Description

Technical Field

[0001] This utility model belongs to the technical field of water jacket production equipment, and specifically relates to a fixing device for water jacket production. Background Technology

[0002] Cooling water jackets are widely used in various industrial fields, such as engines, furnaces, and reactors. These devices generate a lot of heat during operation, and if they are not cooled in time, it will lead to equipment damage or reduced efficiency. The main function of cooling water jackets is to provide a reliable cooling method to protect the equipment and maintain its normal operation. During the production and processing of cooling water jackets, corresponding fixing devices are often used to fix the cooling water jackets to facilitate subsequent processing.

[0003] The existing water jacket fixing equipment has the following technical problems:

[0004] It requires manual adjustment and fixation, resulting in low fixing efficiency;

[0005] During the adjustment process, the friction between the water jacket and the arc-shaped plate is relatively large, which can easily lead to wear on the surface of the water jacket.

[0006] After the upper surface of the water jacket is machined, external equipment is needed to rotate the water jacket so that the lower surface of the water jacket is rotated to the top. Utility Model Content

[0007] The purpose of this utility model is to provide a fixing device for water jacket production, which aims to solve the problems existing in the prior art mentioned above.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A fixing device for water jacket production includes a fixing box, a connecting seat, and an arc-shaped clamping plate. A gear is located in the center of the fixing box, with a first rack and a second rack meshing with it on both sides. The first rack and the second rack are parallel. The connecting seat includes a first connecting seat and a second connecting seat that are slidably connected to the fixing box. One side of the first connecting seat is connected to the first rack, and the other side has a first sleeve through which the second rack passes. One side of the second connecting seat is connected to the second rack, and the other side has a second sleeve through which the first rack passes. A first stepper motor is located at the bottom of the fixing box and is connected to the gear transmission. The first rack and the second rack drive the first and second connecting seats on both sides to move synchronously in opposite directions. The arc-shaped clamping plate is located on the top of the first and second connecting seats on both sides, and the arc-shaped clamping plates cooperate to fix the water jacket.

[0010] Furthermore, the top surface of the fixed base is symmetrically provided with two sets of parallel sliding rods on both sides along its length direction. The first connecting base is provided with first sliding sleeves that are slidably connected to the sliding rods on both sides, and the second connecting base is provided with second sliding sleeves that are slidably connected to the sliding rods on both sides. Both the first and second sliding sleeves have openings, and locking bolts are provided at the openings. The locking bolts are used to fix the positions of the first and second sliding sleeves.

[0011] Furthermore, the top surface of the arc-shaped card plate is provided with a U-shaped groove, which is arranged along the top edge of the arc-shaped card plate. Partitions are spaced apart in the U-shaped groove, and a first pulley is provided between the partitions. The rotation direction of the first pulley is the same as the movement direction of the arc-shaped card plate, and the first pulley is used to slide and support the water jacket.

[0012] Furthermore, two sets of rotating mechanisms are slidably connected to the top of the fixed box along its length. One rotating mechanism is connected to the first connecting seat, and the other rotating mechanism is connected to the second connecting seat. The rotating mechanism includes a base and a pulley frame located above the base. The base is slidably connected to the fixed box. Hydraulic cylinders are provided on both sides of the top of the base. The hydraulic rods of the hydraulic cylinders are vertically connected to the bottom of the pulley frame. The pulley frame is provided with two sets of second pulleys at intervals. A second stepper motor is provided on the outside of the pulley frame. The second stepper motor is connected to the pulley drive.

[0013] Compared with the shortcomings and deficiencies of the prior art, the present invention has the following beneficial effects.

[0014] 1. This utility model provides a fixing device for water jacket production. A stepper motor synchronously drives two racks on both sides via gears. The racks on both sides then synchronously move the connecting seats on both sides, causing the arc-shaped clamping plates on both sides to move closer together or further apart, facilitating the fixing of water jackets of different specifications. This utility model uses a stepper motor drive, eliminating the need for manual adjustment and achieving high water jacket fixing efficiency.

[0015] 2. The first connecting seat and the second connecting seat are slidably connected to the slide rods on both sides, and the slide rods guide the movement of the connecting seats on both sides. At the same time, the locking bolts fix the position of the connecting seats on both sides. Combined with the self-locking function of the first step motor, this helps to improve the stability of the fixed water jacket.

[0016] 3. The top of the arc-shaped plate is equipped with a first pulley. When the arc-shaped plate moves and is adjusted, it helps to significantly reduce friction with the surface of the water jacket, thereby reducing wear on the surface of the water jacket.

[0017] 4. The top of the fixed base is equipped with a rotating mechanism. The hydraulic cylinder drives the pulley frame to rise and fall, and the second stepper motor drives the second pulley to rotate, thereby adjusting the position of the water jacket. No external equipment is needed, which improves the convenience of operation. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] Example 1

[0030] Reference Figure 1This embodiment provides a fixing device for water jacket production, including a fixing base body, the fixing base body including a fixing box 10, the fixing box 10 is provided with support columns 11 around the bottom, and the fixing box 10 is provided with symmetrical arc-shaped clamping plates 40 on both sides of the top. The distance between the arc-shaped clamping plates 40 on both sides can be adjusted to fix water jackets 60 of different lengths.

[0031] Reference Figure 2 The top surface of the fixed box 10 is provided with a sliding rod 50 along its length (see reference). Figure 3 Two sets of sliding rods 50 are arranged symmetrically on both sides of the fixed box 10 along its length. The sliding rods 50 are spaced apart from the top surface of the fixed box 10. Two sets of connecting seats 30 are symmetrically slidably connected on both sides of the sliding rods 50, including a first connecting seat 31 and a second connecting seat 32. The first connecting seat 31 is provided with a first sliding sleeve 51 on both sides, and the first sliding sleeves 51 on both sides are slidably sleeved on the sliding rods 50 on both sides. Similarly, the second connecting seat 32 is provided with a second sliding sleeve 52 on both sides, and the second sliding sleeves 52 on both sides are slidably sleeved on the sliding rods 50 on both sides.

[0032] Reference Figure 5 and Figure 6 The first sliding sleeve 51 and the second sliding sleeve 52 are non-closed circular rings. The openings of the first sliding sleeve 51 and the second sliding sleeve 52 are provided with through holes that run vertically through each other. Locking bolts 53 pass through both through holes. Rotating the locking bolts 53 reduces the distance between the openings, thereby clamping the slide rod 50 through the first sliding sleeve 51 and the second sliding sleeve 52 to fix the positions of the first connecting seat 31 and the second connecting seat 32.

[0033] Reference Figure 4 A gear 23 is located in the center of the fixed box 10. The shaft of the gear 23 is vertically connected to the upper and lower inner walls of the fixed box 10. (Refer to...) Figure 2 A first stepper motor 20 is provided on the outer side of the bottom of the fixed box 10. The first stepper motor 20 is connected to the gear 23 for transmission. The first stepper motor 20 is used to drive the gear 23 to rotate. A first rack 21 and a second rack 22 are respectively provided on both sides of the gear 23 to mesh with it. The first rack 21 and the second rack 22 are parallel, and the extension direction of the first rack 21 and the second rack 22 is the same as the length direction of the fixed box 10. A slot 12 is provided in the center of the top surface of the fixed box 10 along its length direction. The lower parts of the first connecting seat 31 and the second connecting seat 32 are respectively inserted into the fixed box 10 along the slot 12. The first connecting seat 31 is connected to the first rack 21, and the first connecting seat 31 is provided with a first sleeve for the second rack 22 to pass through. The first sleeve is slidably engaged with the second rack 22. The second connecting seat 32 is connected to the second rack 22, and the second connecting seat 32 is provided with a second sleeve for the first rack 21 to pass through. The second sleeve is slidably engaged with the first rack 21.

[0034] The vertical sidewalls on both sides of the fixed box 10 are respectively provided with sliding channels 13 that align with the first rack 21 and sliding channels 13 that align with the second rack 22. One sliding channel 13 is used for the first rack 21 to pass through, and the other sliding channel 13 is used for the second rack 22 to pass through.

[0035] Reference Figure 5 The bottom surface of the fixed box 10 is provided with a first slide rail along its length. The bottom of the first connecting seat 31 and the second connecting seat 32 are respectively provided with a first slide groove. The first slide rail is slidably connected to the first slide groove. The first connecting seat 31 and the second connecting seat 32 are slidably supported by the cooperation of the first slide groove and the first slide rail.

[0036] Arc-shaped clamping plates 40 are respectively set on the top of the first connecting seat 31 and the second connecting seat 32, and the arc-shaped clamping plates 40 on both sides cooperate to fix the water jacket 60.

[0037] The working process of this embodiment:

[0038] First, the two curved plates 40 support the water jacket 60.

[0039] Then, the first stepper motor 20 is started, which drives the gear 23 to rotate. The gear 23 synchronously drives the first rack 21 and the second rack 22 on both sides to move in opposite directions. At the same time, the first rack 21 drives the first connecting seat 31 to slide along the slide rod 50, and the second rack 22 drives the second connecting seat 32 to slide along the slide rod 50. The two arc-shaped clamping plates 40 on both sides move synchronously in opposite directions, so that the outer surfaces of the two arc-shaped clamping plates 40 abut against the ends of the water jacket 60.

[0040] Next, tighten the locking bolts 53 on the first sliding sleeve 51 and the second sliding sleeve 52 respectively, so that the first sliding sleeve 51 and the second sliding sleeve 52 press against the sliding rod 50 respectively, so as to fix the position of the arc-shaped clamping plates 40 on both sides, that is, to keep the water jacket 60 fixed.

[0041] It should be noted that the first stepper motor 20 is existing technology, and commercially available products with corresponding specifications and power can be selected according to actual production needs. Furthermore, the first stepper motor 20 has a self-locking function, which helps to fix the position of the arc-shaped clamping plates 40 on both sides.

[0042] Example 2

[0043] Example 2 is a further improvement on Example 1.

[0044] This embodiment provides a fixing device for water jacket production, which can reduce the friction between the arc-shaped clamping plate 40 and the water jacket 60 when the arc-shaped clamping plate 40 moves.

[0045] Reference Figure 5 and Figure 7The top surface of the arc-shaped plate 40 has a U-shaped groove 41 extending along its top edge. Partitions 43 are spaced apart within the U-shaped groove 41, and first pulleys 42 are positioned between adjacent partitions 43. The rotation direction of the first pulleys 42 faces the movement direction of the arc-shaped plate 40, and the top surface of the first pulleys 42 is slightly higher than the top opening of the U-shaped groove 41 at that location. Multiple first pulleys 42 are evenly distributed along the extension path of the U-shaped groove 41.

[0046] The working process of this embodiment follows that of Embodiment 1, and is specifically described as follows:

[0047] The water jacket 60 is placed on the two curved plates 40 on both sides. The first pulley 42 supports the water jacket 60. When the two connecting seats 30 move the two curved plates 40 on both sides in sync, the first pulley 42 rotates, which can greatly reduce the friction between the curved plates 40 and the water jacket 60 and reduce the wear on the surface of the water jacket 60. The curved plates 40 and the two water jackets 60 on both sides are pressed together to fix the water jacket 60.

[0048] Example 3

[0049] Example 3 is a further improvement on Example 1.

[0050] This embodiment provides a fixing device for water jacket production, which has the function of rotating and adjusting the water jacket 60.

[0051] Reference Figure 8 Two sets of rotating mechanisms 70 are slidably installed on the top of the fixed box 10, and the rotating mechanisms 70 are used to drive the water jacket 60 to rotate. Two sets of parallel second slide rails 14 are symmetrically arranged on both sides of the slot opening 12 on the top of the fixed box 10.

[0052] Reference Figure 9 The rotating mechanism 70 includes a base 71 and a pulley frame 72 mounted on the base 71. The base 71 is slidably connected to the second slide rails 14 on both sides. Two sets of hydraulic cylinders 73 are spaced apart between the base 71 and the pulley frame 72. The hydraulic rod ends of the hydraulic cylinders 73 are vertically connected to the bottom of the pulley frame 72. The hydraulic cylinders 73 are used to adjust the height of the pulley frame 72. Two sets of second pulleys 74 are spaced apart on the pulley frame 72. A second stepper motor 76 is provided on one side of the pulley frame 72, and the second stepper motor 76 is drivenly connected to the second pulleys 74.

[0053] The bases 71 of the rotating mechanisms 70 on both sides are connected and fixed to the adjacent connecting seats 30 through connecting plates 75, so that the bases 71 slide with the corresponding connecting seats 30.

[0054] After the base 71 slides along the second slide rail 14 to the designated position, its position can be fixed. The fixing method can be a positioning pin or a set screw. The fixing method is existing technology and will not be described again.

[0055] The working process of this embodiment follows that of Embodiment 1, and is specifically described as follows:

[0056] After the water jacket 60 is fixed and its upper surface is machined, its lower surface needs to be machined.

[0057] First, remove the locking bolt 53 to allow the first sliding sleeve 51 and the second sliding sleeve 52 to slide along the sliding rod 50. Start the first stepper motor 20, which drives the gear 23 to rotate. The gear 23 drives the first rack 21 and the second rack 22 on both sides to move in opposite directions, thereby driving the arc-shaped clamping plates 40 on both sides to move a certain distance in a direction that brings them closer to each other through the connecting seat 30. The rotating mechanisms 70 on both sides move with the corresponding connecting seat 30 through the connecting plate 75.

[0058] Then, the position of the fixed rotating mechanism 70 is fixed, and the PLC controller is used to synchronously drive each hydraulic cylinder 73 to extend, so that the pulley frames 72 on both sides rise synchronously by the same distance. The pulley frames 72 on both sides support and lift the water jacket 60, and the water jacket 60 separates from the arc-shaped clamping plate 40. The second stepper motor 76 is started, and the second stepper motor 76 drives the second pulley 74 to rotate, thereby driving the water jacket 60 to rotate, so that the water jacket 60 rotates at a certain angle.

[0059] Next, control the hydraulic cylinders 73 to retract synchronously, causing the pulley frames 72 on both sides to descend synchronously, so that the water jacket 60 contacts the arc-shaped clamping plate 40, and at the same time the water jacket 60 separates from the second pulley 74. Repeat the working process of Example 1 to fix the water jacket 60 again.

[0060] 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.
