Description

Technical Field

[0001] This utility model belongs to the field of mining equipment processing technology, specifically a guide module for a mining circular link chain deburring machine. Background Technology

[0002] As a key load-bearing component of mining machinery, the burrs generated after welding of the chain links in mining applications need to be removed using specialized deburring equipment. Existing deburring machines mostly use fixed guide modules to drive the blades close to the chain links for cutting. For example, the device mentioned in application number CN112658391A for deburring welding of chain links uses a hydraulic cylinder to drive the deburring blade connected to the guide rail to move radially along a fixed track to achieve the switching between work positions. However, under long-term high-load conditions, the following technical defects exist: the guide rail and slider are prone to cumulative plastic deformation under continuous impact loads, causing the radial movement trajectory of the blade to deviate from the initial set work position; traditional modules rely on rigid connections and lack real-time deformation detection and adaptive compensation functions, requiring manual calibration after machine stoppage, reducing operational continuity; the assembly gap between the power rod and the slider widens under high-load conditions, further amplifying the blade end positioning error. These work position deviation problems directly lead to the deburring blade cutting position deviation, resulting in excessive cutting of the chain link substrate or burr residue. While increasing the cross-sectional size of the slide rail can improve rigidity, it cannot eliminate the accumulation of plastic deformation and exacerbates the size and energy consumption of the equipment. Therefore, there is an urgent need to develop a guide mechanism that can suppress deformation deviation and maintain the radial positioning accuracy of the blade. Utility Model Content

A first fixing plate is provided at the front end of both the upper and lower slide rail plates, with a first through hole on the first fixing plate and a second through hole on the second fixing plate. A second fixing plate is connected to the rear end of both the upper and lower slide rail plates. Each of the upper and lower slide rail plates has a slide rail, and an upper slider and a lower slider are respectively installed in the slide rails on the upper and lower slide rail plates. A power rod is provided at the rear side of the upper and lower sliders, with a first power plate at the rear end of the power rod. A first rotating shaft is installed on the lower slider, and a housing is provided outside the first rotating shaft.

The first and second electric actuators drive the axial deflection of the connecting rod, making the rotation center of the blade coincide with the axis of the chain in three dimensions. The electric actuators receive signals from the displacement sensor and complete the adaptive calibration of the blade axis position within a single cutting cycle. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-10 One specific embodiment of this utility model is as follows:

[0028] like Figure 1-10As shown, a guide module for a mining circular link chain deburring machine includes an upper slide rail plate 101 and a lower slide rail plate 102. Each of the upper and lower slide rail plates 101 and 102 is provided with a slide rail 103, which are symmetrically arranged. Each slide rail 103 has an opening of the same length facing the center of the device. An upper slider and a lower slider 105 are respectively installed in the slide rails 103 on the upper and lower slide rail plates 101 and 102. The rear sides of the upper and lower sliders 105 are connected to a power rod 301. The power rod 301 has a symmetrical structure, and external power is synchronously and equally transmitted to the upper and lower sliders 105 through the power rod 301, pushing or pulling the upper and lower sliders 105 to move radially along the slide rails 103. A first rotating shaft 401 is mounted on the sliding block 105. A connecting block 405 is provided at the top of the first rotating shaft 401. A second rotating shaft 402 is provided symmetrically at the top of the connecting block 405 and the first rotating shaft 401. A fourth through hole 410 is provided on the connecting block 405. A connecting rod 501 is mounted on the fourth through hole 410. A first connecting plate 502 is connected to the connecting rod 501 towards the front end of the device. A second connecting plate 503 is vertically mounted at the lower part of the first connecting plate 502. A third connecting plate 504 is mounted symmetrically at the upper part of the first connecting plate 502 and the second connecting plate 503. A de-barbering blade 508 is installed between the second connecting plate 503 and the third connecting plate 504. A second power plate 507 is provided at the bottom of the second connecting plate 503. External power is used to rotate the de-barbering blade 508 through the second power plate 507 to complete the de-barbering process. As can be seen from the above, the core function of the guide module described in this application is to drive the deburring blade 508 to or from the deburring station of the mining circular link chain by the radial movement of the upper and lower sliders 105, and to drive the deburring blade 508 to rotate and perform deburring work at the deburring station. The guide module of the mining circular link chain deburring machine mentioned in this application will be further described below with reference to the embodiments.

[0029] like Figure 1-3 As shown, the upper slide rail 101 and the lower slide rail 102 have the same length and cross-sectional dimensions. The upper slider and the lower slider 105 have an "I"-shaped cross-section, and both have the same cross-sectional dimensions and length. The slide rail 103 is provided with a magnetic strip 104 to reduce the amount of iron filings generated during the deburring process from falling into the slide rail 103.

[0030] like Figure 1-6As shown, the upper slide rail 101 and the lower slide rail 102 are connected to the front end of a first fixing plate 201. The upper and lower parts of the first fixing plate 201 are respectively provided with a plurality of first bolts 202. The first fixing plate 201 is fixed to the upper slide rail 101 and the lower slide rail 102 by the first bolts 202. The first fixing plate 201 is provided with a circular first through hole 205. The first through hole 205 is used for the connecting rod 501 and the front structure of the connecting rod 501 to pass through. The upper slide rail 101 and the lower slide rail 102 are connected to a second fixing plate 203 at their rear ends. The upper and lower parts of the second fixing plate 203 are respectively provided with a plurality of second bolts 204. The second fixing plate 203 is fixed to the upper slide rail 101 and the lower slide rail 102 by the second bolts 204. The upper and lower parts of the second fixing plate 203 are symmetrically provided with second through holes 206. The second through holes 206 are used for the passage of the upper slider and the lower slider 105. The size of the second through hole 206 is the same as the cross-sectional size of the lower slider 105.

[0031] like Figure 1-2 , Figure 4-5 As shown, multiple third bolts 302 are symmetrically positioned at the upper and lower parts of the power rod 301, and the power rod 301 is fixed to the upper slider and the lower slider 105 by the third bolts 302. A first power plate 303 is provided at the rear end of the power rod 301. The center of gravity of the first power plate 303 is at the same height as the center of gravity of the power rod 301. The first power plate 303 is used to connect to external power devices such as hydraulic cylinders or motors, and transmits the thrust and pull forces provided by the external power devices to the upper slider and the lower slider 105 through the power rod 301.

[0032] like Figure 2 , Figure 7-9As shown, the first rotating shaft 401 and the second rotating shaft 402 are respectively mounted on the lower slider 105 and the upper slider with screws. The first rotating shaft 401 and the second rotating shaft 402 have the same length. The first rotating shaft 401 is connected to an external motor and is driven by the motor to rotate clockwise or counterclockwise. The first rotating shaft 401 is provided with a housing 415. A locking gear 403 is provided on the rotating part in the middle of the first rotating shaft 401. A locking buckle 404 is provided on the inner wall of the housing 415. The locking buckle 404 is controlled by the external motor. When the first rotating shaft 401 rotates beyond a preset angle, the locking buckle 404 can automatically lock, preventing the first rotating shaft 401 from continuing to rotate by blocking the locking gear 403. Two clamping plates 411 are symmetrically positioned on the inner walls of both sides of the outer casing 415. Wedges 412 are located inside the clamping plates 411. A third rotating shaft 413 is also provided on the outer casing 415, with two cams 414 on it. When the third rotating shaft 413 rotates, it drives the cams 414 to rotate synchronously. The cams 414 push the wedges 412 into the clamping plates 411, causing the clamping plates 411 to expand and press against the rotating part of the first rotating shaft 401. Friction forces stop the first rotating shaft 401 from rotating. Rotating the first rotating shaft 401 synchronously drives the connecting rod 501 to deflect, causing the front structure of the connecting rod 501 to deflect at a small angle. This aligns the rotating shaft of the deburring blade 508 with the chain body of the mining circular link chain to be deburred. The two clamping plates 411 then lock the first rotating shaft 401 in place, preventing movement of the rotating shaft of the deburring blade 508 during the deburring process. The connecting block 405 has a third through hole 406 symmetrically positioned on both sides of its sidewalls. A first electric actuator 407 and a second electric actuator 408 are located outside the third through hole 406. The first electric actuator 407 and the second electric actuator 408 are conventional linear displacement drive components, and their extension and retraction are driven by an external standard electric control system. A fixing screw 409 is installed on the first electric actuator 407 and the second electric actuator 408. The fixing screw 409 can pass through the threaded hole on the connecting rod 501 and be fixed to the connecting rod 501. The first electric actuator 407 and the second electric actuator 408 are controlled by a motor. The synchronous reverse lifting and lowering of the first electric actuator 407 and the second electric actuator 408 causes the fixing screw 409 to deflect, which in turn causes the connecting rod 501 to deflect, adjusting the angle of the first connecting plate 502 and its front structure so that the rotation axis of the deburring blade 508 is on the same straight line as the mining round link chain body to be deburred. The first rotating shaft 401, the locking buckle 404, the first electric push rod 407, the second electric push rod 408 and the third rotating shaft 413 are all connected to an external standard equipment control unit via wires 416. This unit outputs drive signals according to preset instructions.

[0033] like Figure 1-2 , Figure 4 , Figure 10As shown, the third connecting plate 504 is provided with a fifth bolt 505, which fixes the third connecting plate 504 to the first connecting plate 502. The third connecting plate 504 and the second connecting plate 503 are provided with rotatable mounting grooves 506 for mounting the debarber blade 508. The top and bottom of the debarber blade 508 are provided with multiple fixing holes 509. A telescopic rod matching the blade is provided in the mounting groove 506. The telescopic rod is connected to a spring and a lever. In its natural state, it is in an extended state. It is retracted by a switch. The debarber blade 508 is fixed to the telescopic rod through the fixing holes 509 and rotates to perform the debarbering operation through the mounting groove 506.

[0034] In this embodiment, the device is installed and used through the following steps:

[0035] The upper slide rail plate 101 and the lower slide rail plate 102 are installed and fixed by the first fixing plate 201 and the second fixing plate 203. The upper slider and the lower slider 105 are respectively inserted into the slide rails 103 of the upper slide rail plate 101 and the lower slide rail plate 102. The power rod 301 is installed at the rear end of the upper slider and the lower slider 105. The first rotating shaft 401 and the second rotating shaft 402 are respectively fixed to the lower slider 105 and the upper slider with screws. The connecting rod 501 is inserted into the fourth through hole 410 and the bolt holes on the connecting rod 501 are... Screw in the fixing screw 409 and install the debarber blade 508 in the mounting groove 506 on the second connecting plate 503. Then, install the third connecting plate 504 on the debarber blade 508 in the same way. Fix the third connecting plate 504 to the first connecting plate 502 with the fifth bolt 505. Connect the first power plate 303, the second power plate 507 and the external hydraulic cylinder respectively. Connect the wire 416 to the general power control system of mining machinery. The system sends control commands to each electric drive component in a manner known in the art. The installed guide module is fixed on the deburring station of the mining round link chain. The mining round link chain to be deburred is vertically fixed at an appropriate position on the front end of the first fixing plate 201. The first power plate 303 is pushed forward by the power source, so that the deburring blade 508 is close to the mining round link chain. The first rotating shaft 401, the first electric push rod 407, and the second electric push rod 408 are finely adjusted so that the rotation axis of the deburring blade 508 coincides with the chain axis of the mining round link chain. The first rotating shaft 401 is locked, and the calibration work is completed. Thereafter, the guide module is calibrated periodically using the above steps. This can effectively prevent the deburring station from shifting due to bending deformation of the mechanical structure, reduce damage to the mining round link chain during deburring, and increase the yield rate.
