Description

Technical Field

[0001] The utility model relates to the technical field of shock absorber bracket opening, in particular to a shock absorber bracket opening device. Background Art

[0002] In order to make the bracket easily inserted when the customer assembles the shock absorber, the shock absorber factory needs to control the size of the shock absorber bracket opening (enlarge or reduce). The current method is to use rectangular blocks of different specifications to directly press them in through a press, such as Figure 2 As shown, the wedge principle is applied, that is, the longitudinal section of the pressure block is a trapezoid or a triangle. A press is used to apply pressure on its back. The effect of the pressure is to form two thrusts on the two side slopes of the wedge. When the pressure block moves downward and the slope contacts the inner edge of the bracket opening, the pressure block continues to move and squeezes the bracket until the pressure block is completely inserted. At this time, the bracket will be expanded to the same width as the pressure block.

[0003] In practice, it is found that this method may cause scratches. The current technology uses a wedge to directly expand the bracket opening. According to the wedge principle, the larger the contact area between the wedge and the slider, the higher the force transmission efficiency. Since the contact area is small during contact, the force transmission efficiency is poor. Most of the force is still downward force and friction. These forces are borne by the inner edge of the bracket. Therefore, scratches or scratches often occur during the processing, which may be deep or shallow depending on the actual situation. The presence of scratches and wounds will affect the return rate.

[0004] There are also problems such as time-consuming model change and tooling maintenance. One specification can only be expanded to the corresponding width. Each model change requires the replacement of the pressing block and readjustment of the positioning, which increases the time consumption. The pressing block is in direct contact with the corners of the workpiece and is easily worn. When the product is severely scratched, the pressing block needs to be maintained and polished before it can be reused, which is time-consuming and laborious. In addition, it is laborious for employees to operate. Since the bracket will rebound after expansion, the pressing block used is often one specification larger than the required size. Therefore, after the pressing block is pressed into the opening of the bracket, it is easy to get stuck and cannot be smoothly withdrawn. After the press rises, the employee needs to take out the product. The employee's operation is laborious and the work efficiency is low. In response to the above defects, this application is proposed. Utility Model Content

[0005] The utility model aims to provide a shock absorber bracket opening device, which increases the contact area between the workpiece and the contact part of the tooling, changes the force structure and force direction, reduces the influence of sliding friction, and achieves the purpose of protecting the workpiece and improving efficiency during processing.

[0006] In order to solve the above problems, the utility model provides a shock absorber bracket opening device, including a fixed plate, a telescopic assembly and a movable block, the telescopic assembly and the movable block are each provided with two groups, the two groups of the telescopic assemblies are installed on the fixed plate, the two groups of the telescopic assemblies are symmetrically arranged, the movable block is connected to the telescopic assembly, and an opening flat plate portion and a force-bearing inclined surface portion are provided on the movable block. When the wedge block is pressed downward, the force-bearing inclined surface portion is stressed, and the two opening flat plate portions are separated from each other. When the downward pressure of the wedge block is removed, the telescopic assembly can automatically retract.

[0007] According to an embodiment of the utility model, the shock absorber bracket opening device also includes a bottom plate, the fixing plate is mounted on the bottom plate, and the bottom plate is used to be connected to the work surface.

[0008] According to an embodiment of the utility model, a positioning block is installed on the bottom plate.

[0009] According to an embodiment of the utility model, the positioning block is detachable.

[0010] According to an embodiment of the utility model, a positioning pin hole is provided on the bottom of the positioning block, and a positioning pin is provided on the bottom plate.

[0011] According to an embodiment of the utility model, the fixing plate is connected to the angle bracket.

[0012] According to an embodiment of the utility model, the shock absorber bracket opening device also includes a wedge block pressing mechanism.

[0013] According to an embodiment of the utility model, the telescopic assembly includes a ball sleeve, a shaft and a spring.

[0014] The beneficial effect of the utility model is that by providing a movable block and an open flat plate portion, the contact area is increased to obtain better force transmission efficiency. At the same time, the increase in the contact area also makes the force on the workpiece surface more even, which greatly reduces the occurrence rate of scratches. The open flat plate portion and the bracket are subjected to vertical force, which greatly reduces the sliding friction and the possibility of scratching the workpiece. After the wedge-shaped pressure block rises, the movable block automatically retracts to the smallest state, and employees can easily remove the workpiece, improving processing efficiency. In addition, because the structure can convert the vertical downward pressure of the press into the horizontal opening and closing amount, employees can adjust in real time and no longer need to replace different pressure blocks, which greatly saves time. Originally, it was necessary to use pressure blocks of various specifications. After the application of this technology, only one set of tooling is needed to apply to most products, saving manufacturing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 2 It is a schematic diagram of the structure of the original bracket opening device. DETAILED DESCRIPTION

[0018] The following description is only used to disclose the utility model so that those skilled in the art can implement the utility model. The embodiments described below are only for example, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other solutions that do not deviate from the spirit and scope of the utility model.

[0019] A shock absorber bracket opening device, such as Figure 1 , including a fixed plate 2, a telescopic component 5 and a movable block 6. The telescopic component 5 and the movable block 6 are each provided with two groups. The two groups of telescopic components 5 are installed on the fixed plate 2. The two groups of telescopic components 5 are symmetrically arranged. The movable block 6 is connected to the telescopic component 5. The movable block 6 is provided with an open flat plate portion 61 and a force-bearing inclined surface portion 62. When the wedge block is pressed down, the force-bearing inclined surface portion 62 is stressed, and the two open flat plate portions 61 are separated from each other. When the downward pressure of the wedge block is removed, the telescopic component 5 can automatically retract.

[0020] The shock absorber bracket opening device also includes a bottom plate 1, a fixing plate 2 is mounted on the bottom plate 1, and the bottom plate 1 is used to be connected to a work surface.

[0021] A positioning block 4 is installed on the base plate 1 .

[0022] The positioning block 4 is detachably arranged.

[0023] A positioning pin hole is provided at the bottom of the positioning block 4 , and a positioning pin is provided on the bottom plate 1 .

[0024] The fixing plate 2 is connected with the angle code 3 .

[0025] The shock absorber bracket opening device also includes a wedge block pressing mechanism, such as a hydraulic press or other device that can drive the wedge block to descend and apply pressure.

[0026] The telescopic component 5 can be a cylinder, a spring, a resettable guide rail or a ball guide column. In this embodiment, a ball guide column is used, which includes a ball sleeve, a shaft and a spring. The shaft is installed in the ball sleeve, the spring is arranged in the ball sleeve and connected to the shaft, and the outer end of the shaft is connected to the movable block 6.

[0027] Optionally, the two movable blocks 6 are in contact with each other when not pressed down by the wedge block 7, ensuring that the total thickness of the two open flat plate portions 61 is small, which is convenient for placing and removing the bracket during processing. Another embodiment, different from the above embodiment, is that a gasket installation hole is provided on the surface of the open flat plate portion 61, and the thickness can be adjusted by installing a gasket, and the gasket can be replaced after wear.

[0028] Specifically, the base plate 1 is the basic part of the structure, connecting and supporting various parts of the structure. It is fixed to the work surface of the hydraulic press by fasteners composed of T-nuts, screws and pressure blocks. The fixed plate 2 is connected to the base plate 1 by threads to form an overall structural frame, with holes and threads for installing ball guide pillars. The angle code 3 connects the fixed plate 2 and the base plate 1 by threads, which plays a role in strengthening the fixation and at the same time bears the pressure release. The positioning block 4 is a quickly replaceable part, which is installed on the two positioning pins of the base plate 1 through the positioning pin holes. It can be replaced as needed. Its main function is to provide support and positioning for the workpiece. The ball guide pillar is fixed on the fixed plate 2, and one or two are set on each of the left and right fixed plates. The ball guide pillar has the functions of fixing, guiding and rebounding and resetting. The movable block 6 is screwed on the ball guide column to form the core part, realizing the function of changing the direction of movement. At the same time, the open flat plate part 61 and the force-bearing inclined surface part 62 of the movable block 6 are in contact with the surface of the workpiece and the wedge block, and the force is balanced. The wedge block 7 is fixed on the hydraulic press head 8. When the press starts and presses down, the inclined surface of the wedge block 7 contacts the force-bearing inclined surface part 62 to squeeze and stretch it open, the spring in the ball guide column shaft is compressed, and the open flat plate part 61 expands the bracket. The open flat plate part 61 and the bracket are vertically stressed, which greatly reduces the sliding friction and reduces the possibility of scratching the workpiece. When the press is raised, the spring in the ball guide column releases the pressure to make the movable block 6 rebound to its original position, and the product can be easily taken out, achieving the effect of improving processing efficiency.

[0029] The wedge structure movement principle is applied to the linear motion hydraulic press to convert the force into horizontal opening and closing motion to meet the production needs of the shock absorber factory.

[0030] The structure changes the force form and the force-bearing subject so as to achieve the purpose of protecting the workpiece during processing.

[0031] The contact area is increased to obtain better force transmission efficiency. At the same time, the increase in contact area also makes the force on the workpiece surface more even, which greatly reduces the occurrence rate of scratches. Originally, due to the influence of sliding friction, the product was prone to scratches with the pressure block during movement. In this technical solution, the change in the movement mode means that the workpiece and the tooling no longer produce large friction, avoiding large-area scratches on the workpiece surface, improving the pass rate and increasing the service life of the tooling. After processing with the original device, the workpiece will be stuck on the pressure block. In this technology, the wedge-shaped pressure block does not directly contact the product. After the wedge-shaped pressure block rises, the movable block automatically retracts to the smallest state, and the employee can easily remove the workpiece; in addition, because the structure can convert the vertical downward pressure of the press into the horizontal opening and closing amount, the employee can adjust in real time and no longer needs to replace different pressure blocks, which greatly saves time. Originally, it was necessary to use pressure blocks of various specifications. After the application of this technology, only one set of tooling is needed to apply to most products, saving manufacturing costs.

[0032] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Without departing from the principles, the embodiments of the present invention may be deformed and modified in any way.
