Description

Technical Field

[0001] The invention belongs to the technical field of flywheel housing installation, and relates to a gluing auxiliary device for a flywheel housing installation surface. Background Art

[0002] The flywheel housing is typically installed between the engine and transmission, connected to the crankcase, and housing the flywheel assembly, starter, oil pan, and other components. The flywheel housing typically consists of an outer shell, a support plate, and bolts. The outer shell has screw holes on both sides, and the support plate also has bolt holes. The bolts pass through the bolt holes in the support plate and screw into the screw holes in the outer shell, securing the support plate to the outer shell.

[0003] A common flywheel housing currently consists of a main body, connection holes (for bolts to connect to the engine or other components), a mounting collar on the back of the main body, and a spindle hole in the center. When installing the flywheel housing, first clean the mounting surface with a non-woven cloth and inspect the housing to ensure it is free of cracks. Then, use a glue gun to evenly apply glue, such as conventional Loctite, to the mounting surface, maintaining a width of 2-3mm. If the housing is not assembled within 5 minutes or tightened within 15 minutes after application, remove the glue and reapply.

[0004] Since the shape of the mounting cam is irregular and there are connection holes, the glue gun needs to move in an arc shape and apply the glue to the inside of the connection hole. This not only makes the operation more difficult, but also prolongs the gluing time, which easily leads to the situation of scraping off the glue after the timeout, resulting in poor gluing effect. Summary of the Invention

[0005] The purpose of the present invention is to provide a gluing auxiliary device for the mounting surface of a flywheel housing, aiming to solve the problem of poor gluing effect.

[0006] In order to solve the above technical problems, the present invention provides a flywheel housing mounting surface gluing auxiliary device, comprising:

[0007] An outer contour ring, wherein a plurality of limiting columns are vertically arranged on the outer side of the outer contour ring;

[0008] An inner contour ring, the bottom of which contacts the top of a flywheel housing and is fixedly connected to the flywheel housing, the top of the flywheel housing is provided with a mounting bead, the top of the mounting bead is a mounting surface, a plurality of positioning holes are formed through the mounting bead, and a main shaft hole is formed in the middle of the flywheel housing;

[0009] An annular guide ring is formed between the outside of the inner contour ring and the inside of the outer contour ring, and the guide ring is located above the mounting surface.

[0010] The present invention is further configured such that a support ring is provided at the bottom of the inner contour ring, the outer side of the support ring is fitted to the inner side of the mounting convex ring, and the bottom thereof is in contact with the top of the flywheel housing.

[0011] The present invention is further configured such that the inner side of the top of the outer contour ring and the outer side of the top of the inner contour ring are both rounded or chamfered.

[0012] The present invention is further configured such that the limiting column includes a first limiting portion and a second limiting portion, the top of the first limiting portion is at the same height as the top of the second limiting portion, and the bottom of the first limiting portion is lower than the bottom of the second limiting portion.

[0013] The present invention is further configured to include a vertical connecting tube, the outer wall of which is in contact with the inner wall of the main shaft hole, and a plurality of connecting parts are provided on the inner wall of the inner contour ring, and the free end of each connecting part is connected to the connecting tube.

[0014] The present invention is further configured such that a trumpet-shaped guide portion is provided at the bottom of the connecting tube, and an opening at the top of the guide portion is larger than an opening at the bottom.

[0015] The present invention is further configured to include a support platform and a limiter with an L-shaped cross section provided on the top of the support platform, wherein both sides of the flywheel housing are fitted to the inner wall of the limiter;

[0016] A connecting plate is provided on the inner wall of the connecting cylinder, and an anti-rotation column with an elliptical cross-section is vertically provided on the bottom of the connecting plate. An anti-rotation hole matching the anti-rotation column is provided on the top of the support platform, and the outer wall of the anti-rotation column is fitted to the inner wall of the anti-rotation hole. The anti-rotation column passes through the guide part, and the bottom of the anti-rotation column is dome-shaped.

[0017] The present invention is further configured such that the anti-rotation column is hollow, a plurality of observation holes are provided on the connecting plate, an operating panel is provided on the top of the connecting tube, and four finger holes and two thumb holes are provided on the operating panel for operation with the left or right hand.

[0018] The present invention is further configured such that a cover-shaped terminating shell is provided on the inner side of the inner contour ring, a terminating member is horizontally movably provided in the terminating shell, the longitudinal section of the terminating member is rectangular, and the outer wall of the terminating member is movably fitted to the inner wall of the terminating shell, a clearance hole for the terminating member to movably pass through is provided on the outer side of the inner contour ring, an elastic member that is continuously in a compressed state is provided between the end of the terminating member away from the outer contour ring and the inner wall of the terminating shell, and the side portion of the end of the terminating member away from the elastic member is chamfered or rounded;

[0019] A long strip operating hole is vertically opened through the terminating shell, and operating parts are provided on the top and bottom of the terminating member, and the operating parts moveably pass through the operating hole.

[0020] The present invention is further configured to include an integral ring, the outer side of the integral ring being fitted to the inner side of the outer contour ring, and the inner side being fitted to the outer side of the inner contour ring, and an indicator ring being provided on the top of the integral ring. When the bottom of the integral ring is in contact with the mounting boss, the indicator ring is higher than the outer contour ring and the inner contour ring, and the vertical projections of the outer contour ring and the inner contour ring are both located within the projection of the indicator ring in the vertical direction.

[0021] Compared with the prior art, the present invention provides a gluing auxiliary device for the flywheel housing mounting surface. Before gluing, the outer contour ring and the inner contour ring are first installed on the flywheel housing, and then the gun head of the glue gun is clamped in the guide ring and moved along the guide ring. During the movement, the two sides of the guide ring move and fit on the outer contour ring and the inner contour ring respectively, so that the angle and trajectory stability of the gun head can be stably maintained; when the gun head has made a circle, the glue gun head is taken out of the guide ring, and the outer contour ring and the inner contour ring are removed from the flywheel housing, and then the flywheel housing and the body can be assembled.

[0022] Because the guide ring guides and directs the gun tip, the desired glue trajectory and shape are achieved, ensuring effective glue application. Furthermore, since glue breakage is avoided, the flywheel housing can be quickly installed after removing the outer and inner contour rings, ensuring efficient assembly. The gun tip is frustum-shaped—larger at the top and smaller at the bottom—so there's a gap between the tip and both the outer and inner contour rings. This effectively prevents glue from being applied to the outer and inner contour rings after extrusion, ensuring the cleanliness of the auxiliary device for subsequent normal use.

DETAILED DESCRIPTION

[0038] The following is a further detailed description of the flywheel housing mounting surface gluing assist device proposed by the present invention, with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are highly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention. Identical or similar reference numerals in the drawings represent identical or similar components.

[0039] A flywheel housing mounting surface glue auxiliary device, such as Figures 1 to 14 As shown, including:

[0040] An outer contour ring 1, wherein a plurality of limiting posts 2 are vertically arranged on the outer side of the outer contour ring 1;

[0041] An inner contour ring 3, the bottom of which contacts the top of a flywheel housing 4 and is fixedly connected to the flywheel housing 4. A mounting bead 5 is provided on the top of the flywheel housing 4. The top of the mounting bead 5 is a mounting surface 6. A plurality of positioning holes 7 are provided through the mounting bead 5. A main shaft hole is provided in the middle of the flywheel housing 4. The flywheel housing 4 and other product structures are not within the scope of protection claimed in this application and are merely recorded to facilitate understanding.

[0042] An annular guide ring is formed between the outside of the inner contour ring 3 and the inside of the outer contour ring 1 , and the guide ring is located above the mounting surface 6 .

[0043] A support ring 8 is provided at the bottom of the inner contour ring 3. The outer side of the support ring 8 is in contact with the inner side of the mounting bead 5, and the bottom thereof abuts against the top of the flywheel housing 4. The inner side of the top of the outer contour ring 1 and the outer side of the top of the inner contour ring 3 are both rounded or chamfered.

[0044] The limiting column 2 includes a first limiting portion 2a and a second limiting portion 2b. The top of the first limiting portion 2a is at the same height as the top of the second limiting portion 2b, and the bottom of the first limiting portion 2a is lower than the bottom of the second limiting portion 2b.

[0045] It also includes a vertical connecting tube 9, the outer wall of which fits against the inner wall of the spindle hole. The inner wall of the inner contour ring 3 is provided with a plurality of connecting portions 10, the free end of each connecting portion 10 being connected to the connecting tube 9. A trumpet-shaped guide portion 11 is provided at the bottom of the connecting tube 9, the top opening of the guide portion 11 being larger than the bottom opening. It also includes a support platform 12 and a limiter 13 with an L-shaped cross section disposed on the top of the support platform 12. Both sides of the flywheel housing 4 fit against the inner wall of the limiter 13.

[0046] The inner wall of the connecting tube 9 is provided with a connecting plate 14, and an anti-rotation column 15 with an elliptical cross-section is vertically provided at the bottom of the connecting plate 14. The top of the support platform 12 is provided with an anti-rotation hole 16 that cooperates with the anti-rotation column 15. The outer wall of the anti-rotation column 15 is fitted to the inner wall of the anti-rotation hole 16. The anti-rotation column 15 passes through the guide part 11, and the bottom of the anti-rotation column 15 is dome-shaped.

[0047] The anti-rotation column 15 is hollow, and a plurality of observation holes are provided on the connecting plate 14. An operating panel 17 is provided on the top of the connecting tube 9. The operating panel 17 has four finger holes 18 and two thumb holes 19 for operation with the left or right hand.

[0048] A cover-shaped terminating shell 20 is provided on the inner side of the inner contour ring 3, and a terminating member 21 is horizontally movably provided in the terminating shell 20. The longitudinal section of the terminating member 21 is rectangular, and the outer wall of the terminating member 21 is movably fitted to the inner wall of the terminating shell 20. A clearance hole 22 for the terminating member 21 to movably pass through is opened on the outer side of the inner contour ring 3. An elastic member 23 that is continuously in a compressed state is provided between the end of the terminating member 21 away from the outer contour ring 1 and the inner wall of the terminating shell 20. The side of the end of the terminating member 21 away from the elastic member 23 is chamfered or rounded.

[0049] An elongated operating hole 24 is vertically opened through the terminating shell 20 . Operating portions 25 are provided on the top and bottom of the terminating member 21 . The operating portions 25 are movable through the operating hole 24 .

[0050] It also includes an integral ring 26, the outer side of the integral ring 26 is in contact with the inner side of the outer contour ring 1, and the inner side is in contact with the outer side of the inner contour ring 3. An indicator ring 27 is provided on the top of the integral ring 26. When the bottom of the integral ring 26 abuts against the mounting boss 5, the indicator ring 27 is higher than the outer contour ring 1 and the inner contour ring 3, and the vertical projections of the outer contour ring 1 and the inner contour ring 3 are both located within the projection of the indicator ring 27 in the vertical direction.

[0051] The gluing auxiliary device for the flywheel housing mounting surface provided by the present invention, before gluing, first installs the outer contour ring 1 and the inner contour ring 3 on the flywheel housing 4, then the gun head of the glue gun is clamped in the guide ring and moves along the guide ring. During the movement, the two sides of the guide ring move and fit on the outer contour ring 1 and the inner contour ring 3 respectively, so that the angle and trajectory stability of the gun head can be stably maintained; when the gun head has made a circle, the glue gun head is taken out of the guide ring, and the outer contour ring 1 and the inner contour ring 3 are removed from the flywheel housing 4, and then the flywheel housing 4 can be assembled with the body.

[0052] Because the guide ring guides and directs the gun tip, the desired glue trajectory and shape are achieved, ensuring effective glue application. Furthermore, since glue breakage is avoided, the flywheel housing 4 can be quickly installed after removing the outer and inner contour rings 1 and 3, ensuring efficient assembly. The gun tip is also frustum-shaped—larger at the top and smaller at the bottom—so there's a gap between the tip and the outer and inner contour rings 1 and 3. This effectively prevents glue from acting on the outer and inner contour rings 1 and 3 after extrusion, ensuring the cleanliness of the auxiliary device for subsequent normal use.

[0053] During actual use, the outer contour ring 1 and the inner contour ring 3 must first be fitted onto the integral ring 26, and both the outer contour ring 1 and the inner contour ring 3 must contact the indicator ring 27. At this point, the outer contour ring 1, the integral ring 26, and the inner contour ring 3 fit together and maintain their shape. Together, the three ensure strength and prevent deformation during operation.

[0054] The flywheel housing 4 is then placed on the support platform 12 and moved so that two sides of the flywheel housing 4 are in contact with the inner wall of the retaining body 13. At this point, the position of the flywheel housing 4 and the support platform 12 remains stable. The present application primarily applies to flywheel housings 4 having two adjacent sides that can be secured to the retaining body 13, but this is not applicable to all flywheel housings. Alternatively, the present application may also apply to flywheel housings 4 that are not secured by retaining bodies 13 but instead are secured by a quick-action clamp or the like.

[0055] After the flywheel housing 4 is stabilized, the overall structure of the "external contour ring 1, the integral ring 26, and the internal contour ring 3" is lowered from top to bottom. First, the anti-rotation column 15 is passed through the main shaft hole, and then continues to descend and pass through the anti-rotation hole 16. Since the cross-section of the anti-rotation hole 16 is elliptical, even if the overall angle of the "external contour ring 1, the integral ring 26, and the internal contour ring 3" deviates, the anti-rotation hole 16 and the anti-rotation column 15 can guide the overall rotation of the "external contour ring 1, the integral ring 26, and the internal contour ring 3" to the desired angle. After the anti-rotation column 15 is attached to the inner wall of the anti-rotation hole 16, the overall structure of the "external contour ring 1, the integral ring 26, and the internal contour ring 3" is lowered.

[0056] During the descent process, the first limiting portion 2a, which is longer in length, will first enter one positioning hole 7, and then the second limiting portion 2b will enter the other positioning hole 7. In this way, the two limit portions enter separately, which facilitates normal entry.

[0057] As the assembly continues downward, the bottom of the integral ring 26 first contacts the mounting surface 6. Then, the "external ring 1, integral ring 26, and internal ring 3" are released. Then, under the action of gravity, both the external ring 1 and the internal ring 3 descend until the bottom of the external ring 1 contacts the mounting surface 6 and the bottom of the internal ring 3 contacts the flywheel housing 4. Finally, the integral ring 26 is removed via the indicator ring 27, completing the installation of the "external ring 1, integral ring 26, and internal ring 3" assembly and allowing for subsequent gluing. The entire assembly process of the "external ring 1, integral ring 26, and internal ring 3" assembly simply requires vertically lowering the "external ring 1, integral ring 26, and internal ring 3," which takes minimal time. The assembly of the "external ring 1, integral ring 26, and internal ring 3" assembly can be performed simultaneously with the gluing (the number of combined structures is greater than that of the flywheel housing 4), thus ensuring overall efficiency.

[0058] When inserting the connecting tube 9 into the spindle hole, the guide portion 11 at the bottom facilitates insertion. Furthermore, the observation hole on the connecting plate 14 allows for observation of the angle and position of the anti-rotation post 15, facilitating proper operation. Four finger holes 18 and two thumb holes 19 facilitate raising the inner contour ring 3. The tops of the outer contour ring 1 and the inner contour ring 3 are rounded or chamfered, making it easier for the gun tip to enter the guide ring.

[0059] When assembling the inner contour ring 3 and the integral ring 26, the first step is to move the terminating member 21 using the two operating parts 25 and retract it into the terminating housing 20. Afterwards, the terminating member 21 can be assembled with the integral ring 26. Furthermore, since the terminating member 21 remains retracted into the clearance hole 22 during the lowering of the inner contour ring 3, any interaction between the terminating member 21 and the outer contour ring 1 is prevented, making assembly more convenient.

[0060] When applying glue, first press the gun head against the back side of the inclined side (i.e. chamfered or rounded) of the termination piece 21 located in the guide ring, and then move the gun head in the direction away from the termination piece 21; after the gun head moves one circle, the gun head presses against the inclined side of the termination piece 21, and the gun head can drive the termination piece 21 to move into the termination shell 20 and further compress the elastic piece 23 (preferably a spring); when the gun head passes the termination piece 21, the termination piece 21 rebounds under the elastic force of the elastic piece 23, and causes the operating part 25 to hit the termination shell 20, generating a sound, reminding the construction personnel to apply glue with the glue gun for one circle, thus completing the gluing, which is simple and convenient.

[0061] After the glue is applied, the worker raises the connecting tube 9 through the operating panel 17; during the raising process, the anti-rotation column 15 continues to fit the inner wall of the anti-rotation hole 16 until the support ring 8 is higher than the glue on the mounting surface 6, and then the anti-rotation column 15 is pulled out from the anti-rotation hole 16. At this time, since the support ring 8 is higher than the glue, even if the internal contour ring 3 rotates horizontally, it will not act on the glue, thereby ensuring the stability of the glue.

[0062] During the process of raising the outer contour ring 1, since the first limiting portion 2a and the second limiting portion 2b both have a certain height, the outer contour ring 1 can be separated from the flywheel housing 4 when it is higher than the rubber, which can also better prevent the rubber from being flattened or scraped off.

[0063] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referenced to each other.

[0064] The above description is only a description of the preferred embodiments of the present invention and does not limit the scope of the present invention. Any changes and modifications made by ordinary technicians in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
