Description

Technical Field

[0001] This utility model relates to the field of tooling technology, specifically to a multi-station clamping tool. Background Technology

[0002] The master cylinder is a key component of a car's braking system. When the driver presses the brake pedal, the master cylinder converts the mechanical force input from the pedal into the pressure energy of the brake fluid. This pressure is then transmitted through the brake lines to the brake calipers. The pistons in the brake calipers, under pressure, push the brake pads, causing them to come into close contact with the brake disc or brake drum, generating friction. This friction impedes the rotation of the wheels, achieving the purpose of slowing down or stopping the vehicle. After the master cylinder block is cast, it needs to be clamped with tooling and then milled or bored. Because the cylinder block has multiple machined surfaces, the positioning reference needs to be re-established each time a machined surface is changed, which affects machining accuracy and efficiency. Utility Model Content

[0003] This invention proposes a multi-station clamping fixture, which solves the problem in related technologies where the cylinder body has multiple machining surfaces, and the positioning reference needs to be re-determined every time the machining surface is changed, which affects the machining accuracy and efficiency.

[0004] The technical solution of this utility model is as follows: A multi-station clamping fixture for clamping cylinder bodies, the key feature being: comprising,

[0005] Base

[0006] The support frame is provided at both ends of the base;

[0007] A turntable, which is rotatably mounted on the support frame;

[0008] A locking element is disposed on the turntable, and the cylinder is used to lock between the locking elements at both ends;

[0009] A machining surface indicator is provided on the circumferential surface of at least one of the turntables, and the number of machining surface indicators is multiple, with all the machining surface indicators evenly arranged along the circumferential surface of the turntable;

[0010] A positioning component is provided, which is raised and lowered on the base and located below the machining surface indicator. The upper end face of the positioning component has a slot. After the positioning component is raised, the machining surface indicator is used to insert into the slot.

[0011] Furthermore, it also includes a guide sleeve, which is disposed on the support frame and fitted around the positioning member, and the positioning member is slidably connected to the guide sleeve.

[0012] Furthermore, it also includes an elastic reset member, the lower end of which is connected to the base, and the upper end of which is connected to the positioning member.

[0013] Furthermore, it also includes a limiting sleeve, which is disposed on the base and located around the elastic reset member.

[0014] Furthermore, the limiting sleeve is threadedly connected to the base, the elastic reset member is detachably connected to the base, and the elastic reset member is detachably connected to the positioning member.

[0015] Furthermore, the turntable located at one end of the base is provided with the processing surface indicator and also includes a tightening screw. The tightening screw is threadedly connected to the support frame located at the other end of the base and is located on the outside of the turntable at that end, for tightening the turntable at that end.

[0016] Furthermore, it also includes an operating handle, which is connected to the end of the tightening screw away from the turntable.

[0017] Furthermore, it also includes a lead screw, which is rotatably mounted on the base and threadedly connected to the support frame at one end of the base. After the lead screw rotates, the support frame at that end is used to move closer to or further away from the support frame at the other end of the base.

[0018] Furthermore, the operating handle is detachably connected to the tightening screw, and the operating handle is detachably connected to the lead screw.

[0019] Furthermore, it also includes wheels, which are rotatably mounted below the base.

[0020] The working principle and beneficial effects of this utility model are as follows: support frames are provided at both ends of the base; the turntable is rotatably mounted on the support frames; locking components are mounted on the turntable, and the cylinder is used to lock between the locking components at both ends; a processing surface indicator is provided on the circumferential surface of at least one turntable, and the number of processing surface indicators is multiple, with all processing surface indicators evenly arranged along the circumferential surface of the turntable; a positioning component is lifted and mounted on the base, and located below the processing surface indicator; the upper end face of the positioning component has a slot, and after the positioning component rises, the processing surface indicator is used to insert into the slot.

[0021] Both ends of the base are rotatably connected to turntables, each equipped with locking mechanisms. Machining surface indicators on the circumference of the turntables correspond one-to-one with the surfaces to be machined. When processing the cylinder, it is clamped between the two locking mechanisms, and one machining surface indicator engages with a slot on the upper surface of a positioning element, ensuring that one surface of the cylinder is in the desired position. After processing that surface, the positioning element is lowered, disengaging the machining surface indicator from its slot. The turntable is then rotated, causing the locking mechanisms and cylinder to rotate synchronously. The positioning element rises, and the next machining surface indicator engages with its slot, ensuring the next surface of the cylinder is in the desired position. This eliminates the need for repeated disassembly and reassembly of the cylinder. Only the positioning reference needs to be established when clamping the cylinder. Subsequent changes to the surface to be machined only require rotating the turntable, without needing to re-establish the positioning reference, thus improving processing accuracy and efficiency.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] Example, refer to Figures 1-3 As an embodiment of this utility model, a multi-station clamping fixture is proposed for clamping a cylinder body 15. It includes a base 1, a support frame 2, a turntable 3, a locking member 4, a machining surface indicator 5, and a positioning member 6. Support frames 2 are provided at both ends of the base 1. The turntable 3 is rotatably mounted on the support frame 2. The locking member 4 is mounted on the turntable 3, and the cylinder body 15 is used to lock between the locking members 4 at both ends. Machining surface indicator 5 is provided on the circumferential surface of at least one turntable 3. There are multiple machining surface indicator 5s, and all machining surface indicator 5s are arranged along the circumferential surface of the turntable 3. The positioning member 6 is raised and lowered on the base 1 and located below the machining surface indicator 5. The upper end surface of the positioning member 6 has a slot 7. After the positioning member 6 is raised, the machining surface indicator 5 is used to insert into the slot 7.

[0033] In this embodiment, turntables 3 are rotatably connected to the support frames 2 at both ends of the base 1. Locking elements 4 are provided on both turntables 3. The processing surface indicator 5 on the circumference of the turntable 3 is set one-to-one with the surface to be processed. When the cylinder 15 needs to be processed, the cylinder 15 is clamped between the two locking elements 4. One processing surface indicator 5 is inserted into the slot 7 on the upper end face of the positioning element 6 to ensure that one surface to be processed of the cylinder 15 is in the required position. After processing the surface to be processed, the positioning element 6 is lowered, and the processing surface indicator 5 is separated from the slot 7 on the upper end face of the positioning element 6. Then the turntable 3 is rotated, and the turntable 3 drives the locking elements 4 and the cylinder 15 to rotate synchronously. The positioning element 6 rises, and the next processing surface indicator 5 is inserted into the slot 7 on the upper end face of the positioning element 6 to ensure that the next surface to be processed of the cylinder 15 is in the required position. There is no need to repeatedly disassemble and assemble the cylinder body 15. Only the positioning reference needs to be determined when clamping the cylinder body 15. When changing the surface to be machined, only the turntable 3 needs to be rotated. There is no need to re-determine the positioning reference, which can improve machining accuracy and machining efficiency.

[0034] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, it also includes a guide sleeve 8, which is mounted on the support frame 2 and fitted around the positioning member 6. The positioning member 6 and the guide sleeve 8 are slidably connected.

[0035] When the positioning element 6 rises or falls on the base 1, the guide sleeve 8, through the contact between its inner wall and the outer wall of the positioning element 6, ensures that the positioning element 6 can only move along the axial direction defined by the guide sleeve 8. This avoids offset and shaking caused by external forces or instability of its own structure, further improving the accuracy and stability of the positioning element 6's movement. It also ensures that each time the positioning element 6 rises, the slot 7 on its upper surface accurately engages with the machining surface indicator 5. There are at least two guide sleeves 8, all arranged vertically. The combined action of multiple guide sleeves 8 provides better guiding and limiting effects.

[0036] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, it also includes an elastic reset member 9, the lower end of which is connected to the base 1, and the upper end of which is connected to the positioning member 6.

[0037] The elastic reset component 9 typically uses a spring or other element with elastic deformation characteristics. Based on the principles of elastic potential energy and elastic force, when the positioning component 6 is lowered by overcoming the elastic force under the action of external force, the elastic reset component 9 is compressed and stores elastic potential energy. Once the external force disappears, the elastic reset component 9 releases the elastic potential energy, generating an upward elastic force to push the positioning component 6 back to its initial position. This simplifies the operation process, eliminates the need for operators to manually and precisely reset the positioning component 6, saves operation time, and improves work efficiency.

[0038] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, it also includes a limiting sleeve 10, which is disposed on the base 1 and located around the elastic reset member 9.

[0039] As a protective and limiting structure, the limiting sleeve 10 limits the radial expansion range of the elastic reset member 9, preventing the elastic reset member 9 from tilting, twisting, or falling out of the base 1 due to uneven force or excessive deformation during compression or rebound. This ensures that it works stably within the predetermined space, enhances the reliability and stability of the elastic reset member 9, extends its service life, and thus ensures the stability of the entire tooling system. It also reduces problems such as inaccurate positioning and processing interruption caused by the failure of the elastic reset member 9, ensuring smooth processing and improving production efficiency.

[0040] Furthermore, the limiting sleeve 10 is threadedly connected to the base 1, the elastic reset member 9 is detachably connected to the base 1, and the elastic reset member 9 is detachably connected to the positioning member 6.

[0041] The removable connection between the elastic reset component 9 and the base 1 and the positioning component 6, such as by using hooks, slots or nuts, allows the limit sleeve 10 to be easily installed and removed from the base 1 when the elastic reset component 9 is damaged, aged or needs to be replaced with a component with a different elastic coefficient. This facilitates the maintenance and replacement of the elastic reset component 9 inside the base 1, improves the maintainability of the tooling, and reduces maintenance costs and time.

[0042] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, a machining surface indicator 5 is provided on the turntable 3 at one end of the base 1, and a tightening screw 11 is also provided. The tightening screw 11 is threadedly connected to the support frame 2 located at the other end of the base 1 and is located on the outside of the turntable 3 at that end, for tightening the turntable 3 at that end.

[0043] Taking a turntable 3 located at the rear end of the base 1 with a machining surface indicator 5 as an example, the tightening screw 11 is threadedly connected to the front support frame 2. When the cylinder body 15 needs to be installed, the rear end of the tightening screw 11 is separated from the front turntable 3. After locking the cylinder body 15 with the locking member 4, the tightening screw 11 is rotated so that the rear end of the tightening screw 11 is in close contact with the turntable 3 located at the front end of the base 1, so that the turntable 3 and the cylinder body 15 can be firmly locked in the current position. When it is necessary to change the machining surface, first separate the tightening screw 11 from the turntable 3, and then move down the positioning member 6 located at the rear end of the base 1 to separate the machining surface indicator 5 from the positioning member 6. It is not necessary to operate the front and rear positioning members 6 at the same time, making the operation simpler and more convenient.

[0044] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, it also includes an operating handle 12, which is connected to the end of the tightening screw 11 away from the turntable 3.

[0045] The L-shaped operating handle 12 serves as a force transmission tool, allowing operators to more easily rotate the tightening screw 11, overcome the friction between the threads, and effectively tighten the turntable 3. This improves the convenience and comfort of operation, reduces the labor intensity of operators, and enables the tightening operation to be completed quickly and accurately. It also reduces problems such as insufficient or excessive tightening caused by inconvenient operation, ensuring the stable fixation of the turntable 3.

[0046] Furthermore, such as Figure 1 and Figure 2 As shown, it also includes a lead screw 13, which is rotatably mounted on the base 1 and threadedly connected to the support frame 2 at one end of the base 1. After the lead screw 13 rotates, the support frame 2 at that end is used to move closer to or further away from the support frame 2 at the other end of the base 1.

[0047] Taking the threaded connection between the lead screw 13 and the front support frame 2 as an example, when the lead screw 13 rotates, the support frame 2 threadedly connected to it will move along the axial direction of the lead screw 13, so that the front support frame 2 moves closer to or further away from the rear support frame 2, thereby achieving precise adjustment of the distance between the two support frames 2. It can flexibly clamp cylinders 15 of various sizes, eliminating the need to equip multiple sets of tooling for cylinders 15 of different specifications, reducing production costs, improving the utilization rate of production equipment, and meeting diverse production needs.

[0048] Furthermore, the operating handle 12 is detachably connected to the tightening screw 11, and the operating handle 12 is detachably connected to the lead screw 13.

[0049] The operating handle 12 is designed with detachable connections, such as plug-in or snap-fit ​​connections, allowing for easy switching between the tightening screw 11 and the lead screw 13. Operators can install the operating handle 12 onto the component requiring rotation, flexibly applying torque using the handle 12 according to actual operational needs.

[0050] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it also includes a traveling wheel 14, which is rotatably mounted below the base 1.

[0051] Two left and two right traveling wheels 14 are simultaneously installed at both the front and rear ends of the base 1. The axes of the four traveling wheels 14 are arranged along the left and right direction. The traveling wheels 14 utilize the principle of rolling friction to transform the sliding friction between the tooling and the ground into rolling friction. When the tooling needs to be moved, only a small horizontal thrust needs to be applied, and the traveling wheels 14 will rotate, driving the tooling to move easily. This can improve the mobility and portability of the tooling, facilitate the transfer of tooling between different workstations in the workshop, adapt to adjustments in the production layout, reduce the manpower and time costs required for handling tooling, improve the logistics efficiency of the production site, and provide convenient conditions for efficient production.

[0052] 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.
