Description

Technical Field

[0001] The invention belongs to the field of hardware testing, and relates to a hammer performance testing device, in particular to a multifunctional hammer bending strength testing device. Background Art

[0002] As a representative product of hardware tools, hammers have been widely used in life or related work. With the increasing sales of hammers in global trade, countries are paying more and more attention to the safety of such products. The hammer adopts a simple structure, consisting of a hammer head and a hammer handle, and is a tool for people to use to hit objects to move or deform them. The weight of the hammer should be adapted to the workpiece, material and function. It is unsafe to be too heavy or too light. Cases of injuries caused by quality problems also occur from time to time. Before leaving the factory, the hammer needs to be subjected to basic safety performance tests to verify whether the hammer head or hammer handle is deformed or cracked after being struck, whether the hammer handle and hammer head are loose, and whether the hammer handle is bent or broken under stress during high-intensity use.

[0003] The traditional method of testing the bending resistance of a hammer handle is to use a bending resistance test device to fix the hammer head at one end of the hammer with a block, and the hammer handle at the other end is suspended in the air and directly pressure tested using a lifting structure. However, the existing testing equipment cannot limit the position of the hammer and requires manual auxiliary fixation. During the test, the force on the hammer is prone to offset, which affects the accuracy of the test. It is not only difficult to operate, but also costly and poses a safety hazard during work. In addition, the existing testing equipment can only test the bending strength of the connection between the hammer handle and the hammer head or the bending strength of the hammer handle itself alone. The equipment investment is large, the operation is cumbersome, and the test efficiency is low.

[0004] In addition, the existing testing equipment has a fixed testing method and can only test hammers of certain sizes. During the test, the extrusion force point of the hydraulic rod on the hammer handle cannot be flexibly adjusted according to needs. The measurement method is relatively simple and has a small scope of application. Summary of the invention

The box 200 is installed on the top of the support base 100, and the test bench 300, the tooling seat 400 and the hammer handle tightening mechanism 500 are hidden and installed in the box 200.

[0065] Specifically, the main scheme of the multifunctional hammer bending strength testing device is: at least one test bench 300 is used, which is installed side by side at the top position of the left end of the support base 100, and the tooling seats 400 arranged vertically are detachably installed in the cylindrical grooves 321 thereon for installing the tooling seats 400.

[0066] There is at least one tooling seat 400, which is cylindrical in shape. The number of tooling seats 400 is the same as that of the test bench 300, and they are assembled in groups. In order to be applicable to the measurement of hammers 700 of different sizes, a plurality of workstation slots 410 are arranged at intervals around the tooling seat 400. Each workstation slot 410 is axially arranged on the outer cylindrical surface of the tooling seat 400, and is arranged at intervals in the circumferential direction, and is used to install hammers 700 of different sizes.

[0067] The hammer handle tightening mechanism 500 is used as an extrusion mechanism for the anti-bending test. At least one of the hammer handle tightening mechanism 500 is installed at the top of the right end of the support base 100, and a feed cylinder 580 is provided at one end thereof at the upper left position relative to the tooling seat 400. A pressure block 581 that can abut against the hammer handle of the hammer 700 to be tested is provided on the telescopic shaft of the feed cylinder 580.

[0068] like Fig.18 and Fig.19 As shown, the cross section of the pressing block 581 is V-shaped, which can clamp the hammer handle from both sides to prevent the hammer handle from shifting during the extrusion process. The bending condition of the hammer handle during the test can be accurately measured according to the laser ranging sensor 590.

[0069] In some of the embodiments, Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, the test bench 300 is mainly assembled by a bottom plate 310, a base seat 320, a hammer head locking mechanism 330 and a connecting column 340, which are made of stainless steel, aluminum alloy or plastic and are connected to each other by welding or bolts to form an integrated structure.

[0070] The bottom plate 310 is a vertically arranged square plate-shaped structure, the lower side wall of which is connected to the base seat 320, and at least one fixing hole 311 is opened in the upper part, and the bottom plate 310 is fixedly installed on the left side wall plate of the box body 200 by passing bolts through the fixing holes 311. The base seat 320 is installed at the lower end of the side wall of the bottom plate 310, and the cylindrical groove 321 arranged vertically is opened in the middle, and the top of the cylindrical groove 321 is arranged to penetrate upwards, and is used to accommodate the installation tool seat 400.

[0071] The hammer head locking mechanism 330 adopts a bolt locking method, which is installed at the lower end position of the side wall of the base seat 320, and is used to lock and fix the hammer head of the hammer 700 to be tested installed on the tooling seat 400, forming a limited fixation with the locking abutment point as the supporting tilting point.

[0072] like Figure 2 , Figure 5 , Figure 6and Fig. 9 As shown, in order to prevent the test bench 300 from displacement or tipping over during the test, its bottom is fixed to the support base 100 by a connecting column 340. There is at least one connecting column 340, which is arranged at intervals at the bottom of the base seat 320, and is respectively inserted into the mounting holes 101 at the top of the left end of the support base 100, and is locked and fixed by nuts from the bottom of the support base 100.

[0073] In some of the embodiments, Figure 8 , Fig.10 and Fig.12 As shown, in order to achieve the limit fixation of the tooling seat 400 and prevent the tooling seat 400 from rotating during the test process, causing the hammer 700 to be offset, a square clamping groove 322 is provided at the top of the base seat 320 corresponding to the cylindrical groove 321, and a plurality of first limit posts 323 are provided in the square clamping groove 322; the first limit posts 323 are correspondingly inserted into the first limit slot 421 at the bottom of the square clamping block 420, thereby achieving the limit fixation of the tooling seat 400.

[0074] In addition, as required, a plurality of second limiting posts 324 are provided at the bottom of the cylindrical groove 321, and a plug hole 325 penetrating downward is provided at the center. The second limiting posts 324 are correspondingly inserted into the second limiting grooves 413 spaced apart at the bottom of the work position groove 410, and cooperate with the first limiting posts 323 above to ensure the stability of the installation of the tooling seat 400 in the cylindrical groove 321 from both upper and lower directions.

[0075] In some of the embodiments, Figure 8 , Fig. 9 and Fig.10 As shown, the hammer head locking mechanism 330 is mainly composed of a support column 331, a pressure rod 333, a locking screw 334 and a bottom baffle 335, and is used to press the pressure rod 333 onto the hammer head by rotating the locking screw 334, so as to achieve the purpose of fixing the hammer head.

[0076] Specifically, there are two support columns 331, which are respectively arranged on both sides of the lower end of the cylindrical groove 321, and square adjustment holes 332 are respectively opened on them; the two ends of the pressure rod 333 are movably arranged in the square adjustment holes 332 at both ends, and the ends thereof are abutted and connected with the locking screws 334 threadedly installed on the top of the support columns 331; the bottom baffle 335 is arranged at the bottom of the two support columns 331, and is connected to the bottom end of the base seat 320 as an integrated structure.

[0077] When in use, the tip of the hammer head of the hammer 700 to be tested is inserted into the inner side of the pressure rod 333 from the bottom of the pressure rod 333, the bottom of the hammer head is located in the hammer head slot 411, and the hammer handle is pressed into the work station slot 410. After the hammer 700 to be tested is placed, the locking screw 334 is manually rotated, and one end of the locking screw 334 pushes the pressure rod 333 to tightly abut against the inner side of the hammer head. The feed stroke is to fall off the hammer handle and the bottom of the work station slot 410 to a certain distance, thereby completing the limit fixation of the hammer head. After the test is completed, the locking screw 334 is manually rotated in the opposite direction to take out the hammer 700 to be tested.

[0078] In some of the embodiments, Fig.13 and Fig.14 As shown, a plurality of workstation slots 410 are arranged at intervals on the circumference of the tooling seat 400. The upper end of the workstation slot 410 is upwardly penetrated for placing the hammer handle, and the lower end is provided with a hammer head slot 411 that does not penetrate to the bottom, and the bottom is provided with a second limiting slot 413, which is used for limiting the connection of the test bench 300. It is worth noting that the size and shape of each of the workstation slots 410 and the hammer head slot 411 on the cylindrical circumference of the tooling seat 400 are different, such as the depth, width and shape of each of the workstation slots 410 are different, and the depth, width and shape of the hammer head slot 411 are different, so as to meet the test scenarios of a variety of similar hammers.

[0079] In addition, corresponding to the first limiting columns 323 on the top of the test bench 300, square blocks 420 arranged in a square shape are respectively provided at the four corners of the top of the tooling seat 400, and the bottom of the square blocks 420 is provided with a first limiting groove 421. When the tooling seat 400 is rotated to adjust different station slots 410, the corresponding first limiting columns 323 can be inserted into the first limiting groove 421, so that the tooling seat 400 and the test bench 300 are relatively fixed, ensuring the stability of the tooling seat 400 during the test process.

[0080] In some of the embodiments, Fig.16 As shown, in order to facilitate the adjustment and position fixing of the work position slot 410 on the tooling seat 400, a locking screw 430 and a return spring 440 coaxially sleeved on the upper end of the locking screw 430 are arranged in the central axis hole of the tooling seat 400.

[0081] The lower end of the locking screw 430 passes through the central axis hole and the socket 325 at the bottom of the test bench 300 and is fixedly installed in the corresponding mounting hole 101 of the support base 100 using a nut; the reset spring 440 is located in the spring groove at the upper end of the central axis hole, with its upper end abutting against the locking screw 430 and its lower end abutting against the bottom step connected to the spring groove.

[0082] When in use, the tooling seat 400 is manually stretched upwards, so that the first limiting column 323 at the upper end is separated from the first limiting groove 421, and the second limiting column 324 at the lower end is separated from the second limiting groove 413. At this time, the tooling seat 400 is rotated until the appropriate work slot 410 faces upward. Then the tooling seat 400 is released, and the tooling seat 400 moves downward under the action of its own gravity and the return spring 440, so that the first limiting column 323 at the upper end is inserted into the corresponding first limiting groove 421, and the second limiting column 324 at the lower end is inserted into the corresponding second limiting groove 413, and the switching of the work slot 410 is completed.

[0083] In some of the embodiments, Fig.17 As shown, in order to realize the bending strength test of the hammer handle only, the tooling seat 400 further includes a magnetic support block 450 for supporting the hammer handle of the hammer 700 to be tested. The magnetic support block 450 includes a magnet block 451 at the right bottom and a support gasket 452 disposed on the top of the magnet block 451. The magnet block 451 is embedded in the strip groove 421 at the bottom of the station groove 410, and the support gasket 452 is embedded in the station groove 410.

[0084] When in use, a detachable magnetic support block 450 is arranged in the station slot 410 below the hammer handle, and the hammer handle is supported by the magnetic support block 450 to form a second support point, thereby changing the number and position of the supporting force points of the hammer handle, thereby only testing the bending strength of the hammer handle. At the same time, by adjusting the position of the supporting force points of the magnetic support block 450, the hammer handle can be tested in sections.

[0085] In some of the embodiments, Fig.18 , Fig.19 and Fig. 20 As shown, the hammer handle tightening mechanism 500 has a multi-directional adjustment function, which mainly includes an X-axis slide assembly 510, a Y-axis slide assembly 520, a Z-axis slide assembly 530, a support arm 540, a telescopic arm 550, a telescopic cylinder 560, a fine adjustment slide assembly 570 and a feed cylinder 580. Each slide assembly adopts a commercially available double-guide screw module slide, and the cylinder adopts a commercially available hydraulic cylinder, which is convenient for real-time monitoring of the pressure applied to the hammer handle by the feed cylinder 580 through the hydraulic sensor arranged thereon.

[0086] The X-axis slide assembly 510 is longitudinally fixedly installed at the top position of the left end of the support base 100, and the X-axis slide assembly 510 can be controlled by a hand crank or a servo motor. The Y-axis slide assembly 520 arranged in a horizontal direction is installed on the X-axis slide assembly 510.

The fine adjustment slide assembly 570 is vertically installed on the upper end of the telescopic arm 550, on which the feed cylinder 580 and the laser ranging sensor 590 are installed, and the pressing block 581 is provided on the telescopic rod of the feed cylinder 580.

[0088] When in use, according to the size of the hammer 700 to be tested on the tooling seat 400 and the test position requirements, the feed cylinder 580 at the end can be flexibly adjusted through the X-axis slide assembly 510, the Y-axis slide assembly 520, the Z-axis slide assembly 530, the support arm 540, the telescopic arm 550, the telescopic cylinder 560, and the fine adjustment slide assembly 570 so that it is directly facing the hammer handle of the hammer 700 to be tested. Then, the telescopic rod of the feed cylinder 580 is started to extend, and a certain pressure is applied to the hammer handle, and the pressure is monitored by the pressure sensor.

[0089] As a preferred embodiment, Figure 5 and Figure 6 As shown, in order to improve the test efficiency, the test bench 300 and the tooling seat 400 are two groups, which are respectively installed side by side at the top position of the left end of the support base 100.

In other words, one hammer handle tightening mechanism 500 is used to alternately cooperate with two groups of test benches 300 and tooling seats 400 to realize the test of two groups of hammers 700 to be tested.

[0090] In some of the embodiments, Figure 5 , Figure 6 and Figure 7 As shown, the support base 100 is welded by steel plates, and a plurality of mounting holes 101 are provided at the top of the left end of the support base 100 corresponding to the position of the test bench 300, for fixing and mounting the test bench 300.
