of the product, and then removes the movable pressing plate 3 to take out the processed product.

[0054] This solution utilizes CNC equipment and special tooling to process multiple sizes of the same product, thereby improving production efficiency and processing accuracy and saving processing costs.

[0055] The tooling structure in this solution is simple and is used for the precise clamping of single products. It ensures the accuracy and stability of installation through a clamping mechanism, a positioning mechanism and a base plate 1. The center positioning boss 5 on the tooling helps to accurately position the product in the center position, and limits its rotation direction through the positioning parts. The center positioning boss 5 and the positioning parts work together to fix the position in the X and Y directions, achieving circumferential fixed positioning of the product and improving the processing accuracy of the product. One end of the product contacts the top surface of the base plate 1, and the other end contacts the movable pressure plate 3 with a "U-shape". When the piston rod of the cylinder 7 makes a telescopic motion along the Z-axis, it can achieve clamping or distance operation of the product, thereby improving the processing accuracy of the product.

[0056] Example 2:

[0057] The difference between the second embodiment and the first embodiment is that the second embodiment adds a side positioning mechanism. Unlike the first embodiment, which uses a clamping mechanism to clamp and position the product, the side positioning mechanism added in the second embodiment is a positioning member that is used to support the ear seat of the product from the side, thereby achieving radial positioning of the product. Figure 6 As shown, the positioning member is located outside the central positioning boss 5 and is fixedly connected to the top surface of the base plate 1, and is used to radially fix the product to prevent the product from shifting during processing and affecting the processing quality of the product. Figure 5 As shown, the positioning member includes a rotating positioning pin 4 and a positioning block 6. The positioning block 6 has a threaded through hole for the rotating positioning pin 4 to pass through and be threadedly connected. After passing through the threaded through hole, one end of the rotating positioning pin 4 can abut against the ear seat of the product. Rotating the rotating positioning pin 4 can adjust the length of the extended portion of the rotating positioning pin 4. In this embodiment, the positioning block 6 is a rectangular parallelepiped, wherein the height of the rectangular parallelepiped is greater than the length and width.

[0058] Specifically, in this example, the operator rotates the product clockwise to make it close to the rotating locating pin 4. When the tightening bolt 2 presses the product up and down, the rotating locating pin 4 can realize the radial positioning of the product, ensuring that the product can remain stable in the radial direction during processing. Specifically, after the product is placed in the tooling, the position of the positioning block 6 corresponds to the ear seat protruding radially outward on the product shell, and the rotating locating pin 4 that passes through the positioning block 6 and is spirally connected to the threaded through hole plays a key radial positioning role. When one end of the rotating locating pin 4 abuts against the outer side of the product after passing through the threaded through hole, the length of the protruding part of the rotating locating pin 4 can be adjusted by rotating the rotating locating pin 4, preventing any movement or rotation of the product in the radial direction, thereby ensuring that the product is in a fixed position throughout the entire processing process, ensuring the radial position accuracy of the product, and preventing the product from being offset in the radial direction due to the action of external forces.

[0059] Example 3:

[0060] The only difference between the third embodiment and the first embodiment is that Figure 7 、 Figure 8 As shown, the movable pressure plate 3 is in the shape of a "shuttle", and the cross section of the movable pressure plate 3 consists of an isosceles trapezoid with two overlapping bottom edges. Both sides of the movable pressure plate 3 have two isosceles edges connected at an obtuse angle, and the "U-shaped" opening is located at the connection of the two isosceles edges on one side.

[0061] In this embodiment, when in use, first align the "U-shaped" opening with the screw of the tightening bolt 2, and move the movable pressure plate 3 so that the screw of the tightening bolt 2 is in the center position of the movable pressure plate 3, and the top surface of the movable pressure plate 3 contacts the screw head of the tightening bolt 2.

[0062] Specifically, align the "U-shaped" opening of the movable pressure plate 3 with the screw of the tensioning bolt 2, paying attention to the direction and position of the opening so that it can be smoothly engaged with the tensioning bolt 2. Slowly translate the movable pressure plate 3 so that the screw of the tensioning bolt 2 is completely located in the center of the movable pressure plate 3, ensuring that the screw enters the "U-shaped" opening accurately. During the translation process, the movable pressure plate 3 must be kept stable, avoiding any shaking or tilting to avoid affecting its position in the product countersunk hole and affecting its positioning accuracy. When the screw of the tensioning bolt 2 is at the center of the movable pressure plate 3, align it with the engaging position in the product countersunk hole, and then apply slight force to make the movable pressure plate 3 close to the engaging position of the product. The shape design of the movable pressure plate 3 combines the structural characteristics of the product. Through the "shuttle-shaped" design, the movable pressure plate 3 divides the processed product into two areas: the clamping area and the processing area. This ensures that the clamping area and the processing area do not affect each other, allowing the processing of different sizes of the same product, thereby improving its production efficiency. At the same time, a larger contact area is created between the movable pressing plate 3 and the product, which can distribute the pressure more evenly and avoid damage to the product due to excessive local pressure, thereby reducing damage to the product and improving the accuracy and stability of positioning.

[0063] The above description is merely an embodiment of the present invention, and the commonly known specific technical solutions and / or features of the solution are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be considered as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
