Description

Technical Field

[0001] This application relates to the technical field of shipbuilding, and particularly to a fixing device for small outfitting parts with adjustable angles. Background Art

[0002] Outfitting is one of the shipbuilding processes, which is divided into sectional outfitting, dock (shipbuilding berth) outfitting, and quay outfitting. For the assembly of small iron outfitting parts, most of the existing welding methods first fix them manually, then spot weld, and then use welding fixtures. When manually fixing and spot welding small iron outfitting parts, it is easy to cause occupational health hazards, and manual fixing during the welding process will, to a certain extent, affect the precision control. Summary of the Invention

[0003] The purpose of the embodiments of this application is to provide a fixing device for small outfitting parts with adjustable angles, which can solve the above problems existing in the prior art and adapt to the welding work of small outfitting parts in complex and changeable shipbuilding and installation environments.

[0004] To achieve the above object, this application adopts the following technical solutions:

[0005] On the one hand, a fixing device for small outfitting parts with adjustable angles is provided, including: a fixing fixture, a first adsorption component, and a plurality of support members. The fixing fixture includes a first fixing workpiece and a second fixing workpiece that are vertically and cross-connected. The center of the first fixing workpiece overlaps above the center of the second fixing workpiece. An included angle a is formed between the first fixing workpiece and the second fixing workpiece. Activity holes are correspondingly opened at the center positions of the first fixing workpiece and the second fixing workpiece. The second fixing workpiece can rotate relative to the first fixing workpiece with the activity holes as the fulcrum, thereby adjusting the size of the included angle a. An angle sensor for detecting the size of the included angle a is arranged between the first fixing workpiece and the second fixing workpiece. The bottom end of the first adsorption component passes through the activity hole and is arranged below the activity hole. The bottom end of the first adsorption component is used for adsorbing small outfitting parts. Each of the support members is movably installed at the ends of the first fixing workpiece and the second fixing workpiece and can move up and down relative to the fixing fixture to adjust the height of the bottom end of the first adsorption component. A fixing mechanism electrically connected to the angle sensor is arranged at the bottom of each of the support members, and the fixing mechanism includes a standby state and a working state. The fixing mechanism is configured such that when the angle sensor detects that the included angle a is less than or equal to a preset angle, a control instruction is sent to the fixing mechanism, and the fixing mechanism switches from the standby state to the working state. When the fixing mechanism is in the working state, the bottom of the fixing mechanism relatively expands and abuts against the ground to fix the fixing fixture and the first adsorption component.

[0006] Optionally, when the fixing mechanism is in the standby state, the bottom of the fixing mechanism closes relatively and contracts inside the bottom end of the support member.

[0007] Optionally, a magnetic attraction device electrically connected to the angle sensor is arranged inside the support member, and a metal part that cooperates with the magnetic attraction device for magnetic attraction is arranged at the top end of the fixing mechanism. When the fixing mechanism is in the standby state, the magnetic attraction device is energized to generate a magnetic attraction force to adsorb the metal part, so that the fixing mechanism retracts inside the support member.

[0008] Optionally, an elastic member is arranged between the fixing mechanism and the inner wall of the support member, and the elastic member makes the fixing mechanism always have a tendency to move out of the support member.

[0009] Optionally, it further includes a plurality of extension members and locking members. Each of the extension members is respectively connected to the ends of the first fixing workpiece and the second fixing workpiece and is locked by the locking members.

[0010] Optionally, the preset angle is 45°. When the included angle a is less than or equal to 45°, the fixing mechanism switches from the standby state to the working state.

[0011] Optionally, the first adsorption assembly includes a pull ring, an adsorption rod and a magnetic force seat. The pull ring is installed at the top end of the adsorption rod, the magnetic force seat is installed at the bottom end of the adsorption rod, and the adsorption rod penetrates through the movable hole and can move up and down relative to the fixing tooling.

[0012] Optionally, the movable hole is a threaded hole, and a threaded structure that rotates in cooperation with the threaded hole is arranged on the outer wall surface of the adsorption rod.

[0013] Optionally, the cross section of the magnetic force seat is trapezoidal.

[0014] Optionally, the center of the first fixing workpiece overlaps above the center of the second fixing workpiece, and a handle protrudes above the center of the first fixing workpiece.

[0015] The beneficial effects of the present application are as follows: The first fixing workpiece and the second fixing workpiece serve as the central base of the entire device. Inserting the first adsorption component at the central position of the device can ensure that the first adsorption component remains relatively stable when adsorbing small outfitting parts, avoiding the shaking of small outfitting parts during the welding process, and thus ensuring the welding accuracy of small outfitting parts. The relative position between the first fixing workpiece and the second fixing workpiece can be adjusted, that is, the included angle between the two can become larger or smaller. When facing a narrow installation environment, the first fixing workpiece can be adjusted to move relative to the second fixing workpiece, thereby reducing the included angle and driving the first fixing workpiece and the second fixing workpiece to approach a parallel state. In this state, in order to ensure the stability of the entire device, the size of the included angle is monitored in real time through an angle sensor. When the included angle between the first fixing workpiece and the second fixing workpiece is less than or equal to a preset angle (the preset angle refers to the situation where when the included angle is less than this preset range, each support member cannot effectively ensure the stability of the device), the angle sensor will send relevant control instructions to the fixing mechanism at this time, and then control the bottom of the fixing mechanism to open relatively to expand the support area of the entire device and ensure the stability of the device. Moreover, this stable method belongs to automatic control and does not require manual intervention and adjustment, which will be more convenient and effective in actual application. In addition, the first adsorption component can move up and down relatively, so the height can be adjusted according to the size of the small outfitting part to meet the requirements of the welding height. At the same time, it can avoid the operator bending down for welding, reduce the probability of occupational diseases, and effectively ensure the personal health and safety of the operator.

Specific embodiments

[0023] To make the technical problems solved by this application, the technical solutions adopted, and the achieved technical effects clearer, the following further details the technical solutions of the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of this application.

[0024] In the description of this application, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0025] In this application, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the first feature has a higher horizontal height than the second feature. The first feature being "below", "below", and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the first feature has a lower horizontal height than the second feature.

[0026] Such as Figures 1-5As shown in the figure, this embodiment provides a fixing device for small outfitting parts with adjustable angles, including: a fixing tooling 1, a first adsorption component 2, and a plurality of support members 3. The fixing tooling 1 includes a first fixing workpiece 101 and a second fixing workpiece 102 that are vertically and cross-connected. The center of the first fixing workpiece 101 overlaps above the center of the second fixing workpiece 102. An included angle a is formed between the first fixing workpiece 101 and the second fixing workpiece 102. Activity holes are correspondingly provided at the center positions of the first fixing workpiece 101 and the second fixing workpiece 102. The second fixing workpiece 102 can rotate relative to the first fixing workpiece 101 with the activity holes as the fulcrum, thereby adjusting the size of the included angle a. An angle sensor for detecting the size of the included angle a is provided between the first fixing workpiece 101 and the second fixing workpiece 102. The bottom end of the first adsorption component 2 passes through the activity hole and is arranged below the activity hole. The bottom end of the first adsorption component 2 is used for adsorbing small outfitting parts. Each of the support members 3 is movably installed at the ends of the first fixing workpiece 101 and the second fixing workpiece 102 and can move up and down relative to the fixing tooling 1 to adjust the height of the bottom end of the first adsorption component 2. A fixing mechanism 6 electrically connected to the angle sensor is provided at the bottom of each of the support members 3, and the fixing mechanism 6 includes a standby state and a working state. The fixing mechanism 6 is configured such that when the angle sensor detects that the included angle a is less than or equal to a preset angle, a control instruction is sent to the fixing mechanism 6, and the fixing mechanism 6 switches from the standby state to the working state. When the fixing mechanism 6 is in the working state, the bottom of the fixing mechanism 6 relatively spreads open and abuts against the ground to fix the fixing tooling 1 and the first adsorption component 2.

[0027] Based on the above scheme, the center positions of the first fixed workpiece 101 and the second fixed workpiece 102 included in the fixed tooling 1 overlap, and corresponding movable holes are opened at the center positions of the two. The bottom end of the first adsorption component 2 can pass through the movable hole and extend downward. Here, the first adsorption component 2 can be locked at any position, that is, the height of the first adsorption component 2 can be adjusted according to actual welding requirements, and then the welding height of the small outfitting parts can be adjusted. In the initial state, the first fixed workpiece 101 and the second fixed workpiece 102 are vertically connected, that is, they are connected in a cross manner. When facing a complex shipbuilding environment, the space for placing the fixing tool 1 is limited. At this time, the angle a between the first fixed workpiece 101 and the second fixed workpiece 102 can be adjusted so that the two are relatively close to each other. In this way, the area occupied by the fixing tool 1 will be reduced, which can be suitable for a narrow and long installation environment. Considering that after the angle a becomes smaller, the original support member 3 may not be sufficient to support the entire fixing device, in order to ensure the stability of the device, a fixing mechanism 6 is provided at the bottom of the support member 3, and an angle sensor is provided between the first fixed workpiece 101 and the second fixed workpiece 102. The angle sensor is electrically connected to the fixing mechanism 6. When the angle sensor detects that the angle a is less than or equal to the preset angle, a control signal is sent to the fixing mechanism 6, and the bottom of the fixing mechanism 6 is relatively opened and abutted on the ground. The stability of the fixing device is improved by increasing the contact area. In this way, even if the angle between the first fixed workpiece 101 and the second fixed workpiece 102 is small, stable support can be guaranteed. This solution provides a fixed support for the welding process of small outfitting parts. When faced with a complex ship manufacturing environment, the fixing device can meet the requirements of small outfitting parts for welding conditions, and the welding height can be adjusted quickly at any time. Moreover, since most of the overall structure of the device is detachable, it can be adaptively disassembled and assembled according to the complexity of the installation environment to ensure that the device can be stably fixed in the installation environment, thereby ensuring that the small outfitting parts can be effectively and stably adsorbed, providing a prerequisite for precision in welding work.

[0028] Preferably, when the fixing mechanism 6 is in the standby state, the bottom of the fixing mechanism 6 is relatively closed and retracted inside the bottom end of the support member 3. In order to prevent the fixing mechanism 6 from affecting the support member 3 when not in use, the fixing mechanism 6 is designed to be retracted to the bottom end of the support member 3 when not in use, and to extend from the bottom end of the support member 3 and open the bottom when in operation. Such a design is suitable for situations where the ground installation position is limited. It can be understood that there is not enough installation position on the ground for the fixing mechanism 6 to open. If the fixing mechanism 6 is always in the open state, the support member 3 cannot be installed to the preset position. The installation can be achieved by retracting the fixing mechanism 6. In addition, in the case of an installation environment with abutment against a side wall, the bottom of the fixing mechanism 6 can be abutted against the side wall after opening, which can also play a role in stable abutment support.

[0029] In some embodiments, a magnetic attraction device electrically connected to the angle sensor is disposed inside the support member 3, and a metal part that cooperates with the magnetic attraction device for magnetic attraction is disposed at the top end of the fixing mechanism 6. When the fixing mechanism 6 is in the standby state, the magnetic attraction device is energized to generate a magnetic attraction force to adsorb the metal part, so that the fixing mechanism 6 retracts into the inside of the support member 3. By the cooperation of the magnetic attraction device and the metal part, the fixing mechanism 6 can be intelligently and automatically adsorbed and locked inside the support member 3. The magnetic attraction device is turned on and off by receiving a control signal from the angle sensor. Only when the included angle a meets the judgment condition, the angle sensor will send a control signal to turn off the magnetic attraction device, so that the fixing mechanism 6 can extend and open the bottom.

[0030] In order to enable the fixing mechanism 6 to quickly and effectively extend from the inside of the support member 3, an elastic member is disposed between the fixing mechanism 6 and the inner wall of the support member 3, and the elastic member makes the fixing mechanism 6 always have a tendency to move out of the support member 3. When the fixing mechanism 6 retracts into the inside of the support member 3, since the magnetic attraction force between the magnetic attraction device and the metal part is greater than the elastic force of the elastic member, the elastic member is in a compressed state. When the magnetic attraction force disappears, the fixing mechanism 6 can quickly pop out of the inside of the support member 3 under the action of the elastic force of the elastic member. When the bottom of the fixing mechanism 6 disengages from the support member 3, the bottom of the fixing mechanism 6 naturally opens and abuts for support.

[0031] Optionally, it further includes a plurality of extension members 4 and locking members 7. Each of the extension members 4 is respectively connected to the ends of the first fixing workpiece 101 and the second fixing workpiece 102 and is locked by the locking member 7. During the welding process, considering that a certain dimension of a small outfitting part may be relatively large, such as a long length, the original fixing tooling 1 cannot effectively and stably adsorb the small outfitting part. In this case, the fixing tooling 1 is extended. Specifically, extension members 4 are added to the ends of the first fixing workpiece 101 and the second fixing workpiece 102, and the extension members 4 are locked by the locking members 7 to ensure that the fixing tooling 1 and the extension members 4 are kept horizontally aligned after connection. After adding the extension members 4, a support member 3 is inserted at the end of the extension members 4, so that the support member 3 can move up and down relative to the extension members 4. The purpose of moving up and down is to adjust the height of the extension members 4, and further adjust the height of the adsorbed small outfitting part to facilitate welding.

[0032] In the case where the extension member 4 is not provided, the preset angle is 45°. When the included angle a is less than or equal to 45°, the fixing mechanism 6 switches from the standby state to the working state. When the extension member 4 is not added, the distance between the first fixing workpiece 101 and the second fixing workpiece 102 is relatively small. In this case, setting the preset angle to 45° can ensure that the bottom of the fixing mechanism 6 will not collide with the bottom of the adjacent fixing mechanism 6 after opening, and the reason for setting this angle is that when it is less than 45°, the first fixing workpiece 101 and the second fixing workpiece 102 cannot always maintain a stable state through the bottom support of the support member 3. For welding, the accuracy cannot be guaranteed. Therefore, when the included angle a is less than or equal to 45°, it is necessary to open the fixing mechanism 6 to ensure the stability of the entire device.

[0033] In the case where the extension member 4 is added, the preset angle can be 40° or 35°. Taking 35° as an example, since the extension member 4 is added to the ends of both the first fixing workpiece 101 and the second fixing workpiece 102, the gap between the extension members 4 will increase. That is to say, the gap at the end of the extension member 4 will be larger than the gap between the first fixing workpiece 101 and the second fixing workpiece 102. Therefore, when the bottom of the adjacent fixing mechanism 6 opens, there will be a larger tolerance space, and 35° is the set limit angle. It can be understood that when the included angle a is equal to 35°, the entire device with the extension member 4 added can still maintain a relatively stable state.

[0034] In addition, in the above solution, the support member 3 is mainly a strip-shaped structure, specifically a cylindrical shape, and is located at the four end corners of the entire fixing device. When the fixing mechanism 6 is not opened, it can directly abut against the ground to support the entire device. When facing an uneven ground, the support member 3 can be clamped in the gap for support due to its small structure design. It can be understood that the support member 3 is inserted between two devices to achieve the purpose of stably supporting the fixing device. On the other hand, also because of the strip-shaped design of the support member 3, it can better adapt to complex installation environments and play a role in stabilizing small outfitting parts. In addition, each support member 3 is independent of each other and does not affect each other. Therefore, when facing an installation environment with inconsistent heights, the height of each support member 3 can be independently adjusted to make the first fixing workpiece 101 and the second fixing workpiece 102 maintain a horizontal state as a whole, greatly improving the application range of the fixing device.

[0035] Optionally, the first adsorption component 2 includes a pull ring 201, an adsorption rod 202, and a magnetic base 203. The pull ring 201 is installed at the top end of the adsorption rod 202, and the magnetic base 203 is installed at the bottom end of the adsorption rod 202. The adsorption rod 202 is inserted through the movable hole and can move up and down relative to the fixed tooling 1. Setting a pull ring 201 structure at the top end of the adsorption rod 202 can facilitate the adjustment operation of the entire first adsorption component 2. By inserting the hand into the pull ring 201 to drive the adsorption rod 202 and the magnetic base 203 to move up and down, the magnetic base 203 can effectively adsorb small outfitting parts. The adsorption rod 202 defines the up and down movement stroke of the small outfitting parts. At the same time, in order to prevent the movement stroke from exceeding the preset range, the pull ring 201 and the magnetic base 203 can be used as the up and down limit parts of the adsorption rod 202 to effectively prevent the small outfitting parts from being displaced too much and detaching.

[0036] To facilitate the assembly between the first adsorption component 2 and the fixed tooling 1, the adsorption rod 202 and the magnetic base 203 are designed with a detachable structure. When the first adsorption component 2 needs to be assembled onto the fixed tooling 1, first disassemble the magnetic base 203. After the adsorption rod 202 passes through the movable hole and extends out, then assemble the magnetic base 203 to the bottom end of the adsorption rod 202. The detachable structure here can be a snap connection method or can be locked by fasteners such as screws or bolts, and different detachable designs can be arbitrarily selected according to the actual situation.

[0037] Preferably, the first adsorption assembly 2 further includes a trigger switch and a circuit assembly. The circuit assembly is installed inside the adsorption rod 202 and connected to the magnetic base 203. When the circuit assembly is turned on, the magnetic base 203 generates a magnetic suction force that can be used to adsorb small outfitting parts. The trigger switch is arranged at the upper part of the adsorption rod 202 and electrically connected to the circuit assembly, and is used to control the conduction or disconnection of the circuit assembly. The setting of the trigger switch and the circuit assembly can improve the convenience and flexibility of adsorbing small outfitting parts. By controlling the on and off of the circuit assembly, the presence or absence of the magnetic suction force of the magnetic base 203 can be controlled. When the circuit assembly is turned on, the magnetic base 203 generates a magnetic force to adsorb small outfitting parts. Here, adsorption means that when the circuit assembly is turned on, the magnetic suction force generated by the magnetic base 203 can effectively and stably adsorb small outfitting parts without detachment or deviation, ensuring that the small outfitting parts can be accurately welded at the predetermined welding position. After the small outfitting parts are welded, if the small outfitting parts need to be put down, only need to control the circuit assembly to disconnect the connection, the magnetic force of the magnetic base 203 disappears, and the small outfitting parts can be taken off. By adopting this adsorption and putting-down method, the situation of manually pulling out small outfitting parts is avoided. Because sometimes in the case of a large adsorption force, the operator needs to use a lot of force to take off the small outfitting parts, which has a negative impact on work efficiency and manpower. However, using the circuit assembly to control the generation of magnetic suction force can effectively solve the above problems, effectively saving manpower and material resources and improving work efficiency. This method can also be to energize and adsorb through the circuit assembly after the positions of the small outfitting parts and the magnetic base 203 are completely corresponding, ensuring that the magnetic base 203 accurately adsorbs the small outfitting parts at the accurate position. In addition, the touch switch is set to control the state of the circuit assembly for convenient control.

[0038] To ensure the safety when using the fixing device, an insulating layer is coated on the outer wall of the adsorption rod 202. The circuit assembly is arranged inside the adsorption rod 202, and there may still be a risk of electric leakage when it is energized. To avoid accidental safety accidents, an insulating layer is wrapped on the outer wall of the adsorption rod 202 to isolate the current and prevent electric shock. In addition, an insulating layer can also be wrapped on the side of the magnetic base 203, as long as the adsorption surface between the magnetic base 203 and the small outfitting parts is not affected.

[0039] In some embodiments, the movable hole is a threaded hole, and a threaded structure that is rotationally matched with the threaded hole is arranged on the outer wall surface of the adsorption rod 202. The adsorption rod 202 adjusts its height by means of threaded connection, which is simple and effective. The height of the magnetic base 203 is adjusted by driving the adsorption rod 202 to rotate through the pull ring 201, and then the welding height of the adsorbed small outfitting parts is adjusted.

[0040] In order to improve the stability of small outfitting parts during the welding process, the magnetic base 203 is designed in a flared structure. Specifically, the cross-section of the magnetic base 203 is trapezoidal. It can be understood that the upper top surface of the magnetic base 203 is connected to the adsorption rod 202, and the lower bottom surface adsorbs the small outfitting part. Moreover, the area of the lower bottom surface is larger than that of the upper top surface, which ensures that the adsorption area between the magnetic base 203 and the small outfitting part is large enough, effectively stabilizing the adsorption of the small outfitting part, overcoming the defect of single-point adsorption, effectively fixing the height of the small outfitting part, avoiding stress displacement during the welding process, and further ensuring that the suspended small outfitting part does not shake during operations such as welding, thus guaranteeing the welding accuracy.

[0041] Furthermore, to ensure the stable and accurate welding position of the suspended small outfitting part, a number of second adsorption components are also included. Each of the second adsorption components is slidably installed on the extension part 4, and each of the second adsorption components can move relative to the first adsorption component 2, and then abuts against the side surface of the small outfitting part to stabilize the small outfitting part. A second adsorption component is slidably provided on each extension part 4 and can move towards the middle first adsorption component 2. After the first adsorption component 2 adsorbs the small outfitting part, if the welding position of the small outfitting part is offset, it can be adjusted by sliding the second adsorption component. Specifically, by the second adsorption component in a certain direction to push against the small outfitting part to cause a horizontal displacement, and then adjusted to the accurate welding position. Since there are corresponding second adsorption components in all directions, it means that the adjustment of the small outfitting part is all-round, ensuring the accurate welding position of the small outfitting part.

[0042] In the solution including the second adsorption component, in addition to the way of pushing against the small outfitting part to adjust the welding position, the welding position of the small outfitting part can also be adjusted by adsorption, specifically as follows: The second adsorption component includes a horizontally arranged auxiliary adsorption rod and a magnet provided at one end of the auxiliary adsorption rod. The small outfitting part is adjusted by the magnetic suction force generated by the magnet on the small outfitting part. The magnet can be non-contact with the small outfitting part and only act on the small outfitting part through the magnetic suction force in the air, causing a small displacement to achieve the purpose of fine adjustment, and this will not affect the position to be welded on the small outfitting part.

[0043] Optionally, the center of the first fixing workpiece 101 is superposed above the center of the second fixing workpiece 102, and a handle 5 is convexly provided above the center of the first fixing workpiece 101. By setting the handle 5 for lifting, when it is necessary to move the fixing device, it can be directly lifted by the handle 5 and moved to the position where it needs to be installed, or it can be moved in cooperation with the handle 5 through a mechanical structure.

[0044] Furthermore, two mounting holes are provided at the ends of the first fixing workpiece 101 and the second fixing workpiece 102. A plurality of locking holes 401 adapted to the mounting holes are formed in the extension member 4, and the distance between two adjacent locking holes 401 is equal to the distance between the two mounting holes. At least two mounting holes are provided at both ends of the two fixing workpieces. The locking member 7 passes through the mounting holes and cooperates with the locking holes 401 on the extension member 4 to lock and fix the extension member 4 to the fixing workpiece. Providing at least two mounting holes and locking holes 401 can ensure the stability of the connection. The locking member 7 can specifically be a screw or a bolt.

[0045] To improve the structural strength of the fixing tooling 1, the first fixing workpiece 101 and the second fixing workpiece 102 are designed as angle steel structures, and stiffeners can also be added thereto to prevent structural fracture when adsorbing small outfitting parts in suspension, ensuring the reliability and safety of the device during use.

[0046] In summary, by using the fixing device described in the present application, it can be adapted to be installed in any complex shipbuilding environment, can stably and effectively adsorb small outfitting parts, and then complete the stable and accurate welding of small outfitting parts, replacing the traditional manual fixing of small outfitting parts, ensuring the operation safety of operators, saving more manpower and material resources, and greatly improving the welding work efficiency at the same time.
