Description

TECHNICAL FIELD

[0001] The present application relates to the field of assembling mechanical equipment, in particular to a spring sheet assembling jig. BACKGROUND

[0002] In the related art, a pipe fitting needs to be assembled with a spring sheet. In the assembling process, an operator needs to press the spring sheet at a certain angle and then put it into the pipe to complete the assembly of the pipe fitting and the spring sheet.

[0003] However, in the above-mentioned assembling process, the operator frequently presses the spring sheet for a long time, and the operator's working strength is large, which is easy to hurt the fingers. SUMMARY

[0004] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, the present application provides a spring sheet assembling jig which automatically compresses the spring sheet, reduces the labor intensity of the operator, improves the assembly efficiency and ensures good assembly effect.

[0005] According to the spring sheet assembling jig of the embodiment of the present application, the spring sheet assembling jig comprises a conveying track, a feeding mechanism, an assembling mechanism and a staggered distribution mechanism. The conveying track has a feeding end and a discharging end, and is used for conveying the spring sheet from the feeding end to the discharging end. The feeding mechanism is used for placing the spring sheet on the feeding end of the conveying track. The assembling mechanism is arranged adjacent to the discharging end of the conveying track, and comprises a positioning die, a first driving member and a second driving member. The positioning die has an installation area and a pipe insertion area on opposite sides thereof, and is provided with a positioning hole. One end of a workpiece pipe is adapted to be inserted into the positioning hole from the pipe insertion area. The first driving member and the second driving member are located in the installation area. The first driving member is arranged to push the spring sheet in a first direction, and is used for pushing the spring sheet into the workpiece pipe when moving towards the positioning hole. The second driving member is arranged to push the spring sheet on the first driving member in a second direction to adjust the angle or compress the spring sheet. The staggered distribution mechanism is located at the discharging end of the conveying track, and is used for sending the spring sheet conveyed to the discharging end to the installation area of the positioning die.

[0006] According to the spring sheet assembling jig of the embodiment of the present application, the staggered distribution mechanism pushes the spring sheet to the preset position on the installation area one by one, avoiding the interference of multiple spring sheets with the movement of the first driving member. The first driving member and the second driving member cooperate to constrain the state of the spring sheet entering the positioning hole, avoiding the jamming of the spring sheet with the positioning hole, thereby helping the spring sheet to quickly enter the positioning hole, improving the assembly efficiency and ensuring good assembly effect.

[0007] In some embodiments, the spring sheet assembly jig further comprises a brushing mechanism, which comprises a brush body for brushing the spring sheets on the conveying track. In this way, the brushing mechanism can control the spacing distance between two adjacent spring sheets, and in turn control the installation rhythm of the spring sheets and the workpiece tube, so as to ensure that the insertion rate of the operator matches the rate of the spring sheets entering the workpiece tube, and avoid insufficient supply of spring sheets.

[0008] Further, the brushing mechanism further comprises a brush holder arranged on one side of the conveying track, and a rolling motor mounted on the brush holder, and the brush body is mounted on the rolling motor. In this way, the damping cooperation between the brush body and the spring sheets is facilitated.

[0009] In some embodiments, the first driving member is a first air cylinder, and the axis of the first air cylinder coincides with the axis of the positioning hole. In this way, the size of the pushing force is adjusted by controlling the gas pressure, so as to make the spring sheets enter the workpiece tube smoothly, and avoid violent collision between the spring sheets and the workpiece tube or the spring sheets being stuck in the tube due to insufficient pushing force of the spring sheets.

[0010] In some embodiments, the second driving member is a second air cylinder or a first air pump, and the second driving member is arranged adjacent to the positioning die. In this way, the size of the pushing force is adjusted by controlling the gas pressure, so as to make the spring sheets have limited compression or adjust the angle (position), and avoid interfering with the movement of the first driving member.

[0011] In some embodiments, the second direction is perpendicular to the first direction, and the second driving member is one or more than one;

[0012] When the second driving member is more than one, the second driving members are arranged along the direction of the axis surrounding the positioning hole. In this way, the second driving members can exert the maximum force on the spring sheets.

[0013] In some embodiments, the staggering mechanism is a third air cylinder or a second air pump; when the staggering mechanism is the third air cylinder, the cylinder rod of the third air cylinder pushes the spring sheets to the installation area when moving towards the blanking end; and when the staggering mechanism is the second air pump, the jet of the second air pump sprays the spring sheets from the blanking end to the installation area. In this way, the size of the pushing force is adjusted by controlling the gas pressure, so as to make the spring sheets accurately move to the preset position of the installation area.

[0014] In some embodiments, the assembly mechanism further comprises a bracket, which is located at the installation area, and the staggering mechanism is used to send the spring sheets at the blanking end to the bracket, and the first driving member is located on the side of the bracket away from the positioning die, and the first driving member pushes the spring sheets on the bracket towards the positioning hole.

[0015] In some embodiments, the spring sheet assembly jig further comprises a material placement table, which is arranged adjacent to the assembly mechanism. In this way, the working intensity of the operator is reduced.

[0016] In some embodiments, the spring sheet comprises two sheet strips, upper ends of the two sheet strips are connected to form a connecting end, one of the sheet strips is provided with a plug post, the workpiece tube is provided with a plug hole, and the first driving member is used to push the connecting end and push the connecting end into the workpiece tube, and the plug post is inserted into the plug hole; wherein the positioning die is provided with an avoiding groove on the edge of the positioning hole, and the avoiding groove is used to position the plug hole and avoid the plug post.

[0039] The spring leaf assembling jig 100 according to the embodiment of the present application comprises a conveying track 20, a feeding mechanism 10, an assembling mechanism 30 and a distributing mechanism 40. The spring leaf assembling jig 100 is used for assembling the spring leaf 70 into the workpiece tube 61. The conveying track 20 has a feeding end 21 and a discharging end 22, and is used for conveying the spring leaf 70 from the feeding end 21 to the discharging end 22. The feeding mechanism 10 is used for placing the spring leaf 70 on the feeding end 21 of the conveying track 20. The assembling mechanism 30 is arranged near the discharging end 22 of the conveying track 20, and comprises a positioning die 31, a first driving member 32 and a second driving member 33.

[0040] The opposite sides of the positioning die 31 are an installation area b and a tube insertion area a, and the positioning die 31 is provided with a positioning hole 311 (as shown in Figure 3 The one end of the workpiece tube 61 is adapted to be inserted into the positioning hole 311 from the tube insertion area a. The first driving member 32 and the second driving member 33 are located in the installation area b. The first driving member 32 is arranged to push the spring leaf 70 in a first direction, and is used for pushing the spring leaf 70 into the workpiece tube 61 when moving towards the positioning hole 311. The second driving member 33 is arranged to push the spring leaf 70 on the first driving member 32 in a second direction, so as to adjust the angle of the spring leaf 70 or compress the spring leaf 70. The second direction forms a preset angle with the first direction. The distributing mechanism 40 is located at the discharging end 22 of the conveying track 20, and is used for sending the spring leaf 70 conveyed to the discharging end 22 to the installation area b of the positioning die 31.

[0041] That is to say, the spring leaf assembling jig 100 according to the embodiment of the present application is fed by the feeding mechanism 10, is fed on the conveying track 20, has the spring leaf 70 sent to the installation area b one by one by the distributing mechanism 40, and has the first driving member 32 and the second driving member 33 of the assembling mechanism 30 cooperate to complete the installation of the spring leaf 70 into the workpiece tube 61.

[0042] In some embodiments, the spring leaf 70 is substantially V-shaped. The spring leaf 70 comprises two leaf strips 71, and the two leaf strips 71 are connected at the upper ends to form a connecting end. One of the two leaf strips 71 is provided with an insertion column 72. As shown in Figure 3 The wall of the workpiece tube 61 is provided with an insertion hole 611 matched with the insertion column 72. The spring leaf 70 is inserted into the workpiece tube 61 to install the insertion column 72 into the insertion hole 611, so as to realize the installation of the spring leaf 70 on the workpiece tube 61. The edge of the positioning hole 311 is formed with an avoiding groove 312, and the avoiding groove 312 is used for positioning the insertion hole 611 and avoiding the insertion column 72.

[0043] The feeding mechanism 10 is used for placing the spring leaf 70 on the feeding end 21 of the conveying track 20. The feeding mechanism 10 can be a vibrating disc, or can be a distributing hopper, or can be a suction assembly, and the present embodiment is not limited thereto.

[0044] The conveying track 20 has a feeding end 21 and a discharging end 22. The feeding end 21 is matched with the feeding mechanism 10 to continuously feed the spring sheet 70 from the feeding mechanism 10 into the conveying track 20. The discharging end 22 is matched with the assembling mechanism 30 to continuously feed the spring sheet 70 from the discharging end 22 into the assembling mechanism 30. The conveying track 20 can adopt a belt to convey the spring sheet 70, or a roller to convey the spring sheet 70, or a chain to convey the spring sheet 70, or a threaded rod to convey the spring sheet 70, etc., which is not limited in the embodiment.

[0045] The assembling mechanism 30 is arranged near the discharging end 22 of the conveying track 20, that is, the positioning die 31 is arranged near the discharging end 22 of the conveying track 20. The positioning die 31 is provided with a positioning hole 311, which is a through hole and communicates the installation area b and the pipe inserting area a. As shown in Figure 3 The feeding mechanism 10, the conveying track 20 and the positioning die 31 are arranged in sequence along the X direction, as shown in Figure 4 The installation area b, the positioning die 31 and the pipe inserting area a are arranged along the Z direction. The installation area b is below the positioning die 31, and the pipe inserting area a is above the positioning die 31. The first driving member 32 is arranged along the first direction, which is the Z direction. The first driving member 32 performs linear reciprocating motion, which can be a ball screw mechanism, an electric push rod mechanism or a gear and rack mechanism, etc. The second driving member 33 is arranged along the second direction, which forms a preset included angle with the first direction. The preset included angle can be an obtuse angle, for example, the second direction is in the ZY plane and forms an obtuse angle with the positive direction of the Z axis. The preset included angle can be 90°, for example, the second direction is the Y direction. The second driving member 33 performs linear reciprocating motion, which can be a ball screw mechanism, an electric push rod mechanism or a gear and rack mechanism, etc.

[0046] When the assembling mechanism 30 works, a workpiece pipe 61 is manually inserted into the positioning hole 311 from the end of the pipe inserting area a. Then, the first driving member 32 is on the connecting end of the spring sheet 70 and pushes the connecting end into the workpiece pipe 61, so that the spring sheet 70 is inserted into the end of the installation area b from the positioning hole 311. At the same time, the second driving member 33 compresses the spring sheet 70 or adjusts the angle (position) of the spring sheet 70 relative to the positioning hole 311, so that the two sheet strips 71 can be symmetrical about the axis of the positioning hole 311, ensuring that the position of the spring sheet 70 relative to the positioning hole 311 will not be skewed, avoiding the spring sheet 70 and the positioning hole 311 from being stuck, so that the spring sheet 70 quickly enters the positioning hole 311. Finally, the first driving member 32 continues to push until the inserting column 72 is installed into the inserting hole 611, realizing the installation of the spring sheet 70 in the workpiece pipe 61.

[0047] The misalignment mechanism 40 is located at the unloading end 22 of the conveying track 20, and can be arranged along the Y direction or the Z direction. For example, the misalignment mechanism 40 is an adsorption mechanism arranged along the Z direction, which adsorbs each spring piece 70 from the unloading end 22 to a preset position on the mounting area b of the positioning die 31 in sequence. Alternatively, the misalignment mechanism 40 is a telescopic mechanism arranged along the Y direction, which pushes each spring piece 70 from the unloading end 22 to a preset position on the mounting area b of the positioning die 31 in sequence. The arrangement of the misalignment mechanism 40 can place the spring pieces 70 on the mounting area b one by one, avoiding the interference of multiple spring pieces 70 on the mounting area b with the movement of the first driving member 32.

[0048] In the scheme of the present application, the first driving member 32 and the second driving member 33 cooperate to constrain the state of the spring piece 70 entering the positioning hole 311, avoiding the jamming of the spring piece 70 with the positioning hole 311, thereby realizing the automatic compression of the spring piece 70, reducing the labor intensity of the operator, improving the assembly efficiency, and ensuring good assembly effect. In addition, the misalignment mechanism 40 pushes the spring pieces 70 to the preset positions on the mounting area b one by one, avoiding the interference of multiple spring pieces 70 with the movement of the first driving member 32.

[0049] In some embodiments, the spring piece assembly jig 100 further comprises a brushing mechanism 50, which comprises a brush body 51 for brushing the spring pieces 70 on the conveying track 20. In this way, the brushing mechanism 50 can control the spacing distance between adjacent two spring pieces 70, thereby controlling the installation rhythm of the spring pieces 70 with the workpiece tube 61, ensuring that the insertion rate of the operator matches the rate of the spring pieces 70 entering the workpiece tube 61, and avoiding the insufficient supply of spring pieces 70.

[0050] Specifically, as described in Figure 3 and Figure 5 the conveying track 20 is arranged along the X direction, and the direction in which the conveying track 20 transmits the spring pieces 70 is the positive direction of X. The brushing mechanism 50 comprises a brush body 51, a brush holder 52, and a rolling motor 53. The brush holder 52 is arranged on one side of the conveying track 20, that is, the brush holder 52 is arranged along the Y direction. The rolling motor 53 is installed on the brush holder 52, and the brush body 51 is installed on the rolling motor 53, with the axis of the brush body 51 and the axis of the rolling motor 53 being on the same straight line. The brush body 51 is cylindrical, and the brush body 51 is damp matched with the strip 71 of the spring piece 70 to slow down the movement of the spring piece 70. The brush body 51 is perpendicular to the strip 71, and the force of the brush body 51 on the strip 71 is applied vertically on the strip 71, so that the brush body 51 maximally slows down the movement of the spring piece 70, thereby better playing a delay or slowing down role. The material of the brush body 51 can be rubber or plastic, and the material of the brush body 51 is different from that of the spring piece 70, which is beneficial to the damp matching between them.

[0051] In some embodiments, the brush body 51 and the strip 71 are not perpendicular to each other, but form an acute angle or an obtuse angle.

[0052] In some embodiments, the first driving member 32 is a first cylinder, and an axis of the first cylinder is coincident with an axis of the positioning hole 311.

[0053] It should be noted that the first driving member 32 is a cylinder for pushing the spring strip 70. In this way, on the one hand, the cylinder has a simple structure and is easy to install; on the other hand, the pushing force is adjusted by controlling the gas pressure, so that the spring strip 70 can smoothly enter the workpiece pipe 61, and the spring strip 70 is prevented from colliding with the workpiece pipe 61 violently or from being stuck in the pipe due to insufficient pushing force of the spring strip 70.

[0054] Specifically, the first cylinder is arranged along the axis direction of the positioning hole 311, and the first cylinder has a first cylinder rod, and an end of the first cylinder rod is provided with a matching block (not shown) in a V shape, which can abut against the connecting end of the spring strip 70, so that the first cylinder rod can stably push the spring strip 70.

[0055] In some embodiments, the second driving member 33 is a second cylinder or a first air pump, and the second driving member 33 is arranged close to the positioning die 31.

[0056] It should be noted that the second driving member 33 is a cylinder for pushing the spring strip 70. In this way, on the one hand, the cylinder has a simple structure and is easy to install; on the other hand, the pushing force of the second driving member 33 is smaller than that of the first driving member 32, and the pushing force is adjusted by controlling the gas pressure, so that the spring strip 70 is compressed or the angle (position) of the spring strip 70 is adjusted, and the movement of the first driving member 32 is prevented from being interfered.

[0057] Specifically, the second cylinder is arranged along the second direction and close to the mounting area b of the positioning die 31. The second cylinder has a second cylinder rod, and an end of the second cylinder rod is provided with an abutting block (not shown) for contacting the strip 71 of the spring strip 70, which is beneficial to compressing the spring strip 70 or adjusting the angle of the spring strip 70.

[0058] In some embodiments, the second driving member 33 is an air pump, and the second driving member 33 is a first air pump, and a nozzle of the first air pump is arranged along the second direction, and the spring strip 70 is compressed or the angle of the spring strip 70 is adjusted by high-pressure gas. In this way, the movement of the first driving member 32 is further prevented from being interfered.

[0059] In some embodiments, the second direction is perpendicular to the first direction. In this way, the second driving member 33 can exert the maximum force on the spring strip 70.

Figure 4As shown, the first driving member 32 is arranged along the Z direction, and the second driving member 33 is arranged along the Y direction, and the intersection of the movement directions of the first driving member 32 and the second driving member 33 is located on the axis of the positioning hole 311.

[0061] Further, the second driving member 33 is one or more than one, and when the second driving member 33 is more than one, the second driving member 33 is arranged along the direction around the axis of the positioning hole 311. In this way, the force is applied to the spring sheet 70 from multiple directions, which is further conducive to compressing the spring sheet, and further ensures that the position of the spring sheet 70 relative to the positioning hole 311 will not be skewed.

[0062] Specifically, the second driving member 33 is two, and the second driving member 33 is symmetrically arranged about the axis of the positioning hole 311, one second driving member 33 is arranged corresponding to one strip 71 of the spring sheet 70; and the other second driving member 33 is arranged corresponding to the other strip 71 of the spring sheet 70.

[0063] In some embodiments, the misalignment mechanism 40 is a third cylinder.

[0064] It should be noted that the misalignment mechanism 40 uses a cylinder to push the spring sheet 70. In this way, on the one hand, the cylinder structure is simple and easy to install; on the other hand, the pushing force can be adjusted by controlling the gas pressure, so that the spring sheet 70 can accurately move to the preset position of the installation area b.

[0065] Specifically, as shown in the figure, Figure 4 The third cylinder is arranged along the second direction, that is, the second cylinder and the third cylinder are both arranged along the Y direction, and the second cylinder and the third cylinder are located on the two sides of the positioning die 31 opposite to each other. The third cylinder has a third cylinder rod, and when the third cylinder rod moves towards the blanking end 22, the spring sheet 70 is pushed to the position directly below the positioning hole 311 in the installation area b.

[0066] In some schemes, the misalignment mechanism 40 uses a gas pump, and the misalignment mechanism 40 is a second gas pump, and the nozzle of the second gas pump is arranged along the second direction, and the spring sheet 70 is pushed by high-pressure gas. The jet of the second gas pump sprays the spring sheet 70 from the blanking end 22 to the position directly below the positioning hole 311 in the installation area b.

[0067] In some embodiments, the assembly mechanism 30 further comprises a bracket 34, the bracket 34 is located in the installation area b, the misalignment mechanism 40 is used to send the spring sheet 70 of the blanking end 22 to the bracket 34, the first driving member 32 is located on the side of the bracket 34 away from the positioning die 31, and the first driving member 32 pushes the spring sheet 70 on the bracket 34 towards the positioning hole 311.

[0068] Specifically, as shown in the figure, Figure 4As shown, the bracket 34 comprises a bottom plate and four side plates, the four side plates are sequentially connected to form a rectangular frame, and the bottom plate closes an opening of the rectangular frame. The bracket 34 is located in the mounting area b, and the bracket 34 is arranged opposite to the positioning die 31, and the opening of the bracket 34 faces the positioning die 31. The first driving member 32 is located on one side of the bottom plate, the second driving member 33 is located on one side plate, and the staggering mechanism 40 is located on another side plate, and the two side plates are arranged opposite to each other. The mounting holes are arranged on the bottom plate and the side wall, and the mounting holes are matched with the first driving member 32, the second driving member 33 and the staggering mechanism 40, so that the pushing spring piece 70 can be pushed.

[0069] In some embodiments, the spring piece assembly jig 100 further comprises a material placing table 60, and the material placing table 60 is arranged close to the assembly mechanism 30.

[0070] Specifically, as shown in the figure, Figure 1 The material placing table 60 and the staggering mechanism 40 are located on the same side of the conveying track 20, and are arranged close to the assembly mechanism 30, so that the operator can take the workpiece tube 61 in a short distance, and the working strength of the operator can be reduced.
