The portion for clamping the signal disk on the rear side of the movable pressing head 5 can be disassembled from the movable pressing head 5, so as to facilitate the adaptive replacement when different signal disks and camshafts need to be replaced, and is convenient for use.

[0025] like Figure 2As shown, the movable support plate 3 includes a limit slide rail 31 and a stroke electric cylinder 33. The limit slide rail 31 is fixedly installed on the top of the base 1, and the stroke electric cylinder 33 is movably installed in the installation groove 2. The top of the limit slide rail 31 is movably clamped with a sliding plate body 32, and the bottom of the sliding plate body 32 is connected to the stroke electric cylinder 33. An empty slot 34 is opened in front of the top of the sliding plate body 32, and a guide column 35 is fixedly installed inside the empty slot 34. The outside of the guide column 35 is movably sleeved with a spring 36. The movable pressing head 5 is movably installed inside the empty slot 34, and the clamping member 4 is arranged behind the movable pressing head 5.

[0026] The sliding plate body 32 is driven to move laterally along the limiting slide rail 31 by controlling the stroke electric cylinder 33. The sliding plate body 32 is driven to move a specified stroke along the limiting slide rail 31 according to the positions of the clamping piece 4, the movable pressing head 5 and the pressing assembly 6 by the stroke electric cylinder 33. The pressing assembly 6 switches between the clamping piece 4 and the movable pressing head 5 on the sliding plate body 32 for pressing. Thus, continuous operation can be performed without waiting for a camshaft to be pressed and then replaced, thereby improving the pressing efficiency.

Fixing bolts 57 are installed on the internal threads of the fixing holes 56.

[0029] The camshaft is clamped on the clamping block 42 and pressed against the plate 43, and the movable pressing head 5 corresponding to the clamping piece 4 is matched, and the signal disk is clamped in the placement frame 54. The sliding block 51 is pushed backward along the movable support plate 3 by the pressing assembly 6, so that the signal disk in the placement frame 54 is pressed close to the camshaft, thereby facilitating the press-fitting of multiple camshafts and signal disks and improving the press-fitting efficiency.

[0030] like Figure 5 As shown, the press-fitting assembly 6 includes a support seat 61, a press-fitting cylinder 62 and a limit seat 63 are fixedly installed on the top of the support seat 61, the press-fitting cylinder 62 is slidably connected to the inside of the limit seat 63, and a sleeve 64 is fixedly installed on the rear side of the press-fitting cylinder 62.

[0031] The sleeve 64 is pushed backward by the press-fitting cylinder 62 to push the signal disk in the movable press-fitting head 5 close to the cam shaft on the clamping member 4 to complete the press-fitting.

[0032] like Figure 3 As shown, the clamping member 4 and the movable pressing head 5 are equidistantly arranged on the top of the sliding plate body 32 .

[0033] The clamping member 4 and the movable pressing head 5 are equidistantly arranged on the sliding plate 32, and the travel electric cylinder 33 drives the sliding plate 32 to move the travel between the clamping member 4 to switch the camshaft and the signal disk, thereby improving the pressing efficiency.

[0035] The sliding block 51 can slide backward along the matching guide column 35 in the empty slot 34 to complete the press-fitting, and the spring 36 is squeezed and releases the elastic force to push the sliding block 51 to return to its original position.

[0036] like Figure 1 As shown, the placement frame 54 and the clamping block 42 are coaxially arranged.

[0037] The placement frame 54 and the clamping block 42 are coaxially arranged to ensure accurate alignment of the camshaft and the signal disk.

[0038] The following is a detailed description of the working principle of the press-fitting equipment for the engine camshaft signal plate.

[0039] like Figures 1 to 5As shown, by installing the camshaft in the clamping block 42 on the base frame 41, so that its rear side is located in the abutment plate 43 and pressed tightly, and the corresponding card of the signal disk is placed in the placement frame 54 in front of the corresponding camshaft, the sliding plate body 32 is driven to move horizontally along the limiting slide rail 31 by controlling the stroke electric cylinder 33, and after the position of the movable pressing head 5 on the top of the sliding plate body 32 is moved to the corresponding position of the pressing assembly 6, the sleeve head 64 is pushed backward by the pressing cylinder 62, so that the sleeve head 64 contacts the front side of the sliding block 51 and pushes the sliding block 51 to move backward along the empty groove 34, and the placement frame 54 is driven backward by the sliding block 51, so that the signal disk inside it is pressed onto the camshaft behind it, and the sliding block 51 is reset by the pressing assembly 6 to be affected The spring 36 pushes the reset, and the travel electric cylinder 33 drives the sliding plate body 32 to move to the position of the next active pressing head 5 for the next pressing. At the same time, the camshaft after pressing can be removed and replaced from the card release part 4, so as to facilitate continuous pressing and improve efficiency. When using different types of discs to correspond to camshafts, the fixing bolts 57 are removed to make the fixing bolts 57 detach from the inside of the sliding block 51 and the card block 55, and the positioning disc 53 is pulled outward from the card slot 52 to drive the card block 55 to detach from the inside of the card slot 52, and the positioning disc 53 with a matching placement frame 54 is replaced, and the card block 55 behind it is inserted into the card slot 52, and the fixing bolts 57 are used to pass through the fixing holes 56 to fix it for replacement and use.
