Description

Technical Field

[0001] The present invention relates to the technical field of bolt processing, and in particular to a bolt fixing device for bolt stamping equipment. Background Art

[0002] Bolts, as commonly used mechanical fastening elements, have the characteristics of reliable connection, easy installation, and strong versatility. They are widely used in many industrial fields such as mechanical manufacturing, engineering structures, transportation, energy equipment, etc. In the production process of bolts, stamping is a key process, which usually includes forming the bolt head, embossing the front of the thread, and punching of positioning holes.

[0003] In the actual implementation process, there are still some problems: 1. In traditional bolt stamping operations, due to the limitations of equipment structure and function, it is usually impossible to record or accurately track the stamping action of each bolt in real time. The processing process is mostly a single mechanical pressing process without intelligent identification or marking devices. After the stamping is completed, there is no corresponding processing record archive. As a result, after the operation batch is completed, it is difficult for operators to accurately judge whether there are problems such as fixture position offset, part installation deviation or abnormal stamping accuracy. Once quality defects such as product dimensional deviation and inconsistent indentation occur, not only can they not be discovered in time, but it is also difficult to trace and trace the specific work station, fixture or operation behavior, which seriously restricts the level of product consistency management and process control.

[0004] 2. Currently, most traditional stamping equipment still relies on fixed stroke control. The adjustment of stamping depth usually relies on equipment settings or manual experience, and lacks dynamic perception and real-time feedback mechanisms. In actual use, if the fixture is worn, the bolt model is changed, or there is an operational error, it is very easy for the stamping depth to exceed the reasonable range, resulting in deformation of the bolt head, damage to the thread, and even destruction of the fixture structure. At the same time, the equipment may also cause mechanical jamming or damage to the punch, seriously affecting the stability and service life of the entire machine. Due to the lack of an effective alarm device to assist in judgment, abnormal conditions are often discovered only after the consequences have occurred, posing a large safety hazard and equipment maintenance cost.

[0005] 3. After the operation of traditional stamping equipment is completed, it is often necessary to manually remove the fixed fixture from the equipment or remove the processed bolts from the fixture. The fixture removal and replacement process has a low degree of mechanization and limited automation level. Especially in continuous batch operations, operators need to frequently enter the stamping area to load and unload fixtures and replace products. Not only is the operation cumbersome and labor-intensive, but it is also very easy to cause safety problems such as accidental touch and misoperation. The equipment operation rhythm is limited by the efficiency of manual intervention, and it is impossible to form an efficient and stable rhythmic operation process, which is difficult to meet the dual needs of high efficiency and safe production in current industrial manufacturing.

DETAILED DESCRIPTION

[0022] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0023] Please refer to Figures 1 to 9 As shown, a bolt fixing device of a bolt stamping equipment of the present invention comprises a stamping equipment body 1, an auxiliary stamping mechanism 3 is provided on the top of the stamping equipment body 1, and a stamping detection mechanism 4 is provided on one side of the stamping equipment body 1; The punch detection mechanism 4 includes a marking pen 408, a display whiteboard 404, a stabilizing plate 403, a transmission plate 410, and a spring return lever 409. The inner side of the stabilizing plate 403 is fixedly connected to the display whiteboard 404. The inner side of the transmission plate 410 is fixedly connected to the spring return lever 409. One end of the spring return lever 409 is fixedly connected to the back side of the marking pen 408. The front side of the marking pen 408 is in contact with the front side of the display whiteboard 404. Auxiliary stamping mechanism 3, the auxiliary stamping mechanism 3 includes a guide rail 301, a limiting plate 303, a sliding support 305 and a connecting platform 306. The bottom end of the connecting platform 306 is fixedly connected to the top of the sliding support 305, and the bottom end of the connecting platform 306 is slidably connected to the top of the guide rail 301. The two limiting plates 303 are respectively fixedly connected to the two sides of the inner wall of the guide rail 301.

[0024] Optionally, the stamping detection mechanism 4 also includes a fixing fixture 401, a positioning hole 402, a rack 1 412, a gear 413 and a rack 2 414. The positioning hole 402 is opened at the top of the fixing fixture 401. The inner wall of the positioning hole 402 is fixedly embedded with a limiting tube 417. The inner wall of the limiting tube 417 is fixedly connected to a limiting ring 424. The top of the limiting ring 424 is fixedly connected to a reset spring 419. The top of the reset spring 419 is fixedly connected to a top plate 420. The top plate 420 is slidably connected to the inner wall of the limiting tube 417. In the actual implementation process, after the user inserts the bolt into the positioning hole 402, the bottom end of the bolt abuts against the top plate 420. When the stamping operation starts, the bolt is pressed to push the top plate 420 downward. The top plate 420 completes the limiting and resetting under the action of the reset spring 419. After the bolt stamping is completed, the reset spring 419 will push the top plate 420 back to its original position. During the rebound process of the top plate 420, the bolt will be pushed out of the positioning hole 402, so that the user can easily take out the finished bolt, thereby improving the convenience of operation and production efficiency.

[0025] Optionally, a threaded barrel 423 is fixedly connected to the bottom end of the top plate 420, a trigger rod 421 is threadedly connected to the inner wall of the threaded barrel 423, a push-type trigger alarm 422 is fixedly connected to the inner side of the fixing fixture 401, and the bottom of the trigger rod 421 is placed on the top of the push-type trigger alarm 422. In actual implementation, when the top plate 420 moves downward, driving the threaded barrel 423 and the trigger rod 421 to move, if the bolt is punched too deep, the bottom end of the trigger rod 421 triggers the alarm, creating an audible and visual alarm, notifying the user of an abnormal punching depth, helping to prevent product scrapping and improving work safety. The user can adjust the distance between the trigger rod 421 and the push-type trigger alarm 422 by rotating the trigger rod 421, the top of which is threadedly connected to the threaded barrel 423.

[0026] Optionally, one end of the transmission plate 410 is pivotally connected to the outer wall of the trigger rod 421. A limit slot 416 is defined on the outer side of the fixing fixture 401. The middle portion of the transmission plate 410 extends through the limit slot 416 and is vertically slidably connected to the inner wall of the limit slot 416. In actual implementation, movement of the trigger rod 421 simultaneously drives the transmission plate 410 to slide up and down along the limit slot 416, ensuring the stability and guidance of the transmission path.

[0027] Optionally, stabilizing plate 403 is slidably connected to the outer wall of fixing fixture 401, connecting plate 411 is fixedly connected to the outer side of transmission plate 410, the back of rack 1 412 is fixedly connected to the outer side of connecting plate 411, fixing plate 407 is fixedly connected to the outer wall of fixing fixture 401, and the bottom end of rack 2 414 is slidably connected to the top end of fixing plate 407. In actual implementation, transmission plate 410 drives connecting plate 411 and rack 1 412 to move, and rack 1 412 engages gear 413 to drive rack 2 414, achieving power steering and driving stabilizing plate 403 to move, thereby triggering the marker.

[0028] Optionally, the bottom end of rack 2 414 is fixedly connected to a locking plate 415, the inner side of the locking plate 415 is fixedly connected to an extension plate 406, the bottom end of the stabilizing plate 403 is fixedly connected to the limiting tooth 405, the top end of the extension plate 406 is fixedly connected to a spring return rod 2 418, and the top end of the spring return rod 2 418 is attached to the bottom end of the stabilizing plate 403. In the actual implementation process, when the rack 2 414 moves forward (i.e. during the stamping process), it drives the locking plate 415, the extension plate 406 and the return spring 419 rod 2 to act together, the return spring 419 rod 2 pushes the limit tooth 405 forward, and further pushes the stabilizing plate 403 to achieve the marking or limiting action. At this time, the movement direction of the limit tooth 405 is along the sliding direction of the inclined surface, and the resistance is small, and the pushing can be completed smoothly. However, in the process of resetting (i.e. returning) the rack 2 414, since the other end of the limit tooth 405 is an inclined structure (inclined surface), it forms a sliding resistance with the elastic force direction of the reset direction. Although the return spring 419 rod 2 has a certain thrust , but it is not enough to overcome the reaction force caused by the sliding of the inclined plane. Therefore, during the retreat of the rack 2 414, the limit tooth 405 cannot be actively brought back by the spring, forming a one-way stopping effect similar to the pawl pressing the ratchet and being unable to push back, thereby preventing the automatic return of the stabilizing plate 403. In actual use, the operator needs to manually reset the stabilizing plate 403 to make the limit tooth 405 pass over the inclined limit groove 416 and return to its initial state to ensure the accuracy and continuity of the next cycle of action. This structure can not only prevent the premature reset of the unfinished action, enhance the one-way controllability of the marking action, but also improve the controllability and safety of the operation through manual intervention.

[0029] Optionally, the inner side of rack 1 412 and the top of rack 2 414 are respectively engaged with the outer side of gear 413, the bottom end of the stamping equipment body 1 is fixedly connected to the processing table 2, and the bottom end of the fixing fixture 401 is fixedly connected to the top of the connecting table 306.

[0030] Optionally, the auxiliary stamping mechanism 3 further includes a screw 304, a transmission wheel 308 and a transmission belt 307. The bottom end of the guide rail 301 is fixedly connected to the top of the processing table 2. The screw 304 is rotatably connected between the two limit plates 303, and the sliding support 305 is threadedly connected to the screw 304. In actual implementation, the user can start the servo motor 302 to drive the transmission wheel 308 to rotate the screw 304, so that the sliding support 305 carries the connecting platform 306 and the fixed fixture 401 thereon to move synchronously. This structure is not only conducive to achieving rapid conversion between multiple workstations, but also can automatically move the fixture to the outside of the stamping equipment body 1 after completing a batch of bolt stamping, facilitating manual product removal, inspection or replacement operations, significantly improving the level of automation and operating efficiency.

[0031] Optionally, a transmission belt 307 is sleeved between the two transmission wheels 308 , wherein one of the transmission wheels 308 is fixedly sleeved on one end of the screw rod 304 , and the outer wall of the processing table 2 is fixedly connected to the servo motor 302 .

[0032] Optionally, another transmission wheel 308 is fixedly sleeved on the output end of the servo motor 302 , and the sliding support 305 is slidably connected to the inner wall of the guide rail 301 .

[0033] Working principle: When the user needs to punch a bolt, first place the bolt to be processed into the positioning hole 402 provided on the fixing fixture 401 to achieve preliminary positioning. Then, the user installs the fixing fixture 401 inside the stamping equipment body 1 so that the fixture and the stamping device are aligned. After starting the stamping equipment, its output end will apply force downward to punch the bolt. During the stamping process, the bolt moves downward under the force, and its bottom end is against the top plate 420 provided under the fixture. When the bolt is continuously pressed in, the top plate 420 moves downward synchronously under the action of pressure, and drives the threaded barrel 423 connected thereto to undergo axial displacement. The downward movement of the threaded barrel 423 further drives the trigger rod 421 provided inside to move downward. If the stamping When the depth exceeds the set threshold, that is, the bolt is pressed too deep, the bottom end of the trigger rod 421 will press the push-type trigger alarm 422 set at the bottom of the clamp. At this time, the push-type trigger alarm 422 is activated, and an audible and visual warning signal is issued, which can promptly remind the user that there is a processing abnormality in the equipment, avoiding deformation of the bolt, structural damage or unqualified products due to excessive stamping, thereby significantly improving the safety and stability of stamping. At the same time, the trigger rod 421 will drive the transmission plate 410 to move in the horizontal direction during the movement. The transmission plate 410 is connected to the connecting plate 411. The inner wall of the connecting plate 411 is provided with a rack 1 412, which can drive the gear 413 meshing with it to rotate during the movement. The rotation of the gear 413 further drives the rack 2 414 meshing with it. The movement of the second rack 414 will push the locking plate 415 to move along the set trajectory, and the extension plate 406 provided in the locking plate 415 will drive the spring return rod 2 418 to axially displace during the movement, thereby pushing the limit tooth 405 to be linked, and then pushing the stabilizing plate 403 located on the side to move. A spring return rod 1 409 is also provided on the inner side of the transmission plate 410. When it moves with the transmission plate 410, it will synchronously drive the marking pen 408 provided at its end to mark on the display whiteboard 404. After each bolt is stamped, the marking pen 408 will record the corresponding mark on the whiteboard to form a one-to-one corresponding visual marking track. The user can complete a batch of bolt stamping processes by After that, it is possible to determine whether the marks on the display whiteboard 404 are uniform and neat, thereby judging whether there are any abnormalities or repeatability errors in the fixture during the stamping process. If the mark positions are inconsistent, the state of the fixing fixture 401 can be checked in time, and the bolts with problems can be screened and recycled to ensure product consistency and yield. After the bolt stamping is completed, the reset spring 419 will push the top plate 420 to return to its original position. During the rebound process of the top plate 420, the bolt will be ejected from the positioning hole 402, allowing the user to easily take out the finished bolt, thereby improving the convenience of operation and production efficiency. After the user completes the stamping of the bolt, the drive servo motor 302 arranged on one side of the device can be started. The output end of the servo motor 302 is connected to the first transmission wheel 308.During the rotation process, the first transmission wheel 308 drives the second transmission wheel 308 to rotate synchronously via the transmission belt 307. The second transmission wheel 308 is connected to the screw rod 304, thereby driving the screw rod 304 to rotate. The rotation of the screw rod 304 further drives the sliding support 305 threadedly connected to it to slide along the preset guide rail 301. The sliding support 305 is fixedly connected to the connecting platform 306. The movement of the connecting platform 306 can drive the fixing fixture 401 as a whole away from the stamping equipment body 1, and the workstation is automatically moved out after processing is completed.
