Description

Technical Field

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

[0002] Stud welding equipment refers to welding equipment that brings a metal stud or similar part into contact with the surface of a workpiece, and welds the entire end face onto the workpiece through instantaneous pressure and discharge. The welding mechanism of stud welding equipment needs to be raised and lowered relative to the worktable. When the welding mechanism is raised, in order to prevent it from falling accidentally, a brake device is usually required to lock the welding mechanism in a safe position.

[0003] Brake devices typically include a telescopic brake head and a brake rod fixed to a welding mechanism.

[0004] In related technologies, the brake head of the brake device frequently comes into contact with the brake rod, which is prone to wear, resulting in a shortened service life. Furthermore, the locking is unstable and prone to jamming, which in turn leads to equipment failure and low production efficiency. Utility Model Content

[0005] In view of this, the present invention provides a brake device and stud welding equipment to solve the problem that the brake head is prone to wear and jamming.

[0006] In a first aspect, this utility model provides a brake device, comprising:

[0007] The brake arm extends along a first direction, and a portion of the brake arm is recessed along a second direction to form a neck. The second direction is not parallel to the first direction.

[0008] The brake head and the drive unit are adapted to drive the brake head to move in a second direction. The brake head has a locked state that abuts against the neck and an unlocked state that disengages from the neck in the second direction. In the unlocked state, the brake lever is adapted to move freely relative to the brake head.

[0009] Beneficial effects: When the brake head is locked, it abuts against the neck. On one hand, the friction between the brake head and the neck effectively prevents movement of the brake lever. On the other hand, because the cross-sectional area of ​​the neck is smaller than that of the main body, forming a groove, the brake head is embedded in this groove. When the brake lever moves against friction, the brake head is restricted by the limiting surfaces on both sides of the groove, further enhancing the locking effect and preventing accidental movement of the brake lever. This avoids the risk of accidental movement of the brake lever under external force and reduces the increased wear on the brake head caused by frictional movement between the brake head and the brake lever, thus reducing frictional loss. This significantly extends the service life of the brake head, reduces the equipment failure rate, and improves the stability of the braking process.

[0010] In one optional embodiment, the portion of the brake lever other than the neck is the main body, and the end face of the neck connected to the main body in the first direction forms a limiting surface.

[0011] The brake head is designed to abut against the limiting surface.

[0012] In one alternative embodiment, the drive unit includes a drive body and an output shaft, the output shaft being adapted to be moved by the drive body, and the brake head being disposed at the end of the output shaft away from the drive body.

[0013] Beneficial effects: By transmitting power through the output shaft, the displacement of the brake head is precisely controlled, ensuring stable and reliable switching between locked and unlocked states, and further improving the safety and durability of the equipment.

[0014] In one alternative embodiment, the neck has a cylindrical cross-section perpendicular to the first direction, and the end face of the brake head facing the neck is a plane.

[0015] Beneficial effects: When the cross-sectional structure of the neck is cylindrical in the direction perpendicular to the first direction and the end face of the brake head facing the neck is flat, the contact area between the two is line contact with a small contact area, which can effectively avoid the problem of the brake rod and the brake head getting stuck, reduce the frequency of failures, improve equipment reliability, and improve the production efficiency of stud welding equipment.

[0016] In one alternative implementation, the end face of the brake head facing the neck forms an abutment groove.

[0017] Beneficial effects: The end face of the brake head facing the neck forms an abutment groove. The abutment groove is groove-shaped and has two line contact areas with the cylindrical surface of the neck, thereby increasing the contact area, dispersing pressure, further reducing friction loss, extending the service life of the brake head, and ensuring long-term stable operation of the equipment.

[0018] In one alternative embodiment, the neck is constructed as a polygon in cross-section perpendicular to the first direction, and the abutment groove matches the polygon.

[0019] Beneficial effects: By matching the abutment groove with the polygon to form multi-point contact, the stress distribution on the contact surface is further optimized, local stress concentration is reduced, the wear of the brake head and the neck is effectively reduced, the service life of the equipment is extended, maintenance costs are reduced, the reliable operation of the equipment under high load conditions is ensured, and the overall work efficiency is improved.

[0020] In one optional embodiment, the brake head includes a first brake head and a second brake head, which are respectively disposed on both sides of the neck along the second direction;

[0021] The brake device also includes a reverse drive assembly connected between the first brake head and the second brake head, and adapted to drive the first brake head and the second brake head to move in opposite directions.

[0022] Beneficial effects: By setting two brake heads, with the first and second brake heads respectively positioned on both sides of the neck along the second direction, the first and second brake heads move in opposite directions under the drive of the reverse drive component, achieving bidirectional clamping of the neck, enhancing the locking force, and ensuring the stability and safety of the equipment under different operating conditions. Simultaneously, bidirectional clamping avoids the brake rod's tendency to deform under stress when clamped on one side, ensuring balanced force on the brake rod, extending its service life, and further improving the equipment's impact resistance.

[0023] In one alternative implementation, the reverse drive component includes:

[0024] The first rack is connected to the first brake head;

[0025] The second rack is connected to the second brake head;

[0026] An intermediate gear is positioned between the first rack and the second rack, and meshes with both simultaneously.

[0027] The driving component drives one of the first brake head and the second brake head.

[0028] Beneficial effects: By setting a reverse drive assembly between the first and second brake heads and using a drive component as a power source, the synchronous reverse movement of the first and second brake heads is achieved, thereby ensuring the synchronicity and coordination of the brake device and saving energy consumption. It also ensures precise synchronization of movement and meets the centering requirements.

[0029] In one alternative embodiment, the brake device further includes a buffer disposed on the limiting surface.

[0030] Beneficial effects: By further adding buffer components to the limit surface, a buffering effect can be provided when the brake head moves to the extreme position, reducing impact force, protecting the structural integrity of the neck and brake head, avoiding damage caused by violent collisions, reducing wear on the limit surface of the brake head, reducing operating noise, and further improving the stability and safety of equipment operation.

[0031] Secondly, this utility model also provides a stud welding device, comprising:

[0032] Stud welding equipment body;

[0033] The welding unit is adapted to move relative to the stud welding equipment body;

[0034] And as described above, the brake device, wherein the brake rod of the brake device is adapted to be connected to the welding unit.

[0035] Since the stud welding equipment includes a brake device, which has the same effect as the brake device, it will not be described in detail here. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0052] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0053] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0054] According to an embodiment of the present invention, a brake device is provided, comprising:

[0055] The brake lever 1 extends along a first direction, and a portion of the brake lever 1 is recessed along a second direction to form a neck 11. The second direction is not parallel to the first direction.

[0056] The brake head 2 and the drive member 3 are adapted to drive the brake head 2 to move in a second direction. The brake head 2 has a locked state that abuts against the neck 11 and an unlocked state that disengages from the neck 11 in the second direction. In the unlocked state, the brake lever 1 is adapted to move freely relative to the brake head 2.

[0057] In this embodiment, the brake rod 1 extends along a first direction, and when the stud welding equipment is in operation, the brake rod 1 is adapted to move along the first direction.

[0058] The second direction is not parallel to the first direction. In this embodiment, the second direction can be perpendicular to the first direction.

[0059] A portion of the brake lever 1 is recessed along the second direction to form a neck 11, combined with Figure 1 As shown, in a plane perpendicular to the first direction, the cross-sectional area of ​​the neck 11 is smaller than the cross-sectional area of ​​other parts of the brake lever 1.

[0060] In some embodiments, the portion of the brake lever 1 other than the neck 11 is the main body 12, and the end face of the neck 11 connected to the main body 12 in the first direction forms a limiting surface 13.

[0061] The brake head 2 is adapted to abut against the limiting surface 13.

[0062] Under the action of the drive unit 3, the brake head 2 can precisely control its relative position with the neck 11, ensuring stable switching between locked and unlocked states.

[0063] When the brake head 2 is in the locked state, it abuts against the neck 11. On one hand, the friction between the brake head 2 and the neck 11 effectively prevents the brake lever 1 from moving. On the other hand, since the cross-sectional area of ​​the neck 11 is smaller than that of the main body 12, forming a groove, the brake head 2 is embedded in this groove. When the brake lever 1 moves against friction, the brake head 2 is restricted by the limiting surfaces 13 on both sides of the groove, further enhancing the locking effect and preventing accidental movement of the brake lever 1. This avoids the risk of accidental movement of the brake lever 1 under external force and reduces the wear on the brake head 2 caused by frictional movement between the brake head 2 and the brake lever 1, thus reducing frictional loss. This significantly extends the service life of the brake head 2, reduces the equipment failure rate, and improves the stability of the braking process.

[0064] When the brake head 2 is in the unlocked state, the brake head 2 separates from the neck 11, and the brake lever 1 can move freely in the first direction. At this time, the drive component 3 retracts, and the unlocking process is smooth and rapid, ensuring that the equipment is operated flexibly and efficiently.

[0065] In some embodiments, the drive unit 3 includes a drive body 31 and an output shaft 32, the output shaft 32 being adapted to move under the drive body 31, and the brake head 2 being disposed at one end of the output shaft 32 away from the drive body 31.

[0066] The drive unit 3 can be a motor or a hydraulic cylinder, which transmits power through the output shaft 32 to precisely control the displacement of the brake head 2, ensuring stable and reliable switching between the locking and unlocking states, and further improving the safety and durability of the equipment.

[0067] In some embodiments, combined with Figure 3 As shown, the neck 11 has a cylindrical cross-section perpendicular to the first direction, and the end face of the brake head 2 facing the neck 11 is a plane.

[0068] When the neck 11 has a cylindrical cross-section perpendicular to the first direction and the end face of the brake head 2 facing the neck 11 is a plane, the contact area between the two is a line contact with a small contact area, which can effectively avoid the problem of the brake rod 1 and the brake head 2 getting stuck, reduce the frequency of failures, improve equipment reliability, and improve the production efficiency of the stud welding equipment.

[0069] In other embodiments, combined with Figure 4 As shown, the end face of the brake head 2 facing the neck 11 forms an abutment groove 21.

[0070] The end face of the brake head 2 facing the neck 11 forms an abutment groove 21. The abutment groove 21 is groove-shaped and has two line contact areas with the cylindrical surface of the neck 11, thereby increasing the contact area, dispersing pressure, further reducing friction loss, extending the service life of the brake head 2, and ensuring long-term stable operation of the equipment.

[0071] In other embodiments, combined with Figure 6 As shown, the neck 11 has a polygonal cross-section perpendicular to the first direction, and the abutment groove 21 matches the polygon.

[0072] In this embodiment, the neck 11 has a polygonal cross-section perpendicular to the first direction. By matching the abutment groove 21 with the polygon, multi-point contact is formed, which further optimizes the force distribution of the contact surface, reduces local stress concentration, effectively reduces the wear of the brake head 2 and the neck 11, extends the service life of the equipment, reduces maintenance costs, ensures the reliable operation of the equipment under high load conditions, and improves the overall work efficiency.

[0073] In other embodiments, combined with Figure 5 As shown, the brake head 2 includes a first brake head 201 and a second brake head 202, which are respectively disposed on both sides of the neck 11 along the second direction.

[0074] The brake device also includes a reverse drive assembly 4, which is connected between the first brake head 201 and the second brake head 202 and is adapted to drive the first brake head 201 and the second brake head 202 to move in opposite directions.

[0075] By setting two brake heads 2, with the first brake head 201 and the second brake head 202 respectively located on both sides of the neck 11 along the second direction, the first brake head 201 and the second brake head 202 are driven by the reverse drive component 4 to move in opposite directions, thereby achieving bidirectional clamping of the neck 11, enhancing the locking force, and ensuring the stability and safety of the equipment under different working conditions.

[0076] Meanwhile, bidirectional clamping avoids the situation where the brake lever 1 is easily deformed by force when clamped on one side, ensuring that the brake lever 1 is subjected to balanced force, extending its service life, and further improving the equipment's impact resistance.

[0077] In some embodiments, the reverse drive component 4 includes:

[0078] The first rack 41 is connected to the first brake head 201;

[0079] The second rack 42 is connected to the second brake head 202;

[0080] An intermediate gear 43 is disposed between the first rack 41 and the second rack 42, and meshes with both of them simultaneously;

[0081] The drive unit 3 drives one of the first brake head 201 and the second brake head 202.

[0082] By setting a reverse drive assembly 4 between the first brake head 201 and the second brake head 202, and using a drive component 3 as a power source, the first brake head 201 and the second brake head 202 can move synchronously in opposite directions, thereby ensuring the synchronicity and coordination of the brake device and saving energy consumption.

[0083] The reverse drive assembly 4 includes a first rack 41, a second rack 42, and an intermediate gear 43 disposed between the two. Through mechanical transmission, it ensures precise synchronization of movement and meets the centering requirements.

[0084] In some embodiments, combined with Figure 7 As shown, the brake device also includes a buffer 14, which is disposed on the limiting surface 13.

[0085] In this embodiment, the buffer 14 can specifically be a rubber pad or a spring structure.

[0086] By further providing a buffer 14 on the limiting surface 13, a buffering effect can be provided when the brake head 2 moves to the extreme position, reducing the impact force, protecting the structural integrity of the neck 11 and the brake head 2, avoiding damage caused by violent collisions, reducing the wear of the limiting surface 13 on the brake head 2, reducing operating noise, and further improving the stability and safety of equipment operation.
