Description

TECHNICAL FIELD

[0001] The application relates to the technical field of rivet processing molds, in particular to an automatic rivet mold for externally placing rivets. BACKGROUND

[0002] In today's life, a rivet is a nail-shaped object for connecting two parts (or components) with holes and a cap at one end. In riveting, the rivet is used to connect the parts to be riveted by deforming itself or interference. There are many types of rivets, and the forms are not limited. From aerospace to office machines, electronic products and sports field equipment, it can be said that such blind rivets have become an effective and stable mechanical connection method.

[0003] Generally, the end of the rivet needs to be polished to remove burrs after stamping. The existing processing mold mainly uses limiting bolts or air cylinders, which can basically limit a single rivet at a time, reducing the overall processing efficiency.

[0004] Therefore, the person skilled in the art provides an automatic rivet mold for externally placing rivets to solve the problems in the background art. CONTENT OF THE INVENTION

[0005] In order to solve the problems in the background art, the application provides an automatic rivet mold for externally placing rivets.

[0006] The automatic rivet mold for externally placing rivets provided by the application adopts the following technical scheme:

[0007] An automatic rivet mold for externally placing rivets comprises a mounting plate, a processing table is mounted on the upper surface of the mounting plate, supporting plates are mounted on both sides of the upper surface of the processing table, a main shaft rod is rotatably connected between the two supporting plates, a plurality of double-threaded rod sleeves are fixedly sleeved on the outer part of the main shaft rod at equal intervals, threaded sleeves are screw-driven on both ends of the outer part of the double-threaded rod sleeve, the lower surface of the threaded sleeve is attached to the upper surface of the processing table, tiger tooth plates are mounted on both sides of the outer part of the threaded sleeve, a drive motor is mounted on the side surface of one of the supporting plates, and the output end of the drive motor is fixedly connected to the corresponding end of the main shaft rod.

[0008] Preferably, two guide rods are symmetrically arranged between the side surfaces of the two supporting plates, and the guide rods penetrate one end of all the tiger tooth plates on the same side.

[0009] Preferably, a limiting ring is fixedly sleeved on both ends of the outer part of the double-threaded rod sleeve.

[0010] Preferably, a pad plate is mounted on both sides of the upper surface of the processing table, and a plurality of rivet barrels are distributed on the upper surface of the pad plate at equal intervals.

[0011] Preferably, each rivet barrel is arranged at the center of the two tiger tooth plates on a single double-threaded rod sleeve.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] 1. By driving the motor to rotate the main shaft rod, the multiple bidirectional screw rod sleeves are driven to rotate, so that the threaded sleeves at both ends of the bidirectional screw rod sleeves and the two side jaw plates move towards each other to tightly abut the two sides of the vertically placed rivets, thereby achieving batch and simultaneous positioning of multiple rivets at one time, effectively improving the efficiency of the mold during processing.

[0014] 2. The multiple rivets can be kept in a vertical state before being positioned, which is convenient for subsequent concentrated positioning. BRIEF DESCRIPTION OF DRAWINGS

[0019] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] Reference Figure 1 and Figure 2 as well as Figure 3As shown, this application discloses an automatic rivet mold with external rivet placement. A processing table 6 is installed on the upper surface of the mounting plate 5. The mounting plate 5 has threaded holes at the four corners to facilitate installation on the support table. Support plates 2 are installed on both sides of the upper surface of the processing table 6. A main shaft 4 is rotatably connected between the sides of the two support plates 2. Multiple bidirectional screw sleeves 8 are fixedly sleeved at equal intervals on the outside of the main shaft 4. Threaded sleeves 11 are screwed at both ends of the bidirectional screw sleeves 8. The lower surface of the threaded sleeves 11 is attached to the upper surface of the processing table 6. Tooth plates 3 are installed on both sides of the threaded sleeves 11. A drive motor 1 is installed on the side of one support plate 2, and the output end of the drive motor 1 is fixed to the corresponding end of the main shaft 4.

[0021] The output of the drive motor 1 can drive the main shaft 4 to rotate. Then, the rotating main shaft 4 drives multiple bidirectional lead screw sleeves 8 to rotate, causing the threaded sleeves 11 at both ends of the bidirectional lead screw sleeves 8 to move towards each other. Then, the two sides of the tiger tooth plates 3 move towards each other synchronously until they are in close contact with the sides of the vertically placed rivets, so that multiple rivets can be batch-limited at one time.

[0022] Reference image Figure 3 As shown, two guide rods 9 are symmetrically arranged between the two support plates 2 on the sides of the mold, and the guide rods 9 pass through one end of all the tiger tooth plates 3 on the same side, ensuring that the tiger tooth plates 3 on both sides can move linearly and stably along the guide rods 9, further improving the stability of the tiger tooth plates 3 on both sides during use.

[0023] refer to Figure 3 As shown, both ends of the bidirectional lead screw sleeve 8 in the mold are fixedly fitted with limiting rings 10. The limiting rings 10 can conveniently limit the maximum range of the opposite movement of the two threaded sleeves 11 on a single bidirectional lead screw sleeve 8, so as to avoid the separation between the threaded sleeves 11 and the bidirectional lead screw sleeve 8, which would affect the normal use of the mold.

[0024] refer to Figure 3 As shown, both sides of the upper surface of the processing table 6 in the mold are equipped with pads 7. Multiple nail cylinders 12 are evenly distributed on the upper surface of the pads 7. The multiple nail cylinders 12 can keep multiple rivets in a vertical state before they are limited, which is convenient for subsequent centralized limiting.

[0025] refer to Figure 3 As shown, each nail cylinder 12 in the mold is distributed at the center of two toothed plates 3 on a single bidirectional lead screw sleeve 8, which makes it convenient for the single bidirectional lead screw sleeve 8 to drive the opposing toothed plates 3 to effectively limit the rivets inserted inside the nail cylinder 12 when rotating.

[0026] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] The implementation principle of an automatic rivet mold with an externally mounted rivet in this application embodiment is as follows:

[0029] During processing, the workers can first insert the bottom of the rivets to be processed into the rivet tube 12 in sequence, so that multiple rivets can be kept in a vertical position before being limited, which is convenient for subsequent centralized limiting.

[0030] After placing multiple rivets, the drive motor 1 can be started, so that the output end of the drive motor 1 can drive the main shaft 4 to rotate. Then, the rotating main shaft 4 drives multiple bidirectional lead screw sleeves 8 to rotate, so that the threaded sleeves 11 at both ends of the bidirectional lead screw sleeves 8 move towards each other. Then, the two sides of the tiger tooth plate 3 move towards each other synchronously until they are in close contact with the two sides of the vertically placed rivets. Thus, multiple rivets can be batch-limited at the same time, which effectively improves the efficiency of the mold during processing.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
