Description

Technical Field

[0001] The utility model relates to the technical field of screw fixing equipment, in particular to a movable barrel screw fixing equipment. Background Art

[0002] In the extrusion compression molding system, the barrel and the screw are important parts of the extruder. The barrel and the screw work together, the barrel contains the screw, and the screw rotates in the barrel. When the screw rotates and pushes the plastic forward in the barrel, the heat from the outside of the barrel is transferred to the plastic in the barrel. In addition, the volume of the screw thread gradually decreases, so that the plastic in the thread groove is subjected to multiple forces such as extrusion, flipping and shearing, and then is evenly mixed and plasticized. The normal cooperation between the barrel and the screw ensures the continuous extrusion of the extruder. When the screw is inspected after production is completed or maintained during use, it is usually necessary to try to use the corresponding fixing equipment to fix it first, so as to facilitate the subsequent work.

[0003] When the screw is inspected or maintained, a simple rack support is usually used to fix the two ends of the screw to achieve its fixed installation. However, this simple fixing method is difficult to play an efficient fixing role when facing the fixing work of screws of different lengths and different diameters. At the same time, the bracket is usually difficult to move, so that the screw can only be inspected or maintained at a fixed position, and the equipment cannot rotate the screw to any angle as required during operation, which will bring many inconveniences to the inspection or maintenance work. Therefore, a movable barrel screw fixing device is proposed to address the above problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a movable barrel screw fixing device, in which the distance between the fixed rotatable clamp responsible for clamping and fixing and the movable rotatable clamp can be freely adjusted within a certain range, so that screws of different lengths can be fixed, and at the same time, the rotation driving structure can drive the fixed rotatable clamp and the movable rotatable clamp to drive the clamped screw to rotate to any angle by working, and in addition, the driving base can drive the mobile trolley equipped with the clamp to move back and forth to adjust the position of the screw, thereby solving the technical problem in the prior art that the screw fixing device is difficult to meet multiple work requirements at the same time during inspection and maintenance, thereby causing inconvenience to the workers' operation.

[0005] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0006] A movable barrel screw fixing device includes a driving base, on which a moving trolley is provided, which can drive the moving trolley to move, a fixed clamping end, which is arranged at the front end of the moving trolley, and a movable clamping end, which is arranged at the rear end of the moving trolley, wherein the fixed clamping end includes a support plate and a rotation driving structure, a fixed rotatable clamp is installed on the support plate, and the rotation driving structure is used to drive the fixed rotatable clamp to rotate, and in addition, the movable clamping end includes a support frame, a slide rail is installed on the support frame, and a movable rotatable clamp is slidably arranged between the slide rails.

[0007] Through the above-mentioned structural form, the fixed rotatable clamp and the movable rotatable clamp work in combination to achieve clamping and fixing of the two ends of the screw rod, and because the movable rotatable clamp can slide back and forth, the distance between the two clamps can be freely adjusted within a certain range, so that screw rods of different lengths can be fixed; at the same time, the rotation driving structure can drive the fixed rotatable clamp to rotate through work, and because the fixed rotatable clamp, the movable rotatable clamp and the screw rod can be regarded as a whole due to the clamping effect, the rotation driving structure can drive the clamped screw rod to rotate to any angle, so that the workers can start work; in addition, the driving base can drive the mobile trolley equipped with the clamp to move back and forth, thereby realizing the adjustment of the position of the screw rod.

[0008] In a possible implementation, the fixed rotatable clamp includes a clamp housing and a rotating shaft, and the two are rotatably connected via a connecting bearing.

[0009] The above-mentioned structural form provides the necessary structural foundation for fixing the rotatability of the rotatable clamp.

[0010] In a possible implementation, the front end of the rotating shaft is fixedly connected to an end plate, the end plate is fixedly connected to a fixing clamping plate, and the fixing clamping plate is bolted to a separating clamping plate.

[0011] Through the above-mentioned structural form, the combined action of the fixed clamping plate and the separating clamping plate provides a clamping force on the end of the screw rod, and the structural form in which the two are separated from each other also enables the two to clamp and fix screw rods of different diameters when working in combination.

[0012] In a possible implementation, a filling clip is detachably connected to the inner wall of the fixed clamp plate and the separation clamp plate, and the filling clip is made of hard rubber and has a surface processed with uneven texture.

[0013] Through the above-mentioned structural form, the filling clips can be used to increase the friction between the fixed clamps, the separation clamps and the screws, thereby improving the fixing effect. At the same time, the filling effect of the filling clips can also be utilized so that the central axes of screws of different diameters can coincide with the central axis of the rotating shaft as much as possible, thereby minimizing the eccentric rotation of the screws.

[0014] In a possible implementation, the structure and size of the movable rotatable clamp are completely consistent with those of the fixed rotatable clamp. In particular, a clamping slider is fixedly provided on both sides of the movable rotatable clamp, and the clamping slider is slidably provided in the groove of the slide rail.

[0015] The above-mentioned structural form provides the necessary structural foundation for the movable rotatable clamp to slide along the slide rail.

[0016] In a possible implementation, the cross-section of the clamping slider is a rounded rectangle, and a bolt is fixedly connected to the outer side of the clamping slider, and a nut matching the bolt is provided.

[0017] Through the above-mentioned structural form, the locking slider can be prevented from rotating in the slide rail, ensuring that the movable rotatable clamp can only slide but not rotate. In addition, when the position adjustment of the movable rotatable clamp is completed, the position of the movable rotatable clamp can be fixed by tightening the nut through the friction between the nut and the slide rail.

[0018] In a possible implementation, the rotary drive structure includes a drive motor, whose output shaft is fixedly connected to a driving wheel, a driven wheel fixedly connected to the rear end of the rotary shaft, and a transmission belt sleeved outside the driving wheel and the driven wheel.

[0019] Through the above-mentioned structural form, the driving motor can drive the active wheel to rotate, and under the transmission action of the transmission belt, drive the driven wheel to rotate, so that the rotating shaft of the fixed rotatable clamp rotates, and then drives the screw to rotate to a specified angle, which is convenient for detection and maintenance work.

[0020] In one possible implementation, the driving base includes a guide rail in which the moving trolley moves, a screw motor whose output shaft is fixedly connected to a transmission screw, and a driving slide which is fixedly arranged at the bottom end of the moving trolley and is threadedly connected to the transmission screw.

[0021] Through the above-mentioned structural form, the screw motor drives the transmission screw to rotate, and then drives the driving slide connected to it threadedly to move forward and backward, so as to drive the moving trolley to drive the screw to move forward and backward to adjust the position.

[0022] In summary, the utility model includes the following beneficial technical effects:

[0023] The fixed rotatable clamp and the movable rotatable clamp work together to clamp and fix the two ends of the screw rod. Since the movable rotatable clamp can slide back and forth, the distance between the two clamps can be freely adjusted within a certain range, so that screw rods of different lengths can be fixed.

[0024] At the same time, the rotation driving structure can drive the fixed rotatable clamp to rotate through work. Since the fixed rotatable clamp, the movable rotatable clamp and the screw rod can be regarded as a whole due to the clamping effect, the rotation driving structure can drive the clamped screw rod to rotate to any angle, so that the workers can work together;

[0025] In addition, the driving base can drive the mobile carriage on which the clamp is installed to move forward and backward, thereby being able to adjust the position of the screw. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0034] like Figure 1 - Figure 2As shown, a movable barrel screw fixing device provided in this embodiment includes a driving base 1, on which a moving trolley 2 is provided, which can drive the moving trolley 2 to move, a fixed clamping end 3, which is arranged at the front end of the moving trolley 2, and a movable clamping end 4, which is arranged at the rear end of the moving trolley 2. The driving base 1 can drive the moving trolley 2 equipped with a clamp to move forward and backward, thereby realizing the adjustment of the position of the screw, and the combined work of the movable clamping end 4 can clamp and fix the screw, and the driving base 1 can drive the moving trolley 2 equipped with the clamp to move forward and backward, thereby realizing the adjustment of the position of the screw.

[0035] like Figure 3 , Figure 5 As shown, the fixed clamping end 3 includes a support plate 31 and a rotating drive structure 33, and a fixed rotatable clamp 32 is installed on the support plate 31. In addition, the movable clamping end 4 includes a support frame 41, and a slide rail 42 is installed on the support frame 41. A movable rotatable clamp 43 is slidably arranged between the slide rails 42. Through the above-mentioned structural form, the fixed rotatable clamp 32 and the movable rotatable clamp 43 work in combination to achieve clamping and fixing of the two ends of the screw, and because the movable rotatable clamp 43 can slide back and forth, the distance between the two clamps can be freely adjusted within a certain range, so that screws of different lengths can be fixed.

[0036] The rotating driving structure 33 is used to drive the fixed rotatable clamp 32 to rotate. At the same time, the rotating driving structure 33 can drive the fixed rotatable clamp 32 to rotate through work. Due to the clamping effect, the fixed rotatable clamp 32, the movable rotatable clamp 43 and the screw can be regarded as a whole. Therefore, the rotating driving structure 33 can drive the clamped screw to rotate to any angle, so that the workers can start work.

[0037] like Figure 4 As shown, the fixed rotatable clamp 32 includes a clamp housing 321 and a rotating shaft 322, and the above two are rotatably connected via a connecting bearing 323. The front end of the rotating shaft 322 is fixedly connected to an end plate 324, and the end plate 324 is fixedly connected to a fixed clamp 325, and the fixed clamp 325 is bolted to a separation clamp 326. Through the above structural form, the combined action of the fixed clamp 325 and the separation clamp 326 provides a clamping force on the end of the screw rod, and the structural form in which the two are separated from each other also enables the two to have a clamping and fixing effect on screws of different diameters when working in combination.

[0038] Among them, the inner walls of the fixed clamp 325 and the separation clamp 326 are detachably connected with a filling clip 327, and the filling clip 327 is made of hard rubber and has an uneven surface. Through the above-mentioned structural form, the filling clip 327 can be used to increase the friction between the fixed clamp 325, the separation clamp 326 and the screw, thereby improving the fixing effect. At the same time, the filling effect of the filling clip 327 can also be utilized, so that the central axis of screws of different diameters can coincide with the central axis of the rotating shaft 322 as much as possible, thereby minimizing the eccentric rotation of the screw.

[0039] like Figure 4 - Figure 5 As shown, the structure and size of the movable rotatable clamp 43 are exactly the same as those of the fixed rotatable clamp 32. In particular, a clamping slider 44 is fixedly provided on both sides of the movable rotatable clamp 43, and the clamping slider 44 is slidably set in the groove of the slide rail 42. Through the above-mentioned structural form, the necessary structural foundation is provided for the movable rotatable clamp 43 to slide along the slide rail 42.

[0040] Among them, the cross-section of the clamping slider 44 is a rounded rectangle, and the outer side of the clamping slider 44 is fixedly connected with a bolt, and is equipped with a nut matching the bolt. Through the above-mentioned structural form, the clamping slider 44 can be prevented from rotating in the slide rail 42, ensuring that the movable rotatable clamp 43 can only slide but not rotate. In addition, when the position adjustment of the movable rotatable clamp 43 is completed, the position of the movable rotatable clamp 43 can be fixed by tightening the nut, through the friction between the nut and the slide rail 42.

[0041] like Figure 3 As shown, the rotation drive structure 33 includes a driving motor 331, whose output shaft is fixedly connected to a driving wheel 333, a driven wheel 332, which is fixedly connected to the rear end of the rotating shaft 322, and a transmission belt 334, which is sleeved outside the driving wheel 333 and the driven wheel 332. Through the above-mentioned structural form, the driving motor 331 can drive the driving wheel 333 to rotate, and under the transmission action of the transmission belt 334, drive the driven wheel 332 to rotate, so that the rotating shaft 322 of the fixed rotatable clamp 32 rotates, and then drives the screw to rotate to a specified angle, which is convenient for detection and maintenance work.

[0042] like Figure 1 As shown, the driving base 1 includes a guide rail 11, in which the moving trolley 2 moves, a screw motor 12, whose output shaft is fixedly connected to a transmission screw 13, and a driving slide 14, which is fixedly arranged at the bottom end of the moving trolley 2 and is threadedly connected to the transmission screw 13. Through the above-mentioned structural form, the screw motor 12 drives the transmission screw 13 to rotate, and then drives the driving slide 14 threadedly connected thereto to move forward and backward, thereby driving the moving trolley 2 to drive the screw to move forward and backward to adjust the position.

[0043] The use principle and use process of this utility model:

[0044] The fixed rotatable clamp 32 and the movable rotatable clamp 43 work in combination to clamp and fix the two ends of the screw rod, and since the movable rotatable clamp 43 can slide back and forth along the slide rail 42, the distance between the two clamps can be freely adjusted within a certain range, so that screw rods of different lengths can be fixed; in addition, the fixed rotatable clamp 32 and the movable rotatable clamp 43 have the same structure, and both provide clamping force on the ends of the screw rod by the combination of the fixed clamp 325 and the separation clamp 326, and the structural form of the two separated from each other also enables the two to have the function of clamping and fixing screw rods of different diameters when working in combination.

[0045] At the same time, the rotating driving structure 33 can drive the fixed rotatable clamp 32 to rotate through work. Due to the clamping effect, the fixed rotatable clamp 32, the movable rotatable clamp 43 and the screw can be regarded as a whole. Therefore, the rotating driving structure 33 can drive the clamped screw to rotate to any angle, so that the workers can start working.

[0046] In addition, the driving base 1 can drive the moving trolley 2 on which the clamp is installed to move forward and backward, thereby being able to adjust the position of the screw.

[0047] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
