Description

Technical Field

[0001] This utility model relates to the field of stud installation technology, and specifically to a stud installation device. Background Technology

[0002] As is well known, double-ended studs are widely used in fields such as power, bridges, and machinery. In some large equipment, accessories such as mechanical seal seats and reducer frames need to be installed. In this case, double-ended studs are used. One end is screwed into the main body, and after the accessory is installed, the other end is fitted with a nut.

[0003] Since double-ended studs have threads at both ends but no threads in the middle, the middle is a smooth stalk. Most installations of double-ended studs involve clamping the smooth stalk with pliers to screw it into the main body, which can easily result in insufficient installation torque and low installation efficiency. Therefore, this invention designs a stud installation device that allows for quick installation of double-ended studs using an electric wrench and socket, thus improving installation efficiency. Utility Model Content

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, the purpose of this invention is to provide a stud installation device to solve the technical problem of low installation efficiency of double-ended studs.

[0005] This utility model is achieved through the following technical solution:

[0006] A stud mounting device includes a pressure plate, a threaded seat, and a ball bearing. The threaded seat has an axially penetrating cavity, which includes a wide circular cavity, a ball cavity, and a narrow circular cavity. The side wall of the pressure plate is threadedly connected to the wide circular cavity. The ball bearing is fitted into the ball cavity. After the ball bearing is placed into the ball cavity, the pressure plate is rotated until its bottom secures the ball bearing. The narrow circular cavity is threadedly connected to one end of a double-ended stud. The threaded seat is rotated until one end of the double-ended stud is pressed against the ball bearing. The other end of the double-ended stud is threadedly connected to a threaded hole on the base plate.

[0007] Preferably, the top of the pressure plate has a groove for use with a screwdriver.

[0008] Preferably, the dimensions of the cavity inside the threaded seat and the ball bearings are adapted to the dimensions of the double-ended stud to be installed.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This invention constructs a threaded seat with an internal cavity that runs through it axially. It is fitted with a pressure plate and ball bearings. By using an electric wrench and a socket, the threaded seat can be rotated quickly. This allows the ball bearings at one end of the double-ended stud to be pressed against the tooling to achieve a locking state. The double-ended stud then rotates with the entire device. Finally, the lower end of the double-ended stud is quickly screwed into the base plate, thus improving the installation efficiency of the double-ended stud. Attached Figure Description

[0011] To more clearly illustrate the technical solutions of the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0013] Figure 2 This is a cross-sectional view of the threaded seat of this utility model;

[0014] Figure 3 This is a schematic diagram of the structure of the pressure plate of this utility model.

[0015] Among them, pressure plate 1, groove 101, threaded seat 2, wide round cavity 201, ball cavity 202, narrow round cavity 203, ball ball 3, double-ended stud 4, and base plate 5. Detailed Implementation

[0016] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings. Figures 1-2A stud mounting device is shown, including a pressure plate 1, a threaded seat 2, and a ball bearing 3. The threaded seat 2 has an axially penetrating cavity, which includes a wide circular cavity 201, a ball cavity 202, and a narrow circular cavity 203. The side wall of the pressure plate 1 is threadedly connected to the wide circular cavity 201. The ball bearing 3 is fitted into the ball cavity 202. After the ball bearing 3 is placed into the ball cavity 202, the pressure plate 1 is rotated until the bottom of the ball bearing 3 is secured. The narrow circular cavity 203 is threadedly connected to one end of a double-ended stud 4. The threaded seat 2 is rotated until one end of the double-ended stud 4 is pressed against the ball bearing 3. When the upper end of the double-ended stud 4 contacts and is pressed against the ball bearing 3, friction is generated, and one end of the double-ended stud 4 is locked to the fixture. The double-ended stud 4 rotates with the entire device. Since the other end of the double-ended stud 4 is threadedly connected to the screw hole on the base plate 5, the lower end of the double-ended stud 4 is finally screwed into the base plate 5.

[0018] To facilitate the rotation of pressure plate 1, such as Figure 3 A groove 101 for use with a screwdriver is reserved at the top of the pressure plate 1. After inserting the screwdriver into the groove 101, screw it in until the bottom of the pressure plate 1 presses against the ball 3.

[0019] The internal cavity of the threaded seat 2 and the dimensions of the ball bearing 3 are designed to fit the dimensions of the stud 4 to be installed. Different specifications of stud 4 can be accommodated by changing the dimensions of the pressure plate 1, threaded seat 2, and ball bearing 3. The threaded seat 2 should preferably be made of steel with good heat treatment properties and high quenching hardness to ensure high thread strength and increase the service life of the threaded seat 2.

[0020] This device adopts a modular structure, meaning that if one part fails, only the damaged part needs to be replaced, greatly improving the device's cost-effectiveness. After repeated assembly and use, this invention has proven to have stable performance and significantly improved installation efficiency, making it worthy of promotion within the industry.

[0021] The working principle of this utility model:

[0022] Quickly install the double-ended stud 4 onto the base 5 in two steps as follows:

[0023] Since the threaded seat 2 is threadedly connected to the double-ended stud 4, the threaded seat 2 can be rotated quickly by using an electric wrench and socket. The upper end of the double-ended stud 4 is quickly screwed into the threaded seat 2. When the upper end of the double-ended stud 4 comes into contact with the ball 3 and is squeezed, friction is generated. One end of the double-ended stud 4 is locked to the tooling. The double-ended stud 4 will rotate with the entire device. Finally, the lower end of the double-ended stud 4 is quickly screwed into the base plate 5.

[0024] After the double-ended stud 4 is installed, the electric wrench is set to reverse, and the socket drives the tooling to follow the reverse rotation. The ball 3 and the double-ended stud instantly change from a squeezed state to a separated state. Since the ball 3 is a smooth spherical surface, the friction can be ignored. The threaded seat 2 rotates quickly with the electric wrench and socket and quickly retracts.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
