Description

Technical Field

[0001] The invention relates to the field of automobiles, and in particular to a portable magnetic suction type tool for disassembling and assembling a valve lock clip. Background Art

[0002] The function of the engine valve is to input air into the engine and discharge the exhaust gas after combustion. The valve is opened and closed by the continuous reciprocating motion of the valve stem in the valve guide. In order to realize the relationship of the valve, a valve spring is installed on the valve stem, and the valve lock clamp limits the upper seat of the valve spring. Generally, the valve lock clamp includes two pieces. The outer surface of the valve lock clamp is a conical surface that matches the inner wall surface of the upper seat of the valve spring. The valve stem is provided with a lock clamp groove, and the inside of the valve lock clamp is provided with a boss that matches the lock clamp groove. In the prior art, the installation and removal of the valve lock clamp are relatively difficult. Since the valve lock clamp is very small in size and the force required to compress the valve spring is large, it is easy to pinch the valve spring when squeezing it. Manual installation and removal are laborious and inefficient. During removal, the valve lock clamp may burst out and easily injure people, causing safety hazards. Summary of the invention

[0003] The purpose of the present invention is to provide a tool for simply and conveniently installing and removing a valve lock clip.

[0004] In order to achieve the above-mentioned purpose, the present invention includes a fixed screw, the top end of the fixed screw is hinged with a press handle, the press handle is slidably connected to a slider, and a press head assembly is hinged under the slider, and its structural characteristics are: the press head assembly includes a press head body, the press head body is provided with an inverted cone hole upward along the lower end surface, the upper end surface of the inverted cone hole is provided with a cylindrical hole vertically upward, the diameter of the cylindrical hole is the same as the diameter of the valve stem, the press head body is provided with two blanking grooves that can drop the valve lock clip into the inverted cone hole, the two blanking grooves are arranged obliquely and symmetrically, the press head body is provided with two stepped holes that penetrate the side wall of the inverted cone hole in the horizontal direction, and the two stepped holes are provided outside The hole diameter is larger than the inner hole diameter and the two stepped holes are symmetrically arranged, a slidable push rod is installed in the stepped hole, a top spring is provided in the stepped hole to press the push rod into the inverted cone hole, the inner end surfaces of the two push rods form a accommodating cavity that surrounds the valve lock clip and prevents the valve lock clip from falling, a disassembly component that can receive the push rod into the stepped hole and make the push rod have or lose magnetism is provided on the rear side of the push rod, the disassembly component includes a perforated screw plug, the perforated screw plug is fixed to the outside of the stepped hole by threads, a magnetic knob is installed inside the perforated screw plug, a non-magnetic screw is fixed to the inside of the magnetic knob, and the push rod is provided with a threaded hole for the non-magnetic screw to be screwed in or out.

[0005] After adopting the above structure, the fixing screw is fixed on the cylinder head, and the top end of the fixing screw is hinged with a pressing handle, and the hinge shaft is horizontally arranged. The pressing handle rotates along the hinge shaft, driving the slider on the pressing handle to move up and down, realizing the pressing down and lifting of the pressing head assembly. The slider is slidably connected with the pressing handle, and the slider is hinged with the pressing head assembly. When the pressing handle rotates along the hinge shaft, the slider also rotates accordingly. Due to the influence of gravity, the pressing head assembly rotates relative to the slider at the hinge, so that the pressing head assembly always maintains a vertical state, which is convenient for installing and removing the valve lock clamp. At the same time, the slider slides on the pressing handle, and the pressing head assembly can be adjusted to the corresponding position to install or remove the valve lock clamp of different valve stems; during installation, the pressing head assembly can be pressed down vertically to evenly compress the valve spring to ensure the service life of the valve spring; in the installed state, the push rod extends outward to form a accommodating cavity to hold the valve The locking clip is sent into the inverted cone hole from the blanking chute and then falls into the accommodating cavity. The push rod surrounds the valve locking clip to prevent the valve locking clip from falling. The pressure head assembly is aligned with the valve stem where the valve locking clip needs to be installed, and the pressing handle is pressed down. The lower end of the pressure head body squeezes the valve spring upper seat. The valve spring is squeezed and contracts, and the valve stem enters the accommodating cavity upward and then squeezes the two valve locking clips open to enter the cylindrical hole. When the valve stem moves upward, the upper end of the valve locking clip rests on the upper surface of the inverted cone hole, and the valve locking clip is tightly attached to the valve stem body until the inner groove of the valve locking clip corresponds to the locking clip groove of the valve stem. The valve locking clip is affected by the pressure of the push rod, and the groove of the valve locking clip enters the position added by the valve stem, and the valve locking clip tightly embraces the valve stem. As the pressure head assembly is lifted, the valve stem with the valve locking clip installed withdraws downward from the accommodating cavity, and the valve spring pushes the valve spring upper seat, and the valve spring upper seat wraps the valve locking clip and the valve stem, completing the installation of the valve locking clip.When the valve is disassembled, the disassembly parts are adjusted, the push rod is put into the stepped hole and the push rod is magnetized at the same time. When the valve pressure head presses the valve spring upper seat downward, the valve spring upper seat is pressed downward, the valve stem drives the valve lock clip into the inverted cone hole, and the top end of the valve stem is inserted into the cylindrical hole. The valve lock clip is adsorbed by the magnetic force of the push rod and detaches from the lock clip groove. The valve lock clip is separated from the valve stem, and the removal of the valve lock clip is completed. This structure is used for installation and disassembly, and only different types of pressure head bodies need to be simply replaced to be compatible with various models. The operation is simple and only the handle needs to be pressed, which improves work efficiency. At the same time, it is basically completely closed during the installation and disassembly process, and there is no risk of the lock clip flying out or the top spring being clamped. At the same time, there is no need to clamp the valve lock clip, which avoids damage to the valve lock clip during installation and disassembly, thereby increasing the service life of the valve lock clip. Rotation drives the rotation of the non-magnetic screw. As the non-magnetic screw rotates, the non-magnetic screw extends into the threaded hole of the push rod. Because the relative position of the non-magnetic screw and the pressure head assembly remains unchanged, when the non-magnetic screw is screwed in, it drives the push rod to move into the stepped hole until the push rod is infinitely close to the magnetic knob. At the same time, the top of the push rod is received in the stepped hole. The magnetic knob transmits magnetism to the push rod, making the push rod magnetic as a whole. At this time, the valve spring is squeezed onto the seat through the pressure head assembly, and the valve stem drives the valve lock clip into the inverted cone hole of the pressure head assembly. At this time, the front end of the push rod sucks the valve lock clip out of the lock clip groove of the valve stem through magnetic force, and the valve lock clip falls into the inverted cone hole, completing the removal of the valve lock clip. It is simple and convenient. The magnetic attraction can avoid damage to the valve lock clip during the removal process, ensuring the safety of subsequent use and the service life of the valve lock clip. ;

[0006] The inner end face of the push rod is an inclined face inclined from bottom to top toward the outside. When the valve lock clip falls, the inner end face of the push rod fits with the outer end face of the valve lock clip, and the two valve lock clips fall into the accommodating cavity formed by the two inner end faces of the push rods. Since the lowest end distance of the two inner end faces of the push rods is smaller than the maximum diameter of the annular body formed by the two valve lock clips, the valve lock clip falls into the accommodating cavity and will not continue to fall downward. When installing, the push rod pushes the outer end face of the valve lock clip, and the upper end face of the valve lock clip rests on the upper wall of the inverted cone hole, pushing the valve lock clip into the valve lock clip groove to complete the installation. This structure ensures that the valve lock clip will not fall and will not deflect in the accommodating cavity, thereby ensuring the vertical state of the valve lock clip during installation and ensuring the stability of subsequent installation.

[0007] The thread pitch of the non-magnetic screw is larger than the standard pitch. When the pitch is larger, the number of rotations of the magnetic knob is reduced, the number of rotations required for switching between the installation state and the removal state is saved, the required state is adjusted more accurately, and the efficiency is improved.

[0008] The screw rod is made of plastic material, which is convenient for manufacturing and production, saves production costs, avoids contact between the push rod and magnetic materials during installation, avoids magnetic conduction of the push rod, ensures the thrust for the valve lock clamp during installation, and accurately pushes the valve lock clamp into the lock clamp groove of the gas rod, ensuring installation efficiency.

[0009] The push rod is provided with an annular boss, the annular surface of the annular boss is in contact with the side wall of the large hole of the stepped hole, the outer surface of the boss is provided with a top spring groove, and the inner surface of the perforated screw plug is provided with a corresponding top spring groove. The annular surface of the annular boss abuts against the side wall of the large hole of the stepped hole to play a guiding role. At the same time, the inner surface of the annular boss abuts against the inner wall of the large hole to prevent the top spring from pushing the push rod out. At the same time, the position of the top spring is fixed by the top spring groove of the annular boss, the perforated screw plug and the top spring groove, so that the push of the push rod by the top spring is more stable and the installation of the top spring is convenient.

[0010] The blanking groove is inclined from top to bottom and passes through the side wall of the pressure head body to the upper end surface of the inverted cone hole. The inner surface of the blanking groove is an arc surface that matches the surface of the valve lock clamp, which is convenient for the operator to operate. At the same time, the valve lock clamp will not deflect when it falls into the accommodating cavity after falling, thereby ensuring the stability of subsequent installation.

[0011] The cross-section of the slide rail section of the press-fitting handle is square, and the slider is provided with a through hole that matches the shape of the slide rail. The square cross-section prevents the slider from rotating along the slide rail section at the same time when sliding, so that the pressure head body always remains in a vertical state, ensuring the alignment accuracy during installation and disassembly, avoiding the deflection of the pressure head body, and ensuring stability.

[0012] In summary, the present invention has the advantages of simplicity, convenience, high safety, high applicability, low difficulty in use, and reduced labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] like Figure 1As shown, the present invention comprises a fixed screw 1 and a press handle 2, the press handle 2 is hinged with the top of the fixed screw 1, a slide rail is provided on the press handle 2, a slider 3 is slidably connected to the slide rail, a press head assembly is hinged under the slider 3, and the press head assembly comprises a press head body 4. The lower end of the fixed screw 1 is provided with a thread matching with the rocker arm mounting hole on the cylinder head, and the fixed screw 1 can be fixedly connected to the cylinder head through a threaded connector. The top of the fixed screw 1 is hinged with the press handle 2, the hinge axis is horizontally arranged, the press handle 2 rotates along the hinge axis, driving the slider 3 and the press head assembly on the press handle 2 to move up and down, when the press handle 2 rotates along the hinge axis, the slider 3 also rotates accordingly, and the press head assembly rotates relative to the slider 3 at the hinge due to the influence of gravity, so that the press head assembly always maintains a vertical state, which is convenient when installing and removing the valve lock clamp 82, the press head assembly can be pressed vertically downward to evenly compress the valve spring 83, and ensure the service life of the valve spring 83. The cross-section of the slide rail section of the press-fitting handle 2 is square, and the slider 3 is provided with a through hole that matches the shape of the slide rail. The square cross-section prevents the slider 3 from rotating along the slide rail section at the same time when sliding, so that the main body of the pressure head always remains in a vertical state, ensuring the alignment accuracy during installation and disassembly, avoiding the deflection of the main body of the pressure head, and ensuring stability.

[0019] like Figure 1-5As shown, the ram body 4 is a cylindrical body, and the lower end surface of the ram body 4 is provided with an inverted cone hole 41 upwardly, and the center point of the upper end surface of the inverted cone hole 41 is provided with a cylindrical hole 42, and the diameter of the cylindrical hole 42 is the same as the outer diameter of the valve stem 81. Two blanking grooves 43 are provided on the side wall of the ram body 4, which penetrate the inside of the ram body 4. The blanking grooves 43 are inclined inward from top to bottom, and the blanking grooves 43 penetrate the side wall of the ram body 4 to the upper end surface of the inverted cone hole 41. The cross section of the blanking grooves 43 is an arc shape, which can allow the valve lock clamp 82 to slide in the blanking grooves 43 and fall into the inverted cone hole 41 after sliding out. The outer surface of the two valve lock clamps 82 when put together is inverted cone shape. Two stepped holes are provided on the ram body 4, which penetrate the side wall of the inverted cone hole 41 in the horizontal direction. The outside of the stepped hole is provided with a thread, the inner hole diameter is smaller than the outer hole diameter, and the two stepped holes are symmetrically arranged. A push rod 5 is installed in the stepped hole, which can slide along the stepped hole and extend into the inverted tapered hole 41. A top spring 6 is provided at the rear of the push rod 5. A magnetically conductive disassembly component is installed in the stepped hole, which can receive the push rod 5 into the stepped hole. A screw plug 7 with a hole is threadedly connected to the outside of the stepped hole, and a disassembly component is slidably connected in the hole of the screw plug 7 with a hole. The prestress of the top spring is adjusted by installing the screw plug 7 with a hole. The push rod 5 is provided with an annular boss, the annular surface of the annular boss is fitted with the large hole side wall of the stepped hole 41, the outer surface of the boss is provided with a top spring groove, and the inner surface of the screw plug 7 with a hole is provided with a corresponding top spring groove. The annular surface of the annular boss abuts against the large hole side wall of the stepped hole 41 to play a guiding role. At the same time, the inner surface of the annular boss abuts against the inner wall of the large hole to prevent the top spring 6 from pushing the push rod 5 out. At the same time, the top spring groove of the annular boss and the screw plug 7 with a hole and the top spring groove fix the position of the top spring, so that the push of the push rod 5 by the top spring 6 is more stable, and the installation of the top spring 6 is convenient. The disassembly component includes a magnetic knob 8, which includes a handle and a sliding section. By rotating or pushing the magnetic knob 8, the magnetic knob 8 can be rotated or slid in the screw plug 7 with a hole. The length of the longest section of the handle is greater than the aperture of the screw plug 7 with a hole. The handle limits the relative position of the magnetic knob 8 and the screw plug 7 with a hole to prevent the magnetic knob 8 from entering the screw plug 7 with a hole, which facilitates the operation. The front end faces of the two push rods 5 are inclined surfaces and the distance from top to bottom gradually decreases, and the two front end faces are symmetrical to each other to form a receiving cavity. When the valve lock clamp 82 falls, since the distance between the lowest ends of the front end faces of the two push rods 5 is less than the maximum diameter of the annular body formed by the two valve lock clamps, the valve lock clamp 82 falls into the receiving cavity and will not continue to fall down. The inner end of the magnetic knob 8 is fixedly connected with a non-magnetic screw 44, and the push rod 5 is provided with a threaded hole corresponding to the thread of the non-magnetic screw 44. In this embodiment, the non-magnetic screw 44 is made of plastic, and other non-magnetic materials can also be used. A ring platform is provided on the push rod 5, and the inner surface of the ring platform is against the inner wall of the stepped hole to prevent the top spring 6 from pushing the push rod 5 out. The outer surface of the ring platform is provided with a top spring groove for installing the top spring 6, and the inner surface of the perforated screw plug 7 is provided with a top spring groove corresponding to the push rod 5, fixing the position of the top spring 6, so that the push of the push rod 5 is more stable.

[0020] like Figure 1-5 As shown, when the valve lock clamp 82 needs to be installed. When the magnetic knob 8 is rotated to the installation state, the non-magnetic screw 44 is not screwed into the push rod 5. The push rod 5 is pushed forward by the elastic force of the top spring 6. At this time, the push rod 5 is a certain distance away from the magnetic screw 44 and is not affected by the magnetic screw 44. The push rod 5 is not magnetic, and the inner end surface of the push rod 5 extends into the inverted cone hole 41 to form an accommodating cavity. The valve lock clamp 82 falls into the inverted cone hole 41 of the pressure head body 4 through the blanking groove 43. The valve lock clamp 82 that falls into the inverted cone hole 41 falls between the two push rods 5, is surrounded by the inner end surface of the push rod 5, and enters the accommodating cavity formed by the two push rods 5 to prevent the valve lock clamp 82 from falling. At the same time, it is ensured that the valve lock clamp 82 will not deflect in the accommodating cavity, ensuring the vertical state of the valve lock clamp 82 during installation and ensuring the stability of subsequent installation. At this time, the pressing rod is used to press the pressing head body 4 downward, and the lower surface of the pressing head body 4 squeezes the valve spring upper seat 84 surrounded by the valve stem 81, compressing the valve spring 83. After the valve spring 83 is compressed, the pressing head body 4 is pressed downward, and the exposed valve stem 81 enters the inverted cone hole 41 of the pressing head body 4 as the valve spring 83 is compressed, until it extends into the cylindrical hole 42 of the inverted cone hole 41. The upper side of the valve stem 81 is provided with an annular groove for the valve lock clip 82, and the valve lock clip 82 has a corresponding boss therein. At this time, the valve stem 81 squeezes the two valve lock clips 82 and moves upward, and the upper end of the valve lock clip 82 abuts against the upper end surface of the inverted cone hole 41. When the valve stem 81 extends into the annular groove corresponding to the valve lock clip 82, the valve lock clip 82 is pressed into the lock clip groove by the push rod 5 and the hole wall of the inverted cone hole 41. At this time, the pressure rod is lifted, driving the valve lock clip 82 to lift up, and the pressure head body 4 moves upward. As the pressure head body 4 moves, the valve spring 83 extends, and the valve lock clip 82 installed in the lock clip groove moves downward relative to the pressure head body 4. The push rod 5 is pressed outward by the force of the valve lock clip 82 after it is stuck in the valve stem 81. The push rod 5 slides outward, the top spring 6 is compressed, and the valve lock clip 82 continues to be squeezed. Under the tight embrace of the push rod 5, the valve lock clip 82 is always stuck in the lock clip groove of the valve stem 81 and will not fall out. When the pressure head body 4 moves to the upper end of the valve lock clip 82, the valve spring upper seat 84 at the upper end of the extended valve spring 83 clamps the valve lock clip 82. As the tooling is withdrawn, the valve lock clip 82 is inserted into the valve spring upper seat 84, and the installation of the valve lock clip 82 is completed. The entire installation process is simple and convenient, and the operation is simple. Only one person is required to complete the installation of the valve lock clip 82 at the same time. At the same time, the press-fitting handle 2 is used, which saves the required force for compressing the valve spring 83, improves the operating efficiency, and saves labor costs.

[0021] like Figure 1-5As shown, when the valve lock clamp 82 needs to be removed, the magnetic knob 8 is rotated, and the plastic screw at the front end of the magnetic knob 8 is rotated and screwed into the push rod 5. The handle limits the position of the magnetic knob 8. As the plastic screw rotates and penetrates into the push rod 5, the push rod 5 is retracted into the groove. When the push rod 5 and the magnetic knob 8 are in contact or close to each other, the magnetic knob 8 transmits magnetic force to make the push rod 5 magnetic. At this time, the press handle 2 is pressed down, and the pressure head body 4 is pressed down. The pressure head body squeezes the upper end surface of the valve spring upper seat 84 after being pressed down, and the valve spring 83 is compressed. At this time, the valve stem 81 enters the accommodating cavity and extends into the cylindrical hole 42 of the accommodating cavity. The valve lock clamp 82 clamped on the valve stem 81 also enters the inverted cone hole 41 along with the valve pressure head as the valve stem 81 is pressed down. When the height of the valve lock clip 82 is consistent with the height of the push rod 5, the magnetism of the push rod 5 adsorbs the valve lock clip 82 and removes the valve lock clip 82 from the lock clip groove of the valve stem 81. Since the push rod 5 is received in the stepped hole, the side wall of the inverted cone hole 41 is a certain distance away from the valve lock clip 82 that has not been removed. When the valve lock clip 82 is removed and adsorbed by the push rod 5, it can be completely removed from the lock clip groove, avoiding the valve lock clip 82 being unable to completely remove the buckle, resulting in the difficulty of the valve stem 81 to withdraw from the inverted cone hole 41 when the pressure head body 4 is lifted, thereby avoiding damage to the valve lock clip 82 during the withdrawal of the valve stem 81. The valve lock clip 82 remains in the inverted cone hole 41. At this time, the press handle 2 moves up, the pressure head body 4 moves up, the valve stem 81 exits the cylindrical hole 42, and the upper cover of the valve spring 83 stretches and wraps the valve stem 81 as the pressure head body 4 moves up. When the valve stem 81 exits the pressure head body 4, the valve lock clip 82 remains in the accommodating cavity, realizing the disassembly of the valve lock clip 82. The disassembly and assembly of the valve lock clip 82 is completed by magnetic attraction, and the valve lock clip remains in the inverted cone hole 41, reducing the risk of the valve lock clip 82 flying out, ensuring the safety of the valve lock clip 82 during installation and removal, and avoiding damage to the valve lock clip 82 when taking it out, ensuring the safety of subsequent use and the service life of the valve lock clip 82. At the same time, the pressure head body 4 is pressed, and the extrusion force is small, which saves human resources and improves efficiency. After adopting this tooling, by replacing different types of pressure heads, it can achieve universality of various models, avoiding the pressure injury of the top spring 6, and the installation and disassembly conversion is convenient. Only by turning the knob, the function of installation and disassembly can be changed.
