Description

TECHNICAL FIELD

[0001] The utility model relates to piston production technical field especially relates to a piston head gluing and sleeve pressing tool and equipment for air pump piston production. BACKGROUND

[0002] The piston component of electromagnetic air pump (hereinafter referred to as "air pump") is composed of five parts, i.e. piston head, piston plastic sleeve (hereinafter referred to as "piston sleeve"), guide (hereinafter referred to as "guide"), guide plastic sleeve (hereinafter referred to as "guide sleeve") and iron core. The combined production of the piston component includes: smearing adhesive (hereinafter referred to as "gluing"), combined plastic sleeve (usually realized by using pressure, hereinafter referred to as "sleeve pressing") and final combination. Referring to the attached Figure 1 , specifically, three processes (such as the A, B and C of the attached Figure 1 ) and seven steps are needed: ① gluing on the piston head 2; ② pressing the piston sleeve 1 into the piston head 2 (so as to become a sleeved piston head); ③ gluing on the cylinder part of the guide 4; ④ pressing the guide sleeve 3 into the guide 4 (so as to become a sleeved guide); ⑤ putting the iron core 5 on the shaft part of the guide 4; ⑥ gluing again on the shaft part of the guide 4; ⑦ then pressing the sleeved piston head and the sleeved guide with the iron core 5 together (realized by using pressure for combination).

Because the gluing is realized by hand, the amount of adhesive is not too much or too little, and the thickness of the adhesive is not uniform; because the sleeve pressing is realized by hand, the labor intensity is large, and the verticality of the sleeve pressing is poor, which leads to damage or adhesive residue of the plastic sleeve; because the sleeve pressing or combination needs to be preceded by gluing, and the adhesive on the part will solidify in a short time, the next step needs to be performed immediately, which leads to the fact that a single person cannot complete the "gluing-sleeve pressing" or "gluing-combination", and at least two persons are needed to complete the work, and the working rhythm of different persons is difficult to coordinate, which leads to the problem that the working efficiency is restricted.

DETAILED DESCRIPTION

[0045] The drawings are only for illustrative purposes and should not be construed as limiting the patent;

[0046] In order to better illustrate the embodiment, some components in the drawings may be omitted, enlarged or reduced, and do not represent the actual product size;

[0047] It is understandable for those skilled in the art that some well-known structures and their descriptions in the drawings may be omitted;

[0048] In the description of the utility model, it is necessary to explain that, unless there is definite stipulation and limitation, the term "arrange", "connect" should be 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 be said that the communication of two elements inside. For ordinary skilled in the art, the above-mentioned term can be understood in the specific meaning of the utility model according to specific circumstances. The orientation or position relation indicated by the terms "upper", "lower", "left", "right", "front", "rear" etc. are based on the orientation or position relation shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as limiting the utility model.

[0049] The technical scheme of the utility model will be further explained below in combination with the drawings and embodiments.

[0050] As Figure 2 The piston head glue coating and sleeve pressing tool of the exemplary embodiment of the utility model comprises a piston head placing piece 11 arranged in a rotating mechanism, a piston sleeve pressing tool 13 arranged in a sleeve pressing mechanism and a piston sleeve stabilizing piece 12 integrally connected with the piston sleeve pressing tool in sliding cooperation, and a glue outlet 14 arranged in a glue coating mechanism. The piston sleeve stabilizing piece 12 and the piston sleeve pressing tool 13 constitute a whole which is arranged coaxially above and below the piston head placing piece 11. The glue outlet 14 is located beside the piston head placing piece.

[0051] In some embodiments, a blind hole is vertically downwardly formed in the middle of the upper end surface of the piston head placing piece 11, the hole depth is greater than the length of the handle portion of the piston head 2, a cylindrical first protrusion 111 is formed in the middle of the hole bottom in the blind hole, which is used for fitting and inserting the handle portion inner hole of the piston head, and can realize the center positioning of the piston head. A cylindrical second protrusion 112 is also formed in the upper end surface of the piston head placing piece 11, which is used for fitting and inserting the air hole of the piston portion counterbore bottom surface of the piston head, and can realize the circumferential positioning of the piston head. In this way, the piston head 2 can rotate / stationary with the rotating mechanism, and the piston head can always maintain good perpendicularity and coaxiality with the related workpiece (such as the piston sleeve 1 sleeved on the piston sleeve stabilizing piece 12) during the glue coating (in the rotating state of the piston head) and the sleeve pressing (in the stationary state of the piston head).

[0052] The upper end surface of the piston head placing piece 11 except the second protrusion 112 is horizontal, so as to ensure the horizontal contact with the piston head 2, and facilitate the piston head to always maintain good perpendicularity.

[0053] The piston head placing part 11 can be fixed to the rotating mechanism through the mounting base 113 at its lower end, and specifically, a plurality of screw holes are formed on the mounting base, and the piston head placing part can be fixed to the rotating mechanism through screws.

[0054] As shown in Figure 5 , the piston sleeve pressing device 13 can be preferably processed into a structure with two coaxial cylindrical surfaces on its outer side, wherein the upper cylindrical surface has a larger diameter, which is the outer side of the installation base 131 of the piston sleeve pressing device, and six screw holes are uniformly distributed on the circumference of the installation base, and the piston sleeve pressing device 13 can be fixed to the sleeve pressing mechanism through screws, so that the piston sleeve pressing device can move up and down linearly with the sleeve pressing mechanism.

[0055] The piston sleeve pressing device 13 installed on the sleeve pressing mechanism has a vertical central axis and a horizontal lower end surface. A through hollow cavity is formed in the piston sleeve pressing device 13 along the central axis, and a baffle 132 is arranged near the upper end of the hollow cavity along the central axis, and a sleeve pressing spring 133 is arranged along the central axis.

[0056] The piston sleeve stabilizing part 12 is connected to the inner wall of the lower end of the hollow cavity through a sliding part, which is initially exposed at the lower part to facilitate the installation of the piston sleeve, and after the installation is completed, the upper end surface of the piston sleeve touches the lower end surface of the piston sleeve pressing device 13, and the lower end of the sleeve pressing spring 133 abuts against the piston sleeve stabilizing part 12.

[0057] It is known that the glue applying mechanism is composed of a glue outlet nozzle 14, a glue container, a glue outlet time control system and a pressure control system (only the end part of the glue outlet nozzle is shown in the figure). The end of the glue outlet nozzle 14 is in the shape of a conical tube, and its axis is slightly inclined downward and intersects with the axis of the piston head placing part 11. Through automatic control by a programmable controller, the glue outlet nozzle 14 moves close to the outer surface of the proximal end of the piston part of the piston head after the rotation of the piston head and starts to apply glue, and ends the glue application and moves back to the original position when the piston head stops rotating. It should be noted that the relative position of the glue outlet nozzle and the piston head can be adjusted according to the size of the piston head of different specifications, and the time and pressure of glue application can be adjusted as needed, effectively ensuring the quality of glue application.

[0058] As shown in Figure 2 , Figure 5 , the cross section of the hollow cavity is circular, including a lower end surface hole formed on the lower end surface of the piston sleeve pressing device 13, and a long through hole with a larger hole diameter than the lower end surface hole and connected to the upper end thereof, and the hole inner wall of the lower end surface hole is protruded from the hole inner wall of the long through hole to form an annular boss. As shown in Figure 2 , Figure 4As shown in the drawings, the sliding part described above comprises a first cylindrical segment 121 which is in sliding fit with the long through hole, and a second cylindrical segment 122 which is in sliding fit with the lower end face hole. The horizontal plane between the first cylindrical segment and the second cylindrical segment forms a limiting shoulder. Initially, the limiting shoulder is attached to the upper surface of the annular boss. The lower part of the second cylindrical segment is exposed so as to be sleeved with the piston sleeve. The outer edge of the upper end face of the piston sleeve is located within the outer edge of the lower end face of the piston sleeve press. It should be noted that the outer diameter and the initial exposed length of the second cylindrical segment 122 match the inner diameter and the length of the piston sleeve 1. It can be understood that the lower end face of the piston sleeve press 13 is a circular ring, and the outer diameter of the circular ring is greater than the outer diameter of the piston sleeve, so as to ensure that the lower end face of the piston sleeve press has the largest possible contact area with the upper end face of the piston sleeve.

[0059] Further, the outer diameter of the second cylindrical segment 122 is the same as the outer diameter of the piston part of the piston head 2. When the lower end face of the second cylindrical segment 122 contacts the upper end face of the piston head 2 on the piston head mounting member 11, the piston sleeve stabilizer 12 stops moving, the outer circular surface of the second cylindrical segment 122 smoothly connects with the outer circular surface of the piston part of the piston head 2, and the piston sleeve 1 is facilitated to slide onto the outer circular surface of the piston part of the piston head 2 under the pressing action.

[0060] In some embodiments, the lower end of the second cylindrical segment 122 is further coaxially formed with a third cylindrical segment 123. The outer diameter of the third cylindrical segment is smaller than the outer diameter of the second cylindrical segment. The outer diameter and the length of the third cylindrical segment 123 are respectively smaller than the hole diameter and the hole depth of the piston part counterbore of the piston head 2. In this way, the lower end of the piston sleeve stabilizer can be roughly positioned in alignment with the piston head 2 on the piston head mounting member through the third cylindrical segment 123, and the third cylindrical segment can be prevented from interfering with the piston head during the pressing of the sleeve. The horizontal plane between the second cylindrical segment 122 and the third cylindrical segment 123 forms an abutting shoulder. The lower end face of the second cylindrical segment contacting the upper end face of the piston head on the piston head mounting member 11 refers to the abutting shoulder contacting the upper end face of the piston head on the piston head mounting member.

[0061] As shown in the drawings, Figure 4 , Figure 6 The upper end face of the piston sleeve stabilizer 12 is provided with a blind hole in the center. The blind hole is used to position and abut against the lower end of the sleeve pressing spring 133. At the same time, the center of the baffle 132 is coaxially provided with a small-diameter through hole and a large-diameter counterbore which are connected in communication. The through hole is above, and the counterbore is below and opposite to the blind hole. The through hole is a process hole for facilitating the installation and removal of the baffle. The counterbore is used to position and abut against the upper end of the sleeve pressing spring 133.

[0062] Further, the hollow cavity further comprises a circular stepped hole formed in the upper part mounting base 131 of the piston sleeve press 13. The stepped hole comprises an upper large hole and a lower small hole. The upper large hole is the upper end face hole of the piston sleeve press, which is used for rough positioning during the installation of the piston sleeve press. The lower small hole is in communication with the upper end of the long through hole, and the hole bottom is provided with two threaded holes for installing the baffle 132.

[0063] As Figure 6 shown, the baffle 132 can preferably be a plate with a cylindrical shape, which can be fitted into the lower small hole and placed on the hole bottom, and two countersunk screw holes are uniformly distributed on the circumference of the baffle 132, which are one-to-one corresponding to the two threaded holes on the hole bottom of the lower small hole, so as to fix the baffle through the screws.

[0064] It should be noted that other structures not described about the rotating mechanism, the sleeve pressing mechanism and the glue applying mechanism can refer to the prior art; the operation control (including time, moving distance, etc.) of the rotating mechanism, the sleeve pressing mechanism and the glue applying mechanism is realized through the programmable controller, which is a mature technology, and thus will not be described in detail.

[0065] The utility model also provides a piston head glue applying and sleeve pressing equipment for piston production, which comprises a rotating mechanism, a sleeve pressing mechanism and a glue applying mechanism controlled and executed by a programmable controller, wherein the rotating mechanism, the sleeve pressing mechanism and the glue applying mechanism are arranged as any one of the piston head glue applying and sleeve pressing tooling for piston production described above.

[0066] As Figure 3 shown, when the piston head and the piston sleeve are manually placed and the equipment is started, the working processes of the mechanisms are as follows:

[0067] The rotating mechanism drives the piston head 2 to rotate (process one), the glue nozzle 14 moves close to the piston head 2 and applies glue (process two); after the glue applying is completed, the glue nozzle 14 is reset, the rotating mechanism stops rotating, and the sleeve pressing mechanism moves the piston sleeve pressing tool 13 and the piston sleeve stabilizer 12 together with the piston sleeve 1 downward (process three); when the abutting shaft shoulder of the exposed part of the piston sleeve stabilizer 12 touches the upper end surface of the piston head, the piston sleeve stabilizer 12 stops moving (process four), and the piston sleeve pressing tool 13 continues to slide downward along the outer circular surface of the second cylindrical segment 122 of the piston sleeve stabilizer, so as to press and push the piston sleeve 1 to move downward, and in this process, the sleeve pressing spring 133 is compressed; until the piston sleeve 1 is completely pressed and pushed to be sleeved on the outer circular surface of the piston part of the piston head 2, that is, the upper end surface of the piston sleeve is basically flush with the upper end surface of the piston head, the piston sleeve is pressed and pushed to the position (process five), the piston sleeve pressing tool 13 is moved upward to reset with the sleeve pressing mechanism, and the piston sleeve stabilizer 12 is restored to the initial relative position with the piston sleeve pressing tool 13 under the action of the sleeve pressing spring 133.

[0068] As described above, the “glue applying and sleeve pressing” of one piston head is completed. The sleeved piston head is taken off from the piston head placing part 11 by hand, and then enters the “glue applying and sleeve pressing” of the next piston head.

[0069] The above merely describes preferred embodiments of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and concept of the present application, can make equivalent substitutions or changes within the technical range disclosed by the present application, which should be encompassed in the protection scope of the present application.
