Description

Technical Field

[0001] This utility model relates to the field of brake pump processing technology, specifically a special fixture for brake pumps. Background Technology

[0002] The master cylinder, also known as the brake master cylinder, is the core control device of a vehicle's braking system, working in conjunction with the brake wheel cylinders to achieve vehicle braking. Based on their working principle, they are divided into two main categories: pneumatic and hydraulic. The former is mostly used in heavy-duty trucks, engineering vehicles, and other large equipment, while the latter is mainly suitable for small cars and some agricultural vehicles. A pneumatic master cylinder consists of upper / lower chamber pistons, a valve assembly, and a pressure passage. When the brake pedal is depressed, compressed air enters the brake chamber through the intake valve, pushing the diaphragm and driving the cam to apply the brakes. Its improved two-stage point braking master cylinder uses electromagnetic supercharging technology, achieving stable pressure and powerful braking through multi-chamber linkage, making it suitable for various vehicle models. A hydraulic master cylinder, on the other hand, generates hydraulic pressure by squeezing brake fluid with a piston, transferring kinetic energy to the wheel cylinder pistons to drive the brake pads for friction braking. Both types of master cylinders employ a dual-circuit design, performing sensitive follow-up control during braking and release.

[0003] To address the issues of complex workstation structures, large space requirements, and difficulty in operation during the production of brake calipers, a two-station brake caliper fixture has been developed (see patent number: 202120122265.4). Brake calipers are indispensable chassis braking components in the braking system. Their main function is to actuate the brake pads, causing them to rub against the brake drum, thus reducing vehicle speed and bringing the vehicle to a stop. When the brake is applied, the master cylinder generates thrust to pressurize hydraulic oil into the calipers, and the piston inside the calipers moves under hydraulic pressure, pushing the brake pads.

[0004] However, existing brake pump clamps cannot adjust the resistance at the rotating end of the brake pump during the clamping process if rotation is required. If rotation is required, the subsequent grinding and polishing operations will be less stable, thus reducing the utilization rate.

[0005] Therefore, a special clamp for brake pumps is proposed to address the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a special clamp for brake pumps in order to solve the problem of lack of resistance force adjustment function during clamping and rotation.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a special clamp for a brake pump, comprising a base plate, a movable component movably connected to one side of the base plate, and a brake pump body clamped on the top of the side adjacent to the base plate and the movable component.

[0008] The movable component includes a second support frame, with screws and limiting rods respectively provided on both sides of the bottom of the second support frame, an arc-shaped movable frame provided on one side of the top of the second support frame, a movable pressure plate provided at the bottom of the inside of the arc-shaped movable frame, a stud extending to one side of the second support frame provided on one side of the arc-shaped movable frame, a nut threadedly connected to the outside of the stud, and a toggle rod provided at the bottom of the nut;

[0009] The base plate has support plates on both sides of its top. One set of support plates has support rods at both ends of one side of its top. The support rods are connected to a first support frame. An arc-shaped fixing frame is provided at the top of one side of the first support frame. A fixing pressure plate is provided at the bottom of the arc-shaped fixing frame. A first bearing is provided on the other side of the arc-shaped fixing frame.

[0010] As a further embodiment of this utility model: one end of the bottom side of the second support frame is provided with a threaded hole that matches the screw, and the other end of the bottom side of the second support frame is provided with a hole that matches the limiting rod. The screw is threadedly connected to the second support frame through the threaded hole, and the limiting rod is movably connected to the second support frame through the hole.

[0011] As a further improvement of this utility model: a socket is provided on the top of one side of the second support frame, and the stud is movably connected to the second support frame through the socket.

[0012] As a further improvement of this utility model, the arc-shaped fixing frame is rotatably connected to the first support frame via a first bearing.

[0013] As a further embodiment of this utility model: a connecting hole is provided at one end of one side of the remaining set of support plates, and the screw is rotatably connected to the remaining set of support plates through the connecting hole.

[0014] As a further improvement of this utility model: a handle is provided on one side of the screw, and the handle is rotatably connected to the screw via a connecting shaft.

[0015] As a further improvement of this utility model: a second bearing 4 is provided at the bottom of one end of the first support frame, and the first support frame is rotatably connected to the support rod through the second bearing.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By using the screw, movable pressure plate, arc-shaped fixed frame and arc-shaped movable frame, the screw can be rotated and combined with the limiting support of the limiting rod, so that the movable pressure plate can move left and right along the screw and the limiting rod, thereby adjusting the clamping range. The brake pump body can also be rotated 90° for clamping operation on its side, which is convenient for clamping and improves the utilization rate.

[0018] 2. By using the provided nuts, studs, movable pressure plates, arc-shaped fixed brackets, and arc-shaped movable brackets, the length of the stud's extension on the side of the movable pressure plate can be adjusted. The tighter the nut is tightened between the stud and the movable pressure plate, the greater the resistance it experiences; conversely, the looser the nut is tightened, the less resistance it experiences. This allows for resistance adjustment, facilitating subsequent grinding operations and preventing misalignment due to excessive rotation. If the brake pump needs to be rotated, the resistance at the rotating end can be adjusted according to the actual situation. Rotation enhances operational stability during subsequent grinding and polishing operations, thereby improving utilization. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0027] Please see Figures 1-5 In this embodiment of the utility model, a special clamp for a brake pump includes a base plate 1, a movable component 2 is movably connected to one side of the base plate 1, and a brake pump body 3 is clamped on the top of the adjacent side of the base plate 1 and the movable component 2.

[0028] The movable component 2 includes a second support frame 201. A screw 202 and a limiting rod 204 are respectively provided on both sides of the bottom of the second support frame 201. An arc-shaped movable frame 208 is provided on one side of the top of the second support frame 201. A movable pressure plate 209 is provided at the bottom of the inside of the arc-shaped movable frame 208. A stud 205 extending to one side of the second support frame 201 is provided on one side of the arc-shaped movable frame 208. A nut 206 is threadedly connected to the outside of the stud 205. A toggle rod 207 is provided at the bottom of the nut 206.

[0029] Among them, support plates 101 are provided on both sides of the top of the base plate 1. Support rods 102 are provided at both ends of the top of one side of one set of support plates 101. The support rods 102 are connected to the first support frame 103. An arc-shaped fixing frame 105 is provided at the top of one side of the first support frame 103. A fixing pressure plate 106 is provided at the bottom of the arc-shaped fixing frame 105. A first bearing 104 is provided on the other side of the arc-shaped fixing frame 105.

[0030] In this embodiment, bearings are an important component in modern mechanical equipment; their main function is to support rotating mechanical bodies, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. Early linear motion bearings consisted of a row of wooden rods placed under a row of skids. Modern linear motion bearings use the same working principle, except that sometimes balls are used instead of rollers. The simplest rotary bearing is a bushing bearing, which is simply a bushing sandwiched between a wheel and an axle. This design was later replaced by rolling bearings, which use many cylindrical rollers instead of the original bushing, with each rolling element acting like an individual wheel.

[0031] like Figures 1 to 5 As shown, one end of the bottom side of the second support frame 201 is provided with a threaded hole that matches the screw 202, and the other end of the bottom side of the second support frame 201 is provided with a hole that matches the limiting rod 204. The screw 202 is threadedly connected to the second support frame 201 through the threaded hole, and the limiting rod 204 is movably connected to the second support frame 201 through the hole.

[0032] In this embodiment, the screw 202 is a cylinder with helical grooves cut on its outer surface or a cone with conical helical grooves cut on its outer surface. The screw 202 has different heads, which are called external hexagonal screws. As can be seen from the extrusion process, the screw 202 works under high temperature, certain corrosion, strong wear, and high torque. Therefore, the screw 202 must: 1) be resistant to high temperature and not deform at high temperature; 2) be wear-resistant and have a long service life; 3) be corrosion-resistant as the material is corrosive; 4) have high strength and can withstand high torque and high speed; 5) have good machinability; 6) have low residual stress and small thermal deformation after heat treatment, etc.

[0033] like Figures 1 to 5 As shown, a socket is provided on the top of one side of the second support frame 201, and the stud 205 is movably connected to the second support frame 201 through the socket.

[0034] In this embodiment, the second support frame 201 is a key temporary facility in concrete pouring construction, consisting of uprights, horizontal bars, and connectors forming a spatial stability system. The main types include steel frame systems such as coupler type, cup-lock type, and disc-lock type, with adjustable bases allowing for height adjustment from 0-30cm, adapting to construction needs in complex terrain conditions such as ditches and ravines. Its foundation treatment requires the installation of 150mm×150mm×6mm steel plate pads. When the support height exceeds 8 meters, it requires layered backfilling and compaction of the foundation soil followed by the pouring of a concrete cushion layer. For safety protection, it is stipulated that for heights exceeding 5 meters, fixed points must be installed, and continuous scissor bracing (angle 45°-60°) must be configured to enhance overall stability.

[0035] like Figures 1 to 5 As shown, the arc-shaped fixing frame 105 is rotatably connected to the first support frame 103 via the first bearing 104.

[0036] like Figures 1 to 5 As shown, a connecting hole is provided at one end of one side of the remaining set of support plates 101, and the screw 202 is rotatably connected to the remaining set of support plates 101 through the connecting hole.

[0037] like Figures 1 to 5 As shown, a handle 203 is provided on one side of the screw 202, and the handle 203 is rotatably connected to the screw 202 through a connecting shaft.

[0038] In this embodiment, a handle refers to a pull handle or a handshake; a part of an object that is held by the hand; a mechanical part; a handle is commonly known as a bakelite handle, a knob, etc.; the handle is made of PF phenolic plastic (bakelite) material and is formed by heat-pressing, with standard colors of black and bright red; the handle has two installation methods: internal thread hole (nut type) and external thread (exposed bolt); bakelite handles have good insulation performance, a bright surface, are corrosion-resistant, abrasion-resistant, have high mechanical hardness, are non-toxic, and are suitable for various mechanical parts.

[0039] like Figures 1 to 5 As shown, a second bearing 4 is provided at the bottom of one end of the first support frame 103, and the first support frame 103 is rotatably connected to the support rod 102 through the second bearing 4.

[0040] Working principle: When in use, first turn the handle 203 to make the handle 203 rotate the screw 202. Since the screw 202 is rotatably connected to the second support frame 201 through the threaded hole, and under the limiting action of the limiting rod 204, the second support frame 201 moves left and right along the screw 202, so that the distance between the first support frame 103 and the second support frame 201 can be adjusted. When the distance of the handle 203 is shortened to a certain extent, the brake pump body 3 is clamped between the arc-shaped fixed frame 105 and the arc-shaped movable frame 208, and directly contacts the fixed pressure plate 106 and the movable pressure plate 209. Continuously rotating the screw 202 can make the first support frame 103 and the second support frame 201 squeeze the brake pump body 3 to achieve installation. When it is necessary to rotate the brake pump body 3, the brake pump body 3 can be manually turned directly downwards.

[0041] When it is necessary to adjust the resistance generated during rotation, the lever 207 can be moved directly along the stud 205, causing the lever 207 to rotate along the external thread of the stud 205 with the nut 206. This brings the distance between the nut 206 and the second support frame 201 closer and closer, thereby tightening the arc-shaped movable frame 208 and making the distance between the arc-shaped movable frame 208 and the second support frame 201 even tighter. By slightly adjusting the position of the second support frame 201 on the screw 202, the distance between the first support frame 103 and the second support frame 201 can be adjusted. After adjusting the distance between the first support frame 103 and the second support frame 201, the resistance generated by the rotation of the brake pump body 3 can be adjusted.

[0042] The rotatable connection between the stud 205 and the second support frame 201 is achieved by the lateral compression of the second support frame 201 by the nut 206. Thus, the damping and frictional resistance can be adjusted by utilizing the compression gap reserved between the stud 205, the second support frame 201 and the nut 206, thereby adjusting its degree of movement.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
