Description

Technical Field

[0001] The utility model belongs to the technical field of camshaft processing tooling, and particularly relates to a camshaft clamping tooling. Background Art

[0002] A camshaft is a component in a piston engine. Its function is to control the opening and closing of the valves. Usually, its rotational speed is still very high, and it needs to withstand a large torque. Therefore, in the design, the requirements for the camshaft in terms of strength and support are very high. The design of the camshaft occupies a very important position in the design process of the engine.

[0003] Currently, during the production and processing of camshafts, it is necessary to install components such as speed rings at the ends of some camshafts. When installing, usually two people are required to operate. The camshaft is placed on a transport trolley. One operator holds the camshaft firmly, and the other operator uses a torque wrench to perform the installation and tightening operation. However, if the camshaft cannot be kept stable at all times during the process of being held by the person, it will damage the camshaft during the installation of components, not only with low efficiency but also easily causing damage to the camshaft.

[0037] As Figure 1-2 shown, a camshaft clamping tooling provided by the present utility model includes: a frame, a supporting platform and a jaw assembly arranged on the frame.

[0038] The supporting platform is arranged at the bottom of one side of the frame and is used to abut against the bottom end face of the workpiece; the jaw assembly is arranged on the frame above the supporting platform. Among them, the jaw assembly includes: a first jaw and a second jaw, the first jaw and the second jaw are arranged at intervals, the first jaw is clamped on the frame and is detachably connected to the frame, the second jaw is arranged at intervals with the first jaw through a push-pull assembly, and the push-pull assembly is used to drive the second jaw to reciprocate close to or away from the first jaw to cooperate with the first jaw to clamp the top end of the workpiece.

[0039] The frame stabilizes the supporting platform and the jaw assembly. The frame mainly serves to stabilize the supporting platform and the jaw assembly. The supporting platform is used to abut against the bottom of the workpiece, and the jaw assembly is used to clamp the top of the workpiece. Moreover, the first jaw in the jaw assembly is clamped to the frame to form a detachable connection, which is convenient for replacing the first jaw. The same is true for the second jaw, which is connected to the push-pull assembly, not only realizing a detachable connection, being convenient for replacement, and being able to clamp workpieces of different specifications, but also the push-pull assembly can drive the second jaw to separate from or approach the first jaw to clamp or separate the workpiece, which is overall convenient and fast.

[0040] Specifically, the frame is a three-dimensional frame structure. A concave clamping position matching the first jaw is formed at a corner of the top of the frame. The first jaw is detachably clamped in the concave clamping position. A supporting plate for supporting the bottom of the first jaw is arranged at the bottom of the clamping position. The first jaw is inserted into the clamping position from the top of the clamping position. One side edge of the supporting plate located in the clamping position is fixed to the frame near the clamping position, and the other side partially extends into the clamping position, playing a role in supporting the first jaw and at the same time facilitating the taking of the first jaw from the vacant position of the supporting plate.

[0041] To ensure the stability of the first jaw in the clamping position, a baffle is provided outside the clamping position, which fits the outer side surface of the first jaw. A pin rod is penetrated through the baffle, and a pin hole matching the pin rod is provided on the first jaw. After the first jaw is placed in the clamping position, the pin rod is inserted into the pin hole to make the first jaw stably placed and not shake during the clamping process.

[0042] It also includes at least one auxiliary positioning block provided on the frame. In this embodiment, one auxiliary positioning block is shown, and multiple auxiliary positioning blocks can be arranged at intervals along the length direction of the workpiece. The auxiliary positioning block is located on the frame between the supporting platform and the jaw assembly. A circumferential positioning notch for fitting the workpiece is formed on the auxiliary positioning block. When the workpiece is placed, the notch on the auxiliary positioning block fits on the outer peripheral surface of the workpiece.

[0043] In this embodiment, the pushing and pulling assembly includes: an extension plate and a pushing and pulling clamp.

[0044] One end of the extension plate is connected to the frame, and the other end extends away from the first jaw. The pushing and pulling clamp is fixed on the extension plate, so that the reciprocating movement direction of the pushing and pulling clamp is opposite to that of the first jaw, so that the second jaw can be pushed and pulled close to the first jaw to clamp the workpiece, or away from the first workpiece to make the workpiece loose. The second jaw and the acting end of the pushing and pulling clamp are detachably connected, which is convenient to replace different specifications like the first jaw.

[0045] To avoid damaging the workpiece and play a buffering and protecting role, a buffer cushion layer is provided. The buffer cushion layer covers the supporting platform and the jaw assembly, and the buffer cushion layer is not shown in the figure.

[0046] In addition, a placement platform for placing the workpiece is formed on the top of the frame.

[0047] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
