Description

Technical Field

[0001] The utility model relates to the technical field of leaf spring processing, and particularly relates to a clamping device for leaf spring processing. Background Art

[0002] A leaf spring, also called a plate spring, is a widely used elastic element in an automobile suspension. It is an approximately equal-strength elastic beam composed of several alloy spring leaves with the same width but different lengths. The leaf spring has a simple structure, reliable operation, low cost, and convenient maintenance. It is both an elastic element of the suspension and a guiding device of the suspension. One end of it is hinged to the vehicle frame, which can transmit various forces and torques and determine the jumping trajectory of the wheel. At the same time, it also has a certain friction damping effect and is widely used in non-independent suspensions.

[0003] Currently, during the processing of leaf springs, various clamping devices are needed to clamp and fix them. For example, the Chinese utility model patent with the patent number 202321468403.X provides a leaf spring hanger milling machine for automobiles. This device drives a left-handed and right-handed threaded lead screw to rotate in a threaded groove through a turning handle, thereby driving two sliders to move relatively in a slideway. The relative movement of the two sliders drives two clamping plates to move relatively on a workbench, so as to apply a clamping force to both ends of the leaf spring in the processing area to clamp and fix the leaf spring.

[0004] However, most of the existing clamping devices for leaf spring processing clamp the leaf spring by applying an inward clamping force to both ends of it, which easily causes the arc of the leaf spring to change during the processing, thereby affecting the quality of the leaf spring. Therefore, in view of this, a clamping device for leaf spring processing is proposed to solve the above technical problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the utility model proposes a clamping device for leaf spring processing to solve the technical problem proposed in the above background art, that is, most of the existing clamping devices for leaf spring processing clamp the leaf spring by applying an inward clamping force to both ends of it, which easily causes the arc of the leaf spring to change during the processing, thereby affecting the quality of the leaf spring.

[0006] To achieve the above purpose, the utility model provides the following technical solutions. A clamping device for leaf spring processing includes:

[0007] A base;

[0008] Two sliding seats, which are respectively slidably arranged on the base;

[0009] An adjusting mechanism, which is arranged on the base and connected to the two sliding seats to drive the two sliding seats to slide in the opposite direction; and

[0010] There are three sets of clamping components, one of which is fixedly arranged on the base, and the other two sets of clamping components are respectively rotatably arranged on the two sliding seats.

[0011] In a preferred embodiment, a fixing groove is formed on the base.

[0012] In a preferred embodiment, a positioning hole is formed on the base.

[0013] In a preferred embodiment, the adjusting mechanism includes:

[0014] A bidirectional lead screw, which is rotatably arranged on the base along its axis;

[0015] Two sets of threaded seats, which are respectively fixedly arranged on the two sliding seats, and the two threaded seats are respectively screwed on the two ends of the bidirectional lead screw; and

[0016] A rotating part, which is arranged at the end of the bidirectional lead screw.

[0017] In a preferred embodiment, the clamping component includes:

[0018] A clamping base, two of which are rotatably arranged on the sliding seat, and the other clamping base is fixedly arranged on the base;

[0019] A clamping plate, which is arranged on the clamping base in a liftable manner and cooperates with it to form an opening for accommodating a leaf spring. A connecting frame is arranged on the clamping plate; and

[0020] A threaded knob, the end of which is rotatably screwed with the clamping base and screwed with the connecting frame.

[0021] In a preferred embodiment, a detachable first arc plate is arranged on the clamping base, and a second arc plate opposite to the first arc plate is detachably arranged at the bottom of the clamping plate.

[0022] In a preferred embodiment, a first limiting block is arranged at the end of the first arc plate, and a second limiting block is arranged at the end of the second arc plate on the side opposite to the first arc plate.

[0023] Compared with the prior art, the present utility model has the following beneficial effects:

[0024] When in use, the clamping device can install the base in the processing area for use, which facilitates the processing of each process of the leaf spring, improves the applicable range of the clamping device. During the clamping process, place the leaf spring on one side of the base, clamp the middle section of the leaf spring through a set of clamping components in the middle, and adjust the distance between the two sliding seats through the adjustment mechanism to adjust the distance between the other two sets of clamping components. Then rotate the clamping components on the sliding seats so that the clamping gap can adapt to the arc of the leaf spring. Finally, clamp the other two sets of clamping components at both ends of the leaf spring. Clamping and processing the leaf spring through this device can be applicable to leaf springs with different arcs. Compared with traditional clamping devices, it will not apply an inward clamping force to both ends of the leaf spring, effectively preventing the arc of the leaf spring from changing during the processing of the leaf spring and improving the quality of leaf spring production.

[0034] The present invention will be further described in detail below with reference to the drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present invention and cannot be understood as limiting the protection scope of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention according to the above application content.

[0035] Embodiment:

[0036] As Figure 1 shown, the present utility model provides a clamping device for leaf spring processing, including a base 101. Fixed slots 102 and positioning holes 103 are provided on the base 101. During use, the base 101 can be placed on the processing area or processing equipment, and the base 101 is fixed through bolts in cooperation with the fixed slots 102. Positioning posts can also be added to the processing area or processing equipment, and the position of the base 101 can be positioned through the cooperation of the positioning posts and the positioning holes 103 during the installation process.

[0037] As Figure 1 shown, in this embodiment, two groups of sliding seats 201 are slidably arranged on the base 101, and an adjusting mechanism connected to the two groups of sliding seats 201 is arranged on the base 101. The two groups of sliding seats 201 are driven to slide in opposite directions through the adjusting mechanism. The adjusting mechanism includes a bidirectional lead screw 104 rotatably arranged on the base 101. Threaded seats 202 are arranged on both groups of sliding seats 201, and the two groups of threaded seats 202 are respectively screwed on both ends of the bidirectional lead screw 104. A rotating part 105 is arranged at the bottom of the bidirectional lead screw 104.

[0038] The rotating part 105 can be driven by a motor or manually to drive the bidirectional lead screw 104 to rotate. During the rotation of the bidirectional lead screw 104, the two groups of threaded seats 202 are driven to rotate in opposite directions through the threads in opposite directions, so that the two groups of sliding seats 201 move in opposite directions to adjust the distance between the two groups of sliding seats 201.

[0039] As Figure 1 、 3 shown, in this embodiment, rotatable clamping components are arranged on both groups of sliding seats 201, and a group of clamping components is fixedly arranged on the base 101. The clamping components include clamping bases 301. Among them, the two groups of clamping bases 301 are rotatably arranged on the sliding seats 201, and the other group of clamping bases 301 is fixedly arranged on the base 101. A clamping plate 302 is arranged on the clamping base 301 in a liftable manner. The clamping plate 302 and the clamping base 301 cooperate to form an opening for accommodating the leaf spring. A connecting frame 303 is arranged on the clamping plate 302, and a thread knob 304 rotatably installed is arranged on the clamping base 301. The thread knob 304 is screwed with the connecting frame 303.

[0040] When adjusting the distance between the two sets of sliding seats 201 through the adjusting mechanism, the distance between the two sets of clamping components can be adjusted. Moreover, the clamping bases 301 in the two sets of clamping components are rotatably arranged on the sliding seats 201, so that the clamping openings of the three sets of clamping components can adapt to leaf springs with different arcs. Clamp the middle section of the leaf spring through a set of clamping components fixedly arranged on the base 101, and clamp the two ends through the other two sets of clamping components. By rotating the threaded knob 304, the clamping plate 302 can be moved to close with the clamping base 301, and the leaf spring to be processed is clamped in this way, without applying force to the end of the leaf spring, thus effectively preventing the arc of the leaf spring from changing during the processing.

[0041] As Figure 2 , 3 shown, in this embodiment, a detachable first arc plate 401 is arranged on the clamping base 301, and a second arc plate 403 opposite to the first arc plate 401 is detachably arranged at the bottom of the clamping plate 302. A first limiting block 402 is arranged at the end of the first arc plate 401, and a second limiting block 404 is arranged at the end of the second arc plate 403 on the side opposite to the first arc plate 401.

[0042] During use, different sizes of the first arc plate 401 and the second arc plate 403 can also be selected according to the arc of the leaf spring for use, so that the clamping component can form a surface contact with the leaf spring and improve the clamping effect. And after the clamping plate 302 and the clamping base 301 are closed, the position of the leaf spring can be limited by the first limiting block 402 and the second limiting block 404, avoiding the leaf spring from sliding out of the clamping component and improving the clamping stability of the leaf spring.

[0043] Specific usage method and beneficial effects of the present utility model:

[0044] When this clamping device is in use, the base 101 can be installed in the processing area for use to facilitate the processing of each process of the leaf spring, improving the applicable range of this clamping device. During the clamping process, place the leaf spring on one side of the base 101, clamp the middle section of the leaf spring through a set of clamping components in the middle, and adjust the distance between the two sets of sliding seats 201 through the adjusting mechanism to adjust the distance between the other two sets of clamping components. Then rotate the clamping components on the sliding seats 201 so that the clamping gap can adapt to the arc of the leaf spring. Finally, clamp the other two sets of clamping components at both ends of the leaf spring. Clamp and process the leaf spring through this device, which can be applicable to leaf springs with different arcs. And compared with the traditional clamping device, it will not apply an inward clamping force to both ends of the leaf spring, effectively preventing the arc of the leaf spring from changing during the processing of the leaf spring and improving the production quality of the leaf spring.

[0045] The basic principles, main features and advantages of the present utility model have been shown and described above. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments. Based on the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection required by the present utility model.
