Summary of the invention
Goal of the invention of the present invention is to provide a kind of reset torsion spring to install compressing tablet and processing method, can realize reset torsion spring and be connected with the reliable of guide pad.
Based on same inventive concept, the present invention has two independently technological schemes:
1, a compressing tablet installed by reset torsion spring, and it is characterized in that: have mainboard and lamina affixa, mainboard is set in parallel in the top of lamina affixa, and on mainboard and lamina affixa, correspondence is provided with reset torsion spring mounting hole; The left side of mainboard, right side, front side can bend downwards, corresponding formation left catch, right catch, front catch; Rear side and the lamina affixa of mainboard link into an integrated entity.
Reset torsion spring installs compressing tablet entirety in trapezoidal, the minor face that the rear side of mainboard is corresponding trapezoidal.
Reset torsion spring mounting hole is waist shaped hole.
Left catch, right catch, front catch are perpendicular to mainboard, and the bottom of left catch, right catch, front catch all connects with lamina affixa end face, and reset torsion spring arm mounting hole is left in front catch both sides.
2, utilize above-mentioned reset torsion spring that a manufacture method for compressing tablet is installed, it is characterized in that:
Step 1: utilize cutting mode to obtain the sheet metal part of reservation shape, the large end portion of sheet metal part is corresponding mainboard, and the small end part of sheet metal part is corresponding lamina affixa; Large end portion and the equal correspondence of small end part of sheet metal part are processed with reset torsion spring mounting hole;
Step 2: the left and right sides of mainboard is bent downwards form left catch, right catch;
Step 3: the small end of sheet metal part divided and bend, forms the lamina affixa being parallel to mainboard;
Step 4: space reset torsion spring mounting arm being snapped in mainboard and lamina affixa, then be bent to form front catch downwards by front side of mainboard.
The beneficial effect that the present invention has:
The present invention has mainboard and lamina affixa, the left side of mainboard, right side, front side can bend downwards, the left catch of corresponding formation, right catch, front catch, left catch, right catch, front catch can play good Horizontal limiting effect to reset torsion spring mounting arm, structure of the present invention is simple, cost is low, manufacturing process is simple, easy for installation, reset torsion spring can be located well and be arranged on guide pad, registration, connect more reliable, the distortion in the course of the work of reset torsion spring can be reduced simultaneously, thus improve the reliability of full variable valve lift control system.
The present invention's torsion spring that resets installs compressing tablet entirety in trapezoidal, the minor face that the rear side of mainboard is corresponding trapezoidal, more convenient spacing to reset torsion spring mounting arm.The present invention's torsion spring mounting hole that resets is waist shaped hole, take into full account that reset torsion spring has individual displacement amount in actual motion process, avoid construction bolt and reset torsion spring mounting arm and compressing tablet mounting hole periphery wear, ensure the reliability that reset torsion spring is connected with guide pad further.The left catch of the present invention, right catch, front catch are perpendicular to mainboard, and the bottom of left catch, right catch, front catch all connects with lamina affixa end face, can strengthen the supporting effect in vertical direction of reset torsion spring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation under another angle of the present invention;
The sheet metal part plan view that Fig. 3 uses when being and manufacturing of the present invention;
Fig. 4 is using state figure of the present invention.
Embodiment
As shown in Figure 1 and Figure 2, have mainboard 1I and lamina affixa 1II, mainboard 1I is set in parallel in the top of lamina affixa 1II, and on mainboard 1I and lamina affixa 1II, correspondence is provided with reset torsion spring mounting hole 3, and during enforcement, reset torsion spring mounting hole 3 is waist shaped hole; The left side of mainboard 1I, right side, front side can bend downwards, corresponding formation left and right catch 2I and front catch 2II; Rear side and the lamina affixa 1II of mainboard 1I link into an integrated entity.Left and right catch 2I, front catch 2II are perpendicular to mainboard 1I, and the bottom of left and right catch 2I, front catch 2II all connects with lamina affixa 1II end face, and reset torsion spring arm mounting hole 4 is left in front catch 2II both sides.Reset torsion spring installs compressing tablet entirety in trapezoidal, the minor face that the rear side of mainboard is corresponding trapezoidal.
Manufacture the present invention reset torsion spring install compressing tablet time:
Step 1: utilize cutting mode to obtain the sheet metal part of reservation shape, as shown in Figure 3, the large end portion of sheet metal part is corresponding mainboard, and the small end part of sheet metal part is corresponding lamina affixa; Large end portion and the equal correspondence of small end part of sheet metal part are processed with reset torsion spring mounting hole;
