DETAILED DESCRIPTION

[0042] The drawings are only for example illustration, and can not be understood as the limitation of the patent of the utility model;

[0043] In order to better illustrate the embodiment, some components of the drawings can be omitted, enlarged or reduced, and do not represent the size of actual product;

[0044] For those skilled in the art, it is understandable that some well-known structures in the drawings and their description can be omitted;

[0045] In the description of the utility model, it is necessary to explain, unless another explicit provision and limitation, term "arrangement", "connection" should do broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, also can be electrical connection, can be direct connection, also can be indirectly connected through intermediate medium, can say two element internal communication. For ordinary skilled in the art, the above-mentioned terms can be understood in the specific meaning of the utility model according to specific circumstances. The orientation or position relationship indicated by the terms "upper", "lower", "left", "right", "front", "back" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0046] The technical scheme of the utility model will be further explained below in combination with the drawings and embodiments.

[0047] As Figure 2 The utility model example embodiment's air pump piston production guiding glueing pressure sleeve tool, it includes the guiding placement piece 11 of arrangement in rotating mechanism, the guiding sleeve pressure tool 13 of arrangement in pressure sleeve mechanism and with the guiding sleeve pressure tool sliding fit connection as a whole guiding sleeve stabilizer 12, and the glue nozzle 14 of arrangement in glueing mechanism. Wherein, the whole that guiding sleeve stabilizer 12 and guiding sleeve pressure tool 13 constitute with guiding placement piece 11 upper and lower apart coaxial arrangement;Glue nozzle 14 is located in guiding placement piece side.

[0048] The upper end surface of guiding placement piece 11 is vertically downward in the middle and has an insertion hole 112 for gap cooperation with the shaft part of guiding 4, the hole depth of the insertion hole is greater than the length of the shaft part of guiding, and can be a blind hole or a through hole. It should be noted that the upper end surface of guiding placement piece 11 is horizontal after installation to ensure horizontal contact with guiding 4, which is beneficial to maintaining good perpendicularity of guiding at all times. In some embodiments, the insertion hole 112 is a through hole that penetrates through the mounting base 111 at the lower end of the guiding placement piece 11. Specifically, the mounting base has an end surface hole for rough positioning during installation, and the insertion hole 112 is coaxially connected to the end surface hole. In addition, a plurality of screw holes are provided around the end surface hole on the mounting base, and the guiding placement piece 11 can be fixed to the rotating mechanism by screws.

[0049] In combination with Figure 4The hole wall of the above-mentioned insertion hole 112 is provided with a hole channel near the hole mouth, which includes a threaded hole on the outer hole wall and a tapered hole on the inner hole wall, and a cylindrical hole connecting the threaded hole and the tapered hole, so as to arrange the elastic fastening mechanism 113. Specifically, the elastic fastening mechanism 113 includes a steel ball 1131, a compression spring 1132 and a fastening screw 1133 arranged in the hole channel in sequence, wherein the fastening screw is screwed into the threaded hole in threaded cooperation, the end of the fastening screw abuts against the outer end of the compression spring, the inner end of the compression spring abuts against the steel ball, and the arc surface part of the steel ball exposed outside the tapered hole abuts against the shaft part of the guide 4 under the action of the spring force to achieve the fastening effect. In this way, the guide 4 can rotate / stop with the rotating mechanism, and the guide can always maintain good perpendicularity and coaxiality with the related workpiece (such as the guide sleeve 3 sleeved on the guide sleeve stabilizer 12) during the gluing (guide rotation) and the sleeve pressing (guide stop).

[0050] It can be understood that the human hand can overcome the spring force to make the steel ball 1131 adaptively retreat during the putting / taking out of the guide in the guide placing part 11, and the size of the spring force can be adjusted by rotating the fastening screw 1133 to move forward and backward.

[0051] In some embodiments, the guide sleeve pressing device 13 can be preferably processed into a structure with two coaxial cylindrical surfaces on the outer side, wherein the upper cylindrical surface has a larger diameter, which is the outer side of the installation base 131 of the guide sleeve pressing device. Six screw holes are uniformly distributed on the circumference of the installation base, and the guide sleeve pressing device 13 can be fixed to the sleeve pressing mechanism through screws. In this way, the guide sleeve pressing device can move up and down linearly with the sleeve pressing mechanism.

[0052] The central axis of the guide sleeve pressing device 13 installed on the sleeve pressing mechanism is vertical, and the lower end surface is horizontal. The inside of the guide sleeve pressing device 13 is formed with a through hollow cavity along the central axis, a baffle 132 is arranged near the upper end in the hollow cavity, and a sleeve pressing spring 133 is arranged along the central axis, and the upper end of the sleeve pressing spring abuts against the baffle.

[0053] The guide sleeve stabilizer 12 is connected with the lower end inner wall of the hollow cavity through sliding cooperation of the sliding part. The sliding part is initially exposed at the lower part so as to sleeve the guide sleeve, and the upper end surface of the guide sleeve touches the lower end surface of the guide sleeve pressing device 13 when sleeved in place, and the lower end of the sleeve pressing spring 133 abuts against the guide sleeve stabilizer 12.

[0054] It is known that the glue applying mechanism is composed of a glue nozzle 14, a glue container, a glue applying time control and pressure control system (only the end part of the glue nozzle is shown in the drawing). The end of the glue nozzle 14 is in the shape of a conical tube, the axis of which is slightly inclined downward and intersects with the axis of the guide locating member 11. Automatic control is realized by a programmable controller, so that the glue nozzle 14 is moved close to the outer surface of the proximal end face of the guiding cylinder portion and starts to apply glue when the guide rotates, and ends the glue applying and moves back to the original position when the guide stops rotating. It should be noted that the relative position of the glue nozzle and the guide can be adjusted according to the size of the guide of different specifications, and the time and pressure of glue applying can be adjusted as needed, effectively ensuring the quality of glue applying.

[0055] In some embodiments, in order to facilitate processing and molding, the hollow cavity is preferably configured to have a circular cross section, including a lower end face hole formed in the lower end face of the guide sleeve pressing tool 13, and a long through hole having a larger hole diameter than the hole diameter of the lower end face hole and being connected to the upper end of the lower end face hole. The inner wall of the hole of the lower end face hole protrudes from the inner wall of the long through hole to form an annular boss. Correspondingly, the aforementioned sliding part includes a first cylindrical section 121 which is in sliding cooperation with the long through hole, and a second cylindrical section 122 which is in sliding cooperation with the lower end face hole. The horizontal surface between the first cylindrical section and the second cylindrical section forms a limiting shoulder, which initially abuts the upper surface of the annular boss. The lower part of the second cylindrical section is exposed to facilitate the sleeving of the guide sleeve, and the outer edge of the upper end face of the guide sleeve is located within the outer edge of the lower end face of the guide sleeve pressing tool. It should be noted that the outer diameter and the initial exposed length of the second cylindrical section 122 match the inner diameter and the length of the guide sleeve 3. It can be understood that the lower end face of the guide sleeve pressing tool 13 is a circular ring, and the outer diameter of the circular ring is larger than the outer diameter of the guide sleeve, so as to ensure that the lower end face of the guide sleeve pressing tool has the largest possible contact area with the upper end face of the guide sleeve.

[0056] Further, the outer diameter of the second cylindrical section 122 is the same as the outer diameter of the cylinder portion of the guide 4. When the lower end face of the second cylindrical section 122 touches the upper end face of the guide 4 on the guide locating member 11, the guide sleeve stabilizer 12 stops moving, and the outer surface of the second cylindrical section 122 smoothly connects with the outer surface of the cylinder portion of the guide 4, facilitating the sliding of the guide sleeve 3 to the outer surface of the cylinder portion of the guide 4 under the pressing action.

[0057] In some embodiments, the lower end of the second cylindrical section 122 is coaxially formed with a third cylindrical section 123. The outer diameter of the third cylindrical section is smaller than the outer diameter of the second cylindrical section, and the outer diameter and the length of the third cylindrical section 123 are smaller than the inner diameter and the length of the cylinder portion of the guide 4, respectively. In this way, the lower end of the guide sleeve stabilizer can be roughly positioned in alignment with the guide 4 on the guide locating member through the third cylindrical section 123, and the third cylindrical section can avoid interfering with the guide during the pressing of the sleeve. The horizontal surface between the second cylindrical section 122 and the third cylindrical section 123 forms an abutting shoulder. The aforementioned touching of the lower end face of the second cylindrical section to the upper end face of the guide on the guide locating member 11 refers to the abutting shoulder touching the upper end face of the guide on the guide locating member.

[0058] In some embodiments, a blind hole is formed in the center of the upper end surface of the guide sleeve stabilizer 12, which is used to position and abut the lower end of the sleeve pressing spring 133; at the same time, a small hole diameter through hole and a large hole diameter counterbore are coaxially formed in the center of the baffle 132, and the through hole is on the upper side and the counterbore is on the lower side, which are opposite to the blind hole. The through hole is a process hole for facilitating the installation and removal of the baffle, and the counterbore is used to position and abut the upper end of the sleeve pressing spring 133.

[0059] Further, the hollow cavity further includes a circular stepped hole formed in the upper installation base 131 of the guide sleeve pressing tool 13, which includes an upper step large hole and a lower step small hole. The upper step large hole is a hole in the upper end surface of the guide sleeve pressing tool, which is used for rough positioning when the guide sleeve pressing tool is installed; the lower step small hole is in communication with the upper end of the long through hole, and the bottom of the hole is provided with two threaded holes for installing the baffle 132.

[0060] The baffle 132 can be a plate with a cylindrical shape, which can be fitted into the lower step small hole and rested on the bottom of the hole. The baffle 132 is uniformly provided with two countersunk screw holes on the circumference, which correspond to the two threaded holes on the bottom of the lower step small hole, so as to fix the baffle by screws.

[0061] It should be noted that other structures of the rotation mechanism, the sleeve pressing mechanism and the glue applying mechanism not mentioned above can refer to the prior art. The operation control (including time, movement distance, etc.) of the rotation mechanism, the sleeve pressing mechanism and the glue applying mechanism is realized by a programmable controller, which is a mature technology, and therefore will not be described in detail.

[0062] The utility model also provides a guide glue applying and sleeve pressing equipment for air pump piston production, which comprises a rotation mechanism, a sleeve pressing mechanism and a glue applying mechanism controlled and executed by a programmable controller. The rotation mechanism, the sleeve pressing mechanism and the glue applying mechanism are arranged as any one of the guide glue applying and sleeve pressing tool for air pump piston production described above. The equipment has all the beneficial effects of the guide glue applying and sleeve pressing tool provided in the above embodiments, and will not be described in detail here.

[0063] As shown in the figure, when the guide and the guide sleeve are manually placed and the equipment is started, the working process of each mechanism is as follows: Figure 3

[0064] ​The rotating mechanism drives the guide 4 to rotate (process one), the glue nozzle 14 moves close to the guide 4 and applies glue (process two); after the glue applying is finished, the glue nozzle 14 is reset, the rotating mechanism stops rotating, the sleeve pressing mechanism is actuated to move the guide sleeve pressing tool 13 and the guide sleeve stabilizer 12 together with the guide sleeve 3 downwards (process three); when the abutting shaft shoulder of the exposed part of the guide sleeve stabilizer 12 touches the guide upper end surface, the guide sleeve stabilizer 12 stops moving (process four), the guide sleeve pressing tool 13 continues to slide downwards along the outer circular surface of the second cylindrical section 122 of the guide sleeve stabilizer 12, thereby pushing the guide sleeve 3 to move downwards, and the sleeve spring 133 is compressed in this process; until the guide sleeve 3 is completely pushed to be sleeved on the outer circular surface of the cylinder part of the guide 4, that is, the upper end surface of the guide sleeve is basically flush with the upper end surface of the guide, the guide sleeve is pushed to the position (process five), the guide sleeve pressing tool 13 is moved upwards to reset with the sleeve pressing mechanism, and the guide sleeve stabilizer 12 is restored to the initial relative position with the guide sleeve pressing tool 13 under the action of the sleeve spring 133.

[0065] As above, the "glue applying-sleeve pressing" of one guide is finished, the guide with the sleeve is taken off from the guide placing part 11 by hand, and then the "glue applying-sleeve pressing" of the next guide is entered.

[0066] The above is only the preferable specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any person skilled in the art in the technical range disclosed by the utility model according to the technical scheme and the conception of the utility model for equivalent replacement or change should be covered in the protection scope of the utility model.
